Yalaing Terra time evolution. This figure shows the time evolution of Yalaing Terra as seen by Cassini ISS from 2010 August (before the changes occurred) through 2011 August 29. The ISS Basemap is a mosaic of the best ISS 0.938-micron images of each individual area over different flybys stitched together. High-cadence temporal resolution from ISS nicely complements the spectral resolution that VIMS affords. The earliest post-event observations show both highly darkened, moderately darkened, and brightened areas. The darkest areas revert to their original brightness over several months. The brightened areas revert more slowly, and moderately darkened areas turn bright and then slowly fade.
