I33 PPR Objectives

Here are the science objectives for Galileo's Photopolarimeter Radiometer (PPR) during I33:

  1. High-resolution nighttime mapping of temperatures at Prometheus, Marduk, and Pillan.
  2. High-resolution scans of nighttime equatorial temperatures, helping to constrain Io's total heat flow.
  3. Daytime temperature maps of Kanehekili- a major volcano never seen in close-up by Galileo before.
  4. A global map of daytime temperatures, at longitudes where this has never been done before- another constraint on Io's total heat flow.
