Catalog: HiRISE
The main HiRISE catalog contains all the information used in operating the HiRISE camera after it is attached to the MRO spacecraft. The information is divided into those related to suggesting, planning, commanding, retrieving, processing, validating, and distributing the observations. The tag that follows an observation through all these catalogs (and from Earth to Mars and back) is the unique Observation_ID. This text representation also forms the core of the product names. The HiRISE catalog also contains ancillary information needed in various uplink and downlink activities, such as the people making image suggestions, MRO project uplink files, SPICE and engineering data, and public image releases.
