The north polar layered deposits, and the bright ice cap that covers them, are very young (by geologic standards) features. To try and figure out the age of an area, or how quickly it’s being resurfaced, planetary scientists count up the number of craters at different sizes. An older surface has more [...]

Quote from Universe Today
Reconnaissance Orbiter has been circling Mars for over two years now, and has provided unprecedented views of the Red Planet with its HiRISE Camera. But did you also know that MRO is a weather-monitoring satellite, too? The Mars Climate Sounder instrument is examining the Martian atmosphere and has issued its first Mars [...]

Images of layered sedimentary deposits and deltas on Mars have provided evidence for lakes and flowing rivers that carried eroded material downstream. A team of researchers also believes there is evidence for precipitation in the Red Planet’s past. “For years scientists have been suspecting that the current appearance of the landscape has, in part, been [...]

I just saw this on the Mars Phoenix Lander’s Twitter page:
Are you ready to celebrate? Well, get ready: We have ICE!!!!! Yes, ICE, *WATER ICE* on Mars! w00t!!! Best day ever!!
Followed by:
Whoohoo! Was keeping my eye on some chunks of bright stuff & they disappeared! Sublimated! So it can’t be salt, [...]

There seems to be a never-ending flow of stunning images coming from the High Resolution Imaging Science Experiment (HiRISE) on board NASA’s Mars Reconnaissance Orbiter (MRO). In today’s high-resolution look at the Martian surface, large flat-topped hills (a.k.a. mesas) can be seen to be eroded by the Mars winds, stripping them of their material, creating [...]

This is an absolutely fantastic photo, the earth and moon are being viewed from Mars at an angle 90 degrees to the earth from the Sun. You can quite clearly see the Pacific coast of South America and the bulk of North America above it. The detail in the clouds is [...]

The image to the left shows the context of where these avalanches occurred, with white boxes indicating the locations of the more detailed image portions shown to the right (all images are false color). Material, likely including fine-grained ice and dust and possibly including large blocks, has detached from a towering cliff [...]
