Kosmos 408 (Russian:Космос 408 meaningCosmos 408), known before launch asDS-P1-Yu No.37, was aSovietsatellite which was launched in 1971 as part of theDnepropetrovsk Sputnik programme. It was a 250-kilogram (550 lb) spacecraft, which was built by theYuzhnoye Design Bureau, and was used as a radar calibration target foranti-ballistic missile tests.[1]
Kosmos 408 was successfully launched intolow Earth orbit on 24 April 1971, with the rocket lifting off at 11:15:02 UTC.[2] The launch took place fromSite 133/1 at thePlesetsk Cosmodrome,[3] and used aKosmos-2I 63SMcarrier rocket.
Upon reaching orbit, it was assigned itsKosmos designation, and received theInternational Designator 1971-037A.[4]
Kosmos 408 was the forty-first of seventy nineDS-P1-Yu satellites to be launched,[1] and the thirty-seventh of seventy two to successfully reach orbit.[5] It was operated in an orbit with aperigee of 197 kilometres (122 mi), anapogee of 1,383 kilometres (859 mi), 81.8 degrees ofinclination, and anorbital period of 100.66 minutes.[1][6] It remained in orbit until itdecayed and reentered the atmosphere on 29 December 1971.[6]
