It is the dream of all children to become astronauts at one point or another, but very few actually get to. The term “astronaut” comes from two Greek words meaning “space sailor” and refers to all who have been launched as crew members aboard a 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 “space sailing” their professional career.
