This image montage features a two-dimensional radar cross section of Mars' north polar cap collected by SHARAD instrument on NASA's Mars Reconnaissance Orbiter spacecraft (top), and a color image mosaic of the polar cap from NASA's Viking project (bottom)
This illustration schematically shows where the Shallow Radar instrument on NASA's Mars Reconnaissance Orbiter detected flood channels that had been buried by lava flows in the Elysium Planitia region of Mars.
NASA's Mars Reconnaissance Orbiter color-codes thickness estimates in a newly found, buried deposit of frozen carbon dioxide, dry ice, near the south pole of Mars contains ~30 times more carbon dioxide than previously estimated to be frozen near the pole.
This image shows a cross-section of a portion of the north polar ice cap of Mars, derived from data acquired from NASA's Mars Reconnaissance Orbiter's Shallow Radar instrument. The data depict the region's internal ice structure.
NASA's Mars Reconnaissance Orbiter has detected widespread deposits of glacial ice in the mid-latitudes of Mars. This map of a region known as Deuteronilus Mensae, in the northern hemisphere, shows locations of the detected ice deposits in blue.
