Kosmos 435 was successfully launched into low Earth orbit on 27 August 1971, with the rocket lifting off at 10:54:56 UTC. The launch took place from Site 133/1 at the Plesetsk Cosmodrome, 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.
Kosmos 435 was the forty-fifth of seventy nine DS-P1-Yu satellites to be launched, and the fortieth of seventy two to successfully reach orbit. 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. It remained in orbit until it decayed and reentered the atmosphere on 28 January 1972.
