NASA Astronaut Group 4

Astronaut Group 4 was the fourth group of astronauts selected by NASA in June 1965. While the astronauts of the previous three groups were required to have college degrees, they were primarily chosen for their test pilot backgrounds. The six members of Group 4, on the other hand, were chosen for their research and academic backgrounds (Doctorate degrees were required and minimum flight time requirements were waived). Of the six, only Schmitt, a geologist, walked on the Moon. Garriott, Gibson and Kerwin all flew to Skylab. Garriott also flew on the Space Shuttle. Graveline and Michel left NASA without flying in space.
