197640798Washington DC: GPO 1976. Presumed First Edition/First Printing. Wraps. good. xi 1 231 1 pages. Wraps. Frontis illustration. Illustrations. Acronyms. Author index. Pencil erasure on half-title. This volume contains the author's summaries of their papers on the space telescope presented at the 21st annual meeting of the American Astronautical Society at Denver Colorado August 26-28 1975. Space-based astronomy had begun on a very small scale following World War II as scientists made use of developments that had taken place in rocket technology. The first ultraviolet spectrum of the Sun was obtained in 194612 and the National Aeronautics and Space Administration NASA launched the Orbiting Solar Observatory OSO to obtain UV X-ray and gamma-ray spectra in 1962. An orbiting solar telescope was launched in 1962 by the United Kingdom as part of the Ariel space program and in 1966 NASA launched the first Orbiting Astronomical Observatory OAO mission. OAO-1's battery failed after three days terminating the mission. It was followed by OAO-2 which carried out ultraviolet observations of stars and galaxies from its launch in 1968 until 1972 well beyond its original planned lifetime of one year. The OSO and OAO missions demonstrated the important role space-based observations could play in astronomy and in 1968 NASA developed firm plans for a space-based reflecting telescope with a mirror 3 m in diameter known provisionally as the Large Orbiting Telescope or Large Space Telescope LST with a launch slated for 1979. These plans emphasized the need for manned maintenance missions to the telescope to ensure such a costly program had a lengthy working life and the concurrent development of plans for the reusable space shuttle indicated that the technology to allow this was soon to become available.
