Founded in 1850, the University of Sydney is Australia’s 1st university and is regarded as a single of its most prestigious, ranked as the 27th most trustworthy university in the world. In 2013, it was ranked 38th and in the prime .3% in the QS Globe University Rankings. 5 Nobel or Crafoord laureates have been affiliated with the university as graduates and faculty. The University is colloquially identified as one of Australia’s &quotSandstones&quot, a status similar to that of the &quotIvy League&quot in the United States and the &quotRussell Group&quot in the United Kingdom.

The university’s Coat of Arms, granted by the College of Arms are an amalgamation of the arms of the universities of Oxford and Cambridge, and their essential figures, heraldry and other references to the two ancient universities are sprawled throughout the university in its architecture and character. Its motto, &quotSidere mens eadem mutato&quot translated actually gives &quotThough the stars adjust, the thoughts is the very same&quot, but has been a lot more liberally translated to give, &quotSydney University is actually just Oxford or Cambridge laterally displaced around 12,000 miles&quot.

The 2013 QS Planet University Rankings placed Sydney in the leading 20 in the planet in 11 subjects more than a third of the 30 measured. The University of Sydney was ranked 8th in the planet for Education, 9th in Accounting and Finance and 10th in Law. Moreover, Sydney was placed 12th in English Language and Literature, History and Archaeology, Linguistics and Civil Engineering and Structural Engineering, the highest in Australia of these subjects. Psychology at Sydney was ranked 14th, Pharmacy and Pharmacology, and Communication and Media were ranked 16th, and the Sydney Health-related School was ranked 17th.

Its primary campus has been ranked in the prime ten of the world’s most beautiful universities by the British Everyday Telegraph, The Huffington Post and Disney Pixar, among other individuals such as Oxford and Cambridge and is spread across the inner-city suburbs of Camperdown and Darlington.

The analysis and education hub of the Charles Perkins Centre is a 49,500 square metre state-of-the-art building made to help collaboration and new ways of considering. Opened for Semester 1 of 2014, the new developing comprises a structure of six floors, plus 3 basement levels, and an location of approximately 49,500 square metres – almost twice the surface location of the Sydney Cricket Ground.

Located on the north-west boundary of the University’s Camperdown Campus, bordering St John’s College and subsequent to the Royal Prince Alfred Hospital (RPA) – Sydney’s largest hospital and the teaching hospital of the Sydney Medical School. The hub will play a important function in fostering collaboration and multidisciplinary analysis, generating a analysis and education precinct with hyperlinks to nearby affiliated medical analysis institutes and the hospital.

This creating along with the original sandstone Anderson Stuart health-related school is my new property.

Beauty Can Be Seen in the Pink of an Eye!

These tulips have been opening up to the sun in our garden last spring.

The tulip is a perennial, bulbous plant with showy flowers in the genus Tulipa, of which around 75 wild species are presently accepted and which belongs to the family members Liliaceae.

The genus’s native range extends west to the Iberian Peninsula, by way of North Africa to Greece, the Balkans, Turkey, all through the Levant (Syria, Israel, Palestine, Lebanon, Jordan) and Iran, North to Ukraine, southern Siberia and Mongolia, and east to the Northwest of China. The tulip’s centre of diversity is in the Pamir, Hindu Kush, and Tien Shan mountains. It is a common element of steppe and winter-rain Mediterranean vegetation. A quantity of species and several hybrid cultivars are grown in gardens, as potted plants, or as reduce flowers.

Tulips are spring-blooming perennials that develop from bulbs. Based on the species, tulip plants can be in between four inches (ten cm) and 28 inches (71 cm) high. The tulip’s large flowers usually bloom on scapes with leaves in a rosette at ground level and a single flowering stalk arising from amongst the leaves.Tulip stems have few leaves. Larger species tend to have several leaves. Plants normally have two to six leaves, some species up to 12. The tulip’s leaf is strap-shaped, with a waxy coating, and the leaves are alternately arranged on the stem these fleshy blades are often bluish green in colour. Most tulips make only 1 flower per stem, but a couple of species bear a number of flowers on their scapes (e.g. Tulipa turkestanica). The typically cup or star-shaped tulip flower has 3 petals and 3 sepals, which are often termed tepals due to the fact they are almost identical. These six tepals are frequently marked on the interior surface close to the bases with darker colorings. Tulip flowers come in a wide selection of colors, except pure blue (a number of tulips with &quotblue&quot in the name have a faint violet hue).

The flowers have six distinct, basifixed stamens with filaments shorter than the tepals. Each and every stigma has 3 distinct lobes, and the ovaries are superior, with 3 chambers. The tulip’s seed is a capsule with a leathery covering and an ellipsoid to globe shape. Each capsule includes quite a few flat, disc-shaped seeds in two rows per chamber. These light to dark brown seeds have really thin seed coats and endosperm that does not normally fill the entire seed.

Etymology

The word tulip, first described in western Europe in or around 1554 and seemingly derived from the &quotTurkish Letters&quot of diplomat Ogier Ghiselin de Busbecq, initial appeared in English as tulipa or tulipant, entering the language by way of French: tulipe and its obsolete type tulipan or by way of Contemporary Latin tulīpa, from Ottoman Turkish tülbend (&quotmuslin&quot or &quotgauze&quot), and could be in the end derived from the Persian: دلبند‎ delband (&quotTurban&quot), this name becoming applied simply because of a perceived resemblance of the shape of a tulip flower to that of a turban. This might have been due to a translation error in early instances, when it was trendy in the Ottoman Empire to wear tulips on turbans. The translator possibly confused the flower for the turban.

Tulips are referred to as laleh (from Persian لاله, lâleh) in Persian, Turkish, Arabic, and Bulgarian. In Arabic letters, &quotlaleh&quot is written with the exact same letters as Allah, which is why the flower became a holy symbol. It was also related with the Home of Osman, resulting in tulips being extensively utilized in decorative motifs on tiles, mosques, fabrics, crockery, and so forth. in the Ottoman Empire

Cultivation

Tulip cultivars have typically a number of species in their direct background, but most have been derived from Tulipa suaveolens, usually erroneously listed as Tulipa schrenkii. Tulipa gesneriana is in itself an early hybrid of complicated origin and is most likely not the exact same taxon as was described by Conrad Gesner in the 16th century.

Tulips are indigenous to mountainous locations with temperate climates and require a period of cool dormancy, identified as vernalization. They thrive in climates with extended, cool springs and dry summers. Tulip bulbs imported to warm-winter regions of are often planted in autumn to be treated as annuals.

Tulip bulbs are usually planted around late summer season and fall, in properly-drained soils, typically from 4 to 8 inches (ten to 20 cm) deep, based on the kind. Species tulips are typically planted deeper.

Propagation

Tulips can be propagated by means of bulb offsets, seeds or micropropagation. Offsets and tissue culture methods are indicates of asexual propagation for producing genetic clones of the parent plant, which maintains cultivar genetic integrity. Seeds are most typically employed to propagate species and subspecies or to generate new hybrids. Many tulip species can cross-pollinate with every single other, and when wild tulip populations overlap geographically with other tulip species or subspecies, they typically hybridize and create mixed populations. Most industrial tulip cultivars are complex hybrids, and usually sterile.

Offsets need a year or more of growth ahead of plants are big adequate to flower. Tulips grown from seeds frequently need 5 to eight years just before plants are of flowering size. Industrial growers usually harvest the tulip bulbs in late summer time and grade them into sizes bulbs huge sufficient to flower are sorted and sold, whilst smaller bulbs are sorted into sizes and replanted for sale in the future. The Netherlands are the world’s major producer of commercial tulip plants, generating as many as three billion bulbs annually, the majority for export.

Evidence for Recent Liquid Water on Mars

Image by NASA on The Commons
Description: This image, acquired by the Mars International Surveyor (MGS) Mars Orbiter Camera (MOC) in Might 2000 shows quite a few examples of martian gullies that all start–or head–in a specific layer roughly a hundred meters beneath the surface of Mars. These attributes are situated on the south-facing wall of a trough in the Gorgonum Chaos area, an region identified to have a lot of examples of gullies proposed to have formed by seepage and runoff of liquid water in recent martian occasions. The layer from which the gullies emanate has recessed backward to type an overhang beneath a harder layer of rock. The bigger gullies have formed an alcove–an area above the overhang from which debris has collapsed to leave a dark-toned scar. Under the layer of seepage is located a dark, narrow channel that runs down the slope to an apron of debris. The little, bright, parallel characteristics at the base of the cliff at the center-correct of the picture is a series of large windblown ripples. Though the dark tone of the alcoves and channels in this image is not probably to be the result of wet ground (the contrast in this image has been enhanced), it does suggest that water has seeped out of the ground and moved down the slope very not too long ago. Sharp contrasts in between dark and light places are hard to preserve on Mars for really long periods of time due to the fact dust tends to coat surfaces and minimize brightness differences. To preserve dust from settling on a surface, it has to have undergone some procedure of erosion (wind, landslides, water runoff) comparatively not too long ago. There is no way to know how current this activity was, but educated guesses center among a couple of to tens of years, and it is totally possible that the location shown in this image has water seeping out of the ground right now. Centered close to 37.9S, 170.2W, sunlight illuminates the MOC image from the upper left, north is toward the upper right.

Quoting from Wikipedia | Space Shuttle Enterprise:

The Space Shuttle Enterprise (NASA Orbiter Automobile Designation: OV-101) was the first Space Shuttle orbiter. It was built for NASA as component of the Space Shuttle plan to perform test flights in the atmosphere. It was constructed with no engines or a functional heat shield, and was therefore not capable of spaceflight.

Initially, Enterprise had been intended to be refitted for orbital flight, which would have produced it the second space shuttle to fly soon after Columbia. Nevertheless, throughout the construction of Columbia, information of the final design and style changed, especially with regard to the weight of the fuselage and wings. Refitting Enterprise for spaceflight would have involved dismantling the orbiter and returning the sections to subcontractors across the nation. As this was an expensive proposition, it was determined to be significantly less costly to construct Challenger around a body frame (STA-099) that had been developed as a test article. Similarly, Enterprise was regarded as for refit to replace Challenger right after the latter was destroyed, but Endeavour was built from structural spares as an alternative.

Service

Building started on the initial orbiter on June 4, 1974. Designated OV-101, it was originally planned to be named Constitution and unveiled on Constitution Day, September 17, 1976. A write-in campaign by Trekkies to President Gerald Ford asked that the orbiter be named following the Starship Enterprise, featured on the tv show Star Trek. Despite the fact that Ford did not mention the campaign, the president—who throughout Globe War II had served on the aircraft carrier USS&nbspMonterey&nbsp(CVL-26) that served with USS&nbspEnterprise&nbsp(CV-6)—said that he was &quotpartial to the name&quot and overrode NASA officials.

The style of OV-101 was not the exact same as that planned for OV-102, the initial flight model the tail was constructed differently, and it did not have the interfaces to mount OMS pods. A massive quantity of subsystems—ranging from main engines to radar equipment—were not installed on this vehicle, but the capacity to add them in the future was retained. Rather of a thermal protection technique, its surface was primarily fiberglass.

In mid-1976, the orbiter was utilised for ground vibration tests, permitting engineers to evaluate information from an actual flight automobile with theoretical models.

On September 17, 1976, Enterprise was rolled out of Rockwell’s plant at Palmdale, California. In recognition of its fictional namesake, Star Trek creator Gene Roddenberry and most of the principal cast of the original series of Star Trek had been on hand at the dedication ceremony.

Strategy and landing tests (ALT)

Main article: Strategy and Landing Tests

On January 31, 1977, it was taken by road to Dryden Flight Study Center at Edwards Air Force Base, to commence operational testing.

While at NASA Dryden, Enterprise was utilized by NASA for a variety of ground and flight tests intended to validate aspects of the shuttle system. The initial nine-month testing period was referred to by the acronym ALT, for &quotApproach and Landing Test&quot. These tests integrated a maiden &quotflight&quot on February 18, 1977 atop a Boeing 747 Shuttle Carrier Aircraft (SCA) to measure structural loads and ground handling and braking traits of the mated method. Ground tests of all orbiter subsystems had been carried out to confirm functionality prior to atmospheric flight.

The mated Enterprise/SCA combination was then subjected to 5 test flights with Enterprise unmanned and unactivated. The objective of these test flights was to measure the flight qualities of the mated mixture. These tests had been followed with three test flights with Enterprise manned to test the shuttle flight manage systems.

Enterprise underwent five totally free flights where the craft separated from the SCA and was landed beneath astronaut manage. These tests verified the flight qualities of the orbiter design and were carried out under a number of aerodynamic and weight configurations. On the fifth and final glider flight, pilot-induced oscillation difficulties had been revealed, which had to be addressed before the first orbital launch occurred.

On August 12, 1977, the space shuttle Enterprise flew on its personal for the 1st time.

Preparation for STS-1

Following the ALT plan, Enterprise was ferried among a number of NASA facilities to configure the craft for vibration testing. In June 1979, it was mated with an external tank and solid rocket boosters (known as a boilerplate configuration) and tested in a launch configuration at Kennedy Space Center Launch Pad 39A.

Retirement

With the completion of vital testing, Enterprise was partially disassembled to let certain elements to be reused in other shuttles, then underwent an international tour going to France, Germany, Italy, the United Kingdom, Canada, and the U.S. states of California, Alabama, and Louisiana (during the 1984 Louisiana Globe Exposition). It was also employed to match-verify the never ever-employed shuttle launch pad at Vandenberg AFB, California. Finally, on November 18, 1985, Enterprise was ferried to Washington, D.C., exactly where it became property of the Smithsonian Institution.

Post-Challenger

Right after the Challenger disaster, NASA regarded making use of Enterprise as a replacement. However refitting the shuttle with all of the essential equipment needed for it to be utilised in space was regarded as, but as an alternative it was decided to use spares constructed at the same time as Discovery and Atlantis to develop Endeavour.

Post-Columbia

In 2003, right after the breakup of Columbia in the course of re-entry, the Columbia Accident Investigation Board performed tests at Southwest Research Institute, which employed an air gun to shoot foam blocks of similar size, mass and speed to that which struck Columbia at a test structure which mechanically replicated the orbiter wing leading edge. They removed a fiberglass panel from Enterprise’s wing to perform analysis of the material and attached it to the test structure, then shot a foam block at it. Although the panel was not broken as a result of the test, the influence was enough to permanently deform a seal. As the reinforced carbon-carbon (RCC) panel on Columbia was 2.5 times weaker, this recommended that the RCC major edge would have been shattered. Additional tests on the fiberglass had been canceled in order not to threat damaging the test apparatus, and a panel from Discovery was tested to decide the effects of the foam on a similarly-aged RCC leading edge. On July 7, 2003, a foam effect test produced a hole 41&nbspcm by 42.five&nbspcm (16.1&nbspinches by 16.7&nbspinches) in the protective RCC panel. The tests clearly demonstrated that a foam impact of the variety Columbia sustained could seriously breach the protective RCC panels on the wing major edge.

The board determined that the probable lead to of the accident was that the foam influence triggered a breach of a reinforced carbon-carbon panel along the top edge of Columbia’s left wing, permitting hot gases generated in the course of re-entry to enter the wing and cause structural collapse. This brought on Columbia to spin out of handle, breaking up with the loss of the complete crew.

Museum exhibit

Enterprise was stored at the Smithsonian’s hangar at Washington Dulles International Airport prior to it was restored and moved to the newly constructed Smithsonian’s National Air and Space Museum‘s Steven F. Udvar-Hazy Center at Dulles International Airport, where it has been the centerpiece of the space collection. On April 12, 2011, NASA announced that Space Shuttle Discovery, the most traveled orbiter in the fleet, will be added to the collection once the Shuttle fleet is retired. When that happens, Enterprise will be moved to the Intrepid Sea-Air-Space Museum in New York City, to a newly constructed hangar adjacent to the museum. In preparation for the anticipated relocation, engineers evaluated the automobile in early 2010 and determined that it was protected to fly on the Shuttle Carrier Aircraft once once more.

The initial nine-month testing period was referred to by the acronym ALT, for &quotApproach and Landing Test&quot. These tests integrated a maiden &quotflight&quot on February 18, 1977 atop a Boeing 747 Shuttle Carrier Aircraft (SCA) to measure structural loads and ground handling and braking traits of the mated program. Ground tests of all orbiter subsystems had been carried out to confirm functionality prior to atmospheric flight.

The mated Enterprise/SCA combination was then subjected to five test flights with Enterprise unmanned and unactivated. The objective of these test flights was to measure the flight traits of the mated mixture. These tests had been followed with 3 test flights with Enterprise manned to test the shuttle flight handle systems.

Enterprise underwent 5 free flights where the craft separated from the SCA and was landed beneath astronaut handle. These tests verified the flight traits of the orbiter design and have been carried out under numerous aerodynamic and weight configurations. On the fifth and final glider flight, pilot-induced oscillation problems have been revealed, which had to be addressed ahead of the 1st orbital launch occurred.

On August 12, 1977, the space shuttle Enterprise flew on its own for the initial time.

Preparation for STS-1

Following the ALT plan, Enterprise was ferried among many NASA facilities to configure the craft for vibration testing. In June 1979, it was mated with an external tank and solid rocket boosters (identified as a boilerplate configuration) and tested in a launch configuration at Kennedy Space Center Launch Pad 39A.

Retirement

With the completion of crucial testing, Enterprise was partially disassembled to enable certain components to be reused in other shuttles, then underwent an international tour going to France, Germany, Italy, the United Kingdom, Canada, and the U.S. states of California, Alabama, and Louisiana (for the duration of the 1984 Louisiana World Exposition). It was also utilized to match-check the by no means-utilized shuttle launch pad at Vandenberg AFB, California. Lastly, on November 18, 1985, Enterprise was ferried to Washington, D.C., where it became home of the Smithsonian Institution.

Post-Challenger

Right after the Challenger disaster, NASA regarded as using Enterprise as a replacement. However refitting the shuttle with all of the required gear required for it to be employed in space was regarded as, but instead it was decided to use spares constructed at the identical time as Discovery and Atlantis to construct Endeavour.

Post-Columbia

In 2003, following the breakup of Columbia in the course of re-entry, the Columbia Accident Investigation Board performed tests at Southwest Investigation Institute, which used an air gun to shoot foam blocks of equivalent size, mass and speed to that which struck Columbia at a test structure which mechanically replicated the orbiter wing top edge. They removed a fiberglass panel from Enterprise’s wing to execute analysis of the material and attached it to the test structure, then shot a foam block at it. Although the panel was not broken as a result of the test, the effect was adequate to permanently deform a seal. As the reinforced carbon-carbon (RCC) panel on Columbia was two.5 times weaker, this suggested that the RCC top edge would have been shattered. Additional tests on the fiberglass had been canceled in order not to danger damaging the test apparatus, and a panel from Discovery was tested to figure out the effects of the foam on a similarly-aged RCC top edge. On July 7, 2003, a foam influence test produced a hole 41&nbspcm by 42.five&nbspcm (16.1&nbspinches by 16.7&nbspinches) in the protective RCC panel. The tests clearly demonstrated that a foam effect of the kind Columbia sustained could seriously breach the protective RCC panels on the wing leading edge.

The board determined that the probable lead to of the accident was that the foam effect caused a breach of a reinforced carbon-carbon panel along the leading edge of Columbia’s left wing, allowing hot gases generated in the course of re-entry to enter the wing and lead to structural collapse. This caused Columbia to spin out of manage, breaking up with the loss of the complete crew.

Museum exhibit

Enterprise was stored at the Smithsonian’s hangar at Washington Dulles International Airport before it was restored and moved to the newly built Smithsonian’s National Air and Space Museum‘s Steven F. Udvar-Hazy Center at Dulles International Airport, exactly where it has been the centerpiece of the space collection. On April 12, 2011, NASA announced that Space Shuttle Discovery, the most traveled orbiter in the fleet, will be added to the collection when the Shuttle fleet is retired. When that takes place, Enterprise will be moved to the Intrepid Sea-Air-Space Museum in New York City, to a newly constructed hangar adjacent to the museum. In preparation for the anticipated relocation, engineers evaluated the vehicle in early 2010 and determined that it was secure to fly on the Shuttle Carrier Aircraft as soon as again.

Brunswick Centre ‘Aqua/duct ‘ is the result of function by the artist Susanna Heron in collaboration with Levitt Bernstein Associates Architects.
The introduction of water to the Brunswick Centre by artist Susanna Heron was an integral portion of the refurbishment in 2006 and a requirement of the 106 Agreement which was a situation of Planning with Camden Council.
The Operate was created in response to the central public space and acts as a structural backbone or a connecting ‘hinge’ between the shops and flights of flats on either side. A series of stainless steel troughs mark this central spine channelling fast flowing water towards a huge pool. The longitudinal units interact with the cellular structure of the Brunswick Centre, the pacing of the troughs creates a transparency of movement for folks to move across the space and the pool marks the intersection.
The stainless steel water-troughs appear utilitarian, industrial, out-of-doors and man-made they rest under their personal weight, their surfaces unrefined. The steel is folded to decrease the need for welds creating curves effortless to lean over and a continuous structural ‘skin’ which provides it strength.
A rectangular pool is situated at the T-junction in between the Renoir Cinema and the central space. The container for the pool is low adequate to encourage men and women to sit collectively along the edges. This container is similarly angled and rests on the ground to trap the water in its frame. Circular lights set flush with the pool-base are illuminated at night appearing to float beneath the surface while by day the water draws in the sky.

Dimensions:
Overall: 57 ft. tall x 122 ft. extended x 78 ft. wing span, 150,000 lb.
(1737.36 x 3718.57 x 2377.44cm, 68039.6kg)

Materials:
Aluminum airframe and body with some fiberglass characteristics payload bay doors are graphite epoxy composite thermal tiles are simulated (polyurethane foam) except for test samples of actual tiles and thermal blankets.

The very first Space Shuttle orbiter, &quotEnterprise,&quot is a complete-scale test car employed for flights in the atmosphere and tests on the ground it is not equipped for spaceflight. Even though the airframe and flight handle components are like those of the Shuttles flown in space, this vehicle has no propulsion system and only simulated thermal tiles due to the fact these attributes had been not required for atmospheric and ground tests. &quotEnterprise&quot was rolled out at Rockwell International’s assembly facility in Palmdale, California, in 1976. In 1977, it entered service for a nine-month-extended method-and-landing test flight program. Thereafter it was used for vibration tests and fit checks at NASA centers, and it also appeared in the 1983 Paris Air Show and the 1984 World’s Fair in New Orleans. In 1985, NASA transferred &quotEnterprise&quot to the Smithsonian Institution’s National Air and Space Museum.

Quoting from Wikipedia | Space Shuttle Enterprise:

The Space Shuttle Enterprise (NASA Orbiter Vehicle Designation: OV-101) was the 1st Space Shuttle orbiter. It was built for NASA as portion of the Space Shuttle plan to perform test flights in the atmosphere. It was constructed without having engines or a functional heat shield, and was therefore not capable of spaceflight.

Initially, Enterprise had been intended to be refitted for orbital flight, which would have made it the second space shuttle to fly following Columbia. Nonetheless, in the course of the building of Columbia, details of the final style changed, especially with regard to the weight of the fuselage and wings. Refitting Enterprise for spaceflight would have involved dismantling the orbiter and returning the sections to subcontractors across the country. As this was an expensive proposition, it was determined to be significantly less costly to develop Challenger about a body frame (STA-099) that had been produced as a test post. Similarly, Enterprise was regarded as for refit to replace Challenger after the latter was destroyed, but Endeavour was built from structural spares alternatively.

Service

Construction started on the 1st orbiter on June four, 1974. Designated OV-101, it was initially planned to be named Constitution and unveiled on Constitution Day, September 17, 1976. A create-in campaign by Trekkies to President Gerald Ford asked that the orbiter be named soon after the Starship Enterprise, featured on the tv show Star Trek. Although Ford did not mention the campaign, the president—who throughout World War II had served on the aircraft carrier USS&nbspMonterey&nbsp(CVL-26) that served with USS&nbspEnterprise&nbsp(CV-six)—said that he was &quotpartial to the name&quot and overrode NASA officials.

The style of OV-101 was not the identical as that planned for OV-102, the initial flight model the tail was constructed differently, and it did not have the interfaces to mount OMS pods. A big number of subsystems—ranging from major engines to radar equipment—were not installed on this vehicle, but the capacity to add them in the future was retained. Instead of a thermal protection technique, its surface was primarily fiberglass.

In mid-1976, the orbiter was used for ground vibration tests, permitting engineers to evaluate data from an actual flight automobile with theoretical models.

On September 17, 1976, Enterprise was rolled out of Rockwell’s plant at Palmdale, California. In recognition of its fictional namesake, Star Trek creator Gene Roddenberry and most of the principal cast of the original series of Star Trek were on hand at the dedication ceremony.

Satellite Image Shows the Snow-covered U.S. Deep Freeze

Image by NASA Goddard Photo and Video
NOAA’s GOES-East satellite offered a appear at the frigid eastern two-thirds of the U.S. on Jan. 7, 2015, that shows a blanket of northern snow, lake-effect snow from the Excellent Lakes and clouds behind the Arctic cold front.

A visible picture captured at 1600 UTC (11 a.m. EST) showed the effects of the most current Arctic outbreak. The cold front that brought the Arctic air has moved as far south as Florida, and stretches back over the Gulf of Mexico and just west of Texas today. The image shows clouds behind the frontal boundary stretching from the Carolinas west more than the Heartland. Farther north, a wide band of fallen snow covers the ground from New England west to Montana, with rivers appearing like veins. The GOES-East satellite image also shows wind-whipped lake-impact snows off the Wonderful Lakes, blowing to the southeast. Meanwhile, Florida, the nation’s warm spot appeared virtually cloud-totally free.

To produce the image, NASA/NOAA’s GOES Project employed cloud data from NOAA’s GOES-East satellite and overlaid it on a correct-colour image of land and ocean produced by data from the Moderate Resolution Imaging Spectroradiometer, or MODIS, instrument that flies aboard NASA’s Aqua and Terra satellites. Collectively, those information developed the whole picture of the Arctic outbreak.

The forecast from NOAA’s National Weather Service Weather Prediction Center (WPC) calls for a lot more snow along the Appalachian Mountains from Tennessee north to upstate New York. Snow is also expected to fall from New England west to Montana, and in eastern New Mexico and the Colorado Rockies. The WPC summary for Jan. 7 noted: Bitter cold will be felt from the western High Plains to the Mid-Atlantic and Northeast U.S. for the subsequent few days. Widespread subzero overnight lows are forecast for the Dakotas, Upper Midwest, Fantastic Lakes, and interior New England. Wind Chill Advisories and Warnings are in effect for numerous of these areas.

GOES-East offers visible and infrared photos more than the eastern U.S. and the Atlantic Ocean from its fixed orbit in space. NOAA’s GOES satellites give the sort of continuous monitoring required for intensive information analysis. Geostationary describes an orbit in which a satellite is constantly in the exact same position with respect to the rotating Earth. This enables GOES to hover continuously more than one particular position on Earth’s surface, appearing stationary. As a outcome, GOES provide a continual vigil for the atmospheric triggers for serious climate situations such as tornadoes, flash floods, hail storms and hurricanes.

City Lights of the United States 2012

Image by NASA Goddard Photo and Video
NASA image acquired April 18 – October 23, 2012

This image of the United States of America at evening is a composite assembled from information acquired by the Suomi NPP satellite in April and October 2012. The image was produced possible by the new satellite’s “day-evening band” of the Visible Infrared Imaging Radiometer Suite (VIIRS), which detects light in a range of wavelengths from green to near-infrared and makes use of filtering tactics to observe dim signals such as city lights, gas flares, auroras, wildfires, and reflected moonlight.

“Nighttime light is the most interesting information that I’ve had a opportunity to operate with,” says Chris Elvidge, who leads the Earth Observation Group at NOAA’s National Geophysical Information Center. “I’m often amazed at what city light photos show us about human activity.” His research group has been approached by scientists looking for to model the distribution of carbon dioxide emissions from fossil fuels and to monitor the activity of industrial fishing fleets. Biologists have examined how urban development has fragmented animal habitat. Elvidge even learned once of a study of dictatorships in numerous parts of the world and how nighttime lights had a tendency to expand in the dictator’s hometown or province.

Named for satellite meteorology pioneer Verner Suomi, NPP flies more than any offered point on Earth’s surface twice each day at roughly 1:30 a.m. and p.m. The polar-orbiting satellite flies 824 kilometers (512 miles) above the surface, sending its data after per orbit to a ground station in Svalbard, Norway, and continuously to local direct broadcast users distributed about the globe. Suomi NPP is managed by NASA with operational help from NOAA and its Joint Polar Satellite System, which manages the satellite’s ground technique.

Preparing For Antarctic Flights in the California Desert

Image by NASA Goddard Space Flight Center
At first glance a dry lake bed in the southern California desert appears like the last place to prepare to study ice. But on Oct. two, 2014, NASA’s Operation IceBridge carried out a ground-primarily based GPS survey of the El Mirage lake bed in California’s Mojave Desert. Members of the IceBridge group are at the moment at NASA’s Armstrong Flight Investigation Center, preparing instruments aboard the DC-8 study aircraft for flights more than Antarctica.

Element of this preparation includes test flights more than the desert, exactly where researchers verify their instruments are operating effectively. El Mirage serves as a prime place for testing the mission’s laser altimeter, the Airborne Topographic Mapper, due to the fact the lake bed has a flat surface and reflects light similarly to snow and ice.

This photo, taken shortly right after the survey, shows the GPS-equipped survey car and a stationary GPS station (left of the car) on the lake bed with the constellation Ursa Major in the background. By driving the vehicle in parallel back and forth lines more than a predefined region and comparing these GPS elevation readings with measurements from the stationary GPS, researchers are in a position to create an elevation map that will be used to precisely calibrate the laser altimeter for ice measurements.

Operation IceBridge is scheduled to start investigation flights more than Antarctica on Oct. 15, 2014. The mission will be primarily based out of Punta Arenas, Chile, till Nov. 23.

Details, quoting from Smithsonian National Air and Space Museum | Vought F4U-1D Corsair:

By V-J Day, September 2, 1945, Corsair pilots had amassed an 11:1 kill ratio against enemy aircraft. The aircraft’s distinctive inverted gull-wing design allowed ground clearance for the huge, three-bladed Hamilton Standard Hydromatic propeller, which spanned more than 4 meters (13 feet). The Pratt and Whitney R-2800 radial engine and Hydromatic propeller was the largest and one of the most powerful engine-propeller combinations ever flown on a fighter aircraft.

Charles Lindbergh flew bombing missions in a Corsair with Marine Air Group 31 against Japanese strongholds in the Pacific in 1944. This airplane is painted in the colors and markings of the Corsair Sun Setter, a Marine close-support fighter assigned to the USS Essex in July 1944.

Transferred from the United States Navy.

Manufacturer:
Vought Aircraft Company

Date:
1940

Country of Origin:
United States of America

Dimensions:
Overall: 460 x 1020cm, 4037kg, 1250cm (15ft 1 1/8in. x 33ft 5 9/16in., 8900lb., 41ft 1/8in.)

Materials:
All metal with fabric-covered wings behind the main spar.

Physical Description:
R-2800 radial air-cooled engine with 1,850 horsepower, turned a three-blade Hamilton Standard Hydromatic propeller with solid aluminum blades spanning 13 feet 1 inch; wing bent gull-shaped on both sides of the fuselage.

Long Description:
On February 1, 1938, the United States Navy Bureau of Aeronautics requested proposals from American aircraft manufacturers for a new carrier-based fighter airplane. During April, the Vought Aircraft Corporation responded with two designs and one of them, powered by a Pratt & Whitney R-2800 engine, won the competition in June. Less than a year later, Vought test pilot Lyman A. Bullard, Jr., first flew the Vought XF4U-1 prototype on May 29, 1940. At that time, the largest engine driving the biggest propeller ever flown on a fighter aircraft propelled Bullard on this test flight. The R-2800 radial air-cooled engine developed 1,850 horsepower and it turned a three-blade Hamilton Standard Hydromatic propeller with solid aluminum blades spanning 13 feet 1 inch.

The airplane Bullard flew also had another striking feature, a wing bent gull-shaped on both sides of the fuselage. This arrangement gave additional ground clearance for the propeller and reduced drag at the wing-to-fuselage joint. Ironically for a 644-kph (400 mph) airplane, Vought covered the wing with fabric behind the main spar, a practice the company also followed on the OS2U Kingfisher (see NASM collection).

When naval air strategists had crafted the requirements for the new fighter, the need for speed had overridden all other performance goals. With this in mind, the Bureau of Aeronautics selected the most powerful air-cooled engine available, the R-2800. Vought assembled a team, lead by chief designer Rex Biesel, to design the best airframe around this powerful engine. The group included project engineer Frank Albright, aerodynamics engineer Paul Baker, and propulsion engineer James Shoemaker. Biesel and his team succeeded in building a very fast fighter but when they redesigned the prototype for production, they were forced to make an unfortunate compromise.

The Navy requested heavier armament for production Corsairs and Biesel redesigned each outboard folding wing panel to carry three .50 caliber machine guns. These guns displaced fuel tanks installed in each wing leading edge. To replace this lost capacity, an 897-liter (237 gal) fuselage tank was installed between the cockpit and the engine. To maintain the speedy and narrow fuselage profile, Biesel could not stack the cockpit on top of the tank, so he moved it nearly three feet aft. Now the wing completely blocked the pilot’s line of sight during the most critical stages of landing. The early Corsair also had a vicious stall, powerful torque and propeller effects at slow speed, a short tail wheel strut, main gear struts that often bounced the airplane at touchdown, and cowl flap actuators that leaked oil onto the windshield. These difficulties, combined with the lack of cockpit visibility, made the airplane nearly impossible to land on the tiny deck of an aircraft carrier. Navy pilots soon nicknamed the F4U the ‘ensign eliminator’ for its tendency to kill these inexperienced aviators. The Navy refused to clear the F4U for carrier operations until late in 1944, more than seven years after the project started.

This flaw did not deter the Navy from accepting Corsairs because Navy and Marine pilots sorely needed an improved fighter to replace the Grumman F4F Wildcat (see NASM collection). By New Year’s Eve, 1942, the service owned 178 F4U-1 airplanes. Early in 1943, the Navy decided to divert all Corsairs to land-based United States Marine Corps squadrons and fill Navy carrier-based units with the Grumman F6F Hellcat (see NASM collection). At its best speed of 612 kph (380 mph) at 6,992 m (23,000 ft), the Hellcat was about 24 kph (15 mph) slower than the Corsair but it was a joy to fly aboard the carrier. The F6F filled in splendidly until improvements to the F4U qualified it for carrier operations. Meanwhile, the Marines on Guadalcanal took their Corsairs into combat and engaged the enemy for the first time on February 14, 1943, six months before Hellcat pilots on that battle-scared island first encountered enemy aircraft.

The F4U had an immediate impact on the Pacific air war. Pilots could use the Corsair’s speed and firepower to engage the more maneuverable Japanese airplanes only when the advantage favored the Americans. Unprotected by armor or self-sealing fuel tanks, no Japanese fighter or bomber could withstand for more than a few seconds the concentrated volley from the six .50 caliber machine guns carried by a Corsair. Major Gregory "Pappy" Boyington assumed command of Marine Corsair squadron VMF-214, nicknamed the ‘Black Sheep’ squadron, on September 7, 1943. During less than 5 months of action, Boyington received credit for downing 28 enemy aircraft. Enemy aircraft shot him down on January 3, 1944, but he survived the war in a Japanese prison camp.

In May and June 1944, Charles A. Lindbergh flew Corsair missions with Marine pilots at Green Island and Emirau. On September 3, 1944, Lindbergh demonstrated the F4U’s bomb hauling capacity by flying a Corsair from Marine Air Group 31 carrying three bombs each weighing 450 kg (1,000 lb). He dropped this load on enemy positions at Wotje Atoll. On the September 8, Lindbergh dropped the first 900-kg (2,000 lb) bomb during an attack on the atoll. For the finale five days later, the Atlantic flyer delivered a 900-kg (2,000 lb) bomb and two 450-kg (1,000 lb) bombs. Lindbergh went ahead and flew these missions after the commander of MAG-31 informed him that if he was forced down and captured, the Japanese would almost certainly execute him.

As of V-J Day, September 2, 1945, the Navy credited Corsair pilots with destroying 2,140 enemy aircraft in aerial combat. The Navy and Marines lost 189 F4Us in combat and 1,435 Corsairs in non-combat accidents. Beginning on February 13, 1942, Marine and Navy pilots flew 64,051 operational sorties, 54,470 from runways and 9,581 from carrier decks. During the war, the British Royal Navy accepted 2,012 Corsairs and the Royal New Zealand Air Force accepted 364. The demand was so great that the Goodyear Aircraft Corporation and the Brewster Aeronautical Corporation also produced the F4U.

Corsairs returned to Navy carrier decks and Marine airfields during the Korean War. On September 10, 1952, Captain Jesse Folmar of Marine Fighter Squadron VMF-312 destroyed a MiG-15 in aerial combat over the west coast of Korea. However, F4U pilots did not have many air-to-air encounters over Korea. Their primary mission was to support Allied ground units along the battlefront.

After the World War II, civilian pilots adapted the speedy bent-wing bird from Vought to fly in competitive air races. They preferred modified versions of the F2G-1 and -2 originally built by Goodyear. Corsairs won the prestigious Thompson Trophy twice. In 1952, Vought manufactured 94 F4U-7s for the French Navy, and these aircraft saw action over Indochina but this order marked the end of Corsair production. In production longer than any other U.S. fighter to see service in World War II, Vought, Goodyear, and Brewster built a total of 12,582 F4Us.

The United States Navy donated an F4U-1D to the National Air and Space Museum in September 1960. Vought delivered this Corsair, Bureau of Aeronautics serial number 50375, to the Navy on April 26, 1944. By October, pilots of VF-10 were flying it but in November, the airplane was transferred to VF-89 at Naval Air Station Atlantic City. It remained there as the squadron moved to NAS Oceana and NAS Norfolk. During February 1945, the Navy withdrew the airplane from active service and transferred it to a pool of surplus aircraft stored at Quantico, Virginia. In 1980, NASM craftsmen restored the F4U-1D in the colors and markings of a Corsair named "Sun Setter," a fighter assigned to Marine Fighter Squadron VMF-114 when that unit served aboard the "USS Essex" in July 1944.

Quoting from Wikipedia | Vought F4U Corsair:

The Chance Vought F4U Corsair was a carrier-capable fighter aircraft that saw service primarily in World War II and the Korean War. Demand for the aircraft soon overwhelmed Vought’s manufacturing capability, resulting in production by Goodyear and Brewster: Goodyear-built Corsairs were designated FG and Brewster-built aircraft F3A. From the first prototype delivery to the U.S. Navy in 1940, to final delivery in 1953 to the French, 12,571 F4U Corsairs were manufactured by Vought, in 16 separate models, in the longest production run of any piston-engined fighter in U.S. history (1942–1953).

The Corsair served in the U.S. Navy, U.S. Marines, Fleet Air Arm and the Royal New Zealand Air Force, as well as the French Navy Aeronavale and other, smaller, air forces until the 1960s. It quickly became the most capable carrier-based fighter-bomber of World War II. Some Japanese pilots regarded it as the most formidable American fighter of World War II, and the U.S. Navy counted an 11:1 kill ratio with the F4U Corsair.

F4U-1D (Corsair Mk IV): Built in parallel with the F4U-1C, but was introduced in April 1944. It had the new -8W water-injection engine. This change gave the aircraft up to 250 hp (190 kW) more power, which, in turn, increased performance. Speed, for example, was boosted from 417 miles per hour (671 km/h) to 425 miles per hour (684 km/h). Because of the U.S. Navy’s need for fighter-bombers, it had a payload of rockets double the -1A’s, as well as twin-rack plumbing for an additional belly drop tank. Such modifications necessitated the need for rocket tabs (attached to fully metal-plated underwing surfaces) and bomb pylons to be bolted on the fighter, however, causing extra drag. Additionally, the role of fighter-bombing was a new task for the Corsair and the wing fuel cells proved too vulnerable and were removed.[] The extra fuel carried by the two drop tanks would still allow the aircraft to fly relatively long missions despite the heavy, un-aerodynamic load. The regular armament of six machine guns were implemented as well. The canopies of most -1Ds had their struts removed along with their metal caps, which were used — at one point — as a measure to prevent the canopies’ glass from cracking as they moved along the fuselage spines of the fighters.[] Also, the clear-view style "Malcolm Hood" canopy used initially on Supermarine Spitfire and P-51C Mustang aircraft was adopted as standard equipment for the -1D model, and all later F4U production aircraft. Additional production was carried out by Goodyear (FG-1D) and Brewster (F3A-1D). In Fleet Air Arm service, the latter was known as the Corsair III, and both had their wingtips clipped by 8" per wing to allow storage in the lower hangars of British carriers.

Quoting Smithsonian National Air and Space Museum | Concorde, Fox Alpha, Air France:

The first supersonic airliner to enter service, the Concorde flew thousands of passengers across the Atlantic at twice the speed of sound for over 25 years. Designed and built by Aérospatiale of France and the British Aviation Corporation, the graceful Concorde was a stunning technological achievement that could not overcome serious economic problems.

In 1976 Air France and British Airways jointly inaugurated Concorde service to destinations around the globe. Carrying up to 100 passengers in great comfort, the Concorde catered to first class passengers for whom speed was critical. It could cross the Atlantic in fewer than four hours – half the time of a conventional jet airliner. However its high operating costs resulted in very high fares that limited the number of passengers who could afford to fly it. These problems and a shrinking market eventually forced the reduction of service until all Concordes were retired in 2003.

In 1989, Air France signed a letter of agreement to donate a Concorde to the National Air and Space Museum upon the aircraft’s retirement. On June 12, 2003, Air France honored that agreement, donating Concorde F-BVFA to the Museum upon the completion of its last flight. This aircraft was the first Air France Concorde to open service to Rio de Janeiro, Washington, D.C., and New York and had flown 17,824 hours.

Details, quoting from Smithsonian National Air and Space Museum | Lockheed SR-71 Blackbird:

No reconnaissance aircraft in history has operated globally in more hostile airspace or with such complete impunity than the SR-71, the world’s fastest jet-propelled aircraft. The Blackbird’s performance and operational achievements placed it at the pinnacle of aviation technology developments during the Cold War.

This Blackbird accrued about 2,800 hours of flight time during 24 years of active service with the U.S. Air Force. On its last flight, March 6, 1990, Lt. Col. Ed Yielding and Lt. Col. Joseph Vida set a speed record by flying from Los Angeles to Washington, D.C., in 1 hour, 4 minutes, and 20 seconds, averaging 3,418 kilometers (2,124 miles) per hour. At the flight’s conclusion, they landed at Washington-Dulles International Airport and turned the airplane over to the Smithsonian.

Long Description:
No reconnaissance aircraft in history has operated in more hostile airspace or with such complete impunity than the SR-71 Blackbird. It is the fastest aircraft propelled by air-breathing engines. The Blackbird’s performance and operational achievements placed it at the pinnacle of aviation technology developments during the Cold War. The airplane was conceived when tensions with communist Eastern Europe reached levels approaching a full-blown crisis in the mid-1950s. U.S. military commanders desperately needed accurate assessments of Soviet worldwide military deployments, particularly near the Iron Curtain. Lockheed Aircraft Corporation’s subsonic U-2 (see NASM collection) reconnaissance aircraft was an able platform but the U. S. Air Force recognized that this relatively slow aircraft was already vulnerable to Soviet interceptors. They also understood that the rapid development of surface-to-air missile systems could put U-2 pilots at grave risk. The danger proved reality when a U-2 was shot down by a surface to air missile over the Soviet Union in 1960.

Lockheed’s first proposal for a new high speed, high altitude, reconnaissance aircraft, to be capable of avoiding interceptors and missiles, centered on a design propelled by liquid hydrogen. This proved to be impracticable because of considerable fuel consumption. Lockheed then reconfigured the design for conventional fuels. This was feasible and the Central Intelligence Agency (CIA), already flying the Lockheed U-2, issued a production contract for an aircraft designated the A-12. Lockheed’s clandestine ‘Skunk Works’ division (headed by the gifted design engineer Clarence L. "Kelly" Johnson) designed the A-12 to cruise at Mach 3.2 and fly well above 18,288 m (60,000 feet). To meet these challenging requirements, Lockheed engineers overcame many daunting technical challenges. Flying more than three times the speed of sound generates 316° C (600° F) temperatures on external aircraft surfaces, which are enough to melt conventional aluminum airframes. The design team chose to make the jet’s external skin of titanium alloy to which shielded the internal aluminum airframe. Two conventional, but very powerful, afterburning turbine engines propelled this remarkable aircraft. These power plants had to operate across a huge speed envelope in flight, from a takeoff speed of 334 kph (207 mph) to more than 3,540 kph (2,200 mph). To prevent supersonic shock waves from moving inside the engine intake causing flameouts, Johnson’s team had to design a complex air intake and bypass system for the engines.

Skunk Works engineers also optimized the A-12 cross-section design to exhibit a low radar profile. Lockheed hoped to achieve this by carefully shaping the airframe to reflect as little transmitted radar energy (radio waves) as possible, and by application of special paint designed to absorb, rather than reflect, those waves. This treatment became one of the first applications of stealth technology, but it never completely met the design goals.

Test pilot Lou Schalk flew the single-seat A-12 on April 24, 1962, after he became airborne accidentally during high-speed taxi trials. The airplane showed great promise but it needed considerable technical refinement before the CIA could fly the first operational sortie on May 31, 1967 – a surveillance flight over North Vietnam. A-12s, flown by CIA pilots, operated as part of the Air Force’s 1129th Special Activities Squadron under the "Oxcart" program. While Lockheed continued to refine the A-12, the U. S. Air Force ordered an interceptor version of the aircraft designated the YF-12A. The Skunk Works, however, proposed a "specific mission" version configured to conduct post-nuclear strike reconnaissance. This system evolved into the USAF’s familiar SR-71.

Lockheed built fifteen A-12s, including a special two-seat trainer version. Two A-12s were modified to carry a special reconnaissance drone, designated D-21. The modified A-12s were redesignated M-21s. These were designed to take off with the D-21 drone, powered by a Marquart ramjet engine mounted on a pylon between the rudders. The M-21 then hauled the drone aloft and launched it at speeds high enough to ignite the drone’s ramjet motor. Lockheed also built three YF-12As but this type never went into production. Two of the YF-12As crashed during testing. Only one survives and is on display at the USAF Museum in Dayton, Ohio. The aft section of one of the "written off" YF-12As which was later used along with an SR-71A static test airframe to manufacture the sole SR-71C trainer. One SR-71 was lent to NASA and designated YF-12C. Including the SR-71C and two SR-71B pilot trainers, Lockheed constructed thirty-two Blackbirds. The first SR-71 flew on December 22, 1964. Because of extreme operational costs, military strategists decided that the more capable USAF SR-71s should replace the CIA’s A-12s. These were retired in 1968 after only one year of operational missions, mostly over southeast Asia. The Air Force’s 1st Strategic Reconnaissance Squadron (part of the 9th Strategic Reconnaissance Wing) took over the missions, flying the SR-71 beginning in the spring of 1968.

After the Air Force began to operate the SR-71, it acquired the official name Blackbird– for the special black paint that covered the airplane. This paint was formulated to absorb radar signals, to radiate some of the tremendous airframe heat generated by air friction, and to camouflage the aircraft against the dark sky at high altitudes.

Experience gained from the A-12 program convinced the Air Force that flying the SR-71 safely required two crew members, a pilot and a Reconnaissance Systems Officer (RSO). The RSO operated with the wide array of monitoring and defensive systems installed on the airplane. This equipment included a sophisticated Electronic Counter Measures (ECM) system that could jam most acquisition and targeting radar. In addition to an array of advanced, high-resolution cameras, the aircraft could also carry equipment designed to record the strength, frequency, and wavelength of signals emitted by communications and sensor devices such as radar. The SR-71 was designed to fly deep into hostile territory, avoiding interception with its tremendous speed and high altitude. It could operate safely at a maximum speed of Mach 3.3 at an altitude more than sixteen miles, or 25,908 m (85,000 ft), above the earth. The crew had to wear pressure suits similar to those worn by astronauts. These suits were required to protect the crew in the event of sudden cabin pressure loss while at operating altitudes.

To climb and cruise at supersonic speeds, the Blackbird’s Pratt & Whitney J-58 engines were designed to operate continuously in afterburner. While this would appear to dictate high fuel flows, the Blackbird actually achieved its best "gas mileage," in terms of air nautical miles per pound of fuel burned, during the Mach 3+ cruise. A typical Blackbird reconnaissance flight might require several aerial refueling operations from an airborne tanker. Each time the SR-71 refueled, the crew had to descend to the tanker’s altitude, usually about 6,000 m to 9,000 m (20,000 to 30,000 ft), and slow the airplane to subsonic speeds. As velocity decreased, so did frictional heat. This cooling effect caused the aircraft’s skin panels to shrink considerably, and those covering the fuel tanks contracted so much that fuel leaked, forming a distinctive vapor trail as the tanker topped off the Blackbird. As soon as the tanks were filled, the jet’s crew disconnected from the tanker, relit the afterburners, and again climbed to high altitude.

Air Force pilots flew the SR-71 from Kadena AB, Japan, throughout its operational career but other bases hosted Blackbird operations, too. The 9th SRW occasionally deployed from Beale AFB, California, to other locations to carryout operational missions. Cuban missions were flown directly from Beale. The SR-71 did not begin to operate in Europe until 1974, and then only temporarily. In 1982, when the U.S. Air Force based two aircraft at Royal Air Force Base Mildenhall to fly monitoring mission in Eastern Europe.

When the SR-71 became operational, orbiting reconnaissance satellites had already replaced manned aircraft to gather intelligence from sites deep within Soviet territory. Satellites could not cover every geopolitical hotspot so the Blackbird remained a vital tool for global intelligence gathering. On many occasions, pilots and RSOs flying the SR-71 provided information that proved vital in formulating successful U. S. foreign policy. Blackbird crews provided important intelligence about the 1973 Yom Kippur War, the Israeli invasion of Lebanon and its aftermath, and pre- and post-strike imagery of the 1986 raid conducted by American air forces on Libya. In 1987, Kadena-based SR-71 crews flew a number of missions over the Persian Gulf, revealing Iranian Silkworm missile batteries that threatened commercial shipping and American escort vessels.

As the performance of space-based surveillance systems grew, along with the effectiveness of ground-based air defense networks, the Air Force started to lose enthusiasm for the expensive program and the 9th SRW ceased SR-71 operations in January 1990. Despite protests by military leaders, Congress revived the program in 1995. Continued wrangling over operating budgets, however, soon led to final termination. The National Aeronautics and Space Administration retained two SR-71As and the one SR-71B for high-speed research projects and flew these airplanes until 1999.

On March 6, 1990, the service career of one Lockheed SR-71A Blackbird ended with a record-setting flight. This special airplane bore Air Force serial number 64-17972. Lt. Col. Ed Yeilding and his RSO, Lieutenant Colonel Joseph Vida, flew this aircraft from Los Angeles to Washington D.C. in 1 hour, 4 minutes, and 20 seconds, averaging a speed of 3,418 kph (2,124 mph). At the conclusion of the flight, ‘972 landed at Dulles International Airport and taxied into the custody of the Smithsonian’s National Air and Space Museum. At that time, Lt. Col. Vida had logged 1,392.7 hours of flight time in Blackbirds, more than that of any other crewman.

This particular SR-71 was also flown by Tom Alison, a former National Air and Space Museum’s Chief of Collections Management. Flying with Detachment 1 at Kadena Air Force Base, Okinawa, Alison logged more than a dozen ‘972 operational sorties. The aircraft spent twenty-four years in active Air Force service and accrued a total of 2,801.1 hours of flight time.

Minox Contax Racetrack Playa

Racetrack Playa in Death Valley National Park.

For most of the year Racetrack Playa in Death Valley, California is a dry lake, a completely flat expanse of cracked white clay. There are a few scattered stones on the surface, from a handful of centimetres in diameter to half a metre. Some of the stones have trails hundreds of metres long displaying that they have moved across the ground – but how?

Nobody has noticed 1 in motion, but geologists have tracked the stones progress for years, usually in March.

The most likely explanation entails the spring weather. Rain and melting snow from the surrounding hills leaves a lot of of the rocks partly-submerged in enormous, shallow pools. As temperatures fall at evening, ice can form a collar around the base of a rock. This creates enough buoyancy for strong winds to overcome friction with the lake bed. This is only possible simply because of the flatness of the Playa, which allows wind to gust at 90 mph close to the ground.

In any case, the movement probably on lasts less than a minute and might only happen every many years. This is probably why the sailing stones of Racetrack Playa have remained a single of the world’s more elusive climate phenomena.

Quoting from Wikipedia | Space Shuttle Enterprise:

The Space Shuttle Enterprise (NASA Orbiter Vehicle Designation: OV-101) was the very first Space Shuttle orbiter. It was constructed for NASA as part of the Space Shuttle system to perform test flights in the atmosphere. It was constructed with out engines or a functional heat shield, and was for that reason not capable of spaceflight.

Initially, Enterprise had been intended to be refitted for orbital flight, which would have made it the second space shuttle to fly after Columbia. However, in the course of the building of Columbia, particulars of the final design changed, specifically with regard to the weight of the fuselage and wings. Refitting Enterprise for spaceflight would have involved dismantling the orbiter and returning the sections to subcontractors across the country. As this was an costly proposition, it was determined to be less expensive to construct Challenger about a body frame (STA-099) that had been created as a test article. Similarly, Enterprise was deemed for refit to replace Challenger soon after the latter was destroyed, but Endeavour was built from structural spares as an alternative.

Service

Construction started on the first orbiter on June 4, 1974. Designated OV-101, it was initially planned to be named Constitution and unveiled on Constitution Day, September 17, 1976. A create-in campaign by Trekkies to President Gerald Ford asked that the orbiter be named after the Starship Enterprise, featured on the tv show Star Trek. Even though Ford did not mention the campaign, the president—who for the duration of Planet War II had served on the aircraft carrier USS&nbspMonterey&nbsp(CVL-26) that served with USS&nbspEnterprise&nbsp(CV-6)—said that he was &quotpartial to the name&quot and overrode NASA officials.

The design of OV-101 was not the identical as that planned for OV-102, the 1st flight model the tail was constructed differently, and it did not have the interfaces to mount OMS pods. A huge quantity of subsystems—ranging from major engines to radar equipment—were not installed on this car, but the capacity to add them in the future was retained. Alternatively of a thermal protection system, its surface was mainly fiberglass.

In mid-1976, the orbiter was utilized for ground vibration tests, permitting engineers to examine information from an actual flight car with theoretical models.

On September 17, 1976, Enterprise was rolled out of Rockwell’s plant at Palmdale, California. In recognition of its fictional namesake, Star Trek creator Gene Roddenberry and most of the principal cast of the original series of Star Trek have been on hand at the dedication ceremony.

Approach and landing tests (ALT)

Main write-up: Method and Landing Tests

On January 31, 1977, it was taken by road to Dryden Flight Research Center at Edwards Air Force Base, to begin operational testing.

Even though at NASA Dryden, Enterprise was used by NASA for a assortment of ground and flight tests intended to validate aspects of the shuttle plan. The initial nine-month testing period was referred to by the acronym ALT, for &quotApproach and Landing Test&quot. These tests included a maiden &quotflight&quot on February 18, 1977 atop a Boeing 747 Shuttle Carrier Aircraft (SCA) to measure structural loads and ground handling and braking qualities of the mated program. Ground tests of all orbiter subsystems have been carried out to confirm functionality prior to atmospheric flight.

The mated Enterprise/SCA mixture was then subjected to five test flights with Enterprise unmanned and unactivated. The objective of these test flights was to measure the flight traits of the mated combination. These tests had been followed with 3 test flights with Enterprise manned to test the shuttle flight control systems.

Enterprise underwent 5 totally free flights exactly where the craft separated from the SCA and was landed beneath astronaut handle. These tests verified the flight characteristics of the orbiter design and were carried out below several aerodynamic and weight configurations. On the fifth and final glider flight, pilot-induced oscillation problems had been revealed, which had to be addressed just before the 1st orbital launch occurred.

On August 12, 1977, the space shuttle Enterprise flew on its own for the 1st time.

Preparation for STS-1

Following the ALT system, Enterprise was ferried amongst several NASA facilities to configure the craft for vibration testing. In June 1979, it was mated with an external tank and solid rocket boosters (recognized as a boilerplate configuration) and tested in a launch configuration at Kennedy Space Center Launch Pad 39A.

Retirement

With the completion of crucial testing, Enterprise was partially disassembled to allow specific elements to be reused in other shuttles, then underwent an international tour visiting France, Germany, Italy, the United Kingdom, Canada, and the U.S. states of California, Alabama, and Louisiana (for the duration of the 1984 Louisiana Planet Exposition). It was also utilised to fit-verify the in no way-utilized shuttle launch pad at Vandenberg AFB, California. Finally, on November 18, 1985, Enterprise was ferried to Washington, D.C., where it became property of the Smithsonian Institution.

Post-Challenger

Soon after the Challenger disaster, NASA deemed using Enterprise as a replacement. Nevertheless refitting the shuttle with all of the required gear needed for it to be employed in space was considered, but as an alternative it was decided to use spares constructed at the same time as Discovery and Atlantis to develop Endeavour.

Post-Columbia

In 2003, following the breakup of Columbia in the course of re-entry, the Columbia Accident Investigation Board performed tests at Southwest Analysis Institute, which employed an air gun to shoot foam blocks of equivalent size, mass and speed to that which struck Columbia at a test structure which mechanically replicated the orbiter wing leading edge. They removed a fiberglass panel from Enterprise’s wing to carry out analysis of the material and attached it to the test structure, then shot a foam block at it. Although the panel was not broken as a outcome of the test, the effect was sufficient to permanently deform a seal. As the reinforced carbon-carbon (RCC) panel on Columbia was 2.five occasions weaker, this recommended that the RCC top edge would have been shattered. Extra tests on the fiberglass were canceled in order not to risk damaging the test apparatus, and a panel from Discovery was tested to determine the effects of the foam on a similarly-aged RCC top edge. On July 7, 2003, a foam effect test designed a hole 41&nbspcm by 42.five&nbspcm (16.1&nbspinches by 16.7&nbspinches) in the protective RCC panel. The tests clearly demonstrated that a foam effect of the type Columbia sustained could seriously breach the protective RCC panels on the wing leading edge.

The board determined that the probable lead to of the accident was that the foam effect brought on a breach of a reinforced carbon-carbon panel along the leading edge of Columbia’s left wing, allowing hot gases generated for the duration of re-entry to enter the wing and cause structural collapse. This caused Columbia to spin out of control, breaking up with the loss of the entire crew.

Museum exhibit

Enterprise was stored at the Smithsonian’s hangar at Washington Dulles International Airport before it was restored and moved to the newly built Smithsonian’s National Air and Space Museum‘s Steven F. Udvar-Hazy Center at Dulles International Airport, where it has been the centerpiece of the space collection. On April 12, 2011, NASA announced that Space Shuttle Discovery, the most traveled orbiter in the fleet, will be added to the collection after the Shuttle fleet is retired. When that happens, Enterprise will be moved to the Intrepid Sea-Air-Space Museum in New York City, to a newly constructed hangar adjacent to the museum. In preparation for the anticipated relocation, engineers evaluated the car in early 2010 and determined that it was secure to fly on the Shuttle Carrier Aircraft when once more.

5_North and South over slavery
North and South over slavery and claimed rights to secede from the Union. The tempest raged back and forth over the county and the town for 1300 hundred days of pitiless strife and war before settling back into being a barren, alien landscape.

6_RD’s building
RD’s (“RD” henceforth for “Rezin Davis Shepherd”) building – beautiful as were all his buildings remains a Greek Revival style, with a two-story-portico and Corinthian flourishes. But in the 1860s, it would bear witness to all that was rent asunder and itself narrowly avoid destruction, unlike a less lucky altruistic juggernaut project of Shepherd’s in New Orleans – the palatial Almshouse. But this, RD’s Town Hall, first named, would eventually live a “long, happy life” first as the County Court, then into its present-day majesty as the signature building of Shepherd University.

Growing Up – RD Learns the Trade:

7_When he was just nine years old

When he was just nine years old, RD’s father, Abraham, placed him in the store and counting house in Baltimore of William Taylor,

9_an ambitious importer and ship-owner
an ambitious importer and ship-owner. RD’s incredible gifts surfaced when he – just eighteen – was sent to New Orleans to assure a good return on a huge shipment of British goods his firm had purchased for New Orleans’ customers. Then his first big “killing” was with another fresh-faced, hard-driving Taylor colleague, James McDonough. Wrote the Picayune: In October, 1803, it was well known throughout the country that Louisiana had been purchased by the United States. Mr. Taylor was the only merchant who seemed to comprehend the profit from one consequence of the this great political event.

10_in becoming a state
11_all sugar imports thereafter
12_cornered 1800 of those hogsheads
The firm realized that in becoming a state, a duty of 2.5 cents would be added to the price of all sugar imports thereafter. So Shepherd and McDonough – when all the sugar produced in the state was between 2100-2200 hogsheads – cornered 1800 of those hogsheads, giving young RD “a handsome capital for a young man to start in mercantile life.” He soon created a new firm shared with Taylor, then in time through age and retirement became RD’s alone.

13_Coming into his own
Coming into his own, he married Lucy Taylor Gorham of Barnstable, Massachusetts in 1808, who was “a niece and adopted daughter” of Taylor. On August 22nd, 1809, their only child, Ellen Shepherd, was born in Louisiana. (Lucy would die in 1814).

14_the penchant of RD
It was at this juncture the penchant of RD for regular, publicity-averse benefactions took root, in the moment of his willed defiance against a direct military order to work, instead, to save one particular wounded man, left for dead in war, a man who himself would live on to become the epitome of the proverbial Good Man, albeit

extraordinarily wealthy. His name was Judah Touro, a top-hatted, but humble Jewish businessman who believed in respect for all religions and daily applications of the code of good works. He was beloved throughout his circles and region as “the Israelite without guile.”

an old building in the rear of Jackson’s headquarters. Forgetting his orders, Mr. Shepherd went immediately to the place and found he was not dead, but, as the surgeon said, in a dying condition. Disregarding what the surgeon said, Shepherd got a cart, put him in it, administered stimulants, and took Touro to his own house. He then procured nurses, and by the closest attention, Mr. Touro’s life was saved. Mr. Shepherd returned late in the day,

having performed his mission, to find Commodore Patterson in a bad humor, and, speaking severely to him, the latter said: “Commodore, you can hang or shoot me, and it will be all right, but my best friend needed my assistance, and nothing on earth could have induced me to neglect him.”

RD’s businesses continued to grow exponentially and his brother, James Hervey Shepherd, was summoned from Shepherdstown to assist.

1839 – RD’s commissioned painting of the ship the “Ellen Brooks” is completed, attributed to Samuel Walters (British, 1811-1882), called “Ellen Brooks, Off Holyhead, Homeward Bound.”

1841 – RD buys 468 acres of land and begins building Wild Goose Farm, but not yet living there full-time; he also pays for most of the remodeling of the original Trinity Episcopal Church in Shepherdstown.

1842, June – RD signs a petition to Congress along with numerous other planters and sugar manufacturers in the state of Louisiana that asks for an increase in the duties on imported sugar.

1849 – RD places responsibilities on his eighteen-year-old nephew, Henry Shepherd Jr., who would become his agent in New Orleans through the Civil War, allowing RD to return more permanently to his Wild Goose Farm.

Although one account states Touro stipulated that RD free his enslaved persons, RD is shown to having owned numerous persons, enumerated in both the 1850 and 1860 Census slave schedules.

1854, January 6th – Touro’s Will makes Rezin Davis Shepherd residuary legatee of the estate and executor; 5,000 is willed to specific recipients. A sum iof ,000 is set aside for a palatial almshouse, with the added stipulation to RD that more sums, if needed, should be used to complete this priority project.

Judah Touro made out his will January 6, 1854 a few days before his death that said:

33_my dear, old, and devoted friend, Rezin Davis Shepherd
34_I hereby appoint and institute him
As regards my other designated executor, say my dear, old, and devoted friend, Rezin Davis Shepherd, to whom, under Divine Providence, I am greatly indebted for the preservation of my life when I was wounded on the 1st of January, 1815, I hereby appoint and institute him, the said Rezin Davis Shepherd, after payment of my particular legacies, and the debts of my succession, the universal legatee of the rest and residue of my estates, movable and immovable.

The Shepherd Family is Scattered By War:

37_The war hit the family hard
The war hit the family hard. Most of the young men enlisted in Virginia units. RD had to recalibrate his business strategies. Wrote the Richmond Daily Dispatch: June 8, 1861:
The New Orleans Delta states that R. D. Shepherd, Esq., who is now at an advanced time of life, living on his beautiful farm near Shepherdstown, Virginia, has directed his agent in New Orleans to pay over to the treasurer of the Confederate States a large sum of money, including, it is said, his whole annual income from rents in that city — the largest income enjoyed by any property holder — to be applied to the defence of the rights and the support of the independence of the South.

38_spring of 1862 when Federal General Banks
In the spring of 1862 when Federal General Banks with his army entered into Jefferson County, RD took refuge in Boston with his daughter.

39_As the war progressed
As the war progressed, its maw of destruction came closer to Shepherdstown’s nearly complete building. 130,000 troops moved in the area in September, 1862 for the bloody Maryland Campaign, just across the Potomac river. Wounded from the nearby battles poured into Shepherdstown, putting the unfinished Town Hall into service as an outdoor hospital.

Wrote Mary Bedinger Mitchell:

40_The unfinished Town Hall had stood in naked ugliness
The unfinished Town Hall had stood in naked ugliness for many a long day. Somebody threw a few rough boards across the beams, placed piles of straw over them, laid down single planks to walk upon, and lo, it was a hospital at once.

There were six churches and they were all full, the barn-like place known as the Drill Room, all the private houses after their capacity, the shops and empty buildings, the school-houses – every inch of space and yet the cry was for more room.

We went about our work with pale faces and trembling hands, yet trying to appear composed for the sake of our patients, who were much excited. We could hear the incessant explosions of artillery, the shrieking whistles of the shells, and the sharper, deadlier more thrilling roll of musketry; while every now and then the echo of some charging cheer would come, borne by the wind, and as the human voice would pierce that demoniacal clangor we would catch out breath and listen, and try not to sob, and turn back to the forlorn hospitals, to the suffering at our feet and before our eyes while imagination fainted at the thought of those other scenes hidden from us beyond the Potomac.

Had Federal General George McClellan crossed the Potomac and pursued General Lee’s scattered and mauled army, as historians have much criticized him since for not doing, Shepherdstown would have likely suffered greater damage, but, as it was, shells landed in the yards of the Lees and Morgans and one or two even hit Shepherd’s new Town Hall, but were of little consequence.

Property Losses in New Orleans:

41_RD’s fine residence at 18 Bourbon Street
42_18 Bourbon Street in New Orleans
More invasive, improvised use was being made of RD’s fine residence at 18 Bourbon Street in New Orleans, causing his nephew to formally appeal to the Federal powers-that-be in early 1864. He wrote:

43_From Brig. General James Bowen
January 29, 1864
From Brig. General James Bowen
Provost Marshal General
Department of the Gulf.

Sir:
The undersigned acting as the duly authorized agent and attorney in fact of Rezin Davis Shepherd, formerly the State of Virginia, but for more than eight months past residing with his daughter Mrs. Gorham Brooks in the city of Boston and State of Massachusetts, respectfully represents: That the said Shepherd is a loyal citizen of the United States and the true and lawful owner of the Brick Dwelling No. 18 Bourbon Street between Canal and Custom House Streets in the City of New Orleans and also of all the furniture and contents thereof: that in the month of June, 1862 Col. Stafford without show of authority, placed in possession of said house and contents, a man by the name of Horton or Houghton, who has ever since occupied and now occupied and uses the same as a Boarding House, and who never has paid any rent or compensation there and continually refused to do so.

Under the circumstances, the undersigned respectfully appeals to you, General, for relief, and asks that the matter be referred to Capt. Edward Page and Thomas Tileston, or other of them for investigation and that the aforesaid premises and contents be restored to the possession of the owner without delay; Henry Shepherd Jr.

Like The Town Hall, the huge, magnificent Almshouse in New Orleans remained unfinished, to be hit by a worse fate. Shepherd was charged by Touro’s will to first put ,00 toward its construction, then be prepared to put more money into its construction- including even some of Shepherd’s own funds – as recipient of Touro’s residue.

44_occupied by detachments of the 2nd Maine Cavalry
45_The fire started
46_Baked beans fired the building
On September 1, 1865, at a time the Almshouse in New Orleans – still with an unfinished, floorless top floor – was occupied by detachments of the 2nd Maine Cavalry and Company K, First Louisiana Cavalry. A baking oven was in heavy use at one end of the building so that heat would be carried through a fissure in a ventilation system close by. The fire started in the rafters above the third floor. It was night-time with a high wind and no flooring yet laid for the third floor in that wing. Coals dripping from the fire then ignited tar on the lower walls. “Baked beans fired the building” said one from the 2nd Maine Cavalry. The building was uninsured. Just a few months later R. D. Shepherd died of typhoid fever, November 10, 1865, no longer the executor of the estate, leaving no philanthropist to help make up the loss.

Wrote the editors of the Times-Picayune in a long obituary:
In his native village he erected a splendid building, designed for a town hall, also a large academy, with beautiful grounds and a walk. He also deposited with the Mayor annually a large sum to buy fuel and provisions for the poor. He also erected the largest and most costly church in Jefferson County. Many other acts of public and private benevolence were performed by him in his quiet, furtive manner.

With war ended and when he was still healthy, RD had urged that his Town Hall become the County Court since the Charlestown courthouse was a battle-scarred ruin, especially from a shelling it took in the fall of 1863.

A Visitor Contemplates Charlestown’s Ruined Courthouse in mid-1865:

47_the court-house, where that mockery of justice was performed, was a ruin
48_Four massive white brick pillars, still standing, supported a riddled roof
A short walk up into the centre of the town took us to the scene of John Brown’s trial. It was a consolation to see that the jail had been laid in ashes, and that the court-house, where that mockery of justice was performed, was a ruin abandoned to rats and toads. Four massive white brick pillars, still standing, supported a riddled roof, through which God’s blue sky and gracious sunshine smiled. The main portion of the building had been literally torn to pieces. In the floor-less hall of justice rank weeds were growing.

49_Names of Union soldiers were scrawled along the walls
Names of Union soldiers were scrawled along the walls. No torch had been applied to the wood-work, but the work of destruction had been performed by the hands of hilarious soldier-boys ripping up floors and pulling down laths and joists to the tune of “John Brown,” the swelling melody of the song, and the accompaniment of crashing partitions, reminding the citizens, who thought to have destroyed the old hero, that his soul was marching on. It was also a consolation to know that the court-house and jail would probably never be rebuilt, the county-seat having been removed from Charlestown to Shepherdstown — “forever,” say the resolute loyal citizens of Jefferson County, who rose to vote it back again.

While RD’s nephew and agent, Henry Shepherd Jr. was in New Orleans during the war, minding the family interests, three of his brothers were at war. The eldest Rezin Davis, his older brother who had a young family

52_eldest Rezin Davis, his older brother who had a young family
since 1858, died of disease November 2, 1862 at his “river cottage” after imprisonment in the Old Capitol Prison for being an associate of Confederate spy, Redmond Burke. He left his widow, Elizabeth Boteler Stockton Shepherd, two children (Fannie and Alexandria) and a third (David) on the way. Probably first buried on his farm, Rezin Shepherd (a nephew of the patriarch) was reburied after peace came in the new Elmwood Cemetery. His site was joined by all his family as time unspooled.

53_twenty-five year-old Abraham
Henry Jr.’s next brother, twenty-five year-old Abraham, enlisted May 22nd, 1861, would move over to Co. F. of the 17th Virginia Cavalry, get wounded at the third battle of Winchester in September 19, 1864, and become a prisoner of war. But he survived the war and died many years later in 1907.

54_Henry Jr.’s younger brother, James Touro (Truro) Shepherd
Henry Jr.’s younger brother, James Touro (Truro) Shepherd, enlisted as a Private May 1st, 1861 in the 2nd Virginia Infantry. Like many, the rigors of marching under Gen. Stonewall Jackson proved an impetus to transfer out into a Cavalry regiment, and he joined Co. B of Gen. Stuart’s Horse Artillery under John Pelham, with a promotion to first lieutenant. His service record ends abruptly in the spring of 1862. The Shepherdstown Register in September, 1865 reported him having died in “Richmond City” in March, 1862. His marker dates his death as August 13, 1862, which may be the date of his re-internment into the family burial ground.

Two sons of James H. and his wife, Florence Hamtramck Shepherd were buried a few feet apart in the family burial ground on Shepherdstown’s New Street adjacent to the Episcopal rectory. Robert F. Shepherd, who joined Co. H, 2nd Va. Infantry, died May 4, 1862 of pneumonia.

Rezin Davis Shepherd was buried there too, in his own time.

He left all his fortune to his daughter, who, since 1855, had been a widow.

Wrote the Shepherdstown Register: A Large Estate – the late Rezin D. Shepherd left an estate valued at about ,500,000 all of which goes to his daughter, Mrs. Brooks of Boston. He was born in 1784 (on the lot where the court house would be built). In 1809 he went to New Orleans and engaged in the commission business until 1849 and was the executor of the estate of the late Judah Touro. Mr. Shepherd was formerly a merchant in this city, residing on High Street. He accumulated a very large property in New Orleans and was reputed to be one of the wealthiest men of that city. Upon the breaking out of the rebellion, he returned to Boston and resided for a short time with his daughter and sole heir, Mrs. Gorham Brooks, widow of a son of the late Peter C. Brooks. His estate on High Street was formerly, we believe the property of Samuel Dexter.

The Massachusetts Historical Society today displays a cannon donated by the family and acquired by RD – a smaller version of the one that so severely wounded RD’s friend, Judah Touro.

The visiting journalist Trowbridge was proven wrong – the county seat DID go back to the Charlestown Courthouse. Wrote the editors of the Charlestown-based newspaper, The Spirit of Jefferson, in 1894:

58_The Normal College building, formerly the town hall
The Normal College building, formerly the town hall, on Main Street, is a handsome structure, the gift of one of the Shepherd family, Rezin D. from which the town takes its name. You will remember that it was used as a court house since the war and the courts of Jefferson county were held there, one Judge Hall sitting on the bench. A political rape was perpetuated on Charlestown, the party in power, fitly termed radicals, thought they had a sure thing of it, built a jail and added a wing to either side of the town hall, but “the best laid schemes of mice and men gang af’t aglee.” The fellows that did all this mischief were turned down by the people and things took their normal shape and Charlestown was again the county seat.

Shepherd University began when the county seat of Jefferson County, West Virginia, was moved from Shepherdstown to Charles Town in July 1871. On February 27, 1872, the Legislature of West Virginia passed the following act: “That a branch of the State Normal School be and the same is hereby established at the building known as Shepherd College, in Shepherdstown, in the county of Jefferson.”

59_RD’s descendant, Shepherd Brooks
RD’s descendant, Shepherd Brooks, made it final when he deeded the property and building over to the School and a three-person board of trustees to maintain it.

As they say, settings reverse, the tide of life had gone out – and – came back in again.

Details, quoting from Smithsonian National Air and Space Museum | Curtiss P-40E Warhawk (Kittyhawk IA):

Whether known as the Warhawk, Tomahawk, or Kittyhawk, the Curtiss P-40 proved to be a successful, versatile fighter during the first half of World War II. The shark-mouthed Tomahawks that Gen. Claire Chennault’s "Flying Tigers" flew in China against the Japanese remain among the most popular airplanes of the war. P-40E pilot Lt. Boyd D. Wagner became the first American ace of World War II when he shot down six Japanese aircraft in the Philippines in mid-December 1941.

Curtiss-Wright built this airplane as Model 87-A3 and delivered it to Canada as a Kittyhawk I in 1941. It served until 1946 in No. 111 Squadron, Royal Canadian Air Force. U.S. Air Force personnel at Andrews Air Force Base restored it in 1975 to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Long Description:
Whether it was the Tomahawk, Warhawk, or Kittyhawk, the Curtiss P-40 was a successful and versatile fighter aircraft during the first half of World War II. The shark-mouthed Tomahawks that General Claire Chennault led against the Japanese remain among the most popular airplanes of the war. In the Phillipines, Lt. Boyd D. Wagner became the first American ace of World War II while flying a P-40E when he shot down six Japanese aircraft during mid-December 1941. P-40s were first-line Army Air Corps fighters at the start of the war but they soon gave way to more advanced designs such as the Republic P-47 Thunderbolt and the Lockheed P-38 Lightning (see NASM collection for both aircraft). The P-40 is not ranked among the best overall fighters of the war but it was a rugged, effective design available in large numbers early in the war when America and her allies urgently required them. The P-40 remained in production from 1939 to the end of 1944 and a total of 13, 737 were built.

Design engineer Dr. Donovan R. Berlin layed the foundation for the P-40 in 1935 when he designed the agile, but lightly-armed, P-36 fighter equipped with a radial, air-cooled engine. The Curtiss-Wright Corporation won a production contract for 210 P-36 airplanes in 1937-the largest Army airplane contract awarded since World War I. Worldwide, fighter aircraft designs matured rapidly during the late 1930s and it was soon obvious that the P-36 was no match for newer European designs. High altitude performance in particular became a priceless commodity. Berlin attempted to improve the P-36 by redesigning it in to accommodate a turbo-supercharged Allison V-1710-11 inline, liquid-cooled engine. The new aircraft was designated the XP-37 but proved unpopular with pilots. The turbo-supercharger was not reliable and Berlin had placed the cockpit too far back on the fuselage, restricting the view to the front of the fighter. Nonetheless, when the engine was not giving trouble, the more-streamlined XP-37 was much faster than the P-36.

Curtiss tried again in 1938. Berlin had modified another P-36 with a new Allison V-1710-19 engine. It was designated the XP-40 and first flew on October 14, 1938. The XP-40 looked promising and Curtiss offered it to Army Air Corps leaders who evaluated the airplane at Wright Field, Ohio, in 1939, along with several other fighter proposals. The P-40 won the competition, after some modifications, and Curtiss received an order for 540. At this time, the armament package consisted of two .50 caliber machine guns in the fuselage and four .30 caliber machine guns in the wings.

After production began in March 1940, France ordered 140 P-40s but the British took delivery of these airplanes when Paris surrendered. The British named the aircraft Tomahawks but found they performed poorly in high-altitude combat over northern Europe and relegated them to low-altitude operations in North Africa. The Russians bought more than 2,000 P-40s but details of their operational history remain obscure.

When the United States declared war, P-40s equipped many of the Army Air Corps’s front line fighter units. The plucky fighter eventually saw combat in almost every theater of operations being the most effective in the China-Burma-India (CBI) Theater. Of all the CBI groups that gained the most notoriety of the entire war, and remains to this day synonymous with the P-40, is the American Volunteer Group (AVG) or the Flying Tigers. The unit was organized after the Chinese gave former U. S. Army Air Corps Captain Claire Lee Chennault almost 9 million dollars in 1940 to buy aircraft and recruit pilots to fly against the Japanese. Chennault’s most important support within the Chinese government came from Madam Chiang Kai-shek, a Lt. Colonel in the Chinese Air Force and for a time, the service’s overall commander.

The money from China diverted an order placed by the British Royal Air Force for 100 Curtiss-Wright P-40B Tomahawks but buying airplanes was only one important step in creating a fighting air unit. Trained pilots were needed, and quickly, as tensions across the Pacific escalated. On April 15, 1941, President Franklin D. Roosevelt quietly signed an Executive Order permitting Chennault to recruit directly from the ranks of American military reserve pilots. Within a few months, 350 flyers joined from pursuit (fighter), bomber, and patrol squadrons. In all, about half the pilots in the Flying Tigers came from the U. S. Navy and Marine Corps while the Army Air Corps supplied one-third. Factory test pilots at Bell, Consolidated, and other companies, and commercial airline pilots, filled the remaining slots.

The Flying Tigers flew their first mission on December 20. The unit’s name was derived from the ferocious fangs and teeth painted on the nose of AVG P-40s at either side of the distinctive, large radiator air intake. The idea is said to originate from pictures in a magazine that showed Royal Air Force Tomahawks of No. 112 Squadron, operating in the western desert of North Africa, adorned with fangs and teeth painted around their air intakes. The Flying Tigers were the first real opposition the Japanese military encountered. In less than 7 months of action, AVG pilots destroyed about 115 Japanese aircraft and lost only 11 planes in air-to-air combat. The AVG disbanded on July 4, 1942, and its assets, including a few pilots, became a part of the U. S. Army Air Forces (AAF) 23rd Fighter Group in the newly activated 14th Air Force. Chennault, now a Brigadier General, assumed command of the 14th AF and by war’s end, the 23rd was one of the highest-scoring Army fighter groups.

As wartime experience in the P-40 mounted, Curtiss made many modifications. Engineers added armor plate, better self-sealing fuel tanks, and more powerful engines. They modified the cockpit to improve visibility and changed the armament package to six, wing-mounted, .50 caliber machine guns. The P-40E Kittyhawk was the first model with this gun package and it entered service in time to serve in the AVG. The last model produced in quantity was the P-40N, the lightest P-40 built in quantity, and much faster than previous models. Curtiss built a single P-40Q. It was the fastest P-40 to fly (679 kph/422 mph) but it could not match the performance of the P-47 Thunderbolt and the P-51 Mustang so Curtiss ended development of the P-40 series with this model. In addition to the AAF, many Allied nations bought and flew P-40s including England, France, China, Russia, Australia, New Zealand, Canada, South Africa, and Turkey.

The Smithsonian P-40E did not serve in the U. S. military. Curtiss-Wright built it in Buffalo, New York, as Model 87-A3 and delivered it to Canada as a Kittyhawk IA on March 11, 1941. It served in No. 111 Squadron, Royal Canadian Air Force (RCAF). When the Japanese navy moved to attack Midway, they sent a diversionary battle group to menace the Aleutian Islands. Canada moved No. 111 Squadron to Alaska to help defend the region. After the Japanese threat diminished, the unit returned to Canada and eventually transferred to England without its P-40s. The RCAF declared the NASM Kittyhawk IA surplus on July 27, 1946, and the aircraft eventually returned to the United States. It had several owners before ending up with the Explorer Scouts youth group in Meridian, Mississippi. During the early 1960s, the Smithsonian began searching for a P-40 with a documented history of service in the AVG but found none. In 1964, the Exchange Club in Meridian donated the Kittyhawk IA to the National Aeronautical Collection, in memory of Mr. Kellis Forbes, a local man devoted to Boys Club activities. A U. S. Air Force Reserve crew airlifted the fighter to Andrews Air Force Base, Maryland, on March 13, 1964. Andrews personnel restored the airplane in 1975 and painted it to represent an aircraft of the 75th Fighter Squadron, 23rd Fighter Group, 14th Air Force.

Quoting from Wikipedia | Curtiss P-40 Warhawk:

The Curtiss P-40 Warhawk was an American single-engine, single-seat, all-metal fighter and ground attack aircraft that first flew in 1938. It was used by the air forces of 28 nations, including those of most Allied powers during World War II, and remained in front line service until the end of the war. It was the third most-produced American fighter, after the P-51 and P-47; by November 1944, when production of the P-40 ceased, 13,738 had been built, all at Curtiss-Wright Corporation‘s main production facility at Buffalo, New York.

The P-40 design was a modification of the previous Curtiss P-36; this reduced development time and enabled a rapid entry into production and operational service.

Warhawk was the name the United States Army Air Corps adopted for all models, making it the official name in the United States for all P-40s. The British Commonwealth and Soviet air forces used the name Tomahawk for models equivalent to the P-40B and P-40C, and the name Kittyhawk for models equivalent to the P-40D and all later variants.

The P-40’s lack of a two-stage supercharger made it inferior to Luftwaffe fighters such as the Messerschmitt Bf 109 or the Focke-Wulf Fw 190 in high-altitude combat and it was rarely used in operations in Northwest Europe. Between 1941 and 1944, however, the P-40 played a critical role with Allied air forces in three major theaters: North Africa, the Southwest Pacific and China. It also had a significant role in the Middle East, Southeast Asia, Eastern Europe, Alaska and Italy. The P-40’s performance at high altitudes was not as critical in those theaters, where it served as an air superiority fighter, bomber escort and fighter bomber.

P-40s first saw combat with the British Commonwealth squadrons of the Desert Air Force (DAF) in the Middle East and North African campaigns, during June 1941. The Royal Air Force‘s No. 112 Squadron was among the first to operate Tomahawks, in North Africa, and the unit was the first to feature the "shark mouth" logo, copying similar markings on some Luftwaffe Messerschmitt Bf 110 twin-engine fighters.

Although it gained a post-war reputation as a mediocre design, suitable only for close air support, more recent research including scrutiny of the records of individual Allied squadrons indicates that the P-40 performed surprisingly well as an air superiority fighter, at times suffering severe losses, but also taking a very heavy toll on enemy aircraft. The P-40 offered the additional advantage of low cost, which kept it in production as a ground-attack fighter long after it was obsolete in the air superiority role.

As of 2008, 19 P-40s were airworthy.

Details, quoting from Smithsonian National Air and Space Museum | Space Shuttle Enterprise:

Manufacturer:
Rockwell International Corporation

Country of Origin:
United States of America

Dimensions:
Overall: 57 ft. tall x 122 ft. long x 78 ft. wing span, 150,000 lb.
(1737.36 x 3718.57 x 2377.44cm, 68039.6kg)

Materials:
Aluminum airframe and body with some fiberglass features; payload bay doors are graphite epoxy composite; thermal tiles are simulated (polyurethane foam) except for test samples of actual tiles and thermal blankets.

The first Space Shuttle orbiter, "Enterprise," is a full-scale test vehicle used for flights in the atmosphere and tests on the ground; it is not equipped for spaceflight. Although the airframe and flight control elements are like those of the Shuttles flown in space, this vehicle has no propulsion system and only simulated thermal tiles because these features were not needed for atmospheric and ground tests. "Enterprise" was rolled out at Rockwell International’s assembly facility in Palmdale, California, in 1976. In 1977, it entered service for a nine-month-long approach-and-landing test flight program. Thereafter it was used for vibration tests and fit checks at NASA centers, and it also appeared in the 1983 Paris Air Show and the 1984 World’s Fair in New Orleans. In 1985, NASA transferred "Enterprise" to the Smithsonian Institution’s National Air and Space Museum.
