New evidence from Martian valley networks confirms a gradual climate shift from warm and wet during the Noachian period, ...

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 ...

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

Long before Mars turned into the frozen desert you see today, water shaped its surface in dramatic ways. Rivers cut through ...

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 ...

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 ...

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 ...

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 ...
