The European Space Agency
Mars Express: MARSIS

The MARSIS Subsurface Sounding Radar/Altimeter primary objective is to map the distribution of water and ice in the upper portions of the Martian crust. The instrument analyzes reflections of radio waves in the upper 2-3 km of Martian crust to reveal the subsurface structure. The MARSIS Principal Investigator is Prof. Giovanni Picardi, (Roberto Orosei, acting), Universita di Roma 'La Sapienza', Rome, Italy.

The primary source for MARSIS data is the ESA Planetary Science Archive.

Through a cooperative agreement between ESA and NASA, the PDS Geosciences Node is hosting a copy of the MARSIS data archive.

More information about MARSIS is on the ESA web site.
