Kosmos 135 (Russian: Космос 135 meaning Cosmos 135), also known as DS-U2-MP No.1, was a Soviet satellite which was launched in 1966 as part of the Dnepropetrovsk Sputnik programme. It was a 280-kilogram (620 lb) spacecraft,[1] which was built by the Yuzhnoye Design Bureau, and was used to investigate micrometeoroids and particles of dust in space.[2]

A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 135 into low Earth orbit. The launch took place from Site 86/1 at Kapustin Yar.[3] The launch occurred at 20:37:59 GMT on 12 December 1966, and resulted in the successful insertion of the satellite into orbit.[4] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1966-112A.[5] The North American Aerospace Defense Command assigned it the catalogue number 02612.

Kosmos 135 was the first of two DS-U2-MP satellites to be launched, the other being Kosmos 163.[2][6] It was operated in an orbit with a perigee of 251 kilometres (156 mi), an apogee of 604 kilometres (375 mi), 48.4 degrees of inclination, and an orbital period of 93.12 minutes.[7] It decayed from its orbit and reentered the atmosphere on 12 April 1967.[7]
