(Russian) A satellite, spacecraft. A Russian artificial satellite.
Series of ten Soviet Earth-orbiting satellites. Sputnik 1 was the first artificial satellite, launched 4 Oct 1957. It weighed 84 kg/185 lb, with a 58 cm/23 in diameter, and carried only a simple radio transmitter which allowed scientists to track it as it orbited Earth. It burned up in the atmosphere 92 days later. Sputniks were superseded in the early 1960s by the Cosmos series.
Sputnik 2, launched 3 Nov 1957, weighed about 500 kg/1,100 lb including the dog Laika, the first living creature in space. Unfortunately, there was no way to return the dog to Earth, and it died in space. Later Sputniks were test flights of the Vostok spacecraft.
