Kosmos 173 (Russian: Космос 173 meaning Cosmos 173), also known as DS-P1-Yu No.8 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 1967 as part of the Dnepropetrovsk Sputnik programme.[1]

A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 173 from Site 133/1 at Plesetsk Cosmodrome.[2] The launch occurred at 04:59:49 UTC on 24 August 1967, and resulted in Kosmos 173's successful deployment into low earth orbit.[3]

Kosmos 173 was operated in an orbit with a perigee of 261 kilometres (162 mi), an apogee of 471 kilometres (293 mi), 71.0 degrees of inclination, and an orbital period of 91.86 minutes.[1][4] It remained in orbit until it decayed and reentered the atmosphere on 17 December 1967.[4] It was the ninth of seventy nine DS-P1-Yu satellites to be launched,[1] and the eighth of seventy two to successfully reach orbit.[5]
