Sputnik 2 was built in about four months. The satellite was launched on November 3, 1957, shortly after its predecessor, Sputnik 1, which had been launched just a month earlier. This rapid development was part of the Soviet Union's intense competition in the Space Race during the Cold War. Sputnik 2 famously carried the first living creature into space, a dog named Laika.
