The Jupiter Icy Moons Explorer (JUICE) is a flagship space mission led by the European Space Agency (ESA), launched on 14 April 2023. Its primary goal is to explore Jupiter and its three largest ocean-bearing moons – Ganymede, Europa, and Callisto – with emphasis on investigating their icy shells, subsurface oceans, surface geology, and potential habitability. JUICE will arrive at Jupiter in July 2031 and conduct at least four years of scientific observations, including detailed orbiting of Ganymede.

Among JUICE’s scientific instrumentation is the JANUS camera (Jovis, Amorum ac Natorum Undique Scrutator), a high-resolution imager that captures detailed surface features of Jupiter’s moons. JANUS acquires multispectral context images of the surfaces of Ganymede and Callisto, enabling the identification and mapping of color variations related to surface composition with spatial resolutions unmatched by other JUICE instruments. Additionally, JANUS targets selected regions at the highest spatial resolution to study physical surface properties in detail. The project aims at supporting the operational activities of JANUS and is divided in three sub-projects:

 

 

1.  Cryovolcanic Processes and Topographic Modeling
   
   
2. Software Development for Observation 
   
   
3. SimulationImage Database Development
