Yes, we'll need those RCS thrusters. I'd like to do the coding for the lander, because I want to implement stuff such as thrust-vectoring, and I'd like to avoid a dependancy with VB (that I like a lot, that's not the issue). Also I'll need to figure out some landing autopilot, probably going to be quite a challenge but should be interesting. AFAIK the RCS thrusters are 150N each and the main engine can throttle between 1500N and 7500N. The powered descent is not longer than 90 seconds. I'm not 100% sure about the main engine TVC ability, I have to find more sources about it.

According to Wiki : 20x 250N + 6x 25N thrusters for the lander attitude control.

No thanks, I prefer to "start from a blank page". I have some templates ready.

Can't find any real info on the lander main engine except the thrust, if you find anything I'm interested.

Got the Rover mesh built. Working on coding her. The solar panels are the same design except the rear one are angled at 120 degrees. Hopefully pictures soon. Not got her to run in d3d9 yet though

Things I need to redo. It seems the top has panels also.. the position of the flag? The subsurface radar ch2. seems to be deeper

Look cool. I think the solar panels are angled up, judging by that illustration.
But it would make more sense if they were angled down to maximize morning/afternoon sun.

Anyway, they seem to be able to move... I wonder if it has something to do with dust accumulation.

Yes. I can have them angled up. Right now they are 180 degrees so maybe 160?

I think its some kind of "failsafe", in case it hits a big rock. The "upwards" shape allows better clearance and probably to avoid getting stucked too badly, especially on uneven terrain.

When I run the scenario when loading the start up screen locks up. It never loads. I have to shut orbiter down and restart. I tried running it in debug. It hit some break point and I hit continue and same thing.

The Tianwen-1 Mars Lander is scheduled to attempt to land on Mars around May 17th. If successful, would deploy the Zhurong rover to the surface.

I placed the rover at the bases. And we have rover sub. Using the hi def terrain.

But now I have a major problem. I noticed it when I started to redo the dialogue box for the HGA,mast,......

Now on all my dialogue box projects I get this:

Severity Code Description Project Path File Line Suppression State
Error RC1015 cannot open include file 'afxres.h'. TRover D:\Orbiter2016\Orbitersdk\samples\Trover D:\Orbiter2016\Orbitersdk\samples\Trover\MSL.rc 10

Thats a standard problem with VC++, it comes from old MFC code. You can now either install MFC again. Or just replace
Code:
#include "afxres.h"
by
Code:
#include "windows.h"

I prefer the latter solution, if you really want to do me a favor, you can check if the C++ binding for WPF can be used in Orbiter... I have no time for this experiment.

Thanks. I saw that. But when I did that now I get this:

Severity Code Description Project Path File Line Suppression State
Error RC2104 undefined keyword or key name: IDC_STATIC TRover D:\Orbiter2016\Orbitersdk\samples\Trover D:\Orbiter2016\Orbitersdk\samples\Trover\MSL.rc 33
I might just try to figure out how to install MFC

I reinstall or install the MFC and it seems to be working:) Thanks

I guess on the rover the touchdown points need to be raised so the rover sits on the ground

Yes, or the spring forces have to be defined different. As I noticed, these forces have quite some effect, when you go from landed to free-flight...

I think the last thing to animate is the dish at the front. I am thinking it rotates up/down and left and right.

TD point need to be adjusted for Mars terrain
