Summary
Copernicus launched on an United States Air Force Atlas SLV-3C Centaur from Launch Complex 36B, Cape Canaveral SFS, FL, USA on August 21, 1972. It was United States Air Force's 580th launch, 16th this year and humanity's 1,377th orbital launch attempt. It was the 17th Atlas SLV-3C Centaur flight and the 4th this year. The payload was bound for low Earth orbit (LEO). Copernicus, one of 3 catalogued objects, reached a 802 × 804 km orbit inclined 34.9°. 3 objects from this launch are catalogued, one of them a payload.
