Kosmos 498 (Russian: Космос 498 meaning Cosmos 498), known before launch as DS-P1-Yu No.56, was a Soviet satellite which was launched in 1972 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]

Kosmos 498 was successfully launched into low Earth orbit at 09:29:58 UTC on 5 July 1972.[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 1972-050A.[4] The North American Aerospace Defense Command assigned it the catalogue number 06086.

Kosmos 498 was the fifty-fifth of seventy nine DS-P1-Yu satellites to be launched,[1] and the forty-ninth of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 266 kilometres (165 mi), an apogee of 461 kilometres (286 mi), 70.9 degrees of inclination, and an orbital period of 91.8 minutes.[6] It remained in orbit until it decayed and reentered the atmosphere on 25 November 1972.[6]
