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. |

Good heavens. I completely overlooked that paper -- I was under the impression that their existence was first announced at this year's meeting!

Good heavens. I completely overlooked that paper -- I was under the impression that their existence was first announced at this year's meeting! Actually the "crop circles" are seen better by near-terminator imaging than by stereo- it's the near-terminator imaging that we'll be concentrating on with New Horizons. They are indeed strange and wonderful features so I hope we can shed some more light on them (so to speak). On another topic, we had a meeting last week where we thrashed out the details of the Jupiter encounter timeline- we now have a time-ordered listing of science observations, calibration observations, and DSN passes that seems to satisfy nearly all of our science goals. There will still be fine-tuning, but we finally have a pretty clear idea of what we'll be doing, and when. It feels like we've passed an important milestone. It look's like we'll be able to include a few of Hendric's "Kodak Moments", too, though we haven't made any final decisions on which ones. John. |

I hope you'll be able to get the one of Io and Europa passing by each other, and the ones with the moons grazing Jupiter's limb. -------------------- Space Enthusiast Richard Hendricks
