A model of the planned Dream Chaser mini-shuttle designed by Sierra Nevada Corp. is displayed Tuesday, March 25, 2014 for a news conference by officials from Sierra Nevada and Lockheed Martin at NASA’s Michoud Assembly Facility in eastern New Orleans. The Dream Chaser is based on an old NASA design; its outline would fit on one wing of the space shuttle with room to spare. (AP Photo/Janet McConnaughey) less
