Celestia Forums

As I mentioned in a thread over on the Add-on releases sub-forum, I created a video showing the four Io flybys currently in the baseline trajectory for the Jupiter Europa Orbiter, NASA's mission to orbit Europa in the 2020s. I have created a small add-on with this trajectory. Please note a few things. First, the add-on uses timelines and spice kernels, so the latest version of Celestia is required. Second, only the Jupiter tour part of JEO mission is included as a spice file as that is the only one available online. The other two timeline segments simulate the high and low Europan orbits, but use Keplerian elements, rather than a trajectory file. The cruise to Jupiter, except for the five days before orbit insertion, is not included.

The other issue is that there is no model available online for Celestia for the Jupiter Europa Orbiter. In the above add-on and video, I use Cassini as a substitute. Would any modelers be willing to give this a try and create one? The website for the Europa/Jupiter System Mission and the Jupiter Europa Orbiter is at http://opfm.jpl.nasa.gov/europajupiters ... ssionejsm/ . If more perspective graphics of the spacecraft are needed, the E/PO at JPL might be able to post more such views online. A great resource for information on the spacecraft itself can be found in the Final Report for the Flagship Selection process last year: http://opfm.jpl.nasa.gov/files/JEO-Rpt_ ... 090203.pdf
