"We knew there was ice below the surface at high latitudes of Mars, but we find that it extends far closer to the equator than you would think, based on Mars' climate today," said Shane...
Earth Sciences |"I'm incredibly excited about this," said Dyar, who will share a portion of the grant with the Los Alamos National Laboratory. "Laser-induced breakdown spectroscopy (LIBS) is a gre...
Physics and Astronomy |The methane mystery started soon after December 2003, when ESA’s Mars Express arrived in orbit around the red planet. As the Planetary Fourier Spectrometer (PFS) began taking data, Vittorio Formisano,...
Physics and Astronomy |The study is published this week in the Journal of Environmental Monitoring and will be used to interpret the data from the soil temperature sensor of NASA's Mars Science Laboratory (MSL) vehicle...
Studies and Analyses |The maneuver to change Odyssey's orbit began Sept. 30, 2008, and ended June 9, 2009, with a five-and-a-half-minute thruster firing. The rocket burn fixed the spacecraft's track so that THEMI...
Physics and Astronomy |Arizona State University researchers and scientists have created two new features for Google Earth 5.0, the popular online application that lets users tour Earth, the starry sky, and the Red Planet M...
Physics and Astronomy |Opportunity’s two-year exploration of Victoria Crater – a half-mile wide and 250 feet deep – yielded a treasury of information about the planet’s geologic history and supported previous findings indic...
Physics and Astronomy |Research professor Vincent F. Chevrier and graduate students Jennifer Hanley and Travis S. Altheide report their findings in the current issue of Geophysical Research Letters. Their work provides the ...
Earth Sciences |The McMurdo Dry Valleys of Antarctica are devoid of animals and complex plants and scientists consider them to be one of the Earth's most extreme deserts. The Valleys receive, on average, only 10...
Earth Sciences |Compiled by Helmut Lammer, PhD, Senior Editor of Astrobiology, from the Austrian Academy of Sciences, this special paper collection features a report by Pham et al. that presents a semi-analytical mod...
Physics and Astronomy |An unmapped reservoir of briny liquid chemically similar to sea water, but buried under an inland Antarctic glacier, appears to support unusual microbial life in a place where cold, darkness and lack ...
Ecology, The Environment and Conservation |The Martian volcano Olympus Mons is about three times the height of Mount Everest, but it's the small details that Rice University professors Patrick McGovern and Julia Morgan are looking at in t...
Earth Sciences |Gullies are known to be young surface features on Mars. But scientists studying the planet have struggled with locating gullies they can conclusively date. In a paper that appears on the cover of the ...
Earth Sciences |The new finding counters the previous explanation of the evenly spaced arrangement of small rocks on Mars. That explanation suggested the rocks were picked up and carried downwind by extreme high-spee...
Physics and Astronomy |And even more surprising, was that his findings revealed answers to NASA’s questions about sediment transport and surface processes on Mars. Those results are published in this month’s edition of Geol...
