Mars Global Surveyor

The Mars Global Surveyor (MGS) began its primary mission on March 9, 1999, and continued through a series of extended missions until November 2, 2006, when communication with the spacecraft was lost.

MGS carried these experiments:

  • MOLA - Mars Orbiter Laser Altimeter
  • MOC - Mars Orbiter Camera
  • TES - Thermal Emission Spectrometer
  • MAG/ER - Magnetometer/Electron Reflectometer
  • RSS - Radio Science Subsystem
  • Accelerometer

The PDS Geosciences Node archives TES, MOLA, and Radio Science data. Other data sets are archived at other PDS Nodes.


Follow the instrument links above to find MGS data products online at the Geosciences Node or other PDS nodes.

Data from the MGS Primary Mission are also available on CD-ROM or DVD-ROM free of charge to NASA-funded investigators. Others may obtain them from the National Space Science Data Center (NSSDC) for a nominal fee. For more information, contact us at

The MGS Science Sampler CD-ROM was released early in the mission to provide samples of the types of data products each instrument would generate.

Online Tools

Mars Orbital Data Explorer website Mars Orbital Data Explorer - Provides search, display, and download  tools for selected MGS data sets.


The MGS Archive Plan describes the generation, validation, and release of MGS science archives. (Feb. 11, 1999, 179 KB, PDF). The Addendum to the Archive Plan describes a revised plan for the release of mapping phase data (Sept. 30, 1999, xxx KB, PDF).

PDS Catalog information is archived along with the science data:

What's New
