Boston MA (SPX) Sep 01, 2008 - Researchers examining images of gullies on the flanks of craters on Mars say they formed as recently as a few hundred thousand years ago and in sites once occupied by glaciers. The features are eerily reminiscent of gullies formed in Antarctica's mars-like McMurdo Dry Valleys.
Pasadena CA (JPL) Sep 01, 2008 - NASA's Mars Exploration rover Opportunity is heading back out to the Red Planet's surrounding plains nearly a year after descending into a large martian crater to examine exposed ancient rock layers. Opportunity will continue its mission to characterize the environment of Mars and help scientists determine if the planet could have been a habitat for past life in our solar system.
Pasadena CA (SPX) Sep 01, 2008 - NASA's Mars Exploration Rover Opportunity has climbed out of the large crater that it had been examining from the inside since last September.
Tempe AZ (SPX) Aug 29, 2008 - New pictures from NASA's Phoenix Lander show just what a busy summer the spacecraft on Mars - and its science team at The University of Arizona in Tucson - has been having.
Dallas TX (SPX) Aug 28, 2008 - Water on Mars? Scientists suspected the presence of H2O on the surface of our planetary next-door neighbor, but it took a series of tests and University of Texas at Dallas Professor John Hoffman's instrument aboard NASA's Phoenix Mars Lander to prove it.
Tempe AZ (SPX) Aug 27, 2008 - From the location of NASA's Phoenix Mars Lander, above the Martian arctic circle, the sun does not set during the peak of the Martian summer.
Moffett Field CA (SPX) Aug 27, 2008 - NASA's Phoenix Mars Lander has taken the first-ever image of a single particle of Mars' ubiquitous dust, using its atomic force microscope.
Pasadena CA (SPX) Aug 27, 2008 - NASA's Mars Exploration rover Opportunity is heading back out to the Red Planet's surrounding plains nearly a year after descending into a large Martian crater to examine exposed ancient rock layers.
Tucson AZ (SPX) Aug 26, 2008 - The next sample of Martian soil being grabbed for analysis is coming from a trench about three times deeper than any other trench NASA's Phoenix Mars Lander has dug.
Moffett Field CA (SPX) Aug 25, 2008 - Perchlorate. Never heard of it? Join the club. But NASA's Phoenix spacecraft has found it in the soil in the icy northern plains of Mars. And now that it's been found, scientists are scrambling to explain how it got there, and what, if anything, its presence means about the habitability of the martian north.
Tucson AZ (SPX) Aug 25, 2008 - NASA's Phoenix Mars Lander has scooped up a soil sample from an intermediate depth between the ground surface and a subsurface icy layer. The sample was delivered to a laboratory oven on the spacecraft.
Moffett Field CA (SPX) Aug 22, 2008 - Before testing for life on other planets, it's useful to practice on barren areas of the Earth. One such place is Rio Tinto in Spain, where conditions are analogous to Mars. The water of that Spanish river is very acidic, similar to water scientists think may have once flowed on the martian surface.
Tucson AZ (SPX) Aug 22, 2008 - NASA's Phoenix Mars Lander scientists and engineers are continuing to dig into the area around the lander with the spacecraft's robotic arm, looking for new materials to analyze and examining the soil and ice subsurface structure.
Mountain View CA (SPX) Aug 18, 2008 - Layers of clay-rich rock have been found in Mars' Mawrth Vallis, a potential landing site for future rovers. This work, published in the August 8 issue of Science, suggests that abundant water was once present on Mars and that hydrothermal activity may have occurred.
Pasadena CA (SPX) Aug 18, 2008 - Spirit's battery levels are slowly edging upward, thanks to a slight decrease in atmospheric dust (Tau) and a gradual increase in sunlight as winter gives way to spring.
Temps AZ (SPX) Aug 18, 2008 - The Surface Stereo Imager, or SSI, on NASA's Phoenix Mars Lander has seen water frost on the ground around the spacecraft's landing site. Water frost appears in an image the SSI took on Aug. 14, 2008, at 6 a.m. local Mars time on Sol 79, the 79th Martian day after landing.
