ASTEROID FAMILIES ARE GROUPINGS OF ASTEROIDS IN ORBITAL ELEMENT SPACE THAT FORMED FROM A SINGLE PARENT BODY AT SOME POINT IN THE PAST. THE THEMIS FAMILY HAS ATTRACTED PARTICULAR INTEREST IN RECENT YEARS. THREE CURRENTLY-KNOWN MAIN-BELT COMETS (MBCS) WHOSE ACTIVITY MAY BE DRIVEN BY THE SUBLIMATION OF VOLATILE ICE ARE THEMIS FAMILY MEMBERS. DETECTIONS OF SURFACE ICE ON TWO LARGE MEMBERS OF THE FAMILY HAVE ALSO BEEN REPORTED. SINCE ASTEROID FAMILY MEMBERS ARE BELIEVED TO BE COMPOSITIONALLY SIMILAR THESE FINDINGS INDICATE THAT ICE COULD BE WIDESPREAD WITHIN THE FAMILY. WE SEEK TO UNDERSTAND HOW ICE-BEARING OBJECTS FROM THE THEMIS FAMILY MIGHT BE DISTRIBUTED AND TRANSPORTED THROUGHOUT THE MAIN BELT AND TO THE NEAR-EARTH OBJECT POPULATION. THESE DYNAMICAL STUDIES WILL THEN BE COUPLED WITH THEORETICAL THERMAL MODELING TO UNDERSTAND THE FATE OF ICE IN THESE OBJECTS. TWO OF THE MBCS IN THE THEMIS FAMILY BELONG TO YOUNG (<10 MYR) SUB-FAMILIES. THIS IS INTRIGUING SINCE THE RECENT FORMATION OF SUBFAMILIES COULD BE A PLAUSIBLE MEANS FOR PRODUCING "FRESH" FRAGMENTS WHERE ICE LIES AT OR JUST BELOW THE SURFACE MAKING MBC-LIKE ACTIVITY MUCH MORE LIKELY. WE WILL CONDUCT A SYSTEMATIC SEARCH FOR MORE THEMIS SUB-FAMILIES. ANY NEW SUB-FAMILY WILL BE STUDIED TO ASCERTAIN ITS AGE AND PHYSICAL CHARACTERISTICS. WE WILL ALSO INSPECT AVAILABLE ARCHIVAL IMAGES OF NEW SUB-FAMILY MEMBERS TO SEARCH FOR PREVIOUSLY UNRECOGNIZED ACTIVITY IN AN EFFORT TO IDENTIFY NEW MBCS. WE WILL ALSO INVESTIGATE THE LONG-TERM DYNAMICAL EVOLUTION OF ASTEROIDS FROM THE THEMIS FAMILY WITH A PARTICULAR FOCUS ON IDENTIFYING PATHWAYS BY WHICH MEMBERS CAN EXIT THE FAMILY VIA RESONANCES OR NON-GRAVITATIONAL EFFECTS AND ASCERTAINING THE PROBABLE ABUNDANCE AND DYNAMICAL PROPERTIES OF SUCH OBJECTS. IT HAS BEEN SUGGESTED THAT A FOURTH MBC COULD HAVE ONCE BEEN A THEMIS MEMBER DESPITE ITS CURRENTLY HIGH ECCENTRICITY. WE WILL INVESTIGATE THIS HYPOTHESIS USING NUMERICAL INTEGRATIONS OF MEMBERS OF THE THEMIS FAMILY INCLUDING BOTH GRAVITATIONAL AND NON-GRAVITATIONAL FORCES TO DETERMINE WHETHER OTHER MAIN-BELT ASTEROIDS OR EVEN NEAR-EARTH OBJECTS COULD BE FORMER THEMIS FAMILY MEMBERS. USING THESE DYNAMICAL RESULTS WE WILL DEVELOP THERMAL MODELS OF ICE DEPLETION IN THEMIS ASTEROIDS AS THEY EITHER REMAIN IN THE MAIN BELT ACCOUNTING FOR BOTH THERMAL AND COLLISIONAL PROCESSES OR TRANSITION FROM THE MAIN BELT TO NEAR-EARTH SPACE ACCOUNTING FOR CHANGING ENVIRONMENTAL CONDITIONS AS THEY EVOLVE. IN PARTICULAR WE ARE INTERESTED IN DETERMINING IF ICE COULD STILL PERSIST IN NEOS WITH OUTER ASTEROID BELT ORIGINS. WE WILL BUILD ON EXISTING THERMAL AND ICE EVOLUTION MODELS OF THE NEAR-SURFACE AND COUPLE THEM WITH A 3D MODEL FOR THE INTERIOR OF THE BODY. THIS HIGHLY INTERDISCIPLINARY WORK IS RELEVANT TO NASA S SOLAR SYSTEM WORKINGS PROGRAM IN NUMEROUS WAYS. WE WILL STUDY GRAVITATIONAL AND NON-GRAVITATIONAL EFFECTS ON ASTEROIDS WITHIN AND WITHOUT AN ASTEROID FAMILY AND HOW THEY AFFECT ORBITAL CHARACTERISTICS AND STABILITY. WE WILL ALSO SEARCH FOR YOUNG SUB-FAMILIES WITHIN THE THEMIS FAMILY WHOSE FORMATION EVENTS ARE POSSIBLE SOURCES OF INTERPLANETARY DUST ANOTHER TOPIC OF INTEREST FOR THE SSW PROGRAM AND STUDY THE LONG-TERM DYNAMICAL EVOLUTION OF BOTH THE MAIN FAMILY AND ITS SUB-FAMILIES. AS PART OF OUR EFFORTS TO PHYSICALLY CHARACTERIZE YOUNG ASTEROID FAMILIES WE WILL ALSO ANALYZE AND INTERPRET EXISTING OBSERVATIONS OF SOLAR SYSTEM OBJECTS. FINALLY WE WILL INVESTIGATE THE PHYSICAL EVOLUTION OF VOLATILE MATERIAL (PARTICULARLY WATER ICE) IN THE INTERIORS OF MINOR BODIES VIA THEORETICAL MODELING WHICH ALIGNS WITH THE SSW PROGRAM GOAL TO STUDY THE INTERNAL STRUCTURE OF SOLAR SYSTEM OBJECTS AND UNDERSTAND THE PHYSICAL PROCESSES THAT OCCUR WITHIN THESE STRUCTURES AND IS ALSO ALIGNED WITH NASA S STRATEGIC INTEREST IN ASTEROID RESOURCE EXPLOITATION.
