WE PROPOSE TO MEASURE THE PROPERTIES OF INTERSTELLAR DUST IN A HOLISITIC MANNER THAT INCORPORATES CONSTRAINTS FROM A DIVERSE RANGE OF STATE-OF-THE-ART OBSERVATIONS. THESE ARE THE DIMMING OF STARLIGHT INDEPENDENT MEASUREMENTS OF THE PROPERTIES OF STARS ABSORPTION FROM DIFFUSE INTERSTELLAR BANDS AND THE MICROWAVE EMISSION OF THE DUST. PREVIOUS MEASUREMENTS OF THE DIMMING OF STARLIGHT REFERRED TO IN THE LITERATURE AS THE DUST EXTINCTION CURVE HAVE ASSUMED INTRINSIC PROPERTIES FOR EITHER STARS OR OTHER OBJECTS SELECTED AS CALIBRATORS. THESE ASSUMPTIONS WERE IN TURN OFTEN CALIBRATED BY PRIOR LITERATURE STUDIES WHICH THEMSELVES ASSUMED AN EXTINCTION CURVE. OUR PROPOSED PROGRAM WILL BE THE FIRST TO JOINTLY AND SIMULTANEOUSLY MODEL BOTH SETS OF PARAMETERS. THIS BREAKTHROUGH IS ENABLED BY THE UNPRECEDENTED ABUNDANCE OF PANCHROMATIC PHOTOMETRIC DATA FROM BOTH NASA-SUPPORTED MISSIONS (GALEX 2MASS WISE) AND OTHER COMPLEMENTARY FACILITIES. OUR PLANNED ANALYSIS IS SPLIT INTO FOUR COMPONENTS SPREAD OVER TWO YEARS. WE WILL FIRST JOINTLY MODEL THE EXTINCTION CURVE AND THE COLOR-TEMPERATURE-SURFACE BRIGHTNESS RELATION IN THE 561 000+ BRIGHT NEARBY STARS WITH PARALLAXES FROM GAIA ATMOSPHERIC PARAMETER ESTIMATES FROM GALAH AND PHOTOMETRY FROM A SLEW OF SURVEYS SPANNING THE ULTRAVIOLET OPTICAL AND NEAR-INFRARED WAVELENGTHS. THIS WILL YIELD THE MOST ROBUST MEASURE OF THE DUST EXTINCTION CURVE AND ITS VARIATIONS WHILE SIMULTANEOUSLY YIELDING A DEFINITIVE ASSESSMENT OF STELLAR MODELS' RELIABILITY IN PREDICTING THE INTRINSIC COLORS OF STARS. IN THE SECOND PHASE OF OUR PROGRAM WE WILL COMPARE THESE EXTINCTION MEASUREMENTS TO THE EQUIVALENT WIDTHS OF UP TO 12 DIFFUSE INTERSTELLAR BANDS. THESE HAVE THE PROSPECT OF ENABLING DUST EXTINCTION ESTIMATES THAT ARE INDEPENDENT OF THE PROPERTIES OF THE SOURCE AND CAN THUS BE APPLIED TO OBJECTS FOR WHICH THE UNEXTINGUISHED COLOR AND BRIGHTNESS ARE NOT KNOWN. IN THE THIRD PHASE WE WILL EXTEND OUR ANALYSIS TO STARS WITH ASTEROSEISMICALLY DETERMINED RADII IN THE KEPLER AND K2 FIELDS. THIS WILL ENABLE BOTH AN INDEPENDENT VALIDATION OF OUR PRIOR RESULTS AND MORE PRECISE FUTURE INVESTIGATIONS OF THOSE STARS AND THE PLANETS THAT MANY OF THEM ARE KNOWN TO HOST. FINALLY WE WILL COMPARE OUR MEASUREMENTS OF DUST EXTINCTION TO THE MICROWAVE EMISSION OF DUST MEASURED BY THE PLANCK SATELLITE YIELDING THE MOST SENSITIVE STUDY OF THE ASSOCIATION BETWEEN DUST EXTINCTION AND EMISSION. THE PARAMETERIZATION OF DUST EXTINCTION IS A PROBLEM FOR MANY AREAS OF MODERN ASTRONOMY AND ASTROPHYSICS. HERE WE MENTION FOUR EXAMPLES. THE FIRST IS THAT THE PROPERTIES OF DUST EXTINCTION ARE A SENSITIVE FUNCTION OF THE DUST GRAINS THEMSELVES WHICH CAN INFORM STUDIES OF THE PHYSICS AND CHEMISTRY OF INTERSTELLAR MEDIUM FROM WHICH STARS AND EVENTUALLY PLANETS ARE BORN. THE SECOND IS THAT THE EXTINCTION CURVE TOWARD THE INNER MILKY WAY IS PARTICULARLY ANOMALOUS WHICH IS A SOURCE OF UNCERTAINTY FOR STUDIES OF EXTRASOLAR PLANETS (FROM MICROLENSING) AND THE PROPERTIES OF MANY OF THE OLDEST AND MOST CHEMICALLY PECULIAR STARS IN THE GALAXY. THE THIRD IS THAT EXTINCTION CURVE MEASUREMENTS OF TYPE IA SUPERNOVAE ARE SIGNIFICANTLY OFFSET FROM MEASUREMENTS OF THE EXTINCTION CURVE WITHIN THE MILKY WAY. THAT IS AMONG THE LARGEST SOURCE OF UNCERTAINTY IN THEIR ESTIMATES OF COSMOLOGICAL PARAMETERS AND IT WOULD BE WORTH KNOWING HOW MUCH OF THE BIAS IS SIMPLY DUE TO AN ERROR IN THE ASSUMPTION OF THE MILKY WAY EXTINCTION CURVE. THESE THREE AREAS ADDRESS KEY NASA PRIORITIES OF HOW THE UNIVERSE FORMED AND EVOLVED AND THE ORIGINS OF STARS AND LIFE. FINALLY THIS ANALYSIS WILL AUGMENT UNDERSTANDING OF THE UTILIZED NASA DATASETS. THE PROBLEM OF ACCOUNTING FOR DUST EXTINCTION IS UBIQUITOUS TO THE VARIOUS SUBFIELDS OF ASTRONOMY. THOUGH THE ISSUE IS CHALLENGING IT IS ALSO TRACTABLE. WITH THE UNPRECEDENTED ABUNDANCE OF AVAILABLE DATA AND NASA S SUPPORT PERMITTING WE WILL HAVE THE NECESSARY TOOLS TO RESOLVE THIS ISSUE.
