Neither Mars nor Enceladus is waste of "millions", science costs billions and decades to go to outer system planets to usefully increase study astrobiology of our system. Both Mars and Enceladus are habitable, on Mars in the watery crust where early evolved life may still exist but its habitable history is interesting too!
I couldn't agree with you more. I was just being snarky regarding ESA's apparent lack of ambition or urgency as compared to NASA, and more starkly, to private efforts in the past 5-10 years. A lot of bureaucracy to trudge through when trying to align the budgets of all the EU's contributing member states.
Mars, Enceladus, Europa, and Titan (among many other targets, of course) are all worthy of momentous efforts to explore their secrets in depth. I'm simply impatient, even though I'm admittedly doing nothing to contribute to space exploration beyond peering through my civilian-grade telescope at home.
