The NS experiment is a neutron spectrometer designed to observe spectra of neutrons emitted from Mercury's surface in the energy range from 0.01 eV to 7 MeV. There are five NS CDR data products: raw neutron spectra, NS counter data, galactic cosmic ray (GCR) spectra, engineering data, and gamma-ray burst data.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.mess-e-v-h-grns-3-ns-cdr-v1.0_vcdu-isw3", "issued": "2018-06-26", "keyword": ["calibration", "earth", "mercury", "messenger", "venus"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=MESS-E%2FV%2FH-GRNS-3-NS-CDR-V1.0", "modified": "2025-07-17", "programCode": ["026:005"], "publisher": {"@type": "org:Organization", "name": "National Aeronautics and Space Administration"}, "references": ["https://pds.nasa.gov"], "theme": ["Earth Science"], "title": "MESSENGER E/V/H GRNS 3 NEUTRON SPECTROMETER CDR V1.0"}
