Kosmos 166 (Russian: Космос 166 meaning Cosmos 166), also known as DS-U3-S No.1, was a satellite which was launched by the Soviet Union in 1967 as part of the Dnepropetrovsk Sputnik programme. It was a 285-kilogram (628 lb) spacecraft,[1] which was built by the Yuzhnoye Design Bureau, and was used to conduct multispectral imaging of the Sun.[2]

Kosmos 166 was launched from Site 86/1 at Kapustin Yar, aboard a Kosmos-2I 63SM carrier rocket.[3] The launch occurred at 04:43:59 UTC on 16 June 1967, and resulted in the successful insertion of the satellite into a low Earth orbit.[4] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1967-061A.[5] The North American Aerospace Defense Command assigned it the catalogue number 02848.

Kosmos 166 was the first of two DS-U3-S satellites to be launched,[2] the other being Kosmos 230.[6] It was operated in an orbit with a perigee of 277 kilometres (172 mi), an apogee of 534 kilometres (332 mi), 48.4 degrees of inclination, and an orbital period of 92.7 minutes.[7] It completed operations on 26 September 1967,[1] before decaying from orbit and reentering the atmosphere on 25 October.[7]
