Kosmos 435

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]

Launch

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.

Orbit

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]

gollark: Oh, did you scroll down too far in it?
gollark: You have the manual. It has the rotation matrices.
gollark: Try not doing that.
gollark: No you didn't, you just flipped your chirality and caused a ΞK event in the power supply.
gollark: It harvests power from the universe it has in there, you don't need to provide any.
