Io

Monitor color and brightness changes of the surface

Full-disk images in four colors at low-to-moderate phase angles, for monitoring spatial and temporal variations in color and albedo. Surface monitoring frames are also useful for detecting plumes on the bright limb.

Full-disk images in six colors for compositional mapping which might reveal absorption features due to iron-rich silicates.

Images with Io illuminated by Jupitershine to search for night side brightenings and color changes associated with condensing frosts or other phenomena and very low phase angle observations to map regolith porosity variations.
