This image shows the assembled telescope in the clean room prior to launch. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/213572main_Observatory_lg/213572main_Observatory_lg.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Chandra/Chandra.dc.xml Named in honor of the Nobel-prize winning Indian-American astrophysicist Subrahmanyan Chandrasekhar, the Chandra X-ray Observatory is the world’s most powerful X-ray telescope. It has eight-times greater resolution and can detect sources more than 20-times fainter than any previous X-ray telescope. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Chandra/Chandra.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/KAOflight/KAOflight.dc.xml For over twenty years, the Kuiper Airborne Observatory (KAO) was operated as the world's only airborne telescope devoted exclusively to astronomical research. KAO was named after the astronomer Gerard P. Kuiper. Carrying a 36-inch reflecting telescope, KAO was a converted C-141 military cargo plane with a 160-foot wingspan. Flying at altitudes of 41,000 to 45,000 feet, above 99 percent of the Earth's infrared-absorbing water vapor, KAO was capable of conducting infrared astronomy. Harvey would have observed from behind the telescope; the telescope was looking out the hole in the roof behind the cockpit. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/KAOflight/KAOflight.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-COBE/NASA-COBE.dc.xml In 1989, the Cosmic Background Explorer (CoBE) spacecraft was launched into an Earth orbit to make a full sky map of the Cosmic Microwave Background (CMB) radiation. CoBE found very subtle irregularities in the otherwise very uniform CMB, findings that are considered important evidence in support of the Big Bang theory. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/NASA-COBE/NASA-COBE.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/OAO_NASA/OAO_NASA.dc.xml OAO-3 was launched on August 21, 1972. It carried an X-ray detector built by University College of London's Mullard Space Science Laboratory and an 80-cm UV telescope built by Princeton University. After its launch, it was named Copernicus to mark the 500th anniversary of the birth of Nicolaus Copernicus. Copernicus operated until February 1981, and returned high resolution spectra of hundreds of stars along with extensive X-ray observations. This picture shows OAO-3 in the clean room at Kennedy Space Center. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/OAO_NASA/OAO_NASA.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/OSO-Ball-Aerospace/OSO-Ball-Aerospace.dc.xml The objectives of the Orbiting Solar Observatory (OSO) satellite series were to perform solar physics experiments above the atmosphere during a complete solar cycle and to map the celestial sphere for direction and intensity of UV light, X-rays, and gamma radiation. The OSO-1, built by Ball Aerospace, was the first satellite to have pointed instruments and onboard tape recorders for data storage. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/OSO-Ball-Aerospace/OSO-Ball-Aerospace.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Sputnik_Satellite/Sputnik_Satellite.dc.xml The Sputnik 1 satellite, shown here on a rigging truck in the assembly shop, was successfully launched and entered Earth's orbit on October 4, 1957. Sputnik shocked the world, giving the Soviet Union the distinction of sending the first human-made object into space and placing the United States a step behind in the space race. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Sputnik_Satellite/Sputnik_Satellite.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/heao2_prepflight/heao2_prepflight.dc.xml Einstein Observatory (HEAO-2) was the first fully imaging X-ray telescope put into space and the second of NASA's three High Energy Astrophysical Observatories. Named HEAO-B before launch, the observatory's name was changed to honor Albert Einstein upon its successfully attaining orbit. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/heao2_prepflight/heao2_prepflight.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/vanguard1_from_NRL/vanguard1_from_NRL.dc.xml Between 1955 and 1959, NRL conducted the first American satellite program, named Project Vanguard. On March 17, 1958, the Vanguard I satellite was successfully launched into Earth orbit. Just 6 inches (152 mm) in diameter and weighing 3 pounds (1.4 kg), Vanguard 1 was described by then-Soviet Premier Nikita Khrushchev as, "The grapefruit satellite." Here NRL scientists from the Vanguard I team mount the satellite in the rocket. Vanguard 1 is the oldest artificial satellite still in space, as its predecessors, Sputnik 1, Sputnik 2, and Explorer 1, have fallen out of orbit. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/vanguard1_from_NRL/vanguard1_from_NRL.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/vela5b_2/vela5b_2.dc.xml The Vela satellites are stacked one on top of the other in a clean room prior to the launch.
