Dark, narrow streaks on Martian slopes such as these at Hale Crater are believed to be formed by seasonal flow of water.  The streaks are roughly the length of a football field. Photo courtesy of: NASA/JPL-Caltech/Univ. of Arizona. Scientists reported this morning that there is compelling evidence that liquid water exists on the surface of present-day Mars. The announcement was made based on new findings from NASA’s Mars Reconnaissance Orbiter (MRO) .Using an imaging spectrometer o ...
  If you wait around long enough sometimes reality gets closer to science fiction. In the 1982 film “Firefox” Clint Eastwood plays an American pilot assigned to steal a highly advanced Soviet fighter aircraft which, among other things, uses a helmet that allows the pilot to control weapons launch through thought. Recently, Rockwell Collins introduced the Gen III Helmet Mounted Display System (HMDS) for the F-35 aircraft that allows pilots in aircraft equipped with the system to ...
C-130 Hercules carrying a tactical laser When three top Air Force officers speaking separately at the same conference all say they expect the service to demonstrate airborne laser weapons by the end of this decade it wouldn’t be wise to bet against it.   The general officers were Maj. Gen. Thomas Masiello, commander of ARFL, the U.S. Air Force Research Laboratory, Lt. Gen. Bradley Heithold, head of the Air Force Special Operations Command and General Hawk Carlisle, head of Air C ...
The low cost of digital imaging devices has allowed them to become popular consumer products.  This low cost is made possible by leveraging a mature processing infrastructure and the ability to fabricate complete focal plane arrays (FPAs) at the wafer scale.  A similar trend is occurring on a smaller scale with thermal imaging technologies.  Microbolometers that are sensitive in the long wave infrared (LWIR) spectrum and are used as a detector in a thermal camera are also manufact ...
Combining data obtained from two powerful instruments aboard NASA's Mars Reconnaissance Orbiter (MRO), researchers at the University of Arizona's Lunar and Planetary Laboratory (LPL) determined why the crater shown above is terraced — not bowl shaped, like most craters of this size. Terraces can form when there are layers of different materials in the planet’s subsurface, such as dirt, ice or rock. When the crater is forming, the shock wave from an object hitting a planet’s su ...
The Bloodhound SSC land speed record racing car will make its world debut at East Wintergarden, Canary Wharf, London on Thursday, 24 September before going on public display on Friday and Saturday the 25th and 26th of September from 9am to 5pm. Bloodhound SSC is a jet- and rocket-powered car designed to reach 1,000 mph on land. It has a slender body of approximately 13.4m in length with two front wheels within the body and two rear wheels mounted externally within wheel fairings. It weighs 7.5 t ...
