As with previous tests the latest flight was conducted in McGregor, Texas. Up until now the demonstrator had flown to a height of 820 feet and included a lateral transfer of some 330 feet. In coming months SpaceX is expected to move onto tests of a larger version of the Grasshopper also dubbed by SpaceX founder Elon Musk as Falcon 9R (re-usable). Instead of a single Merlin 1D, the v1.1 successor will have nine -1Ds. Testing will be conducted at a specially constructed site at Spaceport America in New Mexico. The VTVL is designed to test the technologies needed to return a rocket back to Earth intact instead of burning up on atmospheric re-entry. The recent Falcon 9 v1.1 flight from Vandenberg AFB, Calif, also included a first attempt at slowing the first stage.
