What future space-probe mission are you most looking forwards to?

As in, a planned unmanned space-probe mission, so the Mars mission doesn't count. Missions that have already been launched don't count, so the Cassini data, Philae's later re-awakening, and the Pluto photographs don't count. Theoretical missions such as the Helium-3 harvester don't count either. But missions such as landing on an asteroid, Titan/Enceladus probes, and comet core sampling, do count. I'm most excited for the Titan/Enceladus probes. This has fascinated me for the longest of time! But the guy that's working on collecting samples from a comet... he's planning on using harpoons to do so. Let's hope he makes sure the propellant he uses actually works in a vacuum, unlike the folks at the ESA did with Philae... xD
