Mercury Atlas 8 (Sigma 7) launched 1962

Mercury-Atlas 8 astronaut Walter "Wally" Schirra, Jr.

Mission patch

Walter Schirra blasted off in Mercury-Atlas 8, Sigma 7 spacecraft, October 3, 1962.  It was the fifth manned mission of NASA's Mercury program and the third orbital mission.  Schirra orbited Earth 6 times in just over 9 hours.

The mission was considered a technical success since all engineering objectives were completed.  The spacecraft used less fuel than expected and Schirra returned healthy after nine hours in space.  However, heavy cloud cover and bad photography exposure of Earth's surface were not productive.  The mission wasn't hyped as much since the success of the previous two orbital flights and the Cuban Missile Crisis had the public's attention focused elsewhere.
