Summary
US-KS 3 launched on a Soviet Space Program Proton-K/DM from 200/39 (200L), Baikonur Cosmodrome, Republic of Kazakhstan on February 21, 1985. It was Soviet Space Program's 1,868th launch, 12th this year and humanity's 2,920th orbital launch attempt. It was the 51st Proton-K/DM flight and the 2nd this year. The payload was bound for Geostationary Orbit (Direct-GEO). Kosmos-1629, one of 6 catalogued objects, reached a 36,064 × 36,151 km orbit inclined 1.3°. 6 objects from this launch are catalogued, one of them a payload.
