NASA Chief, Astronaut Office, Johnson Space Center Peggy Whitson, center, STS-135 Astronauts, Rex Walheim, left, and Commander Chris Ferguson are seen as the entire crew plays a traditional card game at the NASA Kennedy Space Center Operations and Checkout Building prior to them leaving for the launch pad, on Friday, July 8, 2011 in Cape Canaveral, Fla. The point of the game is that the commander must use up all his or her bad luck before launch, so the crew can only leave for the pad after the commander loses. The launch of Atlantis, STS-135, is the final flight of the shuttle program, a 12-day mission to the International Space Station. Photo Credit: (NASA/Jerry Ross)
