This map shows the thickness of the north polar layered deposits on Mars
as measured by the Shallow Radar instrument on NASA's Mars Reconnaissance
Orbiter.
The Shallow Radar instrument was provided by the Italian Space Agency. Its
operations are led by the University of Rome and its data are analyzed by
a joint U.S.-Italian science team. JPL, a division of the California
Institute of Technology, Pasadena, manages the Mars Reconnaissance Orbiter
for the NASA Science Mission Directorate, Washington
