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, 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.

• MARSIS Experiment Data Record (raw data)
• MARSIS Subsurface Reduced Data
• MARSIS Active Ionospheric Sounder data

More information about MARSIS is on the MARSIS web site.

Coming soon: The Mars Orbital Data Explorer will be able to search for MARSIS data.

June 16, 2008: The first releases of MARSIS data have been added to the archive.
