SpaceX Grasshopper Flies High

by Nancy Atkinson on April 23, 2013

SpaceX’s Grasshopper flew 250 meters (820 feet) straight up, tripling the height flown on its previous leap. The video provides a great overhead view from SpaceX’s hexacopter.

Via Twitter, SpaceX CEO Elon Musk said the Grasshopper was able to remain steady in its flight even on a windy day, hover and then land.

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.

This is Grasshopper’s fifth in a series of test flights, with each test demonstrating exponential increases in altitude. Last September, Grasshopper flew to 2.5 meters (8.2 feet), in November, it flew to 5.4 meters (17.7 feet), in December, it flew to 40 meters (131 feet), and then 80.1 meters (262.8 feet) in March.

Grasshopper consists of a Falcon 9 rocket first stage tank, Merlin 1D engine, four steel and aluminum landing legs with hydraulic dampers, and a steel support structure.
