02:59 <stratochief> never had principia die on me before. seems to be an unrecoverable failure on a save?

02:59 <stratochief> principia reports "https://github.com/KSP-RO/RealismOverhaul/blob/master/GameData/RealismOverhaul/RealPlume_Configs/Squad/turboFanEngine.cfg"

02:59 <stratochief> ahh, rather (oh, remotedesktop copy-paste) Error extending trajectory for Vall. Error trying to fit a smooth polynomial to the trajectory. The approximation error jumped from +2.14521080651756159e-02 m to +5.57697703015024017e+04 m at time +3.16872000000000000e+07 s. The last position is {-6.96116200806107178e+10 m, +1.01087428725614910e+10 m, +1.38901548664691877e+09 m} and the last velocity is {-3.89294255342327278e+03 m s^-1, -

02:59 <stratochief> 2.87576456229720907e+03 m s^-1, +1.23059135521097467e+01 m s^-1}. An apocalypse occurred and two celestials probably collided because your solar system is unstable.

03:14 <rsparkyc> i had that

03:14 <rsparkyc> it turned out i didn't have the patch to update the jool system

03:15 <rsparkyc> let me find it for you

03:15 <rsparkyc> stratochief: https://github.com/mockingbirdnest/Principia/wiki/Installing,-reporting-bugs,-and-frequently-asked-questions#kopernicus-users

03:15 <rsparkyc> it's the link in that section

03:16 <rsparkyc> now i'm trying to figure out the low energy transfer to L4/L5

03:17 <rsparkyc> https://www.researchgate.net/publication/281717946_Optimal_low-cost_transfer_to_L4_and_L5_lagrangian_points_based_on_G-family_of_periodic_orbits

03:25 <stratochief> thanks! I'll check that patch.

03:25 <stratochief> hopefully that paper is sufficiently applicable to the Kerbin-Mun system

03:26 <rsparkyc> yeah, i don't fully understand it yet

03:27 <stratochief> ahh IIRC, those are some of the easier L points to visit. basically, just to a regular transfer like you're aiming for the moon, just do it a good chunk of an orbit too early or late :P

03:28 <stratochief> maybe not the lowest possible energy transfer, but straightforward

03:29 <rsparkyc> yeah, i'm trying to find a low energy version

03:30 <rsparkyc> i've gotten into them pretty easily already

03:52 <rsparkyc> more interesting stuff: https://www.youtube.com/watch?v=CjKPnpjk4Lg

04:43 <rsparkyc> Here's a challenge: starting at LKO (say 100km x 100km), what's the lowest total plan deltaV for you to enter a stable orbit around Kerbin Moon L4 or L5, and maintain it for at least 100 days

04:43 <rsparkyc> currently i'm at 1038 m/s

04:43 <rsparkyc> technically i have a starting orbit of 94 x 80

07:26 <egg|zzz|egg> stratochief: that's because we incorrectly detect stock

07:26 <egg|zzz|egg> stratochief: so we don't fix it, and stock is unstable

07:26 <egg|zzz|egg> stratochief: in Cartan we'll detect stock properly

07:32 <egg|zzz|egg> stratochief: see https://github.com/mockingbirdnest/Principia/pull/1311
