Summary
Potok 4 launched on a Soviet Space Program Proton K/DM-2 from 200/39 (200L), Baikonur Cosmodrome, Republic of Kazakhstan on October 1, 1987. It was Soviet Space Program's 2,124th launch, 74th this year and humanity's 3,227th orbital launch attempt. It was the 15th Proton K/DM-2 flight and the 4th this year. The payload was bound for Geostationary Orbit (Direct-GEO). Kosmos-1888, one of 6 catalogued objects, reached a 35,736 × 35,964 km orbit inclined 0.9°. 6 objects from this launch are catalogued, one of them a payload.
