Images of Chi Cygni reveal Sol's fate Cambridge MA (SPX) Dec 16, 2009 About 550 light-years from Earth, a star like our Sun is writhing in its death throes. Chi Cygni has swollen in size to become a red giant star so large that it would swallow every planet out to Mars in our solar system. Moreover, it has begun to pulse dramatically in and out, beating like a giant heart. New close-up photos of the surface of this distant star show its throbbing motions in unprecedented detail. "This work opens a window onto the fate of our Sun five billion years from now, when it will near ... read more |

The Meandering Channels Of Mars Moffett Field CA (SPX) Dec 11, 2009 The surface of Mars is littered with channels that appear to be the work of ancient water flows.

Channels can be carved by lava, wind and glaciers, but these processes can't explain all the features on Mars. "We've gotten over the hump and can now agree that water flowed on the martian surface in ... more Life On Mars Theory Boosted By New Methane Study London, UK (SPX) Dec 09, 2009 Scientists have ruled out the possibility that methane is delivered to Mars by meteorites, raising fresh hopes that the gas might be generated by life on the red planet, in research published in Earth and Planetary Science Letters. Methane has a short lifetime of just a few hundred years on Mars because it is constantly being depleted by a chemical reaction in the planet's atmosphere ... more Rear Wheel Trouble Continues For Mars Rover Spirit Pasadena CA (JPL) Dec 11, 2009 Results of diagnostic tests on Spirit's right-rear wheel on Sol 2109 (Dec. 8, 2009) continue to indicate a troubled wheel, which may leave the rover with only four operable wheels. The Sol 2109 plan included a check of the grind motor of Spirit's rock abrasion tool (RAT) because it shares the same motor controller as the right-rear wheel.

Opportunity Investigates 'Marquette' And 'Islington Bay' Pasadena CA (SPX) Dec 08, 2009 Opportunity Status for sol 2076-2079: Opportunity has been investigating the rock known as "Marquette Island." On Sol 2076 (Nov. 25, 2009), the robotic arm (IDD) placed the Moessbauer (MB) spectrometer on a rock target called "Islington Bay" for a long, multi-sol integration. With the temporary loss of relay operations for a few sols because of the Odyssey spacecraft safe-mode, Opportunity ... more Spirit's Diagnostic Wheel Tests Continue Spirit Status for sol 2096-2099: Spirit's extrication from her embedded location at Troy on the west side of Home Plate has been complicated by a recurring stall condition with the right rear wheel. After diagnostic tests on Sol 2095 (Nov. 24, 2009), indicated a freely moving wheel, another two-step drive with 5 meters (16 feet) of wheel spin was commanded on Sol 2099 (Nov. 28, 2009). ... more Astrosat All Set To Be Launched Next Year Bangalore, India (PTI) Dec 07, 2009 India's first science satellite Astrosat is all set to be launched next year, former chairman of Indian Space Research Organisation (ISRO) Madhavan Nair said. One more satellite 'Aditya' to study Sun's coronal mass ejection (CME) would be launched in two years while the science mission to planet Mars by 2013, Nair said, addressing a galaxy of scientists from India and abroad and the ... more |
