Kosmos 558 (Russian: Космос 558 meaning Cosmos 558), known before launch as DS-P1-Yu No.65, was a Soviet satellite which was launched in 1973 as part of the Dnepropetrovsk Sputnik programme. It was a 400-kilogram (880 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.[1]


Kosmos 558 was successfully launched into low Earth orbit at 13:19:58 UTC on 17 May 1973.[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, the satellite was assigned its Kosmos designation, and received the International Designator 1973-029A.[4] The North American Aerospace Defense Command assigned it the catalogue number 06645.

Kosmos 558 was the sixty-second of seventy nine DS-P1-Yu satellites to be launched,[1] and the fifty-sixth of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 264 kilometres (164 mi), an apogee of 477 kilometres (296 mi), 70.9 degrees of inclination, and an orbital period of 92 minutes.[6] It remained in orbit until it decayed and reentered the atmosphere on 22 December 1973.[6]
