MESSENGER update?

Post #1by Dollan » 20.08.2004, 23:55

Just curious...

Since it launched a day late, is there an update somewhere for the MESSENGER mission that I might have missed (which is always probable)? Or is this delay insignificant?

I'm checking back for updates on JPL Horizons from time to time (haven't done it for a while, because I've been off the edge of the Internet for a couple of weeks) - I'll update and make an announcement on the forum if/when I've built a new xyz.

I've just queried xyz data from horizion. They start at 2004-08-03 07:15:00 (liftoff 07:15:56).
This positions the spacecraft above Papua New Guinea, distance to earth is about
1500km.
This is not exactly Florida. What is the problem?
- precision of horizon's data?
- precision of the position of earth (within celestia)?

I'm using the latest CVS celestia (a few days ago) on Linux SuSE 9.1

I've now updated the add-on using the new (post-launch) Horizons trajectory - it's available at http://www.lns.cornell.edu/~seb/celestia/hutchison/messenger.html
