Charles Simonyi, the only civilian to visit the International Space Station twice, poses for a photo Tuesday, March 27, 2012, as he looks through a window of the Soyuz TMA-14 descent module that took him to the International Space Station on his second trip into space, at the Seattle's Museum of Flight's new space gallery, which is named after him. 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.
