John Glenn became an astronaut due to his passion for aviation and space exploration, combined with his desire to contribute to the United States' efforts in the Cold War space race against the Soviet Union. As a decorated Marine Corps pilot and a skilled test pilot, Glenn was selected for NASA's Mercury program, where he aimed to help expand human knowledge of space and inspire future generations. His historic orbital flight in 1962 made him a national hero and a symbol of American ingenuity.
