At the risk of offending Titan-lovers here, I have to be honest and say that I'm glad Jupiter got the nod for this flagship mission, Don’t get me wrong; I love the Saturn system, and I love Titan too. What’s not to love about a planet-sized satellite that has its own atmosphere, coastlines, lakes and maybe ice volcanoes, too? And the proposed Titan mission sounds thrilling - who wouldn’t be thrilled to the point of blacking-out by the prospect of seeing pictures from a probe that has just splash-landed in one of Titan’s methane lakes, or from a balloon that is drifting over Titan’s plains - but that sounds like a very, very tough challenge to me. It will happen one day, I’m sure, but maybe not for another three decades… and I can’t wait that long! Jeez, I'm going to be 61 - sixty frakking one! - when the new Europa images start coming back. That's quite a depressing thought.
But I'm still excited at the prospect of seeing Europa again. It's one of my favourite worlds in the solar system. It’s captivated and fascinated me ever since I saw those first fuzzy Voyager images of it back in the days of Charlie’s Angels. (Oops, showing my age now!) and, spookily, I just finished reading John Varley's "Rolling Thunder" novel, a huge chunk of which is set on Europa. Reading it reminded me why I love its icebergs and ice cliffs; grooves and channels; crevices and crevasses. Voyager and Galileo showed us features on its mottled, fractured, colour-spattered surface that still make me shake my head in wonder. And those images, which are pretty good, were taken with old technology, cameras nowhere near as good as the kit we have today! Just imagine the stunning images we’ll see when EJSM starts taking pictures… we’ll zoom in on those jagged edged icebergs… see right into the fractures and pits and grooves… catch sunlight glinting off the vast ice plains… see Jupiter looming over Europa’s horizon, just as it’s been shown in space art for all these years… Of course, these pictures are all a long, long way ahead, and I can't help wondering what kind of world we’ll all be living in then. As I said, I’ll be 61 in 2026... how badly will Earth and mankind have been affected by global warming and economic hardship by then? Will China already have beaten the US to the Moon, and be in the process of training astronauts for a manned expedition to Mars? Will we have the first picture of an Earth-like extrasolar planet? Will we have detected a signal from another civilisation from deep space? It could literally be a New World by then, in so many ways. I don't know whether to be excited or frightened by that thought. But it's good to know we're planning the Next Great Mission. -------------------- |

Well said Stu! I had the same thrill from Voyager and Galileo. And on top of that there is Ganymede and Callisto... forgive me folks, but there is something very intriguing to me about the sublimating seltzer surface of Callisto, and the tectonics on Ganymede...... and how the freak does Callisto have an ocean when it formed too cold to differentiate.?

I agree. With four planet-sized moons, the surface area to explore is tremendous, and Galileo, while it was a noble salvage mission, barely could scratch the surface. I strongly favored this mission, although much of my bias comes from the fact that the Titan mission strikes me as more technically difficult (in the sense that it depends on more new technology), and is therefore more likely to be delayed.
