Great View of Grasshopper Flight
On June 14, SpaceX's Grasshopper flew 325 m (1066 feet)--higher than Manhattan's Chrysler Building--before smoothly landing back on the pad. Grasshopper is a 10-story Vertical Takeoff Vertical Landing (VTVL) vehicle designed to test the technologies needed to return a rocket back to Earth intact. It will also not burn up on reentry back to Earth.
