THE METEOROID ENVIRONMENT NEAR THE EARTH-MOON SYSTEM IS AN ACTIVE AREA OF RESEARCH WITH APPLICATIONS ACROSS MANY PLANETARY DISCIPLINES. UNDERSTANDING THE TOTAL FLUX AND PROPERTIES OF THESE METEOROIDS IS CRITICAL TO THE SUCCESS OF FUTURE MISSIONS TO NEAR EARTH OBJECTS AS WELL AS TO THE ANALYSIS OF EXISTING OBSERVATIONS. WHILE A WIDE RANGE OF TECHNIQUES HAVE BEEN IMPLEMENTED TO ESTIMATE THE TOTAL METEOROID FLUX AND SIZE DISTRIBUTION LARGE UNCERTAINTIES STILL EXIST AS THESE ESTIMATES DIFFER BY UP TO TWO ORDERS OF MAGNITUDE. THE DYNAMICS OF IMPACT EJECTA PRODUCTION ON AIRLESS BODIES IS ANOTHER ONGOING AREA OF RESEARCH OF KEY INTEREST. INFORMATION ON THE DYNAMICS OF THESE DUST CLOUDS IS NECESSARY BOTH FOR IDENTIFYING HAZARDS FOR FUTURE MISSIONS TO SUCH BODIES AS WELL AS ANALYZING EXISTING OBSERVATIONS. THE LUNAR DUST EXPERIMENT (LDEX) ON-BOARD THE LUNAR ATMOSPHERE AND DUST ENVIRONMENT EXPLORER (LADEE) MISSION OBSERVED FROM 9/2014 TO 4/2015 A DYNAMIC AND PERMANENTLY PRESENT DUST CLOUD AROUND THE MOON PRODUCED BY CONTINUAL METEOROID BOMBARDMENT. THROUGH THE IMPLEMENTATION OF A FORWARD MODELING APPROACH USING A TWO-DIMENSIONAL SINGLE PLUME EJECTA MODEL IT WAS REVEALED THAT THIS DUST ENVIRONMENT IS SENSITIVE TO METEOROID SHOWERS. THE SPORADIC BACKGROUND CONTRIBUTION TO THE IMPACTING DUST FLUX IS DOMINATED BY HELION APEX AND ANTIHELION SOURCES OSCILLATING WITH LUNAR PHASE. AN ESTIMATE FOR THE FLUX RATIO OF HELION TO ANTIHELION SOURCES WAS DERIVED AS WELL AS THE INITIAL MASS SPEED AND ANGLE FROM SURFACE NORMAL DISTRIBUTIONS OF THE EJECTA. THE PARAMETERS OF THIS PLUME MODEL (SPEED ANGULAR AND MASS DISTRIBUTION OF THE EJECTED PLUME PARTICLES COMPRISING A PLUME) HOWEVER ARE STILL UNDETERMINED AS THE SPEED DISTRIBUTION WAS JUST RECENTLY IMPROVED TO ACCOUNT FOR THE CORRELATION BETWEEN LOCAL TIME AND ALTITUDE OF THE SAMPLING. BY IMPLEMENTING THESE DISTRIBUTIONS INTO A THREE-DIMENSIONAL SELF-CONSISTENT MULTIPLE EJECTA PLUME MODEL FITTED TO LDEX DATA WE WILL ESTIMATE THE AVERAGE TOTAL METEOROID FLUX AT 1 AU AS WELL AS THE INNER AND OUTER ANGLES THAT DEFINE LUNAR IMPACT EJECTA PLUMES. BY COMPARING OUR ESTIMATED FLUX TO EXISTING MODELS WE WILL ALSO DERIVE PROPERTIES SUCH AS THE SIZE OF THE IMPACTORS. THE OVERALL GOAL OF THIS PROPOSAL IS TO USE A FORWARD MODELING APPROACH FITTED TO THE OBSERVED DUST DISTRIBUTION ON THE MOON TO ESTIMATE THE METEOROID ENVIRONMENT AT 1 AU AND TO ADVANCE THE UNDERSTANDING OF THE FUNDAMENTAL PHYSICS BEHIND THE DYNAMICS OF IMPACT EJECTA PRODUCTION ON ALL AIRLESS BODIES. THIS APPROACH DIRECTLY ADDRESSES ONE OF NASA S PLANETARY SCIENCE GOALS AS OUTLINED IN THE SMD 2014 SCIENCE PLAN: ADVANCE THE UNDERSTANDING OF HOW CHEMICAL AND PHYSICAL PROCESSES IN THE SOLAR SYSTEM OPERATE INTERACT AND EVOLVE. THESE ADVANCES USING LDEX DATA WOULD ALSO ENHANCE THE SCIENTIFIC RETURN OF MISSIONS THROUGH THE ANALYSIS OF DATA COLLECTED BY THOSE MISSIONS WHICH THE PLANETARY SCIENCE RESEARCH PROGRAM LISTS IN THE NESSF 2017 SOLICITATION AS A TOPIC OF DESIRED RESEARCH.
