08:16 <queqiao-> ⟨the rocket science kid⟩ ⟪paculino⟫ If you want a huge pointless challenge, […] ⮪ what actually happens during the a-bop-calypse?

08:16 <queqiao-> ⟨the rocket science kid⟩ ~bad pun~

08:17 <queqiao-> ⟨the rocket science kid⟩ * ~pun intended~

08:35 <queqiao-> ⟨test_account⟩ apocalypse message appears and the game can't be played anymore

14:37 <queqiao-> ⟨natjam⟩ Anyone done an LRHO before? I'm trying to put a station there but I can't get it to be stable

14:38 <queqiao-> ⟨natjam⟩ * NRHO

14:43 <raptop> It's not stable, though? I want to say that there are documents on stationkeeping requirements

14:45 <raptop> Hrm, https://ntrs.nasa.gov/citations/20190030294 does not make the exact amount of instability clear

14:45 <queqiao-> ⟨Soviet Onion⟩ yes, NRHO is not stable

14:45 <queqiao-> ⟨Soviet Onion⟩ but the stationkeeping costs much less than other unstable orbtis

14:45 <queqiao-> ⟨Soviet Onion⟩ * orbits

14:48 <queqiao-> ⟨SkyPhoenix999⟩ I keep trying to test NRHO by cheating something there but principia keeps blocking the cheat menu and hyperedit after the first use, I have to revert the flight to the launch pad to change the parameters in the cheat menu and set the orbit

14:49 <queqiao-> ⟨lpg⟩ Hack Gravity

14:49 <queqiao-> ⟨lpg⟩ (also in the cheat menu)

14:49 <paculino> I think there is a chart of typical stationkeeping on Wikipedia somewhere?

14:50 <queqiao-> ⟨SkyPhoenix999⟩ ⟪lpg⟫ Hack Gravity ⮪ Like set it to 0?

14:50 <raptop> there has to be in *some* trade study in NTRS

14:50 <queqiao-> ⟨lpg⟩ no. just enable it

14:50 <queqiao-> ⟨SkyPhoenix999⟩ Ah ok

15:27 <queqiao-> ⟨natjam⟩ Dang so I would have to do some manual burn every 7 days... that doesn't sound worth it to me in ksp

15:28 <queqiao-> ⟨natjam⟩ Especially when I start doing missions to Jupiter and stuff

15:45 <queqiao-> ⟨natjam⟩ Is there such thing as a highly elliptical polar orbit that IS stable?

15:54 <raptop> Molinya? (though I'm unsure on the exact stability)

16:18 <paculino> Is it a polar elliptical lunar orbit you want, or just any polar elliptical orbit, natjam?

16:19 <queqiao-> ⟨natjam⟩ Is there like a table of frozen orbits somewhere? I see that 86 degrees is somewhat stable according to Wikipedia but it doesn't give any other parameters

16:20 <paculino> You might try searching on Google scholar for papers on the subject; they typically have detailed tables. I would, but I'm using data now (irc to discord uses as much as sms)

16:24 <queqiao-> ⟨rnlahaye⟩ Isn't there a pinned message for this?

16:45 <queqiao-> ⟨egg⟩ ⟪rnlahaye⟫ Isn't there a pinned message for this? ⮪ There is, https://discord.com/channels/319857228905447436/480397772248580098/728371462964248617; surprisingly there isn’t a bibliography entry for it (there is [RL06] which is somewhat related, but does not have these nice graphs)

18:36 <queqiao-> ⟨natjam⟩ So anywhere along those lines is stable? and "a" is apolune?

18:37 <queqiao-> ⟨test_account⟩ This is truly a cryptic graph, no one is able to understand it when they first see it (myself included of course)

18:37 <queqiao-> ⟨test_account⟩ a is semimajor axis

18:45 <queqiao-> ⟨natjam⟩ are there more graphs like this? I was hoping to have a much higher apolune, like a = 5Mm or something

19:09 <raptop> I was going to complain, but apparently L1&L2 are at like 61 Mm

19:10 <queqiao-> ⟨natjam⟩ I'm trying to have some of the utility of an NRHO orbit but stable. So I was thinking high eccentricity
