The USGS Astrogeology Science Center in Flagstaff, Arizona recently released a series of geologic Martian maps that could all be impactful to future missions to the Red Planet. Does size matter? In ...

This is a geologic map of Mars. Colors show distribution of 44 map units (Robinson projection, Mars Orbiter Laser Altimeter (MOLA) shaded-relief background). For example, greens represent mainly ...

Currently, five spacecraft are investigating Mars, and a swarm of new missions to the Red Planet either have been launched or are in development. They are designed to probe the surface, subsurface, ...

PSI: A geologic mapping project using NASA spacecraft data offers new evidence that expansive lakes existed long ago on Mars. The research points to a series of sedimentary deposits consistent with ...

Billions of years ago, water flowed across Mars. Most scientists agree the red planet had rivers. But did those rivers flow into an ocean? New research from the University of Arkansas found strong ...

Using two high-resolution photographs of the same surface, geologists can produce Digital Terrain Models (DTMs). DTMs are hugely useful to researchers looking to measure and model geological processes ...
