DaveyJ576 Posted October 7, 2021 Share Posted October 7, 2021 So curiosity got the better of me, and I downloaded the revamp branch to my Stock 1.11.2 game. FWIW, I also ran into an issue with the detachable version of the SLA fairings. Once on orbit with the S-IVB/LM/CSM stack I initiated the T&D maneuver. As soon as I hit the decouple button all four panels exploded outward, but one of them dragged the CSM around hard to the left and it very nearly collided with the LM, still stowed in the S-IVB. It was like a mini Kraken attack. I reloaded from a save twice more but got the same result each time. On the next mission I tried the hinged SLA and it worked perfectly. No LM on that mission. I dialed back on the detach force to 40% and perhaps that accounts for it. On the first mission the detach force was at 100%. I will try again with the first scenario to see if it repeats.

Expand No on the interstage. They removed them on Apollo 15 Onwards PS: @CobaltWolf updated the SLA panels. They're different from V1 SLA where they didn't have any engines to fire to push them a way and they went apart naturally. BUT honestly, I like it. Gives it a more Kerbal flare to it.

OrbitalManeuvers Posted October 8, 2021 Share Posted October 8, 2021 This was too cool not to share. Topic: Venus flyby mission. In spoiler tag for the uninterested. Reveal hidden contents This first image is from the NASA mission plan. I have marked 3 significant positions - Venus (orange) and Earth (blue) at launch, and Venus at flyby (green). This is my KSP tracking station, colored stars overlaid in the same position: Here's the KSP screen at 65% opacity over the NASA document: Kind of shocking that it's possible to get this close, tbh. The NASA flight plan calls for LEO, then transposition and docking, then the ejection burn. I'm using KSRSS at 2.5x. I launched from Kourou and tried to time my launch so that my equatorial DN would be positioned at/near the ejection burn point. PVG to 130km circular orbit on only the first two stages. I completed the transposition and docking and the rest of the prep for cruise phase within the first revolution so the ejection burn was done at the start of the 2nd revolution. Default boiloff settings. Took this crappy screencap immediately after completing the burn. Check out my fuel margins. I have an encounter, so I only used 1 ignition and then converted to the lab and extended the solar panels, and now everyone is taking a nap.

That means making extended versions of it gets weird kinda quick? I know that I'd like to make one that's vertical, so for landers and such you only need to worry about the cylindrical envelop and can ignore the slope. Past that, there's the large SAF fairings.
