ESA Mars
The upper image of this composite is a –radargram´ from the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) on board ESA´ Mars Express. It shows data from the subsurface of Mars in the water-ice-rich layered deposits that surround the south pole of the planet.
The lower image shows the position of the ground track of the spacecraft (indicated by a white line) on a topographic map of the area based on data from the MOLA laser altimeter on board NASA's Mars Global Surveyor. The images are 1250 kilometers wide. Credits: NASA/JPL/ASI/ESA/Univ. of Rome/MOLA Science Team
