Abstract:
We examine the combined Pluto/Charon system using all SIRTF
instruments.  The IRS observations generally use the Long Lo module.
When used in conjunction with IRAC and MIPS photometry observations,
these observations will provide us with composition, albedo, and
thermal properties information.  Pluto is observed at 8 equally spaced
observer sub-longitudes, and follow-up observations 1 and 2 yr after
the initial lightcurve measurements are planned.
