Kosmos 967 (Russian: Космос 967 meaning Cosmos 967) is 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 970 and Kosmos 1009, as part of the Istrebitel Sputnikov programme.[2]

It was launched aboard a Kosmos-3M carrier rocket,[3] from Site 132/1 at the Plesetsk Cosmodrome. The launch occurred at 15:53 UTC on 13 December 1977.[4]

Kosmos 967 was placed into a low Earth orbit with a perigee of 961 kilometres (597 mi), an apogee of 1,003 kilometres (623 mi), 65.8 degrees of inclination, and an orbital period of 104.7 minutes.[1] It was successfully intercepted by Kosmos 970 in a non-destructive test on 21 December 1977. It was then re-used by Kosmos 1009 on 19 May 1978. Both tests were successful, and both left Kosmos 967 intact. As of 2023, it is still in orbit.[2][5]

Kosmos 967 was the seventh 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.
