Mars Global Surveyor: MOLA

The Mars Orbiter Laser Altimeter (MOLA) generates altimetry profiles that are used to create global topographic maps. The MOLA instrument stopped acquiring altimetry data on June 30, 2001, and since then has operated in passive radiometry mode. MOLA data sets are produced by the MOLA Science Team and archived by the PDS Geosciences Node.

April 27, 2007 The final delivery of MOLA radiometry data is now online.

MOLA Products and IAU Coordinates

The final version (Version L) of the MOLA PEDR data set was generated using the IAU 2000 coordinate system. The final version of the MOLA topographic maps (MEGDRs) was generated from the Version L PEDRs, and therefore also uses the IAU 2000 coordinate system. Older versions of MOLA PEDRs and topographic maps were created in the IAU 1991 system. For more information, see the PEDR Data Set Information under Data Set Overview.

MOLA Data Distribution Schedule

MOLA data were delivered to the PDS every three months while the altimeter was still collecting data. Since June 30, 2001, MOLA has been used as a passive radiometer. The archive of radiometry data has passed a PDS peer review.
