Elon Musk's space ferries will one day require nothing so prosaic as parachutes to soften their landings. Instead, SpaceX's latest 'Dragon' design will rely totally on rocket boosters for the final leg of its descent. In fact, take that notion and triple it: it's intended that each of the Dragon's three sub-sections will be able to return to earth separately under boost power, making the system 100 percent reusable. Check out the slick animation after the break and then see this for a dose of reality.
