Hello, I work on this as an amateur and purely on my free time, I don't make any money with it, etc etc... Sometimes I have more free time, sometimes I'm busy. Currently I'm quite very busy, and in the forecoming weeks, with the CoVid restrictions being lifted I plan to move out to the city of Toulouse (according to my doctor, it won't last as contaminations will inevitably rise again, I have a "launch window" - she used those words - until mid-august).
Right now I can't release anything, its simply not ready. There is some more work required on the orbiter mesh, and I'll try to find time this week-end to start a .dll module for the lander (thanks to
@gattispilot for the mesh).
The rocket itself is in good progress, but some more work is required on the launch complex.
I'll try, as much as possible, to have some beta version ready for Tianwen's actual landing, that's the plan. But we don't have, AFAIK, a precise landing date yet.
On a sidenote, as a teacher the July-August months are mostly holidays, and at that point I should have an internet connection (hopefully optic fiber !!) and a "working station" all set up and ready. With the epidemic situation still not under control in France and people eager to share their germs on vacation locations, I expect a nerdy addon-developping summer. I can live with that ?
