NASA Astronaut Group 3 NASA Astronaut Group 3 Astronaut Group 3 was a group of fourteen astronauts selected by NASA. Their selection was announced in October 1963. Four died in training accidents before they could fly in space. All of the surviving ten flew in the Apollo program; five also flew Gemini missions. Aldrin, Bean, Cernan and Scott walked on the Moon. They are the only ones of the first 19 NASA astronaut groups to have no members at all fly on the Space Shuttle. Group 3 was the first to waive the requirement of a test pilot background, though military jet fighter aircraft

Multiple factors contributed to the final decision, including the physical positioning of the astronauts within the compact lunar lander, which made it easier for Armstrong to be the first to exit the spacecraft. Furthermore, there was little support for Aldrin's views among other senior astronauts who would command later Apollo missions, and who may have been the first to make a lunar landing had Apollo 11 failed.
