Super-resolution mapping methods for icy moons

The main objective of this research proposal is to develop super-resolution mapping methods to increase the spatial resolution of surface maps of icy moons by combining all the overlapping observations acquired during a given planetary mission. We will first focus our efforts on developing, testing and validating the methods on Enceladus, using data from the Cassini-Huygens mission. These techniques will be particularly well adapted to increase the spatial resolution of the future observations of Jupiter’s icy moons by the JUICE mission. A main challenge for Ganymede will be to combine data acquired at very different spatial resolution during flybys and close orbits. The techniques developed in the present PhD project will allow us to optimize the spatial resolution and homogenize the regional and global mosaics in both visible and infrared domains.
