MESSENGER: MASCS

March 7, 2014. MESSENGER Release 11 includes MASCS raw and calibrated data (EDR and CDR) through September 17, 2013, and advanced products (DDR) through March 17, 2013. See the ERRATA.TXT file in each data set's top-level directory for details about this release.

A new version of the MASCS CDR and DDR Reader software is also available.

MASCS is the Mercury Atmospheric and Surface Composition Spectrometer instrument on MESSENGER. The data sets are produced by the MASCS Science Team at Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland.

MASCS has two subsystems, UVVS (Ultraviolet and Visible Spectrometer) and VIRS (Visible and Infrared Spectrograph). UVVS data are archived by the PDS Atmospheres Node, and VIRS data are archived by the PDS Geosciences Node. Both data sets are stored on the same archive volume, available from both nodes.
