Project Summary

Project Mercury represented America's first efforts to send men into space. The first two Mercury missions were launched on sub-orbital flights by Redstone rockets to test the ability of humans to survive the high G-forces of lift-off and the ability of the small Mercury capsule to keep the single astronaut alive in the vacuum of space. Later Mercury missions were sent into orbit around the Earth by more powerful Atlas rockets. Each mission expanded on the experience that was gained in the previous flight, culminating in the 32-hour flight of Faith 7.

A piece of space history from the Mercury program was brought back home in April 1999, when the Liberty Bell 7 capsule flown by astronaut Virgil "Gus" Grisson in July 1961 was found 3 miles beneath the Atlantic and recovered basically intact. The capsule sank following Grissom's successful sub-orbital flight when the escape hatch unexpectedly blew open while Grissom was waiting to be recovered.
