Mercury Astronauts at April 9, 1959, News Conference
During the April 9, 1959 news conference that introduced the Mercury astronauts, they were asked, "Who wants to be the first man launched into space?" all seven raised their hands -- Walter Schirra and John Glenn raising both hands. From the left, are Donald Slayton, Alan Shepard, Schirra, Gus Grissom, Glenn, Gordon Cooper and Scott Carpenter.
Alan Shepard Speaks with Gus Grissom
Alan Shepard speaks with Gus Grissom (on left, back to camera), prior to climbing aboard his Freedom 7 capsule for his Mercury-Redstone 3 mission on May 5, 1961. John Glenn (behind Shepard) waits to help strap Shepard into the spacecraft.
Wernher von Braun and Gordon Cooper
Marshall Space Flight Center Director Wernher von Braun looks on as Gordon Cooper serves as capsule communicator, or cap comm, for Alan Shepard's Mercury Redstone-3 countdown in the blockhouse at Cape Canaveral Air Force Station's Launch Pad 5. Astronauts serve as "cap. Comms." to facilitate only one voice speaking to the spacecraft pilots.

Gordon Cooper Departs the Crew Quarters
On May 15, 1963, Gordon Cooper departs the crew quarters at Hangar S for the trip to Launch Pad 14 for the Mercury Atlas-9 mission to orbit the Earth 22 times. Following astronaut Cooper to the transfer van is Walter Schirra.

The National Aeronautics and Space Administration came into being on October 1, 1958. NASA announced the seven Project Mercury Astronauts on April 9, 1959, only six months later. They are: (front, l to r) Walter H. Schirra, Jr., Donald K. Slayton, John H. Glenn, Jr., and Scott Carpenter; (back, l to r) Alan B. Shepard, Jr., Virgil I. Gus Grissom, and L. Gordon Cooper.
