An auction is now underway for hundreds of rare collectibles, autographed photos and NASA gear… most of it donated by astronauts and engineers to the American Space Museum in Titusville. The money raise will be used to keep the museum open and to fund educational programs there. One of the items up for bid is a photo autographed by the second human being to ever walk on the moon, Buzz Aldrin. The photo is estimated to sell for about $600 in the auction. Some items have a starting bid of just $20. Check with the museum for details.
