I sent a probe to the Jool system to recover lots of science from each of its moons. It's easily my most successful mission of all time; I haven't even gone to Bop yet and I've already got well over 1,000 points of science. I will have pictures later.
EDIT: Alright, now I've gone to Bop, and I have more than 2,200 science points. Probably not going to have pictures, because I crashed it into Bop's north pole.
