In Russia April 12th is Cosmonautics Day. This holiday celebrates the first manned flight into space. This year marks the 51st anniversary of that space flight. Yuri Gagarin, a Soviet Cosmonaut, became the first man in space by orbiting around the Earth in a Vostok 1 spacecraft. His trip around the Earth lasted a total of 108 minutes. Exactly twenty years later NASA launched the first orbital flight of the space shuttles program. The Columbia went into space on April 12th, 1981 and orbited the Earth 37 times during the trip. Around the world April 12th is known as Yuri’s Night in commemoration of Yuri Gagarin’s first manned flight and the collective space exploration milestones reached since. If you would like to learn more about space and space travel you might enjoy a trip to the Chabot Space & Science Center. There is a multimedia exhibit called NASA’s Destination Station at The Tech Museum through this Sunday, April 15th.
