PITTSBURGH (NewsRadio 1020 KDKA) – Buzz Aldrin knows a thing or two about space. As the second man to step on the moon behind Neil Armstrong, he has a unique perspective on space exploration, and his new book, “Mission to Mars,” Aldrin lays out his goals for the space program and how he believes we can get humans to Mars by the 2030’s.

“There’s always been a human trait to want to look over the other hill and see what’s on the other side,” says Aldrin. “There is a great opportunity for the history of the humanity on the Earth to make this one giant leap to establish a permanence on another planet.”
