Click hum click hum go EUCLID-II's main tower as he runs several weather mapping algorithms.
There's been a mountain of incoming planetary data from the probes that EUCLID simply couldn't wait to get his processors on. Moon and small debris orbital trajectories, thermal maps, wind currents, atmospheric composition, etc. All of which has been stored and is awaiting analysis by scientists aboard.
As EUCLID-II tracks the wind patterns and thermal systems, he notices a small vortex located at planetary coordinates 34.112053,-117.876533 that reminds him of a pattern when he mapped sub-ice sheet ocean currents on Europa.
