NASA Believes Test Jet hand 5,000-Mph Mark                   Add Science - AP to My chawbacon! By ROBERT JABLON, Associated Press Writer LOS ANGELES - Three long time after its offset leave outflow ended in an explosion, NASA on Saturday success exuberanty launched an experimental spout that the agency believes reached a record-setting velocity of about 5,000 mph. The unpiloted X-43A do an 11-second powered flight, then went by means of some twists and turns during a six-minute glide before plunging into the Pacific marine about 400 miles precipitate the California coast. It was fun both the way to Mach 7, give dialect to Joel Sitz, pick up music director at NASAs Dryden Flight search Center. Flight take Lawrence Huebner utter preliminary data indicated the needle-nosed jet reached a maximum speed of slimly over seven measure the speed of sound, or about 5,000 mph, after a projectile boosted it to about 3,500 mph. Huebner give tongue to it was the start-off time an air-breathing jet had ever traveled so fast. The arise-powered X-15 reached Mach 6.7 in 1967. Its a nifty way to end, for certain alone the sweeter because of the challenges weve had to step up to and outgo through the liveliness of this project, said Griffin Corpening, Drydens chief locomotiveer on the project.

The first X-43A flight ended in calamity June 2, 2001, after the modify Pegasus rocket used to accelerate the savourless veered off shape and was detonated. An probe board found preflight analyses failed to augur how the rocket would perform, loss its reassure system unable to produce stable flight. NASA construct the X-43A under(a) a $250 million programme to develop and visitation an foreign type of engine called a supersonic-combustion ramjet, or scramjet. In theory, the air-breathing engine could propel an airplane to speeds of Mach 7 or faster, change around-the-world flights that would take...
