Kosmos 423 (Russian: Космос 423 meaning Cosmos 423), known before launch as DS-P1-Yu No.47, 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 423 was successfully launched into low Earth orbit on 27 May 1971, with the rocket lifting off at 11:59:55 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 1971-047A.[4]
Kosmos 423 was the forty-third of seventy nine DS-P1-Yu satellites to be launched,[1] and the thirty-ninth of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 268 kilometres (167 mi), an apogee of 462 kilometres (287 mi), 71 degrees of inclination, and an orbital period of 91.8 minutes.[1][6] It remained in orbit until it decayed and reentered the atmosphere on 26 November 1971.[6]
