Vostok 1 (Russian: Восток-1) meaning Orient 1 or East 1 was the first flight to take a human into space. It used a Vostok 3KA spacecraft, and was launched on April 12, 1961. It took into space Yuri Gagarin, a cosmonaut from the Soviet Union. The Vostok 1 mission was the first time a person went into outer space and the first time anyone had entered into orbit. The flight made one orbit and lasted for 1 hour, 48 minutes.:53 The Vostok 1 was launched by the Soviet space program and made by the Soviet rocket scientists Sergey Korolyov and Kerim Kerimov.
The Vostok spacecraft weighed 4.73 tonne, was 4.4 m (14 ft) long and 2.43 m (8 ft) in diameter.:52 The cosmonaut flew inside a spherical module. He sat on a seat which was also an ejection seat which allowed the cosmonaut to escape from the spacecraft. The flight was simple, the cosmonaut was simply a passenger.:52 There were controls for use in an emergency. The spacecraft had a food locker, radio, an experiment cabinet, and a round window. Gagarin ejected from the spacecraft after re-entry and landed by parachute.
