Apollo XI and Gemini 12 astronaut and Korean War fighter pilot Buzz Aldrin hosted an #AskBuzz eventย at Twitter headquarters today. What most people seemed to want to know was where to get one of those cool โ€œTotal Recallโ€ inspired โ€œGet your ass to Marsโ€ T-shirts that Aldrin was sporting. (Just FYI, theyโ€™re available at his website.)

Aldrin answered several questions in exchange for a favor to be asked later.

The favor? Provide some suggestions on how to get the next president to commit to a mission to Mars by the 50th anniversary of the moon landing.
