Screening of military service records showed 110 military officers that met these criteria. These 110 were to be called in three groups for briefings on the Mercury program. Of the first two groups of 35 called, 56 volunteered for further physical and psychiatric tests. This provided enough candidates and the third group was never even called for a briefing or asked if they would like to volunteer. Of the 56 tested, seven were finally selected (no objective way was found to reduce the seven finalists to six).

Of the seven astronauts, all eventually flew in space. Grounded due to a heart murmur, Slayton had to wait 16 years for his flight aboard the last Apollo mission. Glenn left for a career in politics after becoming the first American to orbit the earth, but returned to space aboard a shuttle over 36 years later in a NASA publicity stunt. Schirra was the only astronaut to fly aboard Mercury, Gemini, and Apollo spacecraft. Shepard was the only one to reach the lunar surface (after being grounded for a medical condition during the Gemini program). Grissom would die in the Apollo 204 ground fire.
