Kosmos 909 (Russian: Космос 909 meaning Cosmos 909) was a satellite which was used as a target for tests of anti-satellite weapons. It was launched by the Soviet Union in 1977 as part of the Dnepropetrovsk Sputnik programme,[1] and used as a target for Kosmos 910 and Kosmos 918, as part of the Istrebitel Sputnikov programme.[2]

It was launched aboard a Kosmos-3M carrier rocket,[3] from Site 132/2 at the Plesetsk Cosmodrome. The launch occurred at 16:30 UTC on 19 May 1977.[4]

Kosmos 909 was placed into a low Earth orbit with a perigee of 985 kilometres (612 mi), an apogee of 2,111 kilometres (1,312 mi), 65.9 degrees of inclination, and an orbital period of 117 minutes.[1] Attempted interceptions by Kosmos 910 and 918 on 23 May and 17 June respectively failed, and as of 2009 Kosmos 909 remains in orbit.[2][5]

Kosmos 909 was the fifth of ten Lira satellites to be launched,[1] of which all but the first were successful. Lira was derived from the earlier DS-P1-M satellite, which it replaced.
