Instantly in at number one as my favourite drone footage, this filming does not show bits of leg or propeller is not GoPro bent out of shape and pans up beautifully and holds the desired shot. For once I am glad they left the sound recording running to catch the noise of the blast off. Top banana. Make sure you watch it in hi res.
SpaceX’s Grasshopper flew 325 m (1066 feet)–higher than Manhattan’s Chrysler Building–before smoothly landing back on the pad. For the first time in this test, Grasshopper made use of its full navigation sensor suite with the F9-R closed loop control flight algorithms to accomplish a precision landing. Most rockets are equipped with sensors to determine position, but these sensors are generally not accurate enough to accomplish the type of precision landing necessary with Grasshopper.
Previous Grasshopper tests relied on the other rocket sensors but for this test, an additional, higher accuracy sensor was in the control loop. In other words, SpaceX was directly controlling the vehicle based on new sensor readings, adding a new level of accuracy in sensing the distance between Grasshopper and the ground, enabling a more precise landing.
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. While most rockets are designed to burn up on atmosphere re entry, SpaceX rockets are being designed not only to withstand re entry, but also to return to the launch pad for a vertical landing. The Grasshopper VTVL vehicle represents a critical step towards this goal.
