Kosmos 142 (Russian: Космос 142 meaning Cosmos 142), also known as DS-U2-I No.2, was a Soviet satellite which was launched in 1967 as part of the Dnepropetrovsk Sputnik programme. It was a 315 kilograms (694 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used to study the effects on radio waves of passing through the ionosphere.^[3]

A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 142 into low Earth orbit. The launch took place from Site 86/1 at Kapustin Yar.^[4] The launch occurred at 10:04:56 GMT on 14 February 1967, and resulted in the successful insertion of the satellite into orbit.^[5] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1967-013A.^[1] The North American Air Defense Command assigned it the catalogue number 02678.

Kosmos 142 was the second of three DS-U2-I satellites to be launched.^[6] It was operated in an orbit with a perigee of 207 kilometres (129 mi), an apogee of 1,336 kilometres (830 mi), an inclination of 48.4°, and an orbital period of 100.3 minutes.^[2] On 6 July 1967, it decayed from orbit and reentered the atmosphere.^[7]
