Kosmos 76

Kosmos 76 (Russian: Космос 76 meaning Cosmos 76), also known as DS-P1-Yu No.3 was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles.[1] It was built by the Yuzhnoye Design Bureau, and launched in 1965 as part of the Dnepropetrovsk Sputnik programme.[2]

Kosmos 76 was launched using a Kosmos-2I 63S1 carrier rocket,[3] which flew from Site 86/1 at Kapustin Yar. The launch occurred at 04:33 UTC on 23 July 1965.[4]

Kosmos 76 separated from its carrier rocket into a low Earth orbit with a perigee of 255 kilometres (158 mi), an apogee of 499 kilometres (310 mi), 48.7 degrees of inclination, and an orbital period of 92.09 minutes.[2][5] It decayed from orbit on 16 March 1966.[5] Kosmos 76 was the third of seventy nine DS-P1-Yu satellites to be launched,[2] of which all but seven were successful. It replaced the previous satellite, DS-P1-Yu No.2, which had failed to reach orbit due to a second stage malfunction[2]
