Pasadena CA (JPL) Dec 18, 2009 - Spirit's right-front wheel, which had stopped operating in March 2006, revolved with apparently normal motion during the first three of four driving segments on Sol 2117 (Wednesday, Dec. 16) but stopped early in the fourth segment of the drive.
Moffett Field CA (SPX) Dec 18, 2009 - Certain environments on Earth that host life are very similar to places on Mars and other terrestrial planets, scientists have found. So if life can exist here, why not there?
Tucson AZ (SPX) Dec 16, 2009 - Catherine Weitz, a senior scientist at the Tucson-based Planetary Science Institute, has reported new evidence for multiple, water-related geologic processes on Mars.
London (UPI) Dec 15, 2009 - Imperial College London scientists say they have ruled out the possibility that methane is delivered by meteorites into Mars' atmosphere.
Moffett Field CA (SPX) Dec 14, 2009 - For the very first time, the Martian moons Phobos and Deimos have been caught on camera together. ESA's Mars Express orbiter took these pioneering images last month. Apart from their 'wow' factor, these unique images will help the HRSC team validate and refine existing orbit models of the two moons.
Pasadena CA (SPX) Dec 14, 2009 - Opportunity Status for sol 2080-2090: On Sol 2086 (Dec. 6, 2009), the rover backed away and then drove about 5 meters (16 feet) around Marquette Island to image other parts of the rock.
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. Indeed, some of these channels meander back and forth like slow-moving streams on our planet. Channels can be carved by lava, wind and glaciers, but these processes can't explain all the features on Mars.
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.
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.
Pasadena, Calif. (UPI) Dec 9, 2009 - NASA technicians say they have taken the Mars Reconnaissance Orbiter out of the precautionary safe mode it has been in since August.
Pasadena, Calif. (UPI) Dec 8, 2009 - NASA engineers attempting to free the Mars rover Spirit from loose Martian sand since April say the results of their attempts so far are not encouraging.
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.
- 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.
Huntsville AL (SPX) Dec 04, 2009 - Homer's Iliad tells the story of Troy, a city besieged by the Greeks in the Trojan War. Today, a lone robot sits besieged in the sands of Troy while engineers and scientists plot its escape.
Houston TX (SPX) Dec 03, 2009 - Using more advanced analytical instruments now available, a Johnson Space Center research team has reexamined the 1996 finding that a meteorite contains strong evidence that life may have existed on ancient Mars.
Pasadena CA (SPX) Dec 03, 2009 - NASA's Mars Odyssey orbiter put itself into a safe standby mode on Saturday, Nov. 28, and the team operating the spacecraft has begun implementing careful steps designed to resume Odyssey's science and relay operations within about a week.
