Grasshopper is a 10-story Vertical Takeoff Vertical Landing (VTVL) vehicle that SpaceX has designed to test the technologies needed to return a rocket back to Earth intact. While most rockets are designed to burn up in the atmosphere during reentry, SpaceX's rockets are being designed to return to the launch pad for a vertical landing.
