MOLA topographic images of the two hemispheres of Mars. This image appeared on the cover of Science magazine in May 1999. The Mars Orbiter Laser Altimeter (MOLA) was one of five instruments on the Mars Global Surveyor (MGS) spacecraft, which operated in Mars orbit from September 1997 to November 2006. However, the MOLA instrument transmitted ...

Coloring of the base map indicates relative elevations, based on data from the Mars Orbiter Laser Altimeter on NASA's Mars Global Surveyor. Whites and browns indicate the highest elevations (+12 to +8 km); followed by pinks and reds (+8 to +3 km); yellow is 0 km; greens and blues are lower elevations (down to −8 km).
A study with the Mars Orbiter Laser Altimeter, Thermal Emission Imaging System (THEMIS) and the Mars Orbiter Camera (MOC) support the idea that Warrego Valles was formed from precipitation. [31] At first glance they resemble river valleys on Earth. But sharper images from more advanced cameras reveal that the valleys are not continuous.

The instrument "zaps" rocks on Mars's surface with a laser and collects the light created by the resulting plasma. That light is then analyzed to determine the present elements.
