(Phys.org) —NASA research indicates hunks of frozen carbon dioxide—dry ice—may glide down some Martian sand dunes on cushions of gas similar to miniature hovercraft, plowing furrows as they go.
(Phys.org) —NASA's senior Mars rover, Opportunity, is driving to a new study area after a dramatic finish to 20 months on "Cape York" with examination of a rock intensely altered by water.
NASA's senior Mars rover, Opportunity, has just passed the shortest-daylight weeks of the long Martian year with its solar panels in encouragingly clean condition for entering a potential dust-storm season in 2018.
NASA's Opportunity Mars rover will drive down a gully carved long ago by a fluid that might have been water, according to the latest plans for the 12-year-old mission. No Mars rover has done that before.
NASA's senior Mars rover, Opportunity, worked through the lowest-solar-energy days of the mission's seventh Martian winter, while using a diamond-toothed rock grinder and other tools in recent weeks to investigate clues about ...
(Phys.org) —NASA's Mars Exploration Rover has begun climbing "Solander Point," the northern tip of the tallest hill it has encountered in the mission's nearly 10 Earth years on Mars.
(Phys.org) —NASA's Mars Exploration Rover Opportunity has driven more than half of the distance needed to get from a site where it spent 22 months to its next destination.
(Phys.org) —Approaching its 10th anniversary of leaving Earth, NASA's Mars Exploration Rover Opportunity is on the move again, trekking to a new study area still many weeks away.
(Phys.org) -- From fresh rover tracks to an impact crater blasted billions of years ago, a newly completed view from the panoramic camera (Pancam) on NASA's Mars Exploration Rover Opportunity shows the ruddy terrain around ...
In the dead of a Martian winter, clouds of snow blanket the Red Planets poles but unlike our water-based snow, the particles on Mars are frozen crystals of carbon dioxide. Most of the Martian atmosphere ...
