Kosmos 101 (Russian: Космос 101 meaning Cosmos 101), also known as DS-P1-Yu No.4 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]

The launch of Kosmos 101 was conducted using a Kosmos-2I 63S1 carrier rocket,[3] which flew from Site 86/1 at Kapustin Yar. The launch occurred at 06:14 GMT on 21 December 1965.[4]

Kosmos 101 separated from its carrier rocket into a low Earth orbit with an apogee of 510 kilometres (320 mi), a perigee of 255 kilometres (158 mi), 48.8 degrees of inclination, and an orbital period of 92.20 minutes.[2][5] It decayed from orbit on 12 July 1966.[5] Kosmos 101 was the fourth of seventy nine DS-P1-Yu satellites to be launched,[2] of which all but seven were successful.
