This spacesuit was worn by John Glenn during the first orbital flight of a U.S. astronaut. The flight took place on February 20, 1962 and lasted for 4 hours and 55 minutes, during which time he traveled 75,679 miles and orbited the earth three times. This 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.
