MESSENGER: GRS and NS

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

GRS and NS are the Gamma Ray Spectrometer and Neutron Spectrometer instruments on MESSENGER. The data sets are produced by the GRS/NS Science Team at Johns Hopkins University Applied Physics Laboratory, Laurel, Maryland.
