NASA's X-43A research vehicle screamed into the record books again Tuesday, demonstrating an air-breathing engine can fly at nearly 10 times the speed of sound. Preliminary data from the scramjet-powered research vehicle show its revolutionary engine worked successfully at nearly Mach 9.8, or 7,000 mph, as it flew at about 110,000 feet.
The flight will "help us advance the Vision for Space Exploration, while helping to advance commercial aviation technology," NASA Administrator Sean O'Keefe said. |
