Kosmos 393 (Russian: Космос 393 meaning Cosmos 393), known before launch as DS-P1-Yu No.34, was a Soviet satellite which was launched in 1971 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[edit]

Kosmos 393 was successfully launched into low Earth orbit on 26 January 1971, with the rocket lifting off at 12:44:33 UTC.[2] The launch took place from Site 133/1 at the Plesetsk Cosmodrome,[3] and used a Kosmos-2I 63SM carrier rocket.

Orbit[edit]

Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1971-007A.[4]

Kosmos 393 was the thirty-ninth of seventy nine DS-P1-Yu satellites to be launched,[1] and the thirty-sixth of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 263 kilometres (163 mi), an apogee of 451 kilometres (280 mi), 71 degrees of inclination, and an orbital period of 91.7 minutes.[1][6] It remained in orbit until it decayed and reentered the atmosphere on 16 June 1971.[6]
