William Alison Anders (born October 17, 1933) is a retired United States Air Force major general, former electrical engineer, nuclear engineer, NASA astronaut, and businessman. In December 1968, as a crew member of Apollo 8, he was one of the first three people to leave low Earth orbit and travel to the Moon. Along with fellow astronauts Frank Borman and Jim Lovell, Anders circled the Moon ten times and broadcast live images and commentary back to Earth. During one of the mission's lunar orbits, he photographed the iconic image Earthrise.
An astronaut (or cosmonaut) is a person trained by a human spaceflight program to command, pilot, or serve as a crew member of a spacecraft.
Although generally reserved for professional space travelers, the terms are sometimes applied to anyone who travels into space, including scientists, politicians, journalists, and tourists.
