The SPICE data contains geometric and other ancillary information needed to recover the full value of science instrument data. In particular SPICE kernels provide spacecraft and planetary ephemerides, instrument mounting alignments, spacecraft orientation, spacecraft sequences of events, and data needed for relevant time conversions.", "identifier": "urn:nasa:pds:context_pds3:data_set:data_set.vo1-vo2-m-spice-6-v1.0_kfs8-x87r", "issued": "2018-06-26", "keyword": ["mars", "viking"], "landingPage": "https://pds.nasa.gov/ds-view/pds/viewDataset.jsp?dsid=VO1%2FVO2-M-SPICE-6-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": "VO1/VO2 MARS SPICE KERNELS V1.0"}
