Kosmos 435 (Russian: Космос 435 meaning Cosmos 435), known before launch as DS-P1-Yu No.41, was a Soviet satellite which was launched in 1971 as part of the Dnepropetrovsk Sputnik programme. It was a 325-kilogram (717 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests.[1]


Kosmos 435 was successfully launched into low Earth orbit on 27 August 1971, with the rocket lifting off at 10:54:56 UTC.[2] The launch took place from Site 133/1 at the Plesetsk Cosmodrome,[3] and used a Kosmos-2I 63SM carrier rocket.


Upon reaching orbit, it was assigned its Kosmos designation, and received the International Designator 1971-072A.[4]

Kosmos 435 was the forty-fifth of seventy nine DS-P1-Yu satellites to be launched,[1] and the fortieth of seventy two to successfully reach orbit.[5] It was operated in an orbit with a perigee of 265 kilometres (165 mi), an apogee of 455 kilometres (283 mi), 70.9 degrees of inclination, and an orbital period of 91.8 minutes.[1][6] It remained in orbit until it decayed and reentered the atmosphere on 28 January 1972.[6]
