New Materials Designed To Deal With Hypersonic And Supersonic Hot StuffBrisbane, Australia (SPX) Dec 28, 2009 University of Queensland researchers are testing new materials to withstand the extreme heat experienced by hypersonic vehicles in flight so they can fly for substantially longer. Previous Australian experimental flight tests of scramjets, a type of very fast jet engine, have not lasted longer than five seconds. The tests, conducted at Woomera in South Australia over the past eight years, have used scramjet engines made of conventional materials which have problems with extreme heat including melting, and are not designed for re-use. ... read more |

Hundreds of millions of objects will populate its vast catalog, including da ... more  
Washington (AFP) Dec 27, 2009While it got off to a rocky start with the overhyped Y2K bug and dotcom bubble, the era dubbed the "Digital Decade" by Microsoft's Bill Gates has turned out to be a dizzying period of innovation. "It's been an amazingly vibrant decade for the Internet and for digital things in general," said John Abell, New York bureau chief of Wired magazine, which has chronicled the technological leaps and bounds of the past 10 years. "People simply don't exist in a non-digital world at all," Abell told AFP. "Even grandmothers and Luddites all have tools and devices - even if they don't realize they're using them - which connect them to a digital world." ... more |

Pasadena CA (JPL) Dec 25, 2009Spirit's drive on Sol 2120 (Dec. 19, 2009) included commands for using all six wheels. However, the right-front wheel rotated less than 2 degrees and the right-rear wheel did not rotate at all. The other four wheels completed enough rotations to drive about 10 meters (33 feet), but produced no measurable forward motion by the rover. The rover team plans to command further driving this week while continuing to assess the possibility of getting more motion from the right-front wheel. ... more
