From the Moon to Earth in HD 156

Lucas123 writes "The Japan Space Agency's Kaguya spacecraft is currently orbiting the moon and its equipment is being tested in preparation for its real mission to map the moon with high-definition images later this month. Almost as an afterthought, the space craft has recreated one of the most memorable photos in the history of spaceflight — an Earth-rise from lunar orbit."

AMD Announces Triple-Core Phenom Processors 334

MojoKid writes "AMD has officially announced their triple-core Phenom multi-core processor offering, suggesting a triple-threat of processors, from dual-cores to triple-cores and native quad-cores coming to market this year. While the term symmetric multi-processing (or SMP) suggests a balanced approach of multiple cores in an even number of engines working together on a single workload, AMD offers that an odd number of processors can slice at that workload just as efficiently. Time will tell how this architecture will scale amongst various multi-threaded applications and real-world usage models. AMD is definitely moving to make use of these quad-cores that don't quite make the cut by testing them fully as triple-cores and realizing some revenue, rather than throwing them away."

Photonic Laser Thruster Promises Earth to Mars in a Week 413

serutan writes "Using lasers to drive spaceships has been a subject of interest for many years, but making a photonic engine powerful enough for practical use has been elusive. Dr. Young Bae, a California physicist, has built a demonstration photonic laser thruster that produces enough thrust to micro-maneuver a satellite. This would be useful in high-precision formation flying, such as using a fleet of satellites to form a space telescope with a large virtual aperture. Scaled up, a similar engine could speed a spacecraft to Mars in less than a week."

Submission + - SETI@Home is now the World's Fastest Supercomputer

jemecki writes: I was looking through the distributed computing statistics at BOINCstats today and I noticed that SETI@Home distributed computing grid just passed 280 TeraFLOPS in computing power. The reason this is so remarkable is that the fastest supercomputer in the world Blue Gene/L ALSO operates at a sustained 280 TeraFLOPS. So while governments are busy using their supercomputers to model bombs and nuclear weapons, the geeks have put together the world's fastest computer and they're using it to look for aliens. Awesome.

Submission + - NASA Optimistic About Fuel Tank Repairs

DarkNemesis618 writes: "NASA is now optimistic Atlantis' fuel tank will be able to be repaired in Florida. Due to a freak hail storm February 26 that had golf-sized hail chunks raining down on the launchpad put several thousand dings in the foam covering the external fuel tank as well as damaging 28 tiles on Atlantis' wing. 20 of the 28 tiles have been repaired and workers have started sanding down the damaged area of the tank itself. After it was decided that Atlantis needed to return to the VAB, NASA was unsure as to whether or not the tank could be repaired. But after bringing it back and doing more extensive inspections, the tank appeared to be in good enough shape that repairs could be done on the spot and a replacement was not necessary. This will allow for Atlantis to be launched late April for its construction mission to the ISS as well as not interfering with the remaining 4 launches planned this year. If the tank needed to be replaced, Atlantis would not have launched until June at the earliest."

An Open Letter To Diebold 266

jcatcw writes "Computerworld's Rob Mitchell tells Diebold President and CEO Thomas Swidarski how to regain Diebold's reputation instead of throwing in the e-voting towel. He recommends full disclosure of all existing problems, a process for disclosure of future problems, hiring of some real professionals as CTO and as an advisory group, and public testing. 'Surely if Diebold can make a secure ATM there is no reason why it cannot make secure and reliable e-voting apparatus in which the public has confidence.'"
