Sputnik 2
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]
