Grasshopper Completes Highest Leap to Date
On Thursday, March 7, 2013, SpaceX’s Grasshopper doubled its highest leap to date to rise 24 stories or 80.1 meters (262.8 feet), hovering for approximately 34 seconds and landing safely using closed loop thrust vector and throttle control. Grasshopper touched down with its most accurate precision thus far on the centermost part of the launch pad. At touchdown, the thrust to weight ratio of the vehicle was greater than one, proving a key landing algorithm for Falcon 9. The test was completed at SpaceX’s rocket development facility in McGregor, Texas.
Grasshopper, SpaceX’s vertical takeoff and landing (VTVL) vehicle, continues SpaceX’s work toward one of its key goals – developing fully and rapidly reusable rockets, a feat that will transform space exploration by radically reducing its cost. With Grasshopper, SpaceX engineers are testing the technology that would enable a launched rocket to land intact, rather than burning up upon reentry to the Earth’s atmosphere.
This is Grasshopper’s fourth 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) and in December, it flew to 40 meters (131 feet). Grasshopper stands 10 stories tall and 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.
SpaceX designs, manufactures and launches the world’s most advanced rockets and spacecraft. With a diverse manifest of launches to deliver commercial and government satellites to orbit, SpaceX is the world’s fastest growing space launch company. In 2010, SpaceX became the first commercial company in history to put a spacecraft into orbit and return it safely to Earth. With the retirement of the space shuttle, the SpaceX Falcon 9 rocket and Dragon spacecraft will soon carry cargo, and one day astronauts, to and from the Space Station for NASA. Founded in 2002 by Elon Musk, SpaceX is a private company owned by management and employees, with minority investments from Founders Fund, Draper Fisher Jurvetson, and Valor Equity Partners. The company has over 3,000 employees in California, Texas, Washington, D.C., and Florida. For more information, visit spacex.com.
