TEXT: In this Tuesday, March 27, 2012, photo, Charles Simonyi, the only civilian to visit the International Space Station twice, poses for a photo next to a space suit similar to the one he once wore at the Seattle's Museum of Flight's new space gallery, which is named after him, in Seattle. The Microsoft billionaire is still obsessed with space, but has no plans to take a third trip, instead he's focused on publishing a physics book written by his father and continuing to work with the museum.
