 Washington (AFP) Nov 23, 2009 
A network of valleys discovered on Mars show that the red planet was likely once covered by a vast ocean that fed a humid, rainy climate, according to research published Monday. Debate has raged for decades over whether Martian valleys resulted from water erosion - caused by humidity and rainfall - or through groundwater-sapping erosion, which can happen in cold and dry conditions. ... read more
Pasadena CA (SPX) Nov 24, 2009Spirit experienced a wheel stall with the right-rear wheel during the second step of a two-step drive on Sol 2092 (Saturday, Nov. 21). This is not the same wheel that stalled on Sol 1899 (May 6), the left-middle wheel. On Sol 2092, the right-rear wheel did not experience a hard stall like what was seen on Sol 1899. Instead, it stalled because the wheel's progress fell behind the ... more

Pasadena CA (SPX) Nov 18, 2009Impact craters on Mars are kind of neat. Many of them look very different than impact craters seen on Earth's moon or Mercury. Fresh lunar and Mercurian craters have ejecta blankets that look a bit rough near the crater rims; around larger craters, long rays or chains of secondary craters radiate away from the crater rims. Some Martian craters are similar to these craters, but Mars also ha ... more 
Pasadena CA (SPX) Nov 18, 2009Spirit is preparing to attempt extrication from her embedded location at "Troy" on the west side of "Home Plate." The project was successful in reformatting Spirit's on-board flash memory file system on Sol 2083 (Nov. 11, 2009). The rover is now again using the non-volatile flash file system for telemetry storage. On Sol 2078 (Nov. 6, 2009), Spirit straightened her wheels in preparat ... more 
Pasadena CA (SPX) Nov 18, 2009NASA and Microsoft Corp. of Redmond, Wash., have collaborated to create a Web site where Internet users can have fun while advancing their knowledge of Mars. Drawing on observations from NASA's Mars missions, the "Be a Martian" Web site will enable the public to participate as citizen scientists to improve Martian maps, take part in research tasks, and assist Mars science teams studying da ... more |

Pasadena CA (SPX) Nov 04, 2009Opportunity has been making good progress driving. After completing a survey of meteorites recently, Opportunity has turned south around the point of a large ripple field. Eventually, the rover will resume heading east towards Endeavour crater. The rover drove southward on sols 2043, 2045, 2047, 2048 and 2049 (Oct. 22, 25, 27, 28 and 29, 2009), totaling over 280 meters (918 feet). ... more 
Huntsville AL (SPX) Nov 02, 2009If you found your grandmother's diary, tattered and dust covered, up in the attic, would you read it? Of course you would. Granny was a pistol! Brush off the dust, open up the little book, and foray into her lively and interesting past. Dust cloaks some fascinating tales in other places, too. NASA scientists will soon brush the dust off some Martian rocks that are practically bursting ... more 
Pasadena CA (SPX) Nov 02, 2009Until Oct. 24, NASA's Mars Exploration Rover had gone more than six months without an episode of amnesia-like symptoms like those that appeared on four occasions earlier this year. In these amnesia events, Spirit fails to record data from the day's activities onto the type of computer memory - non-volatile "flash" memory - that can retain the data when the rover powers down for its energy ... more |
