There are some very interesting - and cool - missions in this thread. Anyway, THE CHALLENGE: Send Val to Vall in a single stage to Vall spaceplane. Feel free to stop by Laythe (please do), use gravity assists, go crazy. ISRU's are allowed, but it must be a single launch - no refueling from the Capricorn, @Snark. It can be multiple parts, and can be assembled in orbit. It would be nice if it can return on a single stage, too. However, it doesn't have to be single stage from the Joolian system, just to it.
