A worker hangs portions of a parachute in preparation for an upcoming test at the Parachute Refurbishment Facility. The first stage of the new Ares I rocket and Orion spacecraft will use parachutes to return to Earth. Current tests are being performed in Arizona to make sure the designs can safely handle their intended weight. Ares I is an in-line, two-stage rocket that will transport the Orion crew exploration vehicle to low-Earth orbit. The Ares I first stage will be a five-segment solid rocket booster based on the four-segment design used for the shuttle. As with the shuttle, this booster will fall away when spent, lowered by parachute into the Atlantic Ocean where it can be retrieved for re-use. Unlike the shuttle, the booster will be flying faster, at Mach 6, when its separation from the rest of Ares I occurs. Photo credit: NASA/Kim Shiflett
