3-D Subsurace Mars Radar Volumes

Three-dimensional subsurface radar volumes generated from thousands of 2-D radar profiles by the Shallow Radar sounder onboard the Mars Reconnaissance Orbiter are revealing new information about the polar regions of Mars.

Above, cut-away perspective view (toward 150°E) into the depth-converted Planum Boreum SHARAD 3-D volume, showing radar-return power (blue high, white low) from previously known (black) and buried (red) features within the north polar cap. The SHARAD no-data zone is due to MRO’s orbit inclination. Depth conversion assumes pure water ice (εʹ = 3.15). Scale is approximate (varies in this perspective), with vertical exaggeration of 136:1.
