东方-K | Vostok 5

描述

The Vostok-K was an expendable carrier rocket used by the Soviet Union for thirteen launches between 1960 and 1964, six of which were manned. The Vostok-K made its maiden flight on 22 December 1960, three weeks after the retirement of the Vostok-L. The third stage engine failed 425 seconds after launch, and the payload, a Korabl-Sputnik spacecraft, failed to reach orbit. The spacecraft was recovered after landing, and the two dogs aboard the spacecraft survived the flight. On 12 April 1961, a Vostok-K rocket was used to launch Vostok 1, the first manned spaceflight, which made Yuri Gagarin the first human to fly in space.

东方-K（Vostok-K）是苏联使用的一款一次性运载火箭，于 1960 至 1964 年间共发射十三次，其中六次为载人飞行。 东方-K 于 1960 年 12 月 22 日首飞，距东方-L 退役三周。发射 425 秒后第三级发动机故障，其载荷——一艘“卫星飞船”（Korabl-Sputnik）——未能入轨。该飞船着陆后被回收，船上两只狗在飞行中幸存。 1961 年 4 月 12 日，一枚东方-K 火箭用于发射东方 1 号（Vostok 1），即首次载人航天飞行，使尤里·加加林成为首位进入太空的人类。
