WE PROPOSE TO STUDY THE INFLUENCE OF KINETIC EFFECTS FROM ENERGETIC PARTICLES UPON SATURN'S MAGNETOSPHERE THROUGH THE COUPLING OF PREVIOUSLY DEVELOPED UNIVERSITY OF MICHIGAN SPACE WEATHER MODELING FRAMEWORK (SWMF) COMPONENTS AND A GLOBAL MAGNETOHYDRODYNAMIC (MHD) MODEL. WE WILL VALIDATE OUR MODEL USING CASSINI DATA TO AUGMENT EXISTING KNOWLEDGE OF FAST ROTATING MAGNETOSPHERES. SATURN'S MAGNETOSPHERIC DYNAMICS ARE DRIVEN BY MULTIPLE INTERNAL SOURCES SUCH AS MASS LOADING FROM ENCELADUS AND CO-ROTATION (WHERE PLASMA ROTATES AT A SIMILAR RATE AS THAT OF THE PLANET) IN ADDITION TO SOLAR WIND. THESE PROPERTIES AND THE PHYSICS OFTHE INNER AND OUTER MAGNETOSPHERE PLAY A CRUCIAL ROLE IN OVERALL PLASMA DYNAMICS. HOWEVER UP UNTIL NOW THE PRIMARY KINETIC-DRIFT PHYSICS REQUIRED TO UNDERSTAND THE INNER MAGNETOSPHERE HAS NOT BEEN ACCOUNTED FOR IN GLOBAL MODELS. COUPLING THE INNER AND OUTER MAGNETOSPHERES IS CRITICAL TO UNDERSTANDING OVERALL PLASMA DYNAMICS IN SATURN'S MAGNETOSPHERE.THE OVERARCHING OBJECTIVE OF OUR PROPOSAL IS TO INVESTIGATE THE EFFECTS OF KINETIC PROCESSES OF THE INNER MAGNETOSPHERE UPON THE SYSTEM AS A WHOLE SPECIFICALLY TO INVESTIGATE THREE SCIENTIFIC OBJECTIVES: (1) HOW ARE OBSERVED PERIODICITIES IN SATURN'S RAPIDLY ROTATING MAGNETOSPHERE INFLUENCED BY ENERGY DEPENDENT DRIFTS; (2) HOW IS THE PARTICLE DISTRIBUTION AND POPULATION AFFECTED BYMECHANISMS DRIVEN THROUGH KINETIC PHYSICS AND WHAT ARE THE PROCESSES BEHIND ENERGIZATION OF THESE PARTICLES; AND (3) SATURN'S MAGNETOSPHERE EXHIBITS INTERESTING LOSS PROCESSES SUCH AS THE CREATION OF PLASMOIDS - MAGNETIC LOOPS WITH HIGH PLASMA CONTENT. WHAT IS THE RELATIONSHIP BETWEEN PLASMOIDS AND INJECTIONS OF DIFFERENT ENERGY REGIMES AND WHAT IS THE ORIGINATOR FOR THESE EVENTS?THE GRADUATE STUDENT WILL WORK WITH FACULTY MEMBERS TO ADJUST A KINETIC-DRIFT MODEL FOR SATURN'S PARAMETERS AND COUPLE THIS WITH AN EXISTING MHD GLOBAL CODE TO CREATE A NEW GLOBAL MODEL. OVER THE COURSE OF THE PROPOSED TIMELINE THERE WILL BE THREE DISTINCT PHASES. IN THE FIRST YEAR THE HOT ELECTRON AND ION DRIFT INTEGRATOR (HEIDI) WHICH MODELS THE INNER MAGNETOSPHERE KINETICS OF THE NEAR-EARTH PLASMA ENVIRONMENT WILL BE ADJUSTED FOR SATURN'S UNIQUE CONDITIONS INCLUDING NEW PLASMA SOURCE AND SINK TERMS. THECOUPLING OF HEIDI WITH THE BATS-R-US MHD GLOBAL MODEL ALREADY COMPLETED WITHIN THE SWMF FOR EARTH WILL BE TESTED WITH THE MODIFIED VERSION OF HEIDI FOR THE SPECIFIC CASE OF SATURN'S MAGNETOSPHERE. IN THE SECOND YEAR THE NEWLY COMBINED (KINETIC AND MHD) GLOBAL MODEL WILL BE COMPARED WITH THE PREVIOUS BATS-R-US (MHD) GLOBAL MODEL. IN THE THIRD YEAR OUR NEW MODEL OUTPUTS WILL BECOMPARED TO RESULTS FROM THE CASSINI MISSION INCLUDING ENERGETIC NEUTRAL ATOM DATA FROM THE MAGNETOSPHERIC IMAGING INSTRUMENT'S ION AND NEUTRAL CAMERA (MIMI-INCA) AND IN-SITU TIME DEPENDENT ENERGY DENSITY DISTRIBUTIONS. IF OUR PROPOSAL IS SUCCESSFUL WE WILL COMPLETE THE PROJECT FOLLOWING THE SUGGESTED TIMELINE AND PUBLISH THE WORK IN A PEER REVIEWED JOURNAL.THIS RESEARCH IS PARTICULARLY TIMELY GIVEN THE CASSINI-SOLSTICE MISSION IN ORBIT AROUND SATURN EXPECTED TO TERMINATE IN 2017. AFTER THIS DATE OUR OBSERVATION AND STUDY OF SATURN'S MAGNETOSPHERE WILL BE SECOND ONLY TO EARTH'S. THE STUDY OF THIS LARGE INFLUX OF DATA FROMTHE EXTENDED CASSINI MISSION IS CRITICAL TO OUR UNDERSTANDING OF SATURN'S MAGNETOSPHERE. OUR PROPOSED RESEARCH IS HIGHLY RELEVANT TO THE SCIENTIFIC GOALS OF THE CASSINI-HUYGENS MISSION AND WILL ADDRESS KEY GOALS FROM THE SCIENCE MISSION DIRECTORATE PLANETARY SCIENCEDIVISION EXPRESSED WITHIN THE 2014 NASA SCIENCE MISSION DIRECTORATE PLAN TO "EXPLORE AND OBSERVE THE OBJECTS IN THE SOLAR SYSTEM TO UNDERSTAND HOW THEY FORMED AND EVOLVE".
