Kosmos 1285 was launched from
international designator 1981-071A.[4] The United States Space Command assigned it the Satellite Catalog Number 12627.[4]
Kosmos 1285 was a US-K satellite like Kosmos 862 that self-destructed in orbit, NASA believe deliberately. 1285 was placed in a temporary transfer orbit on the day of launch by its launch vehicle but never maneuvered to an operational orbit. This suggests an early fatal spacecraft malfunction.[5] All of its trackable debris is still in orbit.[6]
