While working on the Galileo + IUS model (See "Deployment from Shuttle" topic, page 2) I realised that the existing galileo model was slightly innacurate from launch to Jupiter orbit insertion. The Jupiter atmospheric probe was missing! So, i've modified the existing Galileo model and added it in. Download from http://homepage.eircom.net/~jackhiggins/celestia/ (It's number 19 in Spacecraft) but here are 2 quick screenshots first.
The download zip also includes an ssc segment to replace the existing galileo section in solarsys.ssc. The galileo + probe model will change to the normal galileo model at exactly 05:41:00 UTC on the 13th July, 1995, the moment the galileo probe xyz trajectory starts up.
