John Glenn On 50 Years Since His First Orbit
Monday marks the 50th anniversary of astronaut John Glenn's orbiting of Earth. Glenn — who was one of NASA's original Mercury Seven — was the first American to achieve the feat. He flew the mission in just under five hours, circling the globe three times in a capsule named Friendship 7. Glenn, who says he recalls the mission as if it were just last week, tells Audie Cornish he doesn't want the US to lose sight of the future and America's role in outer space.
