Kosmos 351 (Russian: Космос 351 meaning Cosmos 351), known before launch as DS-P1-Yu No.38, was a Soviet satellite which was launched in 1970 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]

Launch

Kosmos 351 was launched from Site 133/1 at the Plesetsk Cosmodrome,[2] atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 27 June 1970 at 07:39:55 UTC, and resulted in the successful deployment of Kosmos 351 into low Earth orbit.[3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1970-051A.[4]

Orbit

Kosmos 351 was the thirty-fourth of seventy nine DS-P1-Yu satellites to be launched,[1] and the thirty-first of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 261 kilometres (162 mi), an apogee of 429 kilometres (267 mi), 70.9 degrees of inclination, and an orbital period of 91.43 minutes.[1][6] It remained in orbit until it decayed and reentered the atmosphere on 13 October 1970.[6]
