Abstract:
The frozen volatiles on Pluto's surface, N2, CO and CH4, have long been expected to interact in complex ways as Pluto's distance from the sun and subsolar latitude vary over the course of a Pluto year. With the flyby of the New Horizons spacecraft by Pluto, we finally have a data that can help us understand this interaction more completely. Key datasets include spatially resolved surface spectra allowing the relation of composition to albedo; surface pressures; brightness temperatures of the winter longitudes at 4.2 cm; and detailed geology and geomorphology. These and other datasets will challenge and refine our previous understanding of Pluto's interacting surfaces and atmospheres.
