Kosmos 303 ( Russian: Космос 303 meaning Cosmos 303), known before launch as DS-P1-Yu No.28, was a Soviet satellite which was launched in 1969 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
Kosmos 303 was launched from Site 133/1 at the Plesetsk Cosmodrome, [2] atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 18 October 1969 at 10:00:03 UTC, and resulted in the successful deployment of Kosmos 303 into low Earth orbit. [3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1969-090A.
Kosmos 303 was operated in an orbit with a perigee of 259 kilometres (161 mi), an apogee of 426 kilometres (265 mi), 71 degrees of inclination, and an orbital period of 91.4 minutes. [1] [4] It remained in orbit until it decayed and reentered the atmosphere on 23 January 1970. [4] It was the twenty-fifth of seventy nine DS-P1-Yu satellites to be launched, [1] and the twenty-third of seventy two to successfully reach orbit. [5]
