尤里·加加林——太空第一人 Yuri Gagarin——First Man in Space
Yuri A. Gagarin was born on a collective farm in a region west of Moscow, Russia on March 9th, 1934. His father was a carpenter[木匠]. Yuri attended the local school for six years and continued his education at vocational[职业的] and technical schools.
Yuri Gagarin joined the Russian Air Force in 1955 and graduated with honors[优等成绩] from the Soviet Air Force Academy in 1957. Soon afterward, he became a military fighter pilot. By 1959, he had been selected for cosmonaut training as part of the first group of USSR cosmonauts.
Yuri Gagarin flew only one space mission. On April 12th, 1961 he became the first human to orbit Earth. Gagarin’s spacecraft, Vostok 1, circled Earth at a speed of 27,400 kilometers per hour. The flight lasted 108 minutes.
Once in orbit, Yuri Gagarin had no control over his spacecraft. Vostok’s reentry[重新进入] was controlled by a computer program sending radio commands to the space capsule[太空舱]. Although the controls were locked, a key had been placed in a sealed envelope in case an emergency situation made it necessary for Yuri Gagarin to take control. As was planned, Cosmonaut Yuri Gagarin ejected[弹射出] after reentry into Earth’s atmosphere[大气] and landed by parachute[降落伞].
Yuri Gagarin died on March 27th, 1968 when the MiG-15 he was piloting crashed[坠毁] near Moscow. At the time of his death, Yuri Gagarin was in training for a second space mission.
