Boeing Awarded Contract For GPS Enhancement Demonstration
St. Louis MO (SPX) Aug 11, 2008Boeing has been awarded a $153.5 million U.S. Naval Research Laboratory contract to demonstrate High Integrity Global Positioning System (GPS) technology concepts. The contract is expected to run through 2010. The High Integrity GPS effort combines satellite signals from the Iridium Low Earth Orbit telecommunications system and GPS Mid Earth Orbit navigational satellites to enhance ... more Soil Studies Continue At Site Of Phoenix Mars Lander 
Tucson AZ (SPX) Aug 11, 2008NASA's Phoenix Mars Lander has continued studies of its landing site by widening a trench, making overnight measurements of conductivity in the Martian soil and depositing a sample of surface soil into a gap between partially opened doors to an analytical oven on the lander. Phoenix's robotic arm delivered soil Thursday from a trench informally named "Rosy Red" through a narrow opening to ... more Quantum Chaos Unveiled 
Salt Lake City UT (SPX) Aug 11, 2008A University of Utah study is shedding light on an important, unsolved physics problem: the relationship between chaos theory - which is based on 300-year-old Newtonian physics - and the modern theory of quantum mechanics. The study demonstrated a fundamental new property - what appears to be chaotic behavior in a quantum system - in the magnetic "spins" within the nuclei or centers of ... more Professor Plays Vital Role In Mars Water Breakthrough 
Pasadena CA (SPX) Aug 11, 2008NASA's Phoenix Mars Lander has recently confirmed what space scientists have suspected for a long time: There is water on Mars. UT Dallas Physics Professor John Hoffman, a member of the William B. Hanson Center for Space Sciences, is at the center of the discovery. Hoffman's mass spectrometer is the system that analyzed gases from soil samples, the step needed to prove the existence ... more Chasing Dust Devils 
Tucson AZ (SPX) Aug 11, 2008"It's a bit of an art - learning how to drive across dry lake beds at great speed," says Matt Balme. "And it can be quite hairy as well." During the next three years, Balme will spend a lot of time careening across playas and other open, desert areas to better understand dust devils on Mars - how much dust they lift into the atmosphere and how this affects the martian climate. Understanding ... more |

Pasadena CA (SPX) Aug 11, 2008"Victoria Crater" continues to challenge Mars rover drivers as they try to find a location where Opportunity can do scientific studies of rocks near the "Cape Verde" cliff face. They have been trying to drive the rover to a location nicknamed "Nevada" after a rock shaped somewhat like the state of Nevada. Getting there, however, has been challenging. After attempting unsuccessfully to ... more Mercury Flyby Data Delivered To Planetary Data System 
Baltimore MD (SPX) Aug 11, 2008Data from MESSENGER's first flyby of Mercury have been released to the public by the Planetary Data System (PDS), an organization that archives and distributes all of NASA's planetary mission data. "This delivery, while not the first for the MESSENGER mission, represents a significant milestone," says MESSENGER Mission Archive Coordinator Alan Mick, of the Johns Hopkins University Applied ... more Computer Simulations Show How Special The Solar System Is 
Evanston IL (SPX) Aug 11, 2008Prevailing theoretical models attempting to explain the formation of the solar system have assumed it to be average in every way. Now a new study by Northwestern University astronomers, using recent data from the 300 exoplanets discovered orbiting other stars, turns that view on its head. The solar system, it turns out, is pretty special indeed. The study illustrates that if early ... more 'Cloud computing' trend heightens privacy risks 
Las Vegas (AFP) Aug 8, 2008A US military computer science professor on Friday warned that a trend to push software into the "clouds" exacerbates privacy risks as people trust information to the Internet. Websites routinely capture data that can reveal pictures of users' lives, US military academy professor Greg Conti told an audience at the annual DefCon hackers gathering in Las Vegas. The danger is being heightened ... more ITC Judge Finds SiRF Infringes Six Broadcom GPS Patents 
Washington DC (SPX) Aug 11, 2008Broadcom has announced that a U.S. International Trade Commission (ITC) judge ruled that products of SiRF Technology Holdings infringe six patents related to improving global positioning system (GPS) processing and sensitivity. The patents are held by Global Locate, Inc., a wholly-owned subsidiary of Broadcom. The Initial Determination containing the infringement ruling followed a trial ... more |

Las Vegas, Nevada (AFP) Aug 8, 2008Hackers turned computer security specialists accuse Google of setting users up for online disasters by letting them personalize home pages with applications that could be tainted. Software that hackers can trick people into installing on "iGoogle" home pages can track users' activities and control their machines, SecTheory chief executive Robert Hansen showed AFP on Friday. "I could ... more French reporters booted from US computer security conference 
Las Vegas, Nevada (AFP) Aug 7, 2008Reporters from an online French magazine were booted from the world's premier computer security conference Thursday after reportedly hacking a press room network and stealing peers' passwords. An accused trio from Global Security Magazine said they intended to teach reporters about how easily Internet transmissions could be intercepted while covering the Olympics in China, according to ... more ATK Conducts Successful AARGM Flight Test 
Minneapolis MN (SPX) Aug 11, 2008Alliant Techsystems, the U.S. Navy, and the Italian Air Force successfully completed another challenging missile firing of the AGM-88E Advanced Anti-Radiation Guided Missile (AARGM) at the Naval Air Weapons Station China Lake on August 3, 2008. The missile test firing was the first of two "Operational Assessment" firings supporting Milestone C Low Rate Initial Production (LRIP) decision ... more Canada says science backs up its Arctic claim 
Ottawa (AFP) Aug 9, 2008Canada says it has scientific proof of its territorial claims over a vast portion of the Arctic, amid debate between northern nations over sovereignty in the oil-rich region. Natural Resources Minister Gary Lunn said Friday joint research with Denmark had found that the undersea Lomonosov Ridge is attached to the North American and Greenland plates, directly challenging a Russian claim. ... more Patagonian Glacier Yields Clues Of Global Climate Change 
Paris, France (SPX) Aug 11, 2008A better understanding of climate variations at planetary scale is one of climate scientists' crucial concerns. Stable water isotope analysis, the chemistry of ice cores taken from the Arctic and Antarctic polar ice caps and of air bubbles trapped in them now allow a chronology to be drawn up of the climate changes that took place over the past 800 000 years. However, those data, collected ... more
