Welcome to the astronaut biographies home page, providing biographical information on the members of the space flight crews and candidates for future missions in NASA's space flight program
About Astronauts

The term "astronaut" derives from the Greek words meaning "space sailor," and refers to all who have been launched as crew members aboard NASA spacecraft bound for orbit and beyond. Since the inception of NASA's human space flight program, we have also maintained the term "astronaut" as the title for those selected to join the NASA corps of astronauts who make "space sailing" their career profession. The term "cosmonaut" refers to those space sailors who are members of the Russian space program.

The crew of each launched spacecraft is made up of astronauts or cosmonauts drawn from the various categories described in these pages. The crew assignments and duties of commander, pilot, or International Space Station flight engineer are drawn from the NASA professional career astronauts. A special category of astronauts typically titled "payload specialist" refers to individuals selected and trained by commercial or research organizations for flights of a specific payload on a space flight mission.

The links to the left will direct you to biographical information on the astronauts. These biographies are prepared by the Astronaut Office of the Johnson Space Center and are provided through the Internet as a public service.
