Vostok 1

spaceflight of the Vostok programme

Vostok 1 (Russian: Восто́к, East or Orient 1) was the first flight to take a human into space. It used a Vostok 3KA spacecraft, and was launched on April 12, 1961.[7] 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.[7]: 53  The Vostok 1 was launched by the Soviet space program and made by the Soviet rocket scientists Sergei Korolev and Kerim Kerimov.

Manned flights

The Vostok spacecraft weighed 4.73 t (10,400 lb), was 4.4 m (14 ft) long and 2.43 m (8.0 ft) in diameter.[7]: 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 in case of an emergency. The flight was simple, the cosmonaut was simply a passenger.[7]: 52  There were controls for use in an emergency.[8] The spacecraft had a food locker, radio, a cabinet with experiments inside, and two windows, one above the ejection seat and one to the right.. Gagarin ejected from the spacecraft after re-entry and landed by parachute.

There were six manned Vostok flights, the last one, Vostok 6, carried Valentina Tereshkova, the first woman to go into space on June 16, 1963.[7]: 53
