Dancing With the Astronauts

Howard asked Buzz Aldrin what he thought of Nicole Scherzinger, one of his fellow 'Dancing with the Stars' contestants, and Buzz said she was the most attractive on the show: "#1 with me. She came from was one of the appreciated sidelights of being a part of all that."

Pleased with Buzz's candid statements, Howard pressed further into his sex life. Buzz laughed: "As you move on in age, you're either dealing with a little blue pill or a little yellow pill."

Buzz Hopes for a Mission to Mars

Buzz told the crew that he hoped NASA would send a manned mission to Mars next: "We sure have no business going back to the Moon...there may be some good science--some good commercial developments--but I don't know what they are."

On his way out, Buzz took issue with being called a 'former astronaut,' as, in his words: "Once an astronaut, always an astronaut."
