Engine Helps Satellites Blast Off With Less Fuel
Atlanta GA (SPX) Feb 23, 2007Georgia Tech researchers have developed a new protoype engine that allows satellites to take off with less fuel, opening the door for deep space missions, lower launch costs and more payload in orbit. The efficient satellite engine uses up to 40 percent less fuel by running on solar power while in space and by fine-tuning exhaust velocity. Astronauts Urged To Take Up Skiing Ahead Of Lunar Missions 
San Francisco (AFP) Feb 23, 2007Astronauts could be trained to cross-country ski across the surface of the moon as preparations for the next generation of lunar missions take shape, a conference heard Saturday. The National Aeronautics and Space Administration (NASA) announced plans last year to build a base on the moon by 2020, hoping to use the lunar outpost as a launchpad for exploring the solar system in future generations. ISS Crew Complete Hour Space Walk As Next Shuttle Crew Conduct Dry Countdown 
Moscow (AFP) Feb 22, 2007Two astronauts at the International Space Station (ISS) did a six-hour space walk on Thursday to repair an antenna on a refuelling vessel, Russia's space flight control centre said. "The American astronaut Michael Lopez-Alegria and his Russian colleague Mikhail Tyurin opened the station's airlock at 13:27 Moscow time (10:27 GMT) and left the station," a spokesman at the centre, Valery Lyndin, told AFP. |
Absence Of Water In Distant Exo Planet Atmosphere Surprises Astronomers
Cambridge MA (SPX) Feb 23, 2007A team of astronomers led by Carl Grillmair (Spitzer Science Center) and David Charbonneau (Harvard-Smithsonian Center for Astrophysics) announced today that they have directly measured the first spectrum from a known planet orbiting a distant star. Two other teams made a similar measurement of a different extrasolar planet. Taken together, this pioneering work opens a new field of planetary exploration, allowing astronomers to directly analyze the atmospheres of worlds beyond our solar system. Sol Sister 
Flagstaff AZ (SPX) Feb 23, 2007For the first time, astronomers have collected and analyzed a long-term set of activity and brightness measurements of a "solar twin." A team from Lowell Observatory and Tennessee State University recently announce that the close solar analog, 18 Scorpii, exhibits brightness changes over the course of its activity cycle that are nearly identical to the Sun's. Iridium Launches Industry-First Network Quality Guarantee 
Bethesda MD (SPX) Feb 23, 2007Iridium Satellite announces a new network quality guarantee program for customers with a promise of 100 percent satisfaction with Iridium service. The "Iridium Network Quality Guarantee" promises credits of up to 100 minutes of airtime, as well as three months free subscription fees, if the Iridium network fails to complete properly initiated voice calls from customers' new Iridium handsets. |

Vivid On-Line Videos Demonstrate SuperBot Progress
Los Angeles CA (SPX) Feb 23, 2007Wei-Min Shen of the University of Southern California's Information Sciences Institute recently reported to NASA significant progress in developing "SuperBot," identical modular units that plug into each other to create robots that can stand, crawl, wiggle and even roll. He illustrated his comments with striking video of the system in action, video now posted on line. Opportunity Continues To Characterize Crater 
Pasadena CA (JPL) Feb 23, 2007Opportunity is healthy and is currently driving on the promontory "Cabo Corrientes" where its cameras imaged the north face of "Bahia Blanca" cliff walls. The rover is currently driving to another spot in order to image "Cape Desire." February 9th, 2007, was the first day of spring in the southern hemisphere of Mars. New Observations Show Sun-Like Star In Earliest Stage Of Development 
Boulder CO (SPX) Feb 23, 2007Members of a research team led by the University of Colorado at Boulder have used NASA's Chandra X-ray Observatory to peer at the embryo of an infant star in the nearby Eagle Nebula, which they believe may someday develop into a virtual twin of Earth's sun. The object, known as an evaporating gas globule, or EGG, has the same mass as the sun and appears to be evolving in a violent environment much like the one believed to have produced Earth's sun, said researcher Jeffrey Linsky of JILA, a joint institute of CU-Boulder and the National Institute of Standards and Technology. |
Indian Engineers Key In Development Of New Intel Super Chip
Bangalore (AFP) India, Feb 22, 2007Half the work on a new Intel chip, a fingernail-sized device that offers supercomputer performance, was done by engineers at its India research centre, the company said Thursday. A 20-member Indian team led by Vasantha Erraguntla, a 15-year Intel veteran who relocated to Bangalore in June 2004 from the US, contributed to the project in terms of the logic, circuit and physical design, Intel India said. First X-Ray Detection Of A Colliding-Wind Binary Beyond Milky Way 
Paris, France (ESA) Feb 23, 2007Imagine two stars with winds so intense that they eject an Earth's worth of material roughly once every month. Next, imagine those two winds colliding head-on. Such titanic collisions produce multimillion-degree gas, which radiates brilliantly in X-rays. Astronomers have conclusively identified the X-rays from about two-dozen of these systems in our Milky Way. But they have never seen one outside our galaxy - until now. Out-Of-This-World Ride In NASA's 14th Annual Great Moonbuggy Race 
Huntsville AL (SPX) Feb 23, 2007It's no ordinary driving test and they won't have to parallel park, but future astronauts will learn what it will take to some day drive on the surface of the moon. NASA is looking for the world's best moonbuggy drivers who can also create and build their own original "lunar rover." |
