单词 Vostok
释义
Vostok

Space Exploration
  • A Soviet single-seater spacecraft consisting of a metal sphere 2.3 m in diameter in which the cosmonaut sat on an ejector seat. After re-entry of Vostok through the atmosphere, the cosmonaut ejected from the capsule and landed separately by parachute. Vostok 1, launched on 12 April 1961, carried the first human in space, Yuri Gagarin, who made a single-orbit flight lasting 108 minutes. On Vostok 2, launched on 6 August 1961, Gherman Titov made the first day-long space flight. Vostok 3 was launched on 11 August 1962 carrying Andrian Nikolayev, who was joined in orbit a day later by Pavel Popovich aboard Vostok 4. On 14 June 1963 Valery Bykovsky was launched in Vostok 5 on a five-day flight, during which he made 81 orbits of the Earth, the longest-ever individual space flight. While Vostok 5 was still in orbit, the first woman in space, Valentina Tereshkova, was launched aboard Vostok 6, the last of the series. The Vostok was little more than an automatic capsule with a passenger, and the basic design is still used to carry payloads into Earth orbit that need to be recovered afterwards, such as biological specimens and reconnaissance cameras.
