Trouble with a control fin on the sleek, scramjet-powered aircraft puts an abrupt and early end to the Air Force's attempt at a Mach 6 flight.
One day we might be able to fly from Los Angeles to New York in 45 minutes. Pratt & Whitney Rocketdyne is developing technology that could make hypersonic flight possible.
Over at the Skunk Works, aircraft designers are hard at work cooking up a hypersonic scion to the legendary SR-71, the superspeedy recon jet of the Cold War.
The new lens, part of Sigma's high-end "art" product line, will ship in November, but its true competitiveness won't be known until Sigma reveals its price.
The new XS-1 program wants designs for satellite-toting flying machines that are fast (hypersonic, even), cheap, and reusable -- on a one-day turnaround, no less.
The test, in which the Falcon 9 test rig was able to take off, fly to an altitude of 250 meters, and then move laterally 100 meters, is a crucial step in the program's progress.
The U.S. Army's Advanced Hypersonic Weapon can travel about five times the speed of sound and strike anywhere on Earth in less than an hour.
In June 1943, Lockheed made a bold pitch to the U.S. Army that it could build a jet fighter, and build it fast. Since then, the Skunk Works has conjured up the U-2, the SR-71, the F-117, and more, and it's still going strong.
The accomplishment marks the longest flight for the $300 million X-51A technology demonstration program and, according to the Air Force and Boeing, the longest scramjet-powered hypersonic flight ever.
During a keynote address in which the SpaceX and Tesla founder talked about both his companies, the highlight was probably a video showing a Grasshopper rocket landing like a helicopter.
