Speaking totally off-the-cuff because it's bedtime and I need to hurry, I think New Horizons is a much lighter spacecraft than Voyager; it doesn't have as much instrumentation. That will be a bigger limiting factor than the computing power, although the computers will allow it to record a lot more data for later playback, which will help maximize the returns in a way which Voyager couldn't quite do. NVRAM (flash memory, basically) has changed a lot of things in space processing. No more reliance on bulky mechanical tape drives with greatly reduced capacity and the ever-present possibility of motor failure.<br /><br />But by the same token, NH's sensor technology is decades ahead of Voyager. It may get a lot more out of its more limited instrument suite. Certainly camera technology has advanced tremendously. The Voyagers are equipped with vidicon tubes for imaging; NH has CCDs, which are definitely superior.<br /><br />One really fundamental limiting factor will be encounter speed, and there's nothing that can be done about that. NH is approaching Jupiter at fantastic speed. This is necessary in order to make the Pluto rendezvous. But it means that it will have significantly less time near Jupiter than either Voyager did, and that's a very hard limit. <div class="Discussion_UserSignature"> <p> </p><p><font color="#666699"><em>"People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint it's more like a big ball of wibbly wobbly . . . timey wimey . . . stuff."</em> -- The Tenth Doctor, "Blink"</font></p> </div>
