Mars plays host to a huge number of dune fields — regions where fine wind-blown material gets deposited to form arguably some of the most beautiful dunes that can be found on any planetary body in the solar system. Using the powerful High-Resolution Imaging Science Experiment (HiRISE) camera on board NASA’s Mars Reconnaissance Orbiter, planetary scientists have an orbital view on these features that aid our understanding of aeolian (wind-formed) processes and Martian geology. Here are some of our favorite Mars dunes as seen by HiRISE.
High resolution digital terrain models, or DTMs, are topographic maps of Mars as imaged by the High-Resolution Imaging Science Experiment (HiRISE) on board NASA’s Mars Reconnaissance Orbiter (MRO). They are created by grabbing two separate images of the same region of the Martian surface during different orbits. These “stereo pairs” (with different angles of inclination) are used to precisely measure the elevation of the landscape after a complex and time consuming series of steps including calibration by mission scientists and calculations by a powerful algorithm. The result is nothing short of beautiful. So get immersed in Mars’ technicolor landscape and see the scale of some of those awesome geological formations on the Red (blue, green and yellow) Planet.

The High-Resolution Imaging Science Experiment (HiRISE) camera carried by NASA’s Mars Reconnaissance Orbiter (MRO) has spotted a strange geological feature that, for now, defies an obvious explanation. Found at the southern edge of Acidalia Planitia, small pits with raised edges appear to hug a long ridge. So far, mission scientists have ruled out impact craters and wind as formation processes, but have pegged the most likely cause to be glacial in nature.
Relatively recently, water blasted out from an underground aquifer on Mars, carving out deep flood channels in the surface that were later buried by lava flows, radar images complied from an orbiting NASA probe shows.
In a nutshell, the Mars Reconnaissance Orbiter has used radar to look inside Mars’ crust, under a layer of ancient lava, exposing a valley that was formed by a huge surge of water! If that’s not crazycool, I don’t know what is.
