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 ...

Evidence of water accelerating erosion might help with the search for life. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Now we can factor ...

Mars once had sprawling river systems that rivaled major watersheds on Earth, and scientists have now identified the biggest ...

Freelance writer Amanda C. Kooser covers gadgets and tech news with a twist for CNET. When not wallowing in weird gear and iPad apps for cats, she can be found tinkering with her 1956 DeSoto. Sand ...

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 ...

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 ...

View of a Mars polar trough, approximately 20 kilometers across and a few hundred meters deep. The image shows a mound (orange dot) and a depression (blue dot) that are concentrically layered. Some 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 ...

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 ...

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 ...
