Kosmos 388 (ru|Космос 388 meaning Cosmos 388), known before launch as DS-P1-Yu No.43, was a Soviet satellite which was launched in 1970 as part of the Dnepropetrovsk Sputnik programme. It was a 325kg (717lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.[1]
Kosmos 388 was successfully launched into low Earth orbit on 18 December 1970, with the rocket lifting off at 09:39:13 UTC.[2] The launch took place from Site 133/1 at the Plesetsk Cosmodrome,[3] and used a Kosmos-2I 63SM carrier rocket. Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1970-112A.[4]
Kosmos 388 was the thirty-eighth of seventy nine DS-P1-Yu satellites to be launched,[1] and the thirty-fifth of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of, an apogee of, 70.9 degrees of inclination, and an orbital period of 92 minutes.[1] It remained in orbit until it decayed and reentered the atmosphere on 10 May 1971.[6]
