Curiosity has been exploring the surface of Mars since 2011, but what it found inside a rock last year has changed our ...

NASA has lost contact with one its three spacecraft orbiting Mars, the agency announced Tuesday. Meanwhile, a second Mars ...

Mars has a new showpiece for planetary scientists, and it looks uncannily like a butterfly frozen mid-flight. A fresh set of ...

Mars Express has uncovered geological evidence suggesting that some depositional process, revealed by erosion, has been at work on large scales in the equatorial regions of the planet. If so, this ...

CINCINNATI (WKRC) - New research has led scientists to believe that Mars was very likely a "planet of rivers" and once able to host life. This comes from Benjamin Cardenas of Penn State University who ...

Very interesting article and paper. Plateau retreat, deposition, and and shorelines tend toward a large body of water as an explanation except that rock layers and shorelines also say "no" to that as ...

Spiral troughs found on the surface of Mars are in situ ice-excavated canyons with a total volume 10 times that of the Grand Canyon, making them one of the largest and youngest geologic ...

Thanks to erosion wearing away surface rock on Mars, scientists using NASA’s Mars Reconnaissance Orbiter have spotted thick deposits of ice in the planet’s mid-latitudes that extend hundreds of feet ...

Most of Mars’ ancient sedimentary rocks by volume are in wind-eroded sedimentary mounds, but the connections between mound form and wind erosion are unclear. We perform mesoscale simulations of ...

This Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) image shows the results of erosion acting upon a layer of material in the south polar region of Mars. The elliptical pit in the lower left ...

NASA's Curiosity Mars Rover has spotted strange rock formations on the red planet that appear to have formed into small, twisted towers. A photo of the rock formations was shared on Twitter last month ...
