OUR MAIN GOAL IS TO DETERMINE THE ORIGIN OF THE NEAR-EARTH ASTEROIDS (NEAS) CURRENTLY TARGETED BY SPACECRAFT. AT PRESENT THESE ARE (101955) BENNU TARGET OF NASA S OSIRIS-REX (LAURETTA ET AL. 2010); (162173) RYUGU TARGET OF JAXA S HAYABUSA-2 (TSUDA ET AL. 2013); 2008 EV5 PROPOSED TARGET OF NASA S ASTEROID REDIRECT MISSION (ARM; MAZANEK ET AL. 2016); AND (65803) DIDYMOS TARGET OF THE JOINT ESA-NASA ASTEROID IMPACT&DEFLECTION ASSESSMENT DOUBLE ASTEROID REDIRECTION TEST (AIDA/DART) MISSION. DYNAMICAL MODELS AND SPECTRAL COMPARISONS SHOW THAT THESE FOUR SPACECRAFT-TARGETED NEAS WERE LIKELY DELIVERED FROM LOW-INCLINATION (I<12 ) INNER-ASTEROID BELT (2.15<A<2.5) POPULATIONS INCLUDING ASTEROID FAMILIES AND THE BACKGROUND (E.G. CAMPINS ET AL. 2010 2013; BOTTKE ET AL. 2015). OUR PROPOSED ASTEROID SPECTROSCOPIC STUDIES WILL BUILD ON OUR PROVEN METHODS AND INITIAL ACHIEVEMENTS AND WILL PROVIDE A FRAMEWORK FOR INTERPRETING RESULTS FROM OSIRIS-REX HAYABUSA-2 ARM AND AIDA/DART. IN ADDITION THERE IS A GROWING INTEREST IN ASTEROIDAL RESOURCES INCLUDING IN-SITU RESOURCE UTILIZATION (ISRU) AND NEAS ARE IDEAL FOR IMPLEMENTING ISRU CAPABILITIES. OUR SPECTROSCOPIC CHARACTERIZATION IS ALREADY HELPING TO IDENTIFY NEAS WITH THE DESIRED COMPOSITION FOR ISRU SUCH AS THOSE RICH IN HYDRATED MINERALS AND METALS (E.G. LANDSMAN ET AL. 2015). THREE OF THE FOUR SPACECRAFT-TARGETED NEA S (BENNU RYUGU AND 2008 EV5) ARE PRIMITIVE ASTEROIDS (SPECTRAL TYPE B AND C). AS OF EARLY 2016 SIX LOW-ALBEDO (I.E. PRIMITIVE) ASTEROID FAMILIES HAVE BEEN IDENTIFIED IN THE LOW-INCLINATION REGION OF THE INNER BELT (NESVORNY ET AL. 2015). WE HAVE ALREADY CHARACTERIZED THE POLANA-EULALIA AND ERIGONE FAMILIES USING VISIBLE AND NEAR-INFRARED SPECTROSCOPY. OUR INITIAL RESULTS ARE TANTALIZING; WE HAVE FOUND SIGNIFICANT SPECTRAL HOMOGENEITY WITHIN THE POLANA-EULALIA POPULATION AND SHARP DIFFERENCES BETWEEN THE ERIGONE AND POLANA-EULALIA FAMILIES. MORE SPECIFICALLY WE (DE LE N ET AL. 2016; PINILLA-ALONSO ET AL. 2016) SHOWED THAT THE POLANA-EULALIA COMPLEX IS SPECTRALLY HOMOGENEOUS AND THAT THE DYNAMICAL AND COLLISIONAL COMPLEXITY OF THIS POPULATION (E.G. BOTTKE 2015; DYKHUIS AND GREENBERG 2015; WALSH ET AL. 2013) DOES NOT TRANSLATE INTO SPECTRAL DIVERSITY. IN MORATE ET AL. (2016) WE STUDIED THE VISIBLE SPECTRA OF ERIGONE ASTEROIDS AND FOUND THAT THE DISTRIBUTION OF TAXONOMIC CLASSES WITHIN THE ERIGONE FAMILY DIFFERS SIGNIFICANTLY FROM THAT OF POLANA-EULALIA. INTERESTINGLY THE MAJORITY OF THE ERIGONES SHOW A 0.7- M HYDRATION FEATURE WHILE THE POLANAS DO NOT. IT HAS BEEN SUGGESTED THAT THE PAUCITY OF HYDRATION FEATURES IN THE POLANAS MAY BE RELATED TO THE FAMILY S AGE OUR PROPOSED OBSERVATIONS WILL HELP TEST THIS HYPOTHESIS BY STUDYING AND COMPARING PRIMITIVE FAMILIES WITH A RANGE OF AGES. WE HAVE ALSO FOUND THAT THE SPECTRA AND THE ORBITAL ELEMENTS OF ASTEROIDS BENNU RYUGU AND 2008 EV5 ARE COMPATIBLE WITH AN ORIGIN IN THESE FAMILIES; HOWEVER THESE ARE ONLY PRELIMINARY RESULTS. MANY DETAILS NEED TO BE RESOLVED AND AT LEAST FOUR INNER-BELT POPULATIONS (THREE FAMILIES AND THE LOW-ALBEDO AND LOW-INCLINATION BACKGROUND) NEED TO BE STUDIED IN DETAIL. THE WORK PROPOSED IS WITHIN THE SCOPE OF THE PLANETARY ASTRONOMY AND NEAR-EARTH OBJECT OBSERVATIONS (NEOO) PROGRAM ELEMENTS AND THESE ARE MOST APPROPRIATE ELEMENTS FOR THE WORK PROPOSED FOR THE FOLLOWING REASONS: 1. NEW SOLAR SYSTEM OBSERVATIONS: THE PRIMARY ELEMENT OF THIS PROPOSAL IS A SPECTROSCOPIC SURVEY OF INNER-BELT ASTEROIDS. 2. SUPPORT OF SPACECRAFT MISSIONS: THE PROPOSED WORK DIRECTLY SUPPORTS FOUR NASA AND INTERNATIONAL SPACECRAFT MISSIONS. OUR MAIN GOALS ARE TO DETERMINE THE MAIN-BELT ORIGINS OF THREE NEAS TARGETED BY NASA MISSIONS: BENNU (OSIRIS-REX) 2008 EV5 (ARM) AND DIDYMOS (AIDA/DART). WE ALSO INCLUDE ASTEROID RYUGU THE TARGET OF JAXA S HAYABUSA 2 MISSION
