Lunar surveyor satellite ready for launch

Moon Maps

Surprisingly, the Moon is not as accurately mapped (particularly with altimetry data) as Mars.

LRO instrumentation is not related to Mars Express. MEX was actually loaded with left-over European-built instruments from the failed Soviet Mars-96 mission. Most of the high quality Mars mapping data is from the Mars Global Surveyer, which orbited for ten years and had a laser altimeter. LRO is closely related to the Mars Recon. Orbiter that is currently circling that planet.
