Type locations for the diversity of  currently identified mineral spectral signatures have been  compiled into this library of spectra. The type spectra  assembled into the MICA library represent the results of over  seven years of measurements from CRISM of the surface of Mars and represent the compilation of many researchers' efforts.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.mro-m-crism-4-typespec-v1.0_m7wy-5eam", "issued": "2021-05-21", "keyword": ["mars", "mars-reconnaissance-orbiter"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=MRO-M-CRISM-4-TYPESPEC-V1.0", "license": "http://www.usa.gov/publicdomain/label/1.0/", "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": "MRO MARS CRISM 4 TYPE SPECTRA \n                                      LIBRARY V1.0"}
