Kosmos 222 was launched from Site 133/3 at the Plesetsk Cosmodrome,[2] atop a Kosmos-2I 63SM carrier rocket. The launch occurred on 30 May 1968 at 20:29:49 GMT, and resulted in Kosmos 222's successful deployment into low Earth orbit.[3] Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1968-044A.
Kosmos 222 was operated in an orbit with a perigee of 285 kilometres (177 mi), an apogee of 488 kilometres (303 mi), an inclination of 71.0°, and an orbital period of 92.3 minutes.[1][4] It remained in orbit until it decayed and reentered the atmosphere on 11 October 1968.[4] It was the fourteenth of seventy nine DS-P1-Yu satellites to be launched,[1] and the thirteenth of seventy two to successfully reach orbit.[5]
