Summary
US-KS 2 launched on a Soviet Space Program Proton-K/DM from 200/40, Baikonur Cosmodrome, Republic of Kazakhstan on March 29, 1984. It was Soviet Space Program's 1,782nd launch, 23rd this year and humanity's 2,806th orbital launch attempt. It was the 45th Proton-K/DM flight and the 4th this year. The payload was bound for Geostationary Orbit (Direct-GEO). Kosmos-1546, one of 6 catalogued objects, reached a 36,076 × 36,118 km orbit inclined 1.3°. 6 objects from this launch are catalogued, one of them a payload.
