Buzz Aldrin speaks out as 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 this book he plots out the path he proposes, taking humans to Mars by 2035. --
