Great work. I like the on screen commands, it's a simple and effective interface.

Thanks. The Control Panel is a bit primitive, but its the best I can do - and better than trying to cram everything on the HUD.

Cheers,
Brian

The panel is OK and does it's job!

But I was talking about the HUD keys, those are great and really handy.
Feels like you are flight director and flowing the launch using an on-board camera.

Hi Brian,
During the weekend, I did many test-launches with the FH. I made a small 2K payload cfg file to represent the Roadster. I noticed that the total mass of the satellite is always 2000kg extra on top of the amount in the cfg file. So I put it to 0KG to end up with 2000KG. Can you explain why this is?

And regarding EDL ONLY landings: Am I right that I need to position the ASDS using the scenario editor to position it at the estimated location as indicated on the launch panel? I haven't been able to do succesful EDL ONLY landing, even when ending up quite close to the ASDS.

I noticed a few minor things which might require your attention:

-The shadows of the cores during landing are not visible when the pass over the landing pad and/or ASDS. They seem to go under.
-When looking back using the E key on the 2nd stage, exhaust flames are not visible. They are visible from the external view.

Ah, right! Yes, I figured there was still a use for HUD info and some shortcut commands.

At a guess, propellant mass of your payload. Falcon(9/Heavy) should add only the total mass of any attached payload.

Yes, but the estimated position is not entirely reliable - it's an approximate analytical function, to get a more accurate solution I think I'd need to do a numerical-step function to simulate the simulation before you launch! (another 6 months work probably).

EDL-Only flight profile is the the most difficult to get right, in terms of ASDS position and reentry/landing burn, for various reasons (high velocity, long range, shallow approach angle, restricted fuel reserve).

Having said that, I've launched a 2000kg sat on the FalconHeavy with the Centre booster set for EDL-Only to ASDS, Port/Starboard boosters Flyback-EDL to LZ's, -29deg inclination, 200km parking orbit, and it worked ok (although the MaxQ on the way down is quite nasty).

What were your launch parameters and ASDS pos?

Not much I can do about that, just the way Orbiter rendering works. Vessels don't shadow other vessels. Engine exhaust is visible from cockpit sometimes - sometimes not.

Cheers,
Brian

Hello everyone,
concerning the body of the Falcon9 CRS-13 on the images have distinguished well the traces of soot from the previous flight (CRS-11).
The landing legs are new so white, and the vertical white "features" are actually the cleaning of the welds for safety inspections.















EDIT:
And now : Falcon9 SES-16 GovSat-1

Hi Brian,
On my last flight all three cores landed using EDL ONLY. So the estimations are reliable it seems. I must have done something wrong the other time. Thanks for answering questions quickly.

Hello Brian

After the success of SpaceX to recover the caps of the FalconX,
it will be necessary that you update your Addon !!

Thanks again for your great work.

Yes. I think SpaceX are doing this just to keep me busy making Orbiter add-ons
A self-guided parafoil is quite an interesting problem, especially with wind effects.
Here's a .pdf about it....

I edited the 1st stage mesh to use the "charred" texture (I'll make it configurable from the .cfg file in future). Looks alright....

Think I found a bug with the Lift-off timer too (T-00:00:60 ??) Need to check that.

Cheers,

I was wondering about that timer. I didn't think it was a bug. There seems to be no second missing or counted twice.
It counts down like:
1:01
0:60
0:59

0:60 should be 1:00

SpaceX Fairing Recovery Vessel "MR STEVEN" is almost ready for deployment.
Just need some autonomously guided fairings for it to catch.

A couple more development screenies.....

Falcon9 fairings complete with RCS, Parafoils and basic guidance, on their way down...

Needs a bit more work on the parafoil final approach, and I'm way off estimating the FRV(Fairing Recovery Vessel) position but I might put a version up on OH soon :-)

Cheers,
Brian
