Awesomeness as always Brian, Thank You!

 

[Interceptor]

This is really cool ,thanks Brian!

 

[BrianJ]

Thanks for the kind words, hope it's fun. Looks like I ran out of time before Saturday, so I hope it all works OK.

It's nice to get into a straight-forward Mars transfer again!
Marco_A/B flyby for comms relay is an extra challenge.
AtlasV launch from West Coast is cool, looks like it flies almost parallel to the coast.
Nice views of the Centaur over the Himalayas just before final burn.
Am looking forward to Saturday
Cheers,
BrianJ

Thanks Brain!

From looking at the "Trajectory Design" video in this post, looks like they could be sticking to the 158deg launch azimuth constraint for Vandenberg, and doing a bit of a "dogleg" maneuvre during ascent. There is enough dV for it.

Attached .zip is revised guidance file for the AtlasV AV078, which is probably a bit closer to this. Starts out at 158deg azimuth, then corrects inclination after fairing separation.

 

[BrianJ]

OK, I should have paid more attention to Jim Green when he said the Atlas does a "big left turn" during the final burn.

I'm so used to trying to minimise off-plane components of the final transfer burn.

Yes, you need a hefty plane change in the final burn if you're at 64deg.inc., but the AtlasV has enough dV for that.

So, as far as I can see, AtlasV launches to ~158deg azimuth, core stage does a little bit of a dogleg to correct the inclination to 64deg.inc. Then there is the "big left turn" during the final burn.

Here's a revised guidance file that get's closer to that initial launch profile to parking orbit.

Hey Brian a super job again but my lander is below the surface when landed ?

 

[BrianJ]

Hi Barry,
I'm afraid that's just down to how Orbiter renders the Mars surface.
It might work better if you get the Mars hi-res surface pack, but thats ~20Gb total download, which is a hefty chunk of my HardDrive, so I never tried it.

If you deselect Orbiter "Surface Terrain" for the landing, it works better (and you get a little patch of hi-res surface spawned by the lander before touchdown.

Cheers,
Brian

 

[barrygolden]

where do I find that ?

Mars Hi-Res pack:

Remember to follow the installation instructions:

where do I deselect surface terrian ?

 

[jgrillo2002]

I saw that the MARCO cubesats are stowed next to each other. After the first is jettisoned, the boosters does a 180 deg. turn and then deploys the second one

On your Orbiter Launchpad window, select "Visual Effects" tab, untick the "Surface Elevation" box.

Yeah, hadn't seen that video when I made the Centaur, it's close enough though.

Cheers,
Brian

Thank you BrianJ for a great mod. The real InSight will land on Mars in 4.5 hours, and I planted it now))) Great job BrianJ.

 

[Yuri_Gagarin]

Get ready.
