“What are you going to do with astronauts who first reach the surface of Mars and then turn around and rocket back home-ward? What are they going to do, write their memoirs? Would they go again? Having them repeat the voyage, in my view, is dim-witted. Why don't they stay there on Mars?”

American former astronaut, aeronautical engineer, and fighter pilot

Buzz Aldrin is an American former astronaut, aeronautical engineer, and fighter pilot. He is known for being the second person to walk on the Moon, following mission commander Neil Armstrong. Aldrin served as the pilot of NASA’s Gemini 12 mission in 1966, during which he made three spacewalks. He later flew as the Lunar Module Eagle pilot on Apollo 11 in 1969. He is now the last surviving member of that crew and the oldest living astronaut.
