Dr. Townsend, who was the Project Manager of the Small Astronomy Satellite Program, named the satellite Uhuru, which means freedom in Swahili. Uhuru would go on to detect evidence of black holes, neutron stars, and vast expanses of hot gas in systems containing thousands of galaxies. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/484px-X-Ray_Explorer_Satellite_wikipedia/484px-X-Ray_Explorer_Satellite_wikipedia.dc.xml Wed, 02 Dec 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/GiacconiUhuruSatellite1970/GiacconiUhuruSatellite1970.dc.xml Riccardo Giacconi stands with the Uhuru satellite, circa 1970. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/GiacconiUhuruSatellite1970/GiacconiUhuruSatellite1970.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Horsehead-Nebula-1902/Horsehead-Nebula-1902.dc.xml The Horsehead nebula is a dark interstellar cloud of dust and non-luminous gas situated 1,600 light years away in the direction of constellation Orion. This photographic image was made on January 25, 1900 by Isaac Roberts (1829-1904), an amateur astronomer. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Horsehead-Nebula-1902/Horsehead-Nebula-1902.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Occhialini/Occhialini.dc.xml The Italian-Dutch Satellite for X-ray astronomy, Beppo-Sax, was named for Giuseppe Occhialini. The satellite played a crucial role in resolving the origin of gamma-ray bursts (GRBs). http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Occhialini/Occhialini.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Rossi-and-Multiplate-Mirror/Rossi-and-Multiplate-Mirror.dc.xml Bruno Rossi standing before the multiplate cloud chamber used by his Cosmic Ray Group at MIT, 1954. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/Rossi-and-Multiplate-Mirror/Rossi-and-Multiplate-Mirror.dc.xml Thu, 01 Jan 1970 12:00:00 GMT http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/V-2-rocket-at-White-Sands/V-2-rocket-at-White-Sands.dc.xml As the Army set to work with V-2 rockets at the White Sands Missile Range in New Mexico, scientific users were invited to fill the space of the 2000-pound warhead with instruments. E.O. Hulburt at the Naval Research Laboratory (NRL) Optics Division jumped at the chance. Between 1946 and 1951, the NRL undertook 80 experiments using V-2 rockets that provided new and valuable information about the nature of Earth's upper atmosphere and ionosphere. The first launch, on October 10, 1946, delivered the first recorded solar spectrum of the Sun from above Earth's atmosphere. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/V-2-rocket-at-White-Sands/V-2-rocket-at-White-Sands.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/uhuruLaunch-72/uhuruLaunch-72.dc.xml Awaiting launch from the San Marco Platform in Kenya, Uhuru was the first satellite specifically for the purpose of X-ray astronomy. It was also known as the X-ray Explorer Satellite SAS-A, for Small Astronomy Satellite A, being first of the three-spacecraft SAS series. http://ecuip-xtf.lib.uchicago.edu/xtf/view?docId=grxr/uhuruLaunch-72/uhuruLaunch-72.dc.xml Thu, 01 Jan 1970 12:00:00 GMT
