SCIENCE GOALS: SPECTRAL MEASURES OF MATURITY IN THE VISIBLE PORTION OF THE ELECTROMAGNETIC SPECTRUM MODESTLY CORRELATE WITH MAGNETIC INDICES OF LUNAR SOIL SAMPLES ENABLING AN EVALUATION OF LUNAR SURFACE MATURATION PROCESSES. NEWLY ACQUIRED DATA OF THE LUNAR SURFACE FROM MULTISPECTRAL INSTRUMENTS (E.G. THE MOON MINERALOGY MAPPER AND THE KAGUYA MI) THE DIVINER LUNAR RADIOMETER LROC WAC AND THE MINI-RF RADAR NOW ALLOW US TO EXPLORE MATURITY RELATIONSHIPS AT A VARIETY OF WAVELENGTH REGIONS RELATIVE TO CLEMENTINE COLOR DATA. OUR PRELIMINARY INVESTIGATIONS SUGGEST THAT THE MATURITY OF FEATURES CAN BE IDENTIFIED AT A VARIETY OF WAVELENGTHS THOUGH THE FEATURES MAY MANIFEST DIFFERENTLY DEPENDING ON THE WAVELENGTH REGION EXAMINED. EXAMINATION OF THREE CRATERS OF DIFFERING AGES (CLASSIFIED AS "YOUNG" "INTERMEDIATE" AND "OLD") SUGGEST THAT AGE EFFECTS ARE SEEN IN ALL WAVELENGTHS. HOWEVER NO DETAILED STUDY INTEGRATING THESE MULTIPLE PERSPECTIVES ACROSS THE LUNAR SURFACE HAS YET BEEN PERFORMED TO BETTER UNDERSTAND THESE POTENTIAL RELATIONSHIPS. HERE WE PROPOSE AN INTEGRATED STUDY OF CRATER EJECTA BLANKETS TO PROBE MATURATION PROCESSES TO BETTER UNDERSTAND HOW CRATER EJECTA DEGRADE IN VARIOUS TERRAINS ACROSS THE LUNAR SURFACE AS SEEN IN REMOTE SENSING DATA SPANNING FROM THE UV TO MICROWAVE WAVELENGTHS. PROPOSED METHODOLOGY: WE WILL INVESTIGATE THE EJECTA BLANKETS OF YOUNG LUNAR CRATERS USING A VARIETY OF DATA SETS AT A VARIETY OF WAVELENGTHS TO BETTER UNDERSTAND THEIR EMPLACEMENT MATURITY AND DEGRADATION HISTORY. SPECIFICALLY WE WILL ANALYZE DATA FROM THE SPECTROMETER ON BOARD KAGUYA LRO'S DIVINER THE LROC WAC LRO-LAMP AND THE MINI- RF INSTRUMENT TO EXAMINE MATURITY OF LUNAR MATERIALS SPECIFICALLY EJECTA BLANKETS OF YOUNG CRATERS AND ASSIGN (RELATIVE) AGES TO THESE CRATERS BASED ON THE CALCULATED MATURITY WITH EACH DATA SET. WE WILL ALSO LEVERAGE CLEMENTINE COLOR DATA TO GENERATE OMAT MAPS TO ENABLE COMPARISONS WITH A STANDARD MATURITY INDEX. THIS WILL BE DONE IN 4 MAIN TASKS: 1) EXAMINE RADAR SCATTERING CHARACTERISTICS OF YOUNG CRATER EJECTA ACROSS THE LUNAR SURFACE 2) EXAMINE THESE SAME CRATERS IN OPTICAL THERMAL AND UV-VIS DATA SETS TO IDENTIFY ANY MATURITY EFFECTS ACROSS WAVELENGTHS 3) INTEGRATE RELATIVE AGES FROM DIFFERENT DATA SETS AND COMPARE WITH OMAT; 4) EXAMINE SPECIFIC CORRELATIONS BETWEEN INDICES IDENTIFIED IN VARIOUS DATA SETS. RELEVANCE OF THE PROPOSED WORK TO THE LUNAR DATA ANALYSIS PROGRAM (LDAP): THE LDAP CALL STATES: "AN INVESTIGATOR MAY PROPOSE A STUDY...BASED ON ANALYSIS OF LUNAR DATA COLLECTED BY SPACECRAFT AT THE MOON... INCLUDING DATA FROM THE MOON MINERALOGY MAPPER (M3) AND THE LUNAR RECONNAISSANCE ORBITER (LRO). WE PROPOSE TO USE DATA FROM BOTH LRO (UTILIZING DATA FROM THE MINI-RF DIVINER AND LROC INSTRUMENTS) AND THE M3 INSTRUMENT TO UNDERSTAND MATURATION OF CRATER EJECTA. BY UTILIZING MULTIPLE DATA SETS AT MULTIPLE WAVELENGTHS WE HOPE TO BE ABLE TO PROVIDE A MORE COMPLETE UNDERSTANDING OF THE AGE OF LUNAR MATERIALS AND HOW THE DEGRADATION AND MATURATION OF CRATER EJECTA IS SEEN IN REMOTELY SENSED DATA. THE CALL ALSO ALLOWS FOR: ...DATA ANALYSES [REQUIRING] THE USE OF OLDER MISSION DATA SETS (E.G. APOLLO CLEMENTINE) " IN THE CONTEXT OF ENHANCING THE ANALYSIS AND UNDERSTANDING OF THE DATA FROM THE MISSIONS LISTED ABOVE. THE USE OF OLDER DATA SETS AS COMPLEMENTARY/SUPPLEMENTARY DATA SETS TO THE MISSIONS LISTED ABOVE FOR THE PURPOSE OF CREATING A NEEDED DATA PRODUCT (E.G. MAPS) FOR ANALYSIS IS ALLOWABLE." WE WILL BE USING CLEMENTINE DATA TO GENERATE OMAT MAPS TO COMPARE WITH THE MORE RECENT DATA FROM LRO. REMOTE SENSING OF THE MATURITY OF IMPACT CRATER EJECTA IS A CRITICAL METHOD FOR DETERMINING THE RELATIVE AGES OF IMPACT CRATERS AND THUS THE NATURE OF THE RECENT (<1GA) BOMBARDMENT HISTORY OF THE MOON. COMPARISON OF THESE DATA SETS WILL ALLOW FOR AN IMPROVED UNDERSTANDING OF HOW EJECTA MATURITY EXPRESSES ITSELF BOTH OPTICALLY AND IN RADAR DATA.
