I think the Jupiter encounter deserves its own thread.
I've just been taking a first look at the Jupiter encounter geometry. You can do the same using Mark Showalter's excellent on-line ephemeris tools at the PDS rings node, which by good fortune happens to include a New Horizons ephemeris (calculated over a year ago) for our actual launch date, January 19th. We'll have an updated ephemeris soon, but this one's already good enough for planning. As Roby72 noted in the Star 48 thread, the satellites are (annoyingly) all on the opposite side of Jupiter at closest approach. We'll still get good views of all sides of Io because Io rotates in only 1.8 days and we'll be pretty close to Jupiter for that long. We'll get fairly good coverage on Europa too, for the same reason. But we won't get very close to Ganymede or Callisto. Luckily Io is our highest priority satellite target and Europa is next, so we'll do OK. |

That subject has been discussed earlier in this very thread. Alas, NH (despite Alan Stern's earlier hopes, as repeatedly expressed to me) will be considerably farther from Himalia than Cassini was, and won't be anywhere near any of the other irregular satellites either -- nor will it come anywhere near a Centaur (another of his long-shot hopes).

I think my question was unclear. I was referring to a possible telescopic search to see if anything small is lurking near NH's path, similar to what will be done for the Kuiper Belt. -------------------- |
