Buzz Aldrin - Yeah, Neil made the first bootprint, but has been nearly silent ever since. Meanwhile Buzz, with far less name recognition, has tirelessly dedicated himself to promoting the space program with speeches, books, signings - anything he can do to promote enthusiasm for science and space exploration. Buzz was no less brave and bold for having made his bootprint a few minutes after Neil. But he has been far braver and bolder ever since. I vote for Buzz.
