Associated space launch
The satellite Kosmos 2285 was an experimental earth observation satellite. It was reportedly a prototype for the planned Obzor series of earth observation satellites, which was eventually not developed.
SL-8 R/B was lifted into orbit during the mission ‘Kosmos-3M | Obzor Test’, on board a Kosmos-3M space rocket.
The launch took place on Aug. 2, 1994, 8 p.m. from 132/1 (132L).
