01:16 <queqiao--> <N​aa​ut​il​us​> you never know

03:21 <queqiao--> Reply to "e​gg​: Do you mean around the Moon? You could pick repeat ground track orbits"

03:21 <queqiao--> <Q​az​er​ow​l> honestly, everywhere. I don't know if orbital precession is mostly due to mass differences in the body you're orbiting or the influence from other bodies. I was hoping that easy hack would get me partway to a "principia with patched conics". But I'm guessing it wouldn't actually make that big a difference.

03:27 <raptop> ezsnack: belatedly, I'd have assumed that there's no good ballistic capture options for something with a periapsis in LEO. Though maybe there's something that passes through L1?

03:31 <raptop> Qazerwol: it depends on the body and orbit, really. Or, low lunar orbits care about masscons, GEO cares about lunar (and solar) perturbations, etc

03:37 <queqiao--> <e​zs​na​ck​> Afaik yea you can use l1

07:38 <queqiao--> <M​il​an​97​> Thanks sir.

07:38 <queqiao--> <M​il​an​97​> So there will be a popup warning for crashes?

07:38 <queqiao--> <M​il​an​97​> Also is it even possible to make principia work with binar systems? There are some quite unreal planet packs here.

07:38 <queqiao--> <M​il​an​97​> And how does ksp missions handle this? I am a career player, and there are a lot of flyby, and orbit missions, for which I must enter SOI. Or there are SOIs, but they are not visible?

07:38 <queqiao--> <Q​az​er​ow​l> Principia will "work" with any pack as long as the planets don't crash into each other once principia takes over their orbits. In the stock system, that happens with some of Jool's moons so principia has a patch that moves them a bit so it doesn't happen. It wouldn't be too hard to do that with other packs. Just start a new save with principia and start timewarping. If you make it to several hundred or a thousand years

07:38 <queqiao--> without a popup saying that planets crashed into each other, you're good. If they do crash, you'll need to figure out how to spread them out (or something more complicated) to avoid that, and then re-test with a new save.

07:54 <queqiao--> <s​ic​he​lg​ai​ta​> There will be a pop-up talking about an apocalypse if two celestials collide. There is nothing special about binary systems, so if a binary system is stable in real life, it will be stable in Principia. I'm not sure if anyone bothered to define a configuration for a binary system, though. As you say, there are wild planet packs out there, and Principia won't be compatible with nonphysical objects (e.g.,

07:54 <queqiao--> wormholes) or systems substantially larger than the real solar system. (I know that Kcalbeloh has a dedicated configuration to address these pitfalls.)

09:12 <queqiao--> <M​il​an​97​> Ok, then I will give it a shot. How about the missions related to SOI changes?

10:57 <queqiao--> <D​am​ie​n> They still work at the usual ranges

11:20 <queqiao--> Reply to "D​am​ie​n: That's what they want you to think"

11:20 <queqiao--> <B​ut​ch​er​> Komrade Boris agrees.

17:11 <queqiao--> Reply to "Q​az​er​ow​l: honestly, everywhere. I don't know if orbital precession is mostly due to mass difference..."

17:11 <queqiao--> <e​gg​> Precession is not normally something you want to correct for by stationkeeping, instead you should see it as part of your orbit.

17:12 <queqiao--> <e​gg​> Use the orbit analyser to understand what your orbit is doing long-term.

17:43 <queqiao--> <m​ak​o> there are orbits that counteract the precession to remain in a particular plane

17:43 <queqiao--> <m​ak​o> molniya, various geosync orbits

17:44 <queqiao--> <m​ak​o> and then SSOs use the precession to keep a constant orientation with respect to the sun
