I just tried making a landing and return from Eve, realized there wasn't a chance yet. I'm going to have to develop something very advanced for that.
Since I'd quicksaved once while in orbit of Eve, I just adjusted my orbit, landed on Gilly, and returned from there.
Gilly has RIDICULOUSLY LOW gravity. I couldn't get my ship to actually land on it - I just got it to stop floating around at one point in time. Also I didn't try but I'll bet my kerbal can very easily reach escape velocity from Gilly with his RCS thrusters, if not just by jumping.
Returning from that mission yielded 804 science. :o
