Surface features The dark markings cover about one-third of the Martian surface, mostly in a band around theplanetbetween latitudes 10° and 40° S. Their distribution is irregular, and their gross pattern has been observed to change over timescales of tens to hundreds of years. The northern ...

as well as that of its two moons, is pitted with impact craters formed by meteoroids falling in from space. As on our Moon, the smaller craters are often filled with surface matter-mostly dust-confirming that Mars is a dry desert world. However, Martian ...
Current pixel-based methods of image analysis are too computationally expensive to feasibly discover meaningful changes in Mars surface features in NASA's large, continuously expanding database of satellite imagery. We worked on the beginning stages of a more efficient method of change detection that ...
Canals of Mars, apparent systems of long, straight linear markings on the surface of Mars that are now known to be illusions caused by the chance alignment of craters and other natural surface features seen in telescopes near the limit of resolution. The
In practice, the ice table, being closest to the surface, reaches the warmest summer temperatures and the highest water activity of any depth. Therefore, our results place some focus on the habitability conditions at the ice table at given location and epoch, though conditions within the ice ...
The modern Martian surface is unlikely to be habitable due to its extreme aridity among other environmental factors. This is the reason why the hyperarid core of the Atacama Desert has been studied as an analog for the habitability of Mars for more than 50 years. Here we report a layer en...
They are characterized as being near-surface, and their locations are near the InSight lander. Given the similarity with the low-frequency parent marsquakes (S0173a and S0235b) and the time of their occurrence, the newly detected marsquakes cannot be temperature-induced. Most likely, all ...
In spite, however, of the antique features not far from the surface, it is difficult to reconstruct the history and evolution of Roman religion. The principal literary sources, antiquarians such as the 1st-century-bceRoman scholarsVarroandVerrius Flaccus, and the poets who were their contemporar...
It's still not clear how all these features formed; polygonal forms have often been linked to sub-surface ice or permafrost typically found at higher latitudes, for example, but the presence of ice below the surface of Oxia Planum, which is at the low latitude of 18 degrees north of Mars...
