(spût -nik) Any of a series of Soviet artificial satellites, the first of which – Sputnik 1 – was the first spacecraft to be placed in orbit. This 58-cm diameter sphere, weighing 84 kg, was launched on Oct. 4 1957; it burnt up in the Earth's atmosphere 92 days later. The orbit had a period of 96 minutes, an apogee and perigee (highest and lowest altitudes) of about 950 km and 230 km, and was inclined at 65° to the equator. Its radio signals were transmitted every 0.6 seconds. It contained few instruments, being intended as a test vehicle. The launching of Sputnik 1 had a profound effect in accelerating America's space program.

Sputnik 2, launched on Nov. 3 1957, was very much bigger. It carried about 500 kg in payload, including a live dog, Laika, which survived the launch, as well as 10 experiments. Sputnik 3, launched on May 15 1958, weighed about 1330 kg and remained in orbit for 691 days.
