Here's a scenerio file that starts the day before Phoenix lands on Mars. The Delta Glider is placed on Phoenix's trajectory. If you run it through, the Delta Glider passes through Mars' atmosphere near its North Pole, and then escapes. See if you can pilot it to a landing. Trajectory data is from JPL Horizons.

Here's a series of screenshots that I snapped from a number of selected angles as I ran Brian Jones' excellent Phoenix Mars Mission package for Orbiter. Good job Brian!

Jettison of the solar panels WAY to early, however the rest of the vid is nice!

Yeah, I know. The solar package contained the observation cameras and they would be out of sight of the lander at that distance.
 
Hey folks!
nice to see people having some fun with the add-on :-)

Here's a scenario that includes the MRO, which is pretty much overhead at the landing site when Phoenix arrives. I haven't tried it yet, but it might be fun to use Artlav's TelescopeMFD to observe the reentry.

Would be nice to have MEX (there's an add-on out there somewhere, but not with BeagleII I think) and Mars Odyssey (not available for Orbiter as far as I know), which are also involved in monitoring the Phoenix EDL.

All the best,
Brian
