Mars Express: MaRS

MaRS (Mars Express Radio Science) uses radio waves to study both the surface and atmosphere. It measures local variations in gravity over the surface of Mars and provides pressure and temperature profiles of the atmosphere. The MaRS Principal Investigator is Dr. Martin Pätzold, University of Cologne, Germany.

The primary source for MaRS data is the ESA Planetary Science Archive.

Through a cooperative agreement between ESA and NASA, the PDS Geosciences Node is hosting a copy of the MaRS data archive.

• Copy of MaRS Data at the PDS Geosciences Node, Washington University in St. Louis
  • Raw data, nominal Mission
  • Raw data, extended Mission
  • Reduced occultation data

More information about MaRS is on the ESA web site.

May 7, 2009. The new Reduced Occultation data set, which contains temperature and pressure profiles, has been temporarily removed while the Radio Science Team corrects some errors that were discovered in the data. The revised version of this data will be available here by approximately June 7, 2009.
