Thanks to data from ESA's Mars Express mission, combined with models of the Martian climate, scientists can now suggest how the orbit of Mars around the Sun affects the deposition of water ice at the Martian South Pole. Early during the mission, the OMEGA instrument (Visible and Infrared Mineralogical Mapping Spectrometer) on board Mars Express had already found previously undetected perennial deposits of water-ice. They are sitting on top of million-year old layered terrains and provide...

The amount of water trapped in frozen layers over Mars' south polar region is equivalent to a liquid layer about 11 metres deep covering the planet. This new estimate comes from mapping the thickness of the dusty ice by the Mars Express radar instrument that has made more than 300 virtual slices through layered deposits covering the pole. The radar sees through icy layers to the lower boundary, which in places is as deep as 3.7 kilometres below the surface.  "The south polar layered...

By ALICIA CHANG Associated Press Video: Possible Water Found on Mars LOS ANGELES -- New photographs from space suggest that water occasionally flows on the frigid surface of Mars, raising the tantalizing possibility that it is hospitable to life, scientists reported Wednesday. The new images, taken by NASA's Mars Global Surveyor before it lost contact with Earth, do not actually show flowing water. Rather, they show changes in craters that provide the strongest evidence yet that...

LOS ANGELES -- After decades of scouring images of Mars for signs of water, scientists believe they have found stunning evidence that water may even now be flowing through the Red Planet's frigid surface. The news excited scientists who hunt for extraterrestrial life. If the finding is confirmed, they say, all the ingredients favorable for life on Mars would be in place: liquid water and a stable heat source. "This is a squirting gun for water on Mars," said Kenneth Edgett, a scientist at San...

The new images, taken by NASA's Mars Global Surveyor before it lost contact with Earth, do not actually show flowing water. Rather, they show changes in craters that provide the strongest evidence yet that water coursed through them as recently as several...

By ALICIA CHANG LOS ANGELES - A provocative new study of photographs taken from orbit suggests that liquid water flowed on the surface of Mars as recently as several years ago, raising the possibility that the Red Planet could harbor an environment favorable to life. The crisp images taken by the Mars Global Surveyor do not directly show water. Rather, they show apparently recent changes in surface features that provide the strongest evidence yet that water even now sometimes flows on the...

The Fourth International Conference on Mars Polar Science and Exploration was recently held in Davos, Switzerland. It was an appropriate meeting place for those who study cold regions, because as Walter Ammann of the Swiss Federal Institute for Snow and Avalanche Research noted, "We like to joke that in Davos, we have 9 months of winter, and 3 months of cold." Snow had not yet accumulated on the Alps that tower over the small village, but the proximity to nearby mountains and glaciers...

This mosaic image was built from ten observations by the OMEGA Visible and Infrared Mineralogical Mapping Spectrometer on board ESA's Mars Express, when the spacecraft was flying at about 6000 kilometres altitude over the south pole during the Martian early to mid-Spring. The dark region within the bright seasonal cap below and to the right of the pole is the so-called "Ëœcryptic region' on Mars. During Southern spring, this area "Ëœmysteriously' become much darker than...

Planetary scientists have discovered the highest clouds above any planetary surface. They found them above Mars using the SPICAM instrument on board ESA's Mars Express spacecraft. The results are a new piece in the puzzle of how the Martian atmosphere works. Until now, scientists had been aware only of the clouds that hug the Martian surface and lower reaches of the atmosphere. Thanks to data from the SPICAM Ultraviolet and Infrared Atmospheric Spectrometer onboard Mars Express, a fleeting...

NASA -- If you live somewhere in the northern hemisphere between Jacksonville, Florida and Juneau, Alaska or in the southern hemisphere between Porto Alegre in Southern Brazil and Tierra del Fuego, in southern Argentina, you may have noticed that since 1965, there are less rainy and snowy days. You may have also noticed that when storms do come by they bring more rain or snow than they used to in the past. Both of those observations have been proven to be true. What you may not know, though,...
