Glenn does his astronaut homework in Florida in 1959. "We spent a lot of time testing and studying and re-testing systems we'd be dealing with on any craft that might eventually be sent into space," Glenn remembered. "We had never dealt with those systems before: They were invented just for this project." Ralph Morse/Time & Life Pictures/Getty Images

Glenn announces his candidacy for US Senate in 1964. "In his only previous contacts with high-level politicians of both parties," Life magazine wrote, "Glenn has been the object of admiration and affection; for the people in general he has been virtually above reproach. Now, suddenly, his hero's immunity is gone. He must stand still for hard looks and hard questions by men who have long studied all the answers." Ralph Morse/Time & Life Pictures/Getty Images
