Submission + - Australia ignites scramjet in Earth's atmosphere

An anonymous reader writes: Australian researchers successfully tested their HyCAUSE scramjet today, confirming that it had reached a speed of Mach 10, or 10 times the speed of sound or 11,000 km/h (6,800 mph). HyCAUSE stands for the Hypersonic Collaborative Australia/United States Experiment, and it's a collaboration between the Australian Defence Science and Technology Organisation (DSTO) and the US Defense Advanced Research Projects Agency. The scramjet itself was carried aloft atop a TALOS rocket to an altitude of 530 km (330 miles). The scramjet kicked in, and it reached a top speed of Mach 10 during re-entry. In the future, scramjets could bring down flight times, with travelers going from London to Sydney in a couple of hours. They could also be used for satellite launches, and highspeed delivery. Of course, with the US military involved, there are other applications (but that's classified, so just use your imagination).
