John Herschel Glenn, Jr. (born July 18, 1921) is a former United States Marine Corps pilot, astronaut, and United States senator who was the first American to orbit the Earth and the third American in space. Glenn was a Marine Corps fighter pilot before joining NASA's Mercury program as a member of NASA's original astronaut group. He orbited the Earth in Friendship 7 in 1962. After retiring from NASA, he entered politics as a Democrat and represented Ohio in the United States Senate from 1974 to 1999.
Glenn received a Congressional Space Medal of Honor in 1978. He was inducted into the Astronaut Hall of Fame in 1990. On October 29, 1998, he became the oldest person to fly in space, and the only one to fly in both the Mercury and Space Shuttle programs, when at age 77, he flew on Discovery (STS-95). As of 2010, Glenn and M. Scott Carpenter are the last living members of the Mercury Seven.
