Request Artemis landers

[barrygolden]

they seem to be just a little hot

Sounds like thrusts are good?

Yes, thrust looks good.
The final hover thrust (just before touchdown) was around 50%, which is a reasonable throttle level.

For information, the braking burn from Lunar orbit in this scneario starts with 40% fuel.
It is assumed, the other 60% are used by the Lander during its TLI burn, Lunar capture and orbit lowering maneuvers.

Touchdown was with 3480 kg (32%) fuel remaining.

 

[gattispilot]

Thanks. What about the texture? And Rcs

 

[francisdrake]

On the textures:
Currently bigger parts have a coarser texture than the smaller parts. You could adjust this to be more uniform by modifiying the size of the U-V maps. I think this would look more consistent, because the Kapton (gold) foil does not know if it is wrapped around a big or small part.

For the tanks consisting of a cyclindrical body and 2 dished heads, you could combine them into a group and apply the U-V mapping to the group only. This would avoid the texture-jump at the end of the cylinders.



On the RCS:
1. It seems ok.
2. What I do (but this is really only my personal preference), if the RCS looks ok: I reduce the RCS thrust stepwise, until it is just no more ok. That means, if using an autopilot (like prograde) the vessel just over-swings slighty, before it is captured in the correct attitude. This avoids RCS being too strict. I would do this with ~ 80% fuel.

 

[gattispilot]

Thanks. So make the body coarse? I might make a new texture for the tanks. I can reduce rsc by 90 %

 

[gattispilot]

Try this.
HGA is functional
I may need to adjust for the rock launch

 

[francisdrake]

Looks very good!

Textures on the main body look much better now.
Question: Are the same textures used for the small tanks also?
Reason for asking is, these tanks look more sleek (like plastic), while the big-body textures look nice and grainy.

Vessel touchdown points are a bit high now, see screenshot.
RCS still could have less power.

Is there a key command for the HGA?

Thanks. On the HGA it should always be moving. I can add a key to stow it. Basically the dish will be facing down. I haven't textured it yet.
On the tanks I made a .obj and a texture map. It is basically the same. I can try to redo them.
what scn are you using?

Attached is the zip-file with two additional scenarios:

• MK1landertest in Lunar orbit
• Mk1landertest at Ukert crater

In the zip-file is also a 'dummy' Moon base named "Ukert".
This provides a base (just a landing spot, no buildings) at the rim of the Ukert crater, near the Moon equator.
This file goes to the Config - Moon - Base folder.

Anyone working on these for Orbiter? The Dynetics lander looks really interesting.

Defo up for an Artemis moon lander

 

[gattispilot]

I wonder if I need to add those white struts on the body?

 

[gattispilot]

So we get this.
Thanks to @francisdrake for the tanks texture.
CTRL 3 stows HGA
G gear
I adjusted the landing points,...
But when I apply a slight hover and let her drop the landing points seem good. But she starts to slide.

I wonder about the big tanks. I have seen they with white foil and Blue Moon on them. And then there is this. where they are gold foil? And the struts are not covered?

 

[N_Molson]

I'd say it is a good idea to wrap the tanks into MLI. Once landed, you can't do things like PTC. Even if the tanks are mostly empty at that point.

 

[gattispilot]

So go with gold tanks?

 

[N_Molson]

Safe bet. Keep in mind that the lander will be torched by the Sun once its there. And the lunar days last 14 Earth days.

 

[gattispilot]

Here you go. Gold tanks

 

[N_Molson]

Looks good. I'd play a bit with the D3D9 Client 'in-sim' material settings for an optimal result. Metalness shader.

Set a high (not max) 'metalness' value, and play around with 'smoothness' (or 'roughness', same thing, start from mid-range). Even the white paint should have some metalness, 0.4 to 0.6 I'd say.

For the legs, the 'Eagle' LM ones were covered with MLI too. I guess they had their reasons. And don't forget the flag !

 

[gattispilot]

Flag? I used a foil/grey texture for the legs

 

[diogom]

It seems like almost everything is covered with the stuff, legs included, though with that more orange kind.

 

[gattispilot]

Yes. Looks like just the top is white. Maybe lower body orange foil, tanks and the rest yellow foil. Legs orange foil
