MESSENGER: MASCS

March 8, 2013. MESSENGER Release 9 includes MASCS EDR and CDR data acquired through September 17, 2012, along with revisions to previously released data. See the EDR ERRATA.TXT and CDR / DDR ERRATA.TXT for details.

This is also the first release to include MASCS Derived Data Products (DDR). These products were acquired through March 25, 2012. See the CDR / DDR AAREADME.TXT and ERRATA.TXT for details.

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.
