This image provided by NASA was taken on Sunday, July 31, 2011, when Expedition 28 astronaut Ron Garan aboard the International Space Station looked out his window, this is what he saw: the moon. And, he saw it 16 times. For Garan and the rest of the station crew, this extraordinary event is a daily occurrence. Since the station orbits the Earth every 90 minutes, each day the crew experiences this about 16 times a day. (AP Photo/NASA - Ron Garan)
