From 1960 to 1973, Robert Bay was part of the team that helped get the United States into orbit and on to the moon. From the scrappy beginning, lofting men in a tiny Mercury spacecraft to the triumph of the moon landings, he was a witness and participant in one humanity's greatest endeavors. His memories form part of the history of the space race that is seldom told: The perspective of the average grunt, one of thousands, who worked tirelessly under enormous stress to make John F. Kennedy's challenge come true.
