Profile of John Glenn

On February 20, 1962, John Glenn piloted the Mercury-Atlas 6 "Friendship 7" spacecraft on the first manned orbital mission of the United States. Launched from Cape Canaveral (Florida) Launch Complex 14, he completed a successful three-orbit mission around the earth, reaching a maximum altitude (apogee) of approximately 162 statute miles and an orbital velocity of approximately 17,500 miles per hour. Glenn's "Friendship 7" Mercury spacecraft landed approximately 800 miles southeast of Cape Canaveral in the vicinity of Grand Turk Island. His flight on Friendship 7 on Feb. 20, 1962, showed the world that America was a serious contender in the space race with the Soviet Union. It also made Glenn an instant hero.

This site hosted by NASA contains biographical information, photos, and videos about astronaut, former Marine, and former Senator John Glenn, who passed away December 8, 2016.
