Legendary "space statesman" Buzz Aldrin is a vital advocate for the continuing quest to push the boundaries of the universe as we know it.
As a pioneering astronaut who first set foot on the moon during mankind's first landing of Apollo 11--and as an aerospace engineer who designed an orbital rendezvous technique critical to future planetary landings--Aldrin has a vision, and in his new book, Mission to Mars: My Vision for Space Exploration, he plots out the path he proposes, taking humans to Mars by 2035.
