Awesome thread!! Potential ASTR minor (have taken 2 courses, not sure how for I want to go). One of those courses was "Collisions in Space" which was incredible.
My fav object in the solar system besides Earth is Europa. I am confident it has life and I wish both Europa and Titan had the funding allocations to get missions underway SOON. The technology for Europa's drill is under way but I know nothing is set in stone for the mission itself (which got the go-ahead over Titan but still). It'll take 7 yrs to get there, so if this thing takes 10 years to happen it could be like 25 years until we see what becomes of Europa. Therefore; sooner please!
