The third American in space, John Glenn was the first of the original group of astronauts ("The Mercury 7") to orbit the earth, which he did in Friendship 7 on February 20, 1962; this photograph was taken at the parade celebrating that feat. Glenn came to NASA after a distinguished career in the Marine Corps. He was a fighter pilot during both World War II and Korea, and afterward he became a test pilot, making some of the first supersonic flights. Glenn left the space program soon after his orbital mission. After a career in business he entered politics, serving as a Democratic senator from his home state of Ohio from 1974 to 1995. In 1998, at age seventy-seven, he returned to space, flying on a mission of the shuttle Discovery.
