A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 173 from Site 133/1 at Plesetsk Cosmodrome.[4] The launch occurred at 04:59:49 GMT on 24 August 1967, and resulted in Kosmos 173's successful deployment into low Earth orbit.[5]
Kosmos 173 was operated in an orbit with a perigee of 277 kilometres (172 mi), an apogee of 480 kilometres (300 mi), an inclination of 71.0°, and an orbital period of 92.3 minutes.[2] It remained in orbit until it decayed and reentered the atmosphere on 17 December 1967.[6] It was the ninth of seventy nine DS-P1-Yu satellites to be launched,[3] and the eighth of seventy two to successfully reach orbit.[7]
