Leroy Gordon Cooper Jr., one of the "Original Seven" astronauts, was born on March 6, 1927, in Shawnee, Oklahoma.
Astronaut Gordon Cooper flew the final Mercury mission and was, therefore, the last American to fly in space alone. His second and final mission — the two-man, eight-day Gemini 5 —proved that astronauts could endure the time in space needed to accommodate a trip to the moon. (Photo: @NASA)
