This spacesuit was worn by Gordon Cooper during training sessions prior to the last orbital flight of the Mercury program on May 15, 1963. The flight lasted over 34 hours, during which time the automatic control system suffered a major malfunction requiring a manual re-entry, which was performed flawlessly.
The spacesuit was developed by the B.F. Goodrich Company from the U.S. Navy MK-IV full pressure suit and was selected by NASA in 1959 for use in Project Mercury.
The suit was transferred to the National Air and Space Museum from NASA in 1970.
