On this day in 1959 - April 9th - NASA selected its first group of astronauts, known as the Mercury Seven.

They were the pioneers of the US manned space program: Scott Carpenter, Gordon Cooper, John Glenn, Gus Grissom, Wally Schirra, Alan Shepard, and Deke Slayton. None of the Mercury Seven are still alive.
