MarkWhittington writes: "Sometime in the fall of 2010 the space shuttle will launch on its last mission. In the early Spring of 2015, barring unforeseen delays, the Orion space craft will become operational, available to take crews and supplies to the International Space Station. This constitutes a gap of four and a half years during which the United States will not be able to fly its own astronauts into space. That worries folks at NASA, members of Congress, and others concerned with the course of the US civil space program."
