Here we see all of the Mercury 7 astronauts together, posing in front of an American Air Force aircraft. From left to right they are : Malcolm ‘Scott’ Carpenter, Gordon Cooper, John Glenn, Virgil I. Grissom, Walter ‘Wally’ Schirra, Alan B. Shepard and Donald ‘Deke’ Slayton. Except for Donald Slayton all them would all become the first Americans to fly in Space. Walter Schirra would have the distinction of being the only member of this group to fly in all three of the first American manned space programmes – Mercury, Gemini and Apollo. Alan B. Shepard would be the only member of this exclusive band of top test pilots to walk on The Moon, during the Apollo 14 mission. Image Courtesy of NASA.
