Kosmos 378 (Russian: Космос 378 meaning Cosmos 378), also known as DS-U2-IP No.1, was a Soviet satellite which was launched in 1970 as part of the Dnepropetrovsk Sputnik programme. It was a 710-kilogram (1,570 lb) spacecraft,[1] which was built by the Yuzhnoye Design Bureau, and was used to study the ionosphere.[1]


A Kosmos-3M 11K65M carrier rocket, serial number 47117-107, was used to launch Kosmos 378 into low Earth orbit.[2] It was launched at 18:20:01 UTC on 17 November 1970, from Site 132/2 at the Plesetsk Cosmodrome.[2] The launch 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 1970-097A.[4] The North American Aerospace Defense Command assigned it the catalogue number 04713.


Kosmos 378 was the only DS-U2-IP satellite to be launched.[1][5] It was operated in an orbit with a perigee of 233 kilometres (145 mi), an apogee of 1,697 kilometres (1,054 mi), 74 degrees of inclination, and an orbital period of 104.4 minutes.[6] It completed operations on 13 September 1971,[7] before decaying from orbit and reentering the atmosphere on 17 August 1972.[6]
