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 400 kilograms (880 lb) spacecraft,[1] which was built by the Yuzhnoye Design Office, and was used to conduct multispectral imaging of the Sun.[3]
Kosmos 166 was launched from Site 86/1 at Kapustin Yar, aboard a Kosmos-2I 63SM carrier rocket.[4] The launch occurred at 04:44:00 GMT on 16 June 1967, and resulted in the successful insertion of the satellite into a low Earth orbit.[5] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1967-061A.[1] The North American Air Defense Command assigned it the catalogue number 02848.[1]
Kosmos 166 was the first of two DS-U3-S satellites to be launched,[3] the other being Kosmos 230.[6] It was operated in an orbit with a perigee of 281 kilometres (175 mi), an apogee of 553 kilometres (344 mi), an inclination of 48.4°, and an orbital period of 92.6 minutes.[2] It completed operations on 26 September 1967,[7] before decaying from orbit and reentering the atmosphere on 25 October.[8]
