Considering the fact that small spaces (like elevators) make me queasy and nervous I was surprised to find that Buzz Aldrin's Mission to Mars : my vision for space exploration  had me wondering if I would be willing to travel to Mars. This historic pioneer in space travel (Apollo 11) did not just land on the moon and then return to retire on his laurels he advocates, to this day, for a Unified Space Vision and for the continuing quest to push the boundaries of the universe as we know it.  He would like to see humans on Mars by 2035.   Would you go?
