Title: Pluto's volatile distribution from speckle imaging

Abstract: Howell et al. (2012) separated Pluto and Charon with the speckle imager, DSSI, and measured their diameters. We propose to build on this work, to map the volatiles on Pluto, by taking more exposures, observing in four filters designed to measure Pluto's albedo, color, and CH_4 distribution, and observing multiple faces on Pluto. This will help us study Pluto's migrating frosts as Pluto leaves the sun, and as its summer pole becomes more directly illuminated. We compare results back to HST maps in 1994 and 2002/2003 and forward to New Horizons maps in 2015 and future ground-based maps in 2015 or beyond.
