A high altitude balloon lifts a saucer-shaped test vehicle, which holds equipment for landing large payloads on Mars, at the U.S. Navy's Pacific Missile Range Facility in Kauai, Hawaii June 28, 2014. The Low-Density Supersonic Decelerator (LDSD) will be lifted to high altitudes, where a rocket will take it even higher to the top of the stratosphere at several times the speed of sound.
