MARSIS MARSIS MARSIS (Mars Advanced Radar for Subsurface and Ionosphere Sounding) is a low frequency, pulse-limited radar sounder and altimeter developed by the University of Rome La Sapienza and Alenia Spazio (today Thales Alenia Space Italy). The Italian MARSIS instrument is operational on the European Space Agency, "Mars Express" orbiter mission. The MARSIS Principal Investigator is Giovanni Picardi from the University of Rome "La Sapienza", Italy.

MARSIS identified buried basins on Mars. MARSIS was funded by ASI (Italy) and NASA (USA). On
