Not much. It orbited the Earth, emitting radio beeps for 21 days until the transmitter batteries ran out on 26 October 1957. Sputnik 1 orbited until 4 January 1958, having completed 1,440 orbits of the Earth. It burned up on 4 January 1958, as it fell from orbit upon reentering the Earth's atmosphere.

Sputnik 1 was the world's first artificial satellite launched by the Soviet Union in 1957. It marked the beginning of the space race between the US and the Soviet Union during the Cold War. Sputnik 1 orbited Earth for three months, transmitting radio signals back to Earth before burning up upon re-entry into the atmosphere.
