Sputnik 2 was a Soviet Union spacecraft. It was the second spacecraft in the Sputnik programme. It was the first spacecraft to carry a living animal, a dog called Laika.[2] It was launched on 3 October 1957 at Baikonur Cosmodrome.[2] Scientists think that Laika died several hours after launch from overheating. The spacecraft went into orbit around Earth for roughly five months.[2] It went down into Earth's atmosphere on 14 April 1958 and burned up.[2]
Sputnik 2 was 4 metres (13 feet) high and its base diameter was 2 metres (6.6 feet).[2] It was a cone-shaped and it had several different places for radio transmitters, a telemetry system, a programming unit, a regeneration and temperature control system for the spacecraft, and scientific instruments.[2] Laika was put in a special area.[2]
