Astronaut Facts
Astronauts are people that are trained in a spaceflight program to serve as a crew member, a pilot, or a commander aboard a spacecraft. The term can also sometimes be used to refer to others who travel into space including scientists and journalists and tourists. Astronauts originally were trained by governments exclusively until 2002 but since then commercial astronauts have also been trained by private funds. The term astronaut is derived from Greek words meaning 'star sailor'. The first human to go to space was Yuri Gagarin in 1961. The first woman was Valentina Tereshkova in 1963.
