Kosmos 221 (Russian: Космос 221 meaning Cosmos 221), also known as DS-P1-Yu No.14, was a Soviet satellite which was used as a radar calibration target for tests of anti-ballistic missiles. It was built by the Yuzhnoye Design Bureau, and launched in 1968 as part of the Dnepropetrovsk Sputnik programme.[1] It had a mass of 400 kilograms (880 lb).[1]
Kosmos 221 was launched from Site 86/4 at Kapustin Yar,[2] atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 24 May 1968 at 07:04:50 GMT, and resulted in Kosmos 221's successful deployment into low Earth orbit.[3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1968-043A.
Kosmos 221 was operated in an orbit with a perigee of 218 kilometres (135 mi), an apogee of 2,086 kilometres (1,296 mi), an inclination of 48.4°, and an orbital period of 108.3 minutes.[1][4] It remained in orbit until it decayed and reentered the atmosphere on 31 August 1969.[4] It was the thirteenth of seventy nine DS-P1-Yu satellites to be launched,[1] and the twelfth of seventy two to successfully reach orbit.[5]
