If Martian life existed a few billion years ago, scientists think any plant-like microbes would have left behind a stringy fuzz of fibers. That's because here on Earth, researchers now say they have found such ancient fuzz, called cellulose, preserved in chunks of salt deposited more than 250 million years ago -- making it the oldest biological substance yet recovered. The announcement comes about a week after a team of planetary scientists announced discovering evaporated salt...

Applying techniques used to scope out caves on Earth to probe the possibility of caves on Mars is paying off. NAU researchers Glen Cushing and Jut Wynne, working at the U.S. Geological Survey, propose that photos from the Mars Odyssey mission reveal football-field size holes that could be entrances to caves. "If there is life on Mars, there is a good chance you'd find it in caves," said Wynne, an NAU graduate student in biological sciences and project leader for the USGS Earth-Mars Cave...

Every spring brings violent eruptions to the south polar ice cap of Mars, according to researchers interpreting new observations by NASA's Mars Odyssey orbiter. Jets of carbon dioxide gas erupting from the ice cap as it warms in the spring carry dark sand and dust high aloft. The dark material falls back to the surface, creating dark patches on the ice cap which have long puzzled scientists. Deducing the eruptions of carbon dioxide gas from under the warming ice cap solves the riddle of the...

JPL -- NASA has suspended use of one of the mineral-identifying tools on the Opportunity Mars rover while experts troubleshoot a problem with getting data from the instrument, the robot's miniature thermal emission spectrometer. "As always, our first priority is to protect the instrument, so we have turned it off while we plan diagnostic tests," said Jim Erickson of NASA's Jet Propulsion Laboratory, Pasadena, Calif., project manager for the Mars Exploration Rover Project. "Opportunity's other...
