OBJECTIVES: WE PROPOSE TO USE ESTABLISHED GEOLOGIC MAPPING TECHNIQUES SET BY THE UNITED STATES GEOLOGICAL SURVEY (USGS) TO PRODUCE A GLOBAL GEOLOGICAL MAP OF PLUTO AT THE 1:7M SCALE. FOLLOWING ITS PLUTO FLYBY IN 2015 NASA S NEW HORIZONS SPACECRAFT HAS RETURNED HIGH QUALITY IMAGES THAT REVEAL AN UNEXPECTEDLY DIVERSE RANGE OF TERRAINS IMPLYING A COMPLEX GEOLOGICAL HISTORY. SURFACE RENEWAL IS ONGOING AS DEMONSTRATED MOST COMPELLINGLY BY THE NITROGEN ICE PLAINS OF SPUTNIK PLANITIA. PLUTO S GEOLOGICAL PROVINCES ARE OFTEN HIGHLY DISTINCT AND CAN EXHIBIT DISPARATE CRATER SPATIAL DENSITIES. THE GEOLOGY DISPLAYS EVIDENCE FOR HAVING BEEN AFFECTED BY BOTH ENDOGENIC AND EXOGENIC ENERGY SOURCES (INCLUDING INTERNAL HEATING AND INSOLATION/CLIMATIC EFFECTS) AND ITS COMPLEX NATURE IS LIKELY A CONSEQUENCE OF COMBINATIONS OF THESE INFLUENCES AFFECTING THE SURFACE TO VARYING DEGREES ON LOCALIZED SCALES. THE GLOBAL GEOLOGICAL MAP OF PLUTO THAT WE PROPOSE TO MAKE IS THE OBVIOUS AND HIGHLY NECESSARY TOOL THAT IS REQUIRED FOR FUTURE PLANETARY SCIENCE RESEARCHERS TO RESOLVE AND RATIONALIZE THE BEWILDERING COMPLEXITY OF PLUTO S SURFACE AND TO ADDRESS THE FUNDAMENTAL ISSUES OF EXACTLY WHICH PROCESSES HAVE BEEN INFLUENTIAL IN SHAPING IT AND WHEN AND WHERE THEY HAVE BEEN ACTIVE. THE PRIMARY DELIVERABLE OF THIS EFFORT WILL BE A SCIENTIFIC INVESTIGATIONS MAP (SIM) PUBLISHED THROUGH THE USGS ENABLING DISSEMINATION THROUGHOUT THE SCIENTIFIC COMMUNITY AND USE IN FUTURE SCIENTIFIC ANALYSIS. METHODS: GEOLOGIC MAPPING IS A POWERFUL ANALYTICAL TOOL THAT PLACES OBSERVATIONS OF SURFACE FEATURES INTO THEIR STRATIGRAPHIC CONTEXT IN ORDER TO DEVELOP GENERALIZED GEOLOGIC TIMESCALES THAT PROVIDE A SEQUENCE OF EVENTS AND RESPONSIBLE PROCESSES SHAPING THE EVOLUTION OF PLANETARY SURFACES. OUR 1:7M SCALE GLOBAL GEOLOGIC MAP WILL COVER MORE THAN 75% OF PLUTO S SURFACE AREA. THIS MAPPING SCALE WILL ALLOW CHARACTERIZATION OF SMALL FEATURES OF INTEREST ON THE WELL RESOLVED ENCOUNTER HEMISPHERE (COVERING ~50% OF PLUTO S SURFACE AREA AND IMAGED AT 890 M/PIXEL OR BETTER) WHILE ONLY A HANDFUL OF UNDIVIDED UNITS WILL BE DEFINED FOR THE POORLY RESOLVED ANTIENCOUNTER HEMISPHERE. EXISTING MAPPING OF SPUTNIK PLANITIA AND WRIGHT MONS BY PI WHITE AND CO-I SINGER WILL BE REVIEWED AND UPDATED ONTO THE LATEST BASE MAP. ALL OF THE NEW HORIZONS IMAGES REQUIRED TO CONSTRUCT THE BASE MAP ARE CURRENTLY AVAILABLE ON THE SMALL BODIES NODE OF THE PDS. MAPPING WILL BE PERFORMED IN ARCGIS AND WILL FOLLOW THE STANDARD PRINCIPLES OF THE MAPPING OF EXTRATERRESTRIAL BODIES AS OUTLINED IN THE 2018 PLANETARY GEOLOGIC MAPPING PROTOCOL AND REFERENCES THEREIN. TO AID IN OUR DEFINITION AND INTERPRETATION OF MAPPED UNITS WE WILL CONSTRUCT 3D STEREO ANAGLYPHS TO VISUALIZE SURFACE TOPOGRAPHY AND WILL MAKE USE OF PUBLISHED SURFACE COMPOSITION MAPS. ONCE GEOLOGIC UNITS ARE MAPPED THEIR RELATIVE AGES WILL BE DETERMINED FROM MEASURED CRATER DENSITIES AND OBSERVED STRATIGRAPHIC RELATIONSHIPS. GIS AND PDF VERSIONS OF THE COMPLETED SIM WILL BE MADE FREELY AVAILABLE FOR DOWNLOAD AT THE USGS PUBLICATIONS WAREHOUSE. RELEVANCE: ACCORDING TO ROSES APPENDIX C.7 THE PDART PROGRAM SOLICITS PROPOSALS TO GENERATE HIGHER-ORDER DATA PRODUCTS AND AIMS TO INCREASE THE AMOUNT AND QUALITY OF DIGITAL INFORMATION AND DATA PRODUCTS AVAILABLE FOR PLANETARY SCIENCE RESEARCH AND EXPLORATION . THE CREATION OF A GLOBAL GEOLOGIC MAP OF PLUTO WILL PROVIDE AN INVALUABLE RESOURCE FOR A WIDE ARRAY OF FUTURE SCIENTIFIC INVESTIGATIONS OF THE DWARF PLANET. THE CREATION OF THIS GEOLOGIC MAP IS NOT PART OF A HYPOTHESIS-BASED INVESTIGATION ALTHOUGH A SMALL AMOUNT OF DATA ANALYSIS AND INTERPRETATION WILL BE REQUIRED AS PART OF THE MAPPING PROCESS AND DEFINITION OF THE GEOLOGIC HISTORY (E.G. CRATER MEASUREMENTS AND AGE DETERMINATION ASSESSING RELATIVE AGES OF MATERIALS ETC.). THEREFORE THE PROPOSED WORK IS MORE APPROPRIATE FOR PDART THAN NFDAP.
