An astronaut is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft. There are three types of astronauts in the U.S. space program: the commander/pilot, mission specialist, and payload specialist. The commander is responsible for the mission, the crew and the vehicle. The pilot assists the commander in operating the vehicle and deploying satellites. The mission specialist works with the commander and pilots in shuttle operations, performs spacewalks and conducts experiments. The payload specialist performs specialized duties as the mission requires. Payload specialists are people other than NASA personnel, and some are foreign nationals.
