Pasadena CA (JPL) Jan 03, 2009 - NASA rovers Spirit and Opportunity may still have big achievements ahead as they approach the fifth anniversaries of their memorable landings on Mars.
Paris, France (SPX) Dec 22, 2008 - Observations made with the OMEGA imaging spectrometer onboard Mars Express reveal very strong signatures of sulfates and ferric oxides in Aram Chaos. Detailed morphological analyses indicate that the concentration of ferric oxides in this region results from the alteration of a sulfate rich sedimentary formation resting on the floor of the crater.
Tower, Minn. (UPI) Dec 22, 2008 - Scientists could learn about Martian water life by plumbing a spring in an iron ore mine in Minnesota's Iron Range, University of Minnesota researchers say.
Tucson AZ (SPX) Dec 19, 2008 - As scientists search for life on Mars, they should take a close look at rock varnish, according to a paper in the current issue of the Journal of Geophysical Research.
Boulder CO (SPX) Dec 17, 2008 - Picture a ball. It's an ordinary ball in every way except that it is roughly 4,300 miles in diameter and is moving through the cold of space some 35 million miles from Earth, and hurtling around the sun in just less than two Earth years. This is Mars.
Pasadena CA (SPX) Dec 16, 2008 - The Martian arctic soil that NASA's Phoenix Mars Lander dug into this year is very cold and very dry. However, when long-term climate cycles make the site warmer, the soil may get moist enough to modify the chemistry, producing effects that persist through the colder times.
Paris, France (ESA) Dec 12, 2008 - The final four Europeans who are set to take part in a 105-day simulated Mars mission were presented to the media in Paris today. From March next year, two of the group will join four Russian participants inside an isolation facility in Moscow.
Paris, France (ESA) Dec 12, 2008 - Data and images from Mars Express suggest that several Light Toned Deposits, some of the least understood features on Mars, were formed when large amounts of groundwater burst on to the surface. Scientists propose that groundwater had a greater role in shaping the martian surface than previously believed, and may have sheltered primitive life forms as the planet started drying up.
Pasadena CA (SPX) Dec 12, 2008 - NASA's Mars Reconnaissance Orbiter has completed its primary, two-year science phase. The spacecraft has found signs of a complex Martian history of climate change that produced a diversity of past watery environments.
Pasadena CA (SPX) Dec 09, 2008 - The High Resolution Science Imaging Experiment, or HiRISE, team based at The University of Arizona have released 362 three-dimensional images of Mars taken by the HiRISE camera on NASA's Mars Reconnaissance Orbiter.
Beijing (RIA Novosti) Dec 08, 2008 - China will send a space probe to Mars with Russia's assistance in October 2009, a Chinese newspaper said on Friday.
Paris, France (ESA) Dec 08, 2008 - March 2009 will see two European participants entering a set of modules at the Institute of Biomedical Problems (IBMP) in Moscow. Together with four Russian participants, they will be sealed inside these isolation chambers for 105 days.
Pasadena CA (SPX) Dec 05, 2008 - Researchers at the California Institute of Technology (Caltech) and their colleagues have found evidence of ancient climate change on Mars caused by regular variation in the planet's tilt, or obliquity. On Earth, similar astronomical forcing of climate drives ice-age cycles.
Washington DC (SPX) Dec 05, 2008 - NASA's Mars Science Laboratory will launch two years later than previously planned, in the fall of 2011. The mission will send a next-generation rover with unprecedented research tools to study the early environmental history of Mars.
Moffett Field CA (SPX) Dec 05, 2008 - The possibility of life on Mars has been debated almost since the invention of the telescope-annual growth and shrinkage of the martian ice caps and seasonal changes in color were observed by astronomers such as Herschel and Whewell in the 18th and 19th centuries.
San Francisco (AFP) Dec 5, 2008 - If the Phoenix Lander comes back to life on Mars, Twitter users could be among the first to know.
