I can’t seem to get the rover moving - Idk why .
Was there another release of the rover ? I recall there was another one ?
Maybe I need some add ons / modules that I don’t have &#55358;&#56596;

Which scn?

So I did find a new model of the MArs 2020 rover. But I am not able to export from blender to 3ds.

https://nasa3d.arc.nasa.gov/detail/perseverance-glb

I have the MSL&COPTER.scn of 6 Aug 2019 and MSL2020.scn of 16 Aug 2019

Do I have wrong ones ? I seem to be able to hit 1 and 2 to turn on off the laser. but no moving.

So in the rover and press F1 you should see this view.

See on the left when you press up arrow on the keypad it should change to forward gear.
Then +/- increase speed

So got a new mesh of it but meshwizard doesn't load. So I may need to rebuilt it from scratch

Yes Unless someone else does.

I need to get the shuttle released first

hmmm I see I see.. how very strange, when I PRESS the up button (up arrow).. no matter how long, and how much I cannot shift the gear to Fwd thrust. Its as if, the command is not obeyed. Did anyone experience this before me ? Or do I have a corrupted system ? thanks for ur patience.

I am using a windows on crossover on a Mac. But I haven't encountered any problem what so ever in any scenarios so far ,except this one.

So does it show Neutral gear? 8 on keypad should be forward and 2 reverse

I can confirm that even when pressing 8 or 2. It doesn't shift or change the gear

Maybe I redownload. I don't think that is the issue.

I used Ctrl. + for the throttle and that worked! :thumbup:

Thanks, John!

I'm driving it fine! I have a picture on my desktop! I'm using Windows 7.

So I have a new mesh and cut the parts.

now when I try it I get a runtime error?

So I was able to get the new mesh working.

but some issues: Stuck in the surface

So for touchdown point code I have this:
Code:
TOUCHDOWNVTX td[4];

double x_target = -0.5;
double stiffness = (-1)*(MASS*9.80655) / (3 * x_target);
double damping = 0.9*(2 * sqrt(MASS*stiffness));
for (int i = 0; i<4; i++)
{

td[i].damping = damping;
td[i].mu = 3;
td[i].mu_lng = 3;
td[i].stiffness = stiffness;
}
td[0].pos.x = cos(30 * RAD)*ro;
td[0].pos.y = -Height_From_Ground;
td[0].pos.z = -sin(30 * RAD)*ro;
td[1].pos.x = 0;
td[1].pos.y = -Height_From_Ground;
td[1].pos.z = 1 * ro;
td[2].pos.x = -cos(30 * RAD)*ro;
td[2].pos.y = -Height_From_Ground;
td[2].pos.z = -sin(30 * RAD)*ro;
td[3].pos.x = 0;
td[3].pos.y = 15 * ro;
td[3].pos.z = 0;

SetTouchdownPoints(td, 4);

Code:
Height_From_Ground = 0;

The Emirates Mars Mission had just recently launched and it's on it's way to the Martian System, while Tianwen-1 is launching on Thursday and Perseverance is going to launch on July 30th.

Yes, launch opportunities / windows are still a thing :thumbup:
Nice to have several different missions to try mars (which is hard).

unfortunately there will be no Mars rover ExoMars. where you can watch the launch of the Mars 2020 live (Live Stream)?

...where you can watch the launch of the Mars 2020 live (Live Stream)?

You can watch it live on YouTube once the day of launch approaches.....

Alternatively, space.com also hosts livestreams of rocket launched from time to time

So I think MS2015 maybe the way to go. Not sure the guidance will work for 2nds rockets? Working on meshes,...

So first stage would then have a centaur with all the rover, cruise,...

Ms2015 guidance can control all MS stages, including the Centaur. It's all down to the guidance file.
You can also have the cruise stage as part of the MS2015 vessel if that helps.

So with Brian's help we have launch:

The trick is going to be getting the skycrane/rover to the surface
