ENHANCING THE RELAB SPECTRAL DATABASE FOR THE MODERN ERA OF PLANETARY SCIENCESTHE REFLECTANCE EXPERIMENT LABORATORY (RELAB) FACILITY HOUSED AND OPERATED AT BROWN UNIVERSITY HAS AMASSED A SIGNIFICANT LIBRARY OF VISIBLE-NEAR INFRARED-INFRARED (VIS-NIR-IR) REFLECTANCE SPECTRA OVER THE LAST ~30 YEARS. THE CURRENT RELAB SPECTRAL DATABASE CONTAINS ~24 000 SPECTRAL FILES CORRESPONDING TO ~12 000 UNIQUE SAMPLES INCLUDING A SIGNIFICANT NUMBER OF LUNAR AND METEORITE SAMPLES. THE LATTER ARE PARTICULARLY IMPORTANT GIVEN PAST RECENT AND UPCOMING MISSIONS THAT UTILIZE VIS-NIR-IR WAVELENGTHS (E.G. MARS MGS ODYSSEY MARS EXPRESS MRO CHANDRAYAAN-1 DAWN MESSENGER OSIRIS-REX HAYABUSA-2 ETC.). ALL DATA COLLECTED AT RELAB HAVE BEEN PUBLICLY AVAILABLE OVER THIS TIME PERIOD AND AVAILABLE TO THE WORLD. HOWEVER THE NEEDS OF THE SCIENTIFIC COMMUNITY TO EASILY SEARCH AND ACCESS THIS LARGE DATABASE HAVE GROWN TREMENDOUSLY DURING THE DIGITAL AGE AND IT IS NECESSARY FOR THE DATABASE TO EVOLVE IN ORDER TO MEET THOSE NEEDS. HERE WE PROPOSE SEVERAL IMPORTANT STEPS TO SIGNIFICANTLY INCREASE AND IMPROVETHE USABILITY AND SCIENTIFIC IMPACT OF THE VAST RELAB SPECTRAL LIBRARY. THE WORK PLAN CAN BE DIVIDED INTO THREE MAJOR TASKS:TASK 1: RESTRUCTURE EXISTING SPECTRAL DATABASE/CATALOG CORRECT INCONSISTENCIES AND INCORPORATE INTO A RELATIONAL DATABASE MANAGEMENT SYSTEM TO PREPARE FOR INTEGRATION WITH AN ONLINE SEARCH TOOL. WHEN POSSIBLE MISSING SAMPLE INFORMATION WILL BE ADDED TO THE DATABASE AS WELL AS AUXILIARY SAMPLE INFORMATION (CHEMISTRY MINERALOGY PHOTOS ETC.).TASK 2: FORMAT ALL EXISTING SPECTRAL FILES TO BE IN COMPLIANCE WITH PDS4 STANDARDS AND AFTER PEER REVIEW DELIVER ALL EXISTING SPECTRAL DATA TO THE PDS GEOSCIENCES NODE (AT WASHINGTON UNIV. IN ST. LOUIS) FOR FORMAL ARCHIVING THROUGH NASA. OUR GOAL IS TO ESTABLISH A SYSTEM IN WHICH ALL FUTURE SPECTRAL DATA ARE MADE PDS-COMPLIANT AS THEY ARE COLLECTED ENSURING SIMPLE AND STREAMLINED DELIVERY TO THE PDS IN FUTURE YEARS AS THE DATABASE GROWS.TASK 3: CREATE A USER-FRIENDLY ONLINE TOOL FOR SEARCHING THE RELAB DATABASE EXAMINING SPECTRAL PLOTS AND DOWNLOADING DATA AS DESIRED. AUXILIARY INFORMATION (E.G. CHEMISTRY MINERALOGY PHOTOS JOURNAL REFERENCES) WILL BE INCLUDED WHEN AVAILABLE. THE TOOL WILL ALSO INCLUDE AN ONLINE METHOD FOR SUBMITTING SAMPLE MEASUREMENT REQUESTS AND SAMPLE INFORMATION TO RELAB. THIS TOOL WITH BEMADE AVAILABLE THROUGH THE PDS GEOSCIENCES NODE AND WILL BE MIRRORED AT BROWN UNIVERSITY.THE EXPECTED RESULT OF THIS PROJECT IS A SIGNIFICANT AND NECESSARY INCREASE IN THE ACCESSIBILITY USABILITY AND VISIBILITY OF THE NASA RELAB SPECTRAL DATABASE. THIS WORK IS RELEVANT TO THE PDART CALL IN THAT IT FOCUSES ON ARCHIVING OF SPECTRAL DATA AND CREATING A TOOL FOR SEARCHING AND USING THOSE DATA. ALL EXISTING SPECTRA AND AUXILIARY DATA WILL BE ARCHIVED IN THE PDS (FOLLOWING REVIEW) AT THE END OF THE AWARD PERIOD. WE WILL ALSO DEVELOP A WEB-BASED TOOL HOSTED THROUGH THE PDS AND MIRRORED AT BROWN THAT WILL ALLOW USERS EASY SEARCH AND DOWNLOAD CAPABILITIES. THESE ACTIVITIES ARE OUTSIDE THE CURRENT SCOPE OF FUNDING FOR THE RELAB FACILITY AND THE PDSGEOSCIENCES NODE AND THERE ARE CURRENTLY NO ESTABLISHED FUNDS TO SUPPORT SUCH WORK BEYOND RESPONDING TO THIS PDART CALL.
