Wally Schirra was one of the famed original Mercury astronauts. He had missions to space during the Mercury, Gemini and Apollo programs. Schirra flew on Mercury 8, the fifth of the solo Mercury missions. He then went on to be a part of Gemini 6A with Tom Stafford in the first crewed spacecraft rendezvous. Schirra commanded the first crewed flight of the Apollo program - Apollo 7 - after the tragic Apollo 1 fire that killed Gus Grissom, Ed White and Roger Chaffee. Schirra graduated from the U.S. Naval Academy and served during World War II and the Korean War.

Rusty Schweickart was the lunar module pilot on Apollo 9, the third manned flight of the Apollo program, during which he tested the astronauts' portable life support backpack later used on moon missions. He spent 241 hours in space, including that 46-minute EVA testing the backpack. Following his Apollo flight, he served as a backup commander of the first crewed Skylab mission.
