Updated the modification date in the data and browse labels in releases from 2 to 7 to correspond with their release dates. Updated the modification dates in the browse collection, data collection, document collection, release notes, and bundle to reflect the release date accondingly. 2024-05-08 7.1 Updated sim and emap labels corresponding to the observations between S_0016XX and S_0786XX . Fixed stop subspacecraft longitude location so it matches the value in the RDR label. 2024-03-01 7.0 Updated for Release 7 2023-12-01 6.0 Updated for Release 6 2023-09-01 5.0 Updated for Release 5 2023-06-01 4.0 Updated for Release 4 2023-03-01 3.0 Updated for Release 3 2022-12-01 2.0 Updated for Release 2 2022-06-01 1.0 Initial release 2006-12-06T02:08:22.929Z 2025-08-14T06:16:14.088Z Science Derived Surface Geosciences MARS RECONNAISSANCE ORBITER Mission urn:nasa:pds:context:investigation:mission.mars_reconnaissance_orbiter collection_to_investigation MARS RECONNAISSANCE ORBITER Host urn:nasa:pds:context:instrument_host:spacecraft.mro is_instrument_host SHALLOW RADAR for MRO Instrument urn:nasa:pds:context:instrument:sharad.mro is_instrument Mars Planet urn:nasa:pds:context:target:planet.mars collection_to_target Reference to the Planet - Mars target urn:nasa:pds:context:resource:resource.mro_sharad_simulations_online has_resource urn:nasa:pds:mro_sharad_simulations:document:userguide collection_to_document 10.1109/LGRS.2016.2581799 P.
