Kosmos 356 (Russian: Космос 356 meaning Cosmos 356), also known as DS-U2-MG No.2, was a Soviet satellite which was launched in 1970 as part of the Dnepropetrovsk Sputnik programme. It was a 357-kilogram (787 lb) spacecraft,[1] which was built by the Yuzhnoye Design Bureau, and was used to investigate the magnetic poles of the Earth.[1]


A Kosmos-2I 63SM carrier rocket was used to launch Kosmos 356 into low Earth orbit. The launch took place from Site 133/1 at the Plesetsk Cosmodrome.[2] The launch occurred at 19:59:55 UTC on 10 August 1970, and resulted in the successful insertion of the satellite into orbit.[3] Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1970-059A.[4] The North American Aerospace Defense Command assigned it the catalogue number 04487.


Kosmos 356 was the second of two DS-U2-MG satellites to be launched, after Kosmos 321.[1][5] It was operated in an orbit with a perigee of 226 kilometres (140 mi), an apogee of 548 kilometres (341 mi), 81.9 degrees of inclination, and an orbital period of 92.3 minutes,[6] before decaying from orbit and reentering the atmosphere on 2 October 1970.[6]
