IN THESE TWO ASTEROID CHARACTERIZATION PROGRAMS WE WILL USE NEAR-INFRARED SPECTRA OBTAINED BY THE NASA INFRARED TELESCOPE FACILITY (IRTF) TO CHARACTERIZE THE COMPOSITIONS OF NEAR-EARTH AND MAIN BELT ASTEROIDS. IN A SEARCH FOR A DIFFERENTIATED ASTEROID FAMILY WE SEEK TO ADDRESS THE MISSING MANTLE PROBLEM: THE LACK OF OBSERVABLE ASTEROID MANTLE MATERIAL IN THE MAIN BELT. WE WILL USE VISIBLE AND NEAR-INFRARED SPECTROSCOPY TO STUDY THE MINERALOGY OF MASSALIA MERXIA AND AGNIA FAMILY MEMBERS. WE WILL SEARCH FOR SIGNATURES OF DIFFERENTIATION AND USE THE RESULTS OF OUR SEARCH TO CONSTRAIN THE MODELS FOR THE FORMATION AND THERMAL EVOLUTION FOR EARLY PLANETESIMALS. OBSERVATIONS FOR THIS PROGRAM WERE COMPLETED IN JANUARY 2017. REDUCTIONS AND ANALYSIS ARE UNDERWAY. FOR CHARACTERIZATION OF THE NEAR-EARTH ASTEROID POPULATION USING MITUH- IRTF JOINT CAMPAIGN SPECTRA WE WILL USE THE LARGE PUBLIC JOINT CAMPAIGN SPECTRAL DATABASE TO INVESTIGATE THE COMPOSITIONS OF VARIOUS NEAR-EARTH OBJECTS. LARGE-SCALE SPECTRAL ANALYSES OF THE NEAR-EARTH ASTEROID POPULATION CAN SHED LIGHT ON A VARIETY OF TOPICS INCLUDING THE DISTRIBUTION OF TAXONOMIC CLASSES THROUGHOUT NEAR-EARTH SPACE AND THE SOURCE REGIONS FOR VARIOUS POPULATIONS (SUCH AS TAXONOMIC CLASSES AND METEORITE ANALOGS).
