Unplugged: Buzz Aldrin Promotes Mission to Mars

"[I]t is time to move on back into exploration. And I think now, with the new administration we are wisely re-evaluating the path," Aldrin told moderator Bob Orr.

The former astronaut announced his proposal to launch a mission Mars "to ensure American space leadership for the 21st century" in an editorial in the Washington Post this morning.

Aldrin told Orr that he never felt like a hero during his 1969 mission rather "we felt like very fortunate people being given the opportunity to be responsible, alert and to carry out our task...enjoying what we were doing but also paying very close attention to our once in a lifetime opportunity that just came along."
