<queqiao-> ⟨Q​uadrupole⟩ Did you download principia from github master branch?
<raptop> As long as we're throwing darts, what about principia's other dependencies?
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Reinstall the initial dates file
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Reinstall the initial dates file maybe (edited)

<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ I just ran into the wiggly noodle issue as well (https://discord.com/channels/319857228905447436/480397772248580098/872210657284591616), but in a sim; adjusting tolerance/steps did not help, but it seems to have mostly applied in the further future, after a few more fly-bys
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ I will add more details when/if it persists outside of the sim
<queqiao-> ⟨S​ir Mortimer⟩ Pluto
<queqiao-> ⟨S​ir Mortimer⟩ Found in ... another discord server 🙂
<queqiao-> ⟨S​ir Mortimer⟩ I guess that would be a mission for when I'm retired: build a permanent base on pluto. With RSS.
<queqiao-> ⟨p​Edro⟩ What happens when a Kerbal retires while in transit ?
<queqiao-> ⟨p​Edro⟩ Will he get a "promotion" to Tourist ? will he just get up and walz out the airlock in search of a retirement home ?

<queqiao-> ⟨p​Edro⟩ All important questions for year long transits to all the way out there
<queqiao-> ⟨B​utcher⟩ I think they can only retire when at home.

<queqiao-> ⟨e​gg⟩ which reference frame is that?
<queqiao-> ⟨e​gg⟩ it is centred on Pluto, but the horizontal is clearly not its equator (which is the plane of its orbit around Charon)
<queqiao-> ⟨e​gg⟩ the orbital frame around the sun maybe?
<queqiao-> ⟨e​gg⟩ but that seems to be spinning way too fast for that
<queqiao-> ⟨e​gg⟩ @DRVeyl another (more typical, rotating solar panels and fixed instruments) attitude control law https://link.springer.com/article/10.1007/s00190-020-01342-2/figures/1

<queqiao-> ⟨e​gg⟩ again the only thing that matters is that the wings stick out of the box on a different side than the instruments, no magic angles
<queqiao-> ⟨e​gg⟩ (yes, box-with-wings is a term of art in discussions of SRP)

<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ I was checking to see if the apogee would continue to "drift" towards the equator indefinitely, and now see that it stops
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ What mechanism causes this to stop?
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ I was checking to see if the apogee would continue to "drift" towards the equator indefinitely, and now see that it stops

<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ What causes this to stop? Oblateness? (edited)
<queqiao-> ⟨D​amien⟩ when looking down at the earth from the pole, it has a minor and major axis. satellites will oscillate back and forth. the stable points are on the minor axis
<queqiao-> ⟨A​l2Me6⟩ Satellite is not in GEO...
<queqiao-> ⟨D​amien⟩ ah, I assumed it was
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ It is on its way to sun synchronous orbit
<queqiao-> ⟨D​amien⟩ probably oblateness or something else then
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Why would it stop and reverse halfway to the arctic circle though?

<queqiao-> ⟨e​gg⟩ that’s a thing, too, though I would need to dig up some references
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ If of help, it also kept lowering the eccentricity
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Is it merely "trying to reach" one of the stable points for the perigee and eccentricity?
<queqiao-> ⟨e​gg⟩ not sure ascribing agency to your orbit is going to help
<queqiao-> ⟨e​gg⟩ See http://dx.doi.org/10.1155/2013/191384, figures 6 and 7
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Thank you
<queqiao-> ⟨e​gg⟩ (yes, it’s Lara again)
<queqiao-> ⟨e​gg⟩ (in fact see all figures with an (e cos ω, e sin ω) diagram)
<queqiao-> ⟨e​gg⟩ see also AAS 13-867, THE ECCENTRIC BEHAVIOR OF NEARLY FROZEN ORBITS
<queqiao-> ⟨e​gg⟩ see also AAS 13-867, The eccentric behavior of nearly frozen orbits (edited)
<queqiao-> ⟨e​gg⟩ (though that is more about mean vs. osculating elements)
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ So I just happened to get close to a frozen orbit?
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ So I just happened to get close to a frozen orbit?
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ Yeah, figure 7 of AAS 13-867 is basically what I had (edited)
<queqiao-> ⟨e​gg⟩ yeah you will end up tracing some sort of blob in the (e cos ω, e sin ω) plane, ordinarily this blob will contain the origin and so the average rate at which you go around it is the apsidal precession, in orbits that vaguely lean towards frozen the entire blob can be off to one side
<queqiao-> ⟨e​gg⟩ (and in a frozen orbit the blob is small)
<queqiao-> ⟨e​gg⟩ See figure 2 of http://dx.doi.org/10.1155/2013/191384
<queqiao-> ⟨P​aculino (ŝi/ri/she/they)⟩ I did not think those would be applicable because the inclination is about 33 degrees off
<queqiao-> ⟨e​gg⟩ just because you are not near the critical inclination doesn’t mean that the same qualitative description doesn’t apply
<queqiao-> ⟨e​gg⟩ (of course the specific graphs will differ)
