We took advantage of the extraordinary excursion in solar phase angles obtained by the Cassini orbiter and the wavelength range of the VIMS instrument (0.34 - 5 microns) to produce a map of the bolometric Bond albedo for the entire surface of Iapetus. Previous albedo maps of the icy satellites of Saturn from Voyager exhibit less range in wavelength and are based on more limited solar phase angle coverage. The phase angle coverage of Cassini allowed phase curves to be built for each wavelength and for the trailing and leading sides of Iapetus and computation of the corresponding phase integrals. Maps of normal reflectance were produced using a Lommel-Seeliger photometric function, which has been shown previously to apply to the leading and trailing sides of Iapetus. We then produced maps of geometric albedo, which corresponds to the normal reflectance for Iapetus, and multiplied each pixel by the phase integral for that region to produce separate maps of Bond albedo for each wavelength. Integration of each pixel in the map over wavelength, with the proper weighting of each wavelength by the solar flux at that wavelength, and normalization by the integral solar flux produced the bolometric Bond albedo map. We will discuss the implications of our map on the energy balance, surface composition, and volatile transport on Iapetus.
