Happy birthday, John Glenn! Born on July 18, 1921, he was a U.S. Marine who served in both World War II and the Korean War. In 1959, he was chosen as one of the original group of seven astronauts for NASA’s Project Mercury, and then on February 20, 1962, he became the first American to orbit Earth, as well as the fifth human in space.
After many years in the military and at NASA, Glenn served as a US Senator from Ohio for 24 years. In 1998, at the age of 77, Glenn returned to space to study the effects of space flight on the elderly.
