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

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 ...

Scientists have mapped out ancient, large-scale river systems across the surface of Mars, providing compelling evidence of ...

For decades, we have been imaging the surface of Mars with ever-finer resolution, cataloging a huge range of features on its surface, studying their composition, and, in a few cases, dispatching ...

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 ...

In this observation, it looks like we can view a couple of erosional windows in the scalloped (ice-rich) unit. This area is a good place for imaging samples of the contact to understand the deposition ...

Mars Express has found a unique butterfly-shaped crater on Mars. This formation resulted from a space rock hitting at a low angle. The impact ejected debris in two lobes, creating wing-like structures ...

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 ...

Conditions at the surface of Mars are enigmatic and complex and have varied substantially over the course of the planet’s history. The roles of erosion, transport and chemical weathering in shaping ...
