Just found out from today's issue of Science that NASA and ESA have decided to send the next outer solar system mission to Jupiter's moons Europa and Ganymede. Which is all very exciting, but it means there will be no ballooning on Titan in the next 30 years. And I was so looking forward to that one. Oh well let's hope these two missions come up with something to compensate that loss.
