Spirit's Warming Up On Mars
Pasadena CA (SPX) Sep 25, 2008With Martian winter on the wane, Spirit is using significantly less energy to stay warm. During the winter solstice, Spirit needed 90 watt-hours to run the heater. Now, the rover uses between 30 and 40 watt-hours. The reduced demand for power, more than the slow increase in solar-array input, has freed up energy for other things. In particular, Spirit has added more images to the ... more Rock Moved By Phoenix Lander Arm 
Pasadena CA (SPX) Sep 25, 2008The robotic arm on NASA's Phoenix Mars Lander slid a rock out of the way during the mission's 117th Martian day (Sept. 22, 2008) to gain access to soil that had been underneath the rock. The lander's Surface Stereo Imager took this image later the same day, showing the rock, called "Headless," after the arm pushed it about 40 centimeters (16 inches) from its previous location. ... more After Olympics, China eyes space conquest 
Beijing (AFP) Sept 24, 2008Flushed with success after a widely applauded Beijing Olympics, China will seek this week to further burnish its image with a new chapter in its quest to conquer space. Long-time Communist Party member Zhai Zhigang is slated to become the nation's first "taikonaut" to walk in space during the Shenzhou VII mission, China's third manned space flight, which is slated to blast off Thursday night ... more Mars Polar Cap Mystery Solved 
Paris, France (ESA) Sep 23, 2008Scientists are now able to better explain why Mars's residual southern ice cap is misplaced, thanks to data from ESA's Mars Express spacecraft - the martian weather system is to blame. And so is the largest impact crater on Mars - even though it is nowhere near the south pole. Like Earth, Mars has frozen polar caps, but unlike Earth, these caps are made of carbon dioxide ice as well as ... more Growing Library Of Mars Spectrometer Images 
Pasadena CA (SPX) Sep 23, 2008A September 2008 release of 1,575 new images, such as this one, from the Compact Reconnaissance Imaging Spectrometer (CRISM) on NASA's Mars Reconnaissance Orbiter brings the number of released, high-resolution CRISM images to 4,580. This image in enhanced color from visible-light wavelengths shows light-toned rugged highland material in an area near the Martian equator. It covers an area ... more |

Pasadena CA (SPX) Sep 23, 2008NASA's Mars Rover Opportunity is setting its sights on a crater more than 20 times larger than its home for the past two years. To reach the crater the rover team calls Endeavour, Opportunity would need to drive approximately 12 kilometers (7 miles) to the southeast, matching the total distance it has traveled since landing on Mars in early 2004. The rover climbed out of Victoria Crater ... more Opportunity Playing In The Sand 
Pasadena CA (SPX) Sep 22, 2008During the past week, Opportunity performed several tests of the robotic arm to learn how to use it with a disabled shoulder joint. Having successfully completed those tests, Opportunity is moving on to investigate some bright patches of dust. Scientists hope to ascertain if the patches contain material not thoroughly analyzed in the past. On sol (Martian day) 1641 (Sept. 4, 2008) ... more HiRISE Provides Detail Of Mars Terrain That Tantalizes Explorers 
Tucson AZ (SPX) Sep 19, 2008The High Resolution Imaging Science Experiment aboard NASA's Mars Reconnaissance Orbiter, has returned more than 8,214 gigapixel-size images of the Martian surface since the start of the science phase of the mission in November 2006. HiRISE scientists released 1,005 observations of Mars made between April 26 and July 21 to NASA's mission data archive, called the Planetary Data System, and ... more Surface Water May Have Existed Far Longer On Some Parts Of Mars 
Tucson AZ (SPX) Sep 18, 2008Water may have played a role in shaping parts of the Martian landscape a billion years longer than previous studies have shown, according to a research team led by Catherine Weitz, a senior scientist with the Planetary Science Institute. Their research, to be published in "Geophysical Research Letters" and now available online, presents strong evidence that sustained and large-scale process ... more |

Pasadena CA (SPX) Sep 16, 2008Opportunity has completed one of the most fantastic scientific campaigns of the Mars Exploration Rover mission -- the interior investigation of "Victoria Crater." After spending more than 340 Martian days, known as sols -- almost one Earth year -- inside the crater, Opportunity climbed back out on sol 1634 (Aug. 28, 2008). To do so, Opportunity retraced the wheel tracks the robotic ... more NASA's Phoenix Lander In A Whirlwind 
Tucson AZ (SPX) Sep 12, 2008NASA's Phoenix Mars Lander has photographed several dust devils dancing across the arctic plain this week and sensed a dip in air pressure as one passed near the lander. These dust-lofting whirlwinds had been expected in the area, but none had been detected in earlier Phoenix images. The Surface Stereo Imager camera on Phoenix took 29 images of the western and southwestern horizon on Sept ... more Looking For Life On Mars - In A Canadian Lake 
Moffett Filed CA (SPX) Sep 12, 2008On the surface, Pavilion Lake, nestled among the peaks of Canada's Marble Range, looks like a thousand other mountain lakes. It's not unusually large or deep. It's not especially acidic, or alkaline; it's not overly salty; nor are there high concentrations of minerals dissolved in its water. Locals come here to fish, to boat, to swim, and to watch the summer clouds drift by. But underwater ... more Next Mars Soil Scoop Slated For Last Wet Lab Cell 
Tucson AZ (SPX) Sep 11, 2008The next soil sample that NASA's Phoenix Mars Lander will deliver to its deck instruments will go to the fourth of the four cells of Phoenix's wet chemistry laboratory, according to the Phoenix team's current plans. The chosen source for that sample is from the "Snow White" trench on the eastern end of the work area reachable with Phoenix's robotic arm. In July that trench yielded a ... more
