Lockheed Martin supersonic jet hits the wind tunnel – in model form

Last March, NASA announced that as part of its New Aviation Horizons initiative, Lockheed Martin had been chosen to develop a manned demonstrator aircraft called the Quiet Supersonic Technology (QueSST) X-plane. It would be used to test technologies that would make commercial supersonic aircraft quiet enough to fly over land. Eleven months later, Lockheed and the agency are ready to take the next step as a nine-percent scale model starts wind tunnel tests at the Glenn Research Center in Cleveland.

Alaska Gets 'Artificial Aurora' As HAARP Antenna Array Listens Again

Freshly Exhumed quotes Hackaday: The famous HAARP antenna array is to be brought back into service for experiments by the University of Alaska. Built in the 1990s for the US Air Force's High Frequency Active Auroral Research Program, the array is a 40-acre site containing a phased array of 180 high-frequency antennas and their associated high-power transmitters. Its purpose is to conduct research on charged particles in the upper atmosphere, but that hasn't stopped an array of bizarre conspiracy theories. A university space physics researcher will actually create an artificial aurora starting Sunday (and continuing through Wednesday) to study how yjr atmosphere affects satellite-to-ground communications, and "observers throughout Alaska will have an opportunity to photograph the phenomenon," according to the University. "Under the right conditions, people can also listen to HAARP radio transmissions from virtually anywhere in the world using an inexpensive shortwave radio."
