egg changed the topic of #principia to: Logs: https://esper.irclog.whitequark.org/principia | <scott_manley> anyone that doubts the wisdom of retrograde bop needs to get the hell out | https://xkcd.com/323/ | <egg> calculating the influence of lamont on Pluto is a bit silly…
<queqiao-> ⟨DashFlashWayne⟩ @everyone https://discord.gg/pizza-town join now
<queqiao-> ⟨sichelgaita⟩ ⟪egg⟫ I’m not sure how you can get that error ⮪ We return this error when the adaptive step size integrator does not reach the final time due to a collision with a celestial. We should add a branch for this status in the C#.
<queqiao-> ⟨Overloader⟩ with principia is launching into the moons orbital plane still the best thing to do when tryiing to go to the moon? For me it worked out, just wondering if theres an even better way
<queqiao-> ⟨egg⟩ If you can do it it works, though most of the time you can’t do it from Florida.
<queqiao-> ⟨Overloader⟩ Well I'm on... I think it's called omolek?
<queqiao-> ⟨Overloader⟩ but if I was at the cape, how would I do it?
<queqiao-> ⟨egg⟩ Yeah Omelek should be a nice place from that standpoint.
<queqiao-> At the cape, there is a pinned diagram by Al2Me6 and a script by Butcher.
<queqiao-> ⟨Overloader⟩ Ah, transfer at ascending node, got it. The one thing that poped in my mind was to transfer from a polar earth orbit
<queqiao-> ⟨Overloader⟩ gotta say, maneuvers with principia feel much more satisfying
<queqiao-> ⟨Butcher⟩ Polar works but it's more expensive than just launching at the node.

<queqiao-> ⟨Overloader⟩ welp, in a simulation I did a pretty good mars flyby but now outside of simulation I cant get the mars periapsis low enough and I dont know what im doing differently
<queqiao-> ⟨Overloader⟩ Finally
<queqiao-> ⟨Overloader⟩ Dont know if thats what im supposed to do but It kinda got easier when I looked at the trajectory through the mars-sun plotting frame but made the maneuver with earth inertial
<queqiao-> ⟨egg⟩ yes, that is the normal way to do things
<queqiao-> ⟨Overloader⟩ Ah alright, thought I was supposed to do the maneuver with mars-sun as well
<queqiao-> ⟨egg⟩ no, your parking orbit makes no sense in MSO, so a burn from there based on the MSO line would probably end up being in a random direction.
<queqiao-> ⟨Overloader⟩ Well, in the simulation I somehow managed to do a flyby that way 😅

<queqiao-> ⟨egg⟩ It’s always possible to express anything in any frame, just harder :-)
<queqiao-> ⟨Kerbinator⟩ but if you can't see keypoints then it's not just harder, it's getting too hard.
<queqiao-> ⟨Kerbinator⟩ for example, the high efficiency of stock gravity assist planning is because you can see the AN/DN to a planet's orbital plane in HCI
<queqiao-> you may say that it can be replaced with xSO which will show you the node, but in xSO frame you lose the sun-center angle to other planets, which you can't see directly in xSO
<queqiao-> ⟨Kerbinator⟩ * planets (phase angle to be clear here),
<queqiao-> ⟨Kerbinator⟩ also, a thing: if you can show the periapsis and apoapsis of both object in xyO frame, it shall make things easier.
<queqiao-> ⟨Kerbinator⟩ +by deleting xyB frame you can replace it with yxO frame, which is usually used to determine phase angle easier.
<queqiao-> ⟨Kerbinator⟩ ⟪Overloader⟫ Dont know if thats what im supposed to […] ⮪ this is normal, however, regardless of what I said above (in general)
<queqiao-> ⟨Kerbinator⟩ these frame is for checking the plot, not for planning your maneuvers
<queqiao-> ⟨Kerbinator⟩ * frames are
<queqiao-> ⟨Zeusbeer⟩ ⟪egg⟫ Yeah Omelek should be a nice place from […] ⮪ There is now also a script by me
<queqiao-> ⟨Zeusbeer⟩ It timewarps you till you can launch directly east into the correct lan
<queqiao-> ⟨Zeusbeer⟩ I will share it later when I get home
<queqiao-> ⟨Zeusbeer⟩ The idea is simular to Ryans script but more brute forced
<queqiao-> ⟨Quadrupole⟩ ⟪badgermasher⟫ So long as the exemplar exhibits the […] ⮪ I did not expect the term "spin-orbit coupling" to be used on macroscopic objects...
<raptop> Quadrupole: so, uh, there are a lot of papers about exoplanets and spin-orbit alignment (or misalignment because that's more interesting)
<queqiao-> ⟨Soviet Onion⟩ ⟪Quadrupole⟫ I did not expect the term "spin-orbit […] ⮪ wat ? 👁️ :ey/
<queqiao-> ⟨Soviet Onion⟩ * 👁️👄👁️
<queqiao-> ⟨Quadrupole⟩ Yeah, it's just that I usually see that term being used to describe electrons
<queqiao-> ⟨Soviet Onion⟩ same
<queqiao-> ⟨Soviet Onion⟩ fine structure 😩
<queqiao-> ⟨Quadrupole⟩ Reminds me of how (Sommerfeld iirc) tried to explain fine structure as electrons taking elliptical orbits
<queqiao-> ⟨badgermasher⟩ Yeah, the few stellar examples where the Applegate mechanism might be having an observable effect on the stars are interesting.
<queqiao-> ⟨badgermasher⟩ * examples of stellar systems where the Applegate mechanism might be having an observable effect on the component
<queqiao-> ⟨badgermasher⟩ You will probably appreciate this abstract https://ui.adsabs.harvard.edu/abs/2020MNRAS.491.1820L/abstract
<queqiao-> ⟨Zeusbeer⟩ I will share it later when I get home ⮪ anyway as promised
<queqiao-> ⟨Zeusbeer⟩ It works nicely allthough I am not sure if it breaks really late game with Principia as I have no idea what reference POSITIONAT uses.
<queqiao-> ⟨Zeusbeer⟩ +kos'
<queqiao-> ⟨expanders are superior⟩ does principa show ascending node?
<queqiao-> ⟨Stonesmile⟩ Yes
