SpaceX has released a spectacular new video of its vertical-takeoff-and-landing (VTVL) reusable launch vehicle (RLV) Grasshopper. Grasshopper is the first stage of SpaceX's efforts to create a reusable space launch system that, by virtue of not wastefully dropping everything into the ocean, will massively reduce the cost of spaceflight -- like, to the point where you and I could visit outer space for less than a few months' salary.
