The MESSENGER Mercury Laser Altimeter (MLA) instrument is a solid-state pulsed laser that measures the distance between the spacecraft and the surface of Mercury to a 30-cm precision at ranges up to 1000 km.  Data from the MLA will be used to map northern hemisphere topography and the altimetry of polar craters.

ACT-REACT Qucikmap allows users to explore images and data from MESSENGER's orbital mission. Once data are publically available at the PDS, the images are also available to be explored here in QuickMap. An online tutorial for using ACT-REACT QuickMap is available at http://messenger-act.actgate.com/msgr_public_released/act_docs/qmap.pdf .
