I find Europa fascinating but unfortunately I think the lack of missions is less about interest and more about feasibility. On earth we rarely drill more than 2-3km down. The Russians did 12km once in Antarctica. With Europa we are looking at 20km+ of multiple layers of exotic Europan ice with composition and properties we know very little about, have zero experience with. Not to mention the immense distance, time lags and hostility of the environment. Drilling on earth is dangerous and difficult and failure prone as it is. How do we learn to do this? How many missions and failures are required?
