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. Using techniques similar to oil
prospecting on Earth, the instrument analyzes
reflections of radio waves in the upper 2-3 km of
Martian crust to reveal the subsurface structure. It is
able to distinguish between dry, frozen and wet soil.
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 will host a copy of the MARSIS
data archive on this web site when it becomes available.
The MARSIS instrument was fully deployed on June 22,
2005, and data are expected to be released in the fall
of 2006..
More information about MARSIS is on the
MARSIS web
site.
