Historic Milestones in Space Exploration

Milestones in Space Exploration History

Sixty years ago, Russian cosmonaut Yuri Gagarin made history when he became the first man to fly into space. Gagarin spent 108 minutes in a tiny Vostok 1 space capsule, completing an orbit around the Earth on April 12, 1961. His groundbreaking mission raised the stakes in the space race between the Soviet Union and the United States. Here are some other famous firsts in the history of space exploration.

Less than a month after Gagarin's trip, astronaut Alan Shepard became the first American to travel into space. On May 5, 1961, Shepard piloted Freedom 7, the first manned mission in the Mercury program. His suborbital flight lasted a little more than 15 minutes.
