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. |

Do you have a date for when you expect to start taking the very first Jupiter data?

We will begin the Jupiter data collect at the very beginning of Jan 2007. The exact date
will not be known for some months as we refine planning an negotiate DSN contacts with JPL. If you want a best guess, put down Jan 10, with an error bar of +/-5 days. And by the way, TCM-3 did not change our reference course through the system. It trimed out residuals in our trajectory and put us closer to that exact reference course. |
