1 At 12th April, 1961 Yuri Gagarin, a Russian Cosmonaut,
2 became first human to travel into space. Although his flight
3 lasted only 108 minute, its success made him
4 national hero. He also became the first person
5 ate and drank in zero gravity, and he was able
6 view the Earth in a way that no one had done before.
7 Unfortunately, a plane crash in March 1968 made Gagarins’
8 desire of revisiting space unpossible.
9 After his dead, his hometown and the Cosmonaut Training
10 Center at Star City, Russia, was named after he.
