Tucson AZ (SPX) Sep 05, 2008 - A fork-like conductivity probe has sensed humidity rising and falling beside NASA's Phoenix Mars Lander, but when stuck into the ground, its measurements so far indicate soil that is thoroughly and perplexingly dry.
Pasadena CA (JPL) Sep 05, 2008 - Spirit continues to ride out the Martian winter by doing minimal activities to conserve power. The rover completes very light science observations every three to four Martian days, known as sols, and relays data to NASA's Odyssey orbiter to be transmitted to Earth every four sols.
Pasadena CA (JPL) Sep 05, 2008 - Like a backpacker hiking up a steep grade, Opportunity has been trying to gain elevation using a switchback approach inside Victoria Crater.
Tucson AZ (SPX) Sep 03, 2008 - The single-piece primary and tertiary mirror blank cast for the LSST is perfect, say project astronomers and engineers.
Pasadena CA (JPL) Sep 03, 2008 - Opportunity faces several challenges on the way out of Victoria Crater but continues to make steady progress. The first of these is a traverse of approximately 10 meters (30 feet, a little longer than a double-decker bus) across a sandy, 17-degree slope.
Tucson, AZ (JPL) Sep 03, 2008 - Scientists have begun to analyze a sample of soil delivered to NASA's Phoenix Mars Lander's wet chemistry experiment from the deepest trench dug so far in the Martian arctic plains. Phoenix has also been observing movement of clouds overhead.
Tucson AZ (SPX) Sep 03, 2008 - NASA's Phoenix Mars Lander, having completed its 90-day primary mission, is continuing its science collection activities. Science and engineering teams are looking forward to at least another month of Martian exploration.
Moffett Field CA (SPX) Sep 02, 2008 - Hans Amundsen is a Norwegian geologist and the expedition leader of AMASE (Arctic Mars Analog Svalbard Expedition). AMASE is an international, interdisciplinary scientific research project that since 2003 has traveled to Svalbard, a group of islands in the High Arctic that provides some of the best sites on Earth for doing Mars-related field research.
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 (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.
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.
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.
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.
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.
