63rd and last flight of Atlas IIAS. 576th and final launch of Rocketdyne-powered Atlas rockets. Final launch from LC36A after 42 years of use. Launch delayed from June 24 and 25, July 1 and 27, August 27, 28, 29 and 30. The payload was probably a communications satellite used to relay data from imaging spy satellites.
Atlas II was a member of the Atlas family of launch vehicles, which evolved from the successful Atlas missile program of the 1950s. It was designed to launch payloads into low earth orbit, geosynchronous transfer orbit or geosynchronous orbit. Sixty-three launches of the Atlas II, IIA and IIAS models were carried out between 1991 and 2004; all sixty-three launches were successes, making the Atlas II the most reliable launch system in history.
Lockheed Martin's Space Division started in the production of missiles and later ICBM's in the 1950s. Their TITAN missile system was used for 12 Gemini spacecraft and the Voyager probes. They have worked largely in collaboration with NASA on many of their probes, landers, and spacecraft, and hope to play a key role in NASA's return to the moon in 2024.
