Venera 2MV-1 No.2,[2][1] also known as Sputnik 20 in the Western world, was a Soviet spacecraft, which was launched in 1962 as part of the Venera programme. Due to a problem with its upper stage it failed to leave low Earth orbit, and reentered the atmosphere a few days later.[3] It was the second of two Venera 2MV-1 spacecraft, both of which failed to leave Earth orbit. The previous mission, Venera 2MV-1 No.1, was launched several days earlier.[1]
