The Mars Express realtime simulation at http://www.dmuller.net/mex now includes trajectory information on the spacecrafts orbit around Mars on a trial basis. Unfortunately I have problems uploading data for Phobos so at present information regarding distance etc. to Phobos cannot be displayed. Working on it.
Voyager 2 trajectory data has been adjusted to match output by the Voyager 2 team tweets. Data provided in JPL’s Horizons system was about 2 light seconds (~600,000km) off.
The realtime simulation of the Cassini mission has been updated to show the upcoming close encounters with Rhea and Helene (March 2 & 3). Unfortunately, the solar system simulator does not have Helene in it so I cannot link in the usual simulated views.
Whilst upgrading the background processes to allow for the upcoming Cassini multiple flybys, I have also fixed some errors that occurred in missions where there is no distance flown information available.
The Cassini mission had its extended-extended mission approved and will run until 15 Sep 2017 when it will be deliberately crashed into Saturn (to protect Titan from Earthlings contamination). I have uploaded the new timeline as well as the general trajectory (the data that the system will fall back on when the segment trajectory data runs out). The latest segment trajectory is up as well and runs to early March 2010. Go Cassini!
The latest Cassini sequence trajectory data has been uploaded and will be used until it expires on 04 Feb 2010. After that date, the data will fallback to the base data until the new trajectory sequence is available.
Dawn cruise sequence DC036 has been uploaded as well and will take over on 08 Feb 2010.
