NASA's Curiosity Mars rover is continuing science observations while on the move this month.
Researchers have long known that there is water in the form of ice on Mars. Now, new research from NASA's Mars rover Curiosity shows that it is possible that there is liquid water close to the surface of Mars.
Opportunity is on the west rim of Endeavour Crater near the entrance of "Marathon Valley," a putative location for abundant clay minerals.
Research from NASA's Mars rover Curiosity has strengthened hopes that liquid water may exist near the surface of Mars, astrophysicists said on Monday.
Mars has distinct polar ice caps, but Mars also has belts of glaciers at its central latitudes in both the southern and northern hemispheres.
NASA's Mars Reconnaissance Orbiter, at Mars since 2006, made an unplanned switch on Wednesday from one main computer to a redundant one onboard, triggering a hiatus in planned activities.
New research shows Mars' buried glaciers contain enough ice to cover the entire planet with a coat three feet thick.
Monica Pondrelli and colleagues investigated the Equatorial Layered Deposits (ELDs) of Arabia Terra in Firsoff crater area, Mars, to understand their formation and potential habitability.

NASA's Low-Density Supersonic Decelerator (LDSD) project will be flying a rocket-powered, saucer-shaped test vehicle into near-space from the Navy's Pacific Missile Range Facility on Kauai, Hawaii, in June.
A new, six-year analysis of water on Mars suggests that the Red Planet has lost the equivalent of an ocean's worth of water over the past four billion years.
The Opportunity mission is now the first human enterprise to exceed marathon distance of travel on another world.
The team operating NASA's Mars Exploration Rover Opportunity learned Thursday that the long-lived rover experienced a brief amnesia event related to its flash memory, the first since a reformatting of that nonvolatile type of memory a week earlier.
