Astronaut Buzz Aldrin will take one quick step for mankind on the 10th season of the show. Being the second person to ever walk on the moon, the 80-year-old is working hard to go down in the history books once again as the oldest winner of DWTS. Paired up with dancing diva Ashley Costa, the scientist, inventor, and best-selling author is setting aside his retirement to see if he's still got the magic. "Living on Air Force retirement and Social Security, I'm forced to go out and sing for my supper quite a bit," Aldrin admits to Zap2It. Well, with the nation forever in awe of his moonwalk, this legend shouldn't have to worry about getting votes!
