Astronauts

The term “astronaut” derives from the Greek words meaning “star sailor,” and refers to all who have been launched as crew members aboard NASA spacecraft bound for orbit and beyond. The term “astronaut” has been maintained as the title for those selected to join the NASA corps of astronauts who make “star sailing” their career profession.
