What Happened on Alan Shepard's First Spaceflight?
On May 5, 1961, Alan Shepard became the first American in space. He flew on a Mercury spacecraft. There was just enough room for one person. He named his capsule Freedom 7. It launched on a Redstone rocket. The Army first used the Redstone as a missile. On this flight, Shepard did not orbit Earth. He flew 116 miles high. Then he came back down. The flight lasted about 15 ½ minutes. The mission was a success.
