The 17th LROC Planetary Data System release includes images acquired between 2013-09-16 to 2013-12-15. This release contains 65,014 EDR images - totaling 9 TB, and 63,709 CDR images - totaling 19 TB. The difference of 1305 products between EDR and CDR volumes are a result of an LRO Sun safe event on 2013-331. An additional 18 NAC Digital Terrain Models (DTM) were also released, making a total of 189 NAC DTMs released to date.
The 16th LROC Planetary Data System release includes images acquired between 2013-06-16 to 2013-09-15. This release contains 69,168 EDR images - totaling 7.9 TB, and 69,168 CDR images - totaling 16 TB. An additional 48 NAC Digital Terrain Models (DTM) and 7 NAC Region Of Interest (ROI) mosaics were also released as part our this LROC RDR volume, making a total of 171 NAC DTMs and 100 NAC ROI mosaics released to date.
The 15th LROC Planetary Data System release includes images acquired between 2013-03-16 to 2013-06-15. This release contains 69,789 EDR images - totaling 9.8 TB, and 69,789 CDR images - totaling 20 TB. An additional 31 NAC DTM and NAC ROI mosaics were also released as part of the RDR volume. The LROC Team has updated the RDR interface to allow users to search for RDR products based on product type, location, and other field.
Important change to the LROC PDS archive -- effective immediately. New regulations from the Consolidation and Further Continuing Appropriations Act of 2013 (Public Law 113-6, Section 516) regarding Information Technology result in new lengthy purchase reviews for all NASA IT acquisitions. Due to these new reviews the LROC team has not yet been able to acquire the annual increase in disk storage required to sustain LROC operations and the full LROC PDS archive. To insure continued operations and data processing of EDR (raw image data) and RDR (maps and topography) products, the LROC Team will be deleting existing CDRs (Calibrated Data Record) products from the PDS repository.
