Kosmos 295 (Russian: Космос 295 meaning Cosmos 295), known before launch as DS-P1-Yu No.29, was a Soviet satellite which was launched in 1969 as part of the Dnepropetrovsk Sputnik programme. It was a 325-kilogram (717 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.[1]


Kosmos 295 was launched from Site 133/1 at the Plesetsk Cosmodrome,[2] atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 22 August 1969 at 14:14:57 UTC, and resulted in Kosmos 295's successful deployment into low Earth orbit.[3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1969-073A.

Kosmos 295 was operated in an orbit with a perigee of 262 kilometres (163 mi), an apogee of 433 kilometres (269 mi), 70.9 degrees of inclination, and an orbital period of 91.5 minutes.[1][4] It remained in orbit until it decayed and reentered the atmosphere on 1 December 1969.[4] It was the twenty-fourth of seventy nine DS-P1-Yu satellites to be launched,[1] and the twenty-second of seventy two to successfully reach orbit.[5] Kosmos 295 replaced the previous DS-P1-Yu satellite, #23, which had failed to reach orbit due to a problem with the second stage of its carrier rocket.[1]
