Kosmos 285 ( Russian: Космос 285 meaning Cosmos 285), known before launch as DS-P1-Yu No.24, [1] was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles. It was a 250-kilogram (550 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and launched in 1969 as part of the Dnepropetrovsk Sputnik programme. [2]
Kosmos 285 was launched from Site 133/1 at the Plesetsk Cosmodrome, [1] atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 3 June 1969 at 12:57:27 UTC, and resulted in Kosmos 285's successful deployment into low Earth orbit. [3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1969-049A.
Kosmos 285 was operated in an orbit with a perigee of 257 kilometres (160 mi), an apogee of 452 kilometres (281 mi), 71 degrees of inclination, and an orbital period of 91.6 minutes. [2] [4] It remained in orbit until it decayed and reentered the atmosphere on 7 October 1969. [4] It was the twenty-second of seventy nine DS-P1-Yu satellites to be launched, [2] and the twenty-first of seventy two to successfully reach orbit. [5]
