⟨Pumpkinaxe⟩ Theoretically, if I downloaded
<queqiao-_>
⟨Pumpkinaxe⟩ Theoretically, if I downloaded Principia for the n-th time, would it be unreasonable to delete folders for other operating systems like linux or mac?

⟨Pumpkinaxe⟩ heh, i confused sedna with ceres and was a bit confused when reading that. Like, do you really need 20 years to get to ceres???

⟨!Kerbinator (UTC+8)!⟩ emm
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ looks kinda direct? (directly inject to a Jupiter transfer?)
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ because trying to further squeeze delta-v cost to 4000ish will require Venus/Earth assists
<raptop>
presumably
<queqiao-_>
⟨lucgamer⟩ Hey guys I'm new whit principia, I've downloaded it and moved the files to gamedata, but when I open the game it loads the expansions, (making history and breaking ground) but later that the game only closes, idk what to do
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ screenshot of modlist, and KSP.log please @lucgamer
<queqiao-_>
⟨lucgamer⟩ I can do that, but tomorrow, if I turn the PC on now my dad's gonna kill me
<raptop>
I have a few random guesses based off of the FAQ (C++ dll?)
<queqiao-_>
⟨Quadrupole⟩ Referring to the Sedna paper, I like it that they actually considered Oberth maneuver, which is basically
<raptop>
I mean, drop to the sun and do a big prograde burn at perihelion is an idea that's out there
<queqiao-_>
⟨Quadrupole⟩ Also duh, today I learned the way to go to sun-earth L4/5 is first burn into a Hilda orbit and then circularize at the Lagrange point. That was my first thought, but I thought that was inefficient
<raptop>
ooh, shiny

<queqiao-_>
⟨Jovietus Gravitas⟩ Is a Hilda orbit a transfer to Lagrange point?
<queqiao-_>
⟨Jovietus Gravitas⟩ Could you please post a screenshot of that?
<raptop>
Apparently it works as one. In the case of the Hilda group proper, it means a 3:2 resonance orbit (though not quite like neptune-pluto)
<queqiao-_>
⟨Jovietus Gravitas⟩ Either way, I try to head over to L1 or L2 around the sun, but I don't get that kidney bean shape. I only get a twist on my escape from earth.
<queqiao-_>
⟨Quadrupole⟩ I never did a sun-earth L1/2 mission, but I guess you can inject way off the point itself, a la JWST

⟨!Kerbinator (UTC+8)!⟩ not weird

⟨!Kerbinator (UTC+8)!⟩ \*logs
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ You'll find that it roughly having a pattern
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ You'll find it roughly having a pattern (edited)
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ (however I don't get it exactly how to inject into that type of orbit; halo and lyapunov gets easier to understand, though.
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ Such shape is easily obtainable by having an eclipse whose long axis has a certain angle to Z axis, and rotate the eclipse. Get a point on eclipse moving at a manner that on the plane of eclipse will easily create such a shape via printing a locus
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ Such shape is easily obtainable by having an eclipse whose long axis has a certain angle to Z axis, and rotate the ellipse. Get a point on eclipse moving at a manner that on the plane of eclipse will easily create such a shape via printing a locus (edited)
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ (right?)
<queqiao-_>
⟨Sumguy⟩ You missed one
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ btw what manoeurve should I burn to get me into such orbit
<queqiao-_>

<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ From Lyapunov to Halo I know
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ and from an escape orbit to Lyapunov is also relatively easy
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ and from an (almost) escape orbit to Lyapunov is also relatively easy (edited)
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ I'm opening KSP now (principia installed)
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ Now seems to be going Lissajous for 2 orbits now
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ (A complete Lissajous orbit requires simply too much time and can hardly be displayed fully)
<queqiao-_>
⟨Quadrupole⟩ It is likely that you F12'ed into a perfectly equitorial orbit and Principia divided by zero while finding the nodes.
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ No
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ Firstly this is in ECSA (ESO, or GSE) frame, and Ecliptic plane is 0 for AN/DN
<queqiao-_>
⟨!Kerbinator (UTC+8)!⟩ another thing is, I used set orbit command to put me into equitorial LEO, then use infinite fuel cheat to burn 4000m/s for burn to Ecliptic-aligned LEO

⟨egg⟩ @von Kerman are there standard abbreviations for delete/(add or insert? in french I was able to use suppr. and ins. but Удалить Добавить are a bit long (not the end of the world, I can make the buttons wider, but if there is a well-established short form that’s better)

<queqiao-_>
⟨von Kerman⟩ You could maybe abbreviate "Удалить" as "Удал." but it's not standard
<queqiao-_>
⟨von Kerman⟩ "Добавить" - "Добав." but again, I wouldn't call it standard
<queqiao-_>
⟨egg⟩ seems to be somewhat attested at least (cursory googling finds user manuals with Добав./удал.Избранные)
<queqiao-_>
⟨von Kerman⟩ it's more or less ok
<queqiao-_>
⟨von Kerman⟩ "окончательная" - could also be translated as "финальная", which is shorter
<queqiao-_>
⟨von Kerman⟩ so "окончательной" - "финальной"
<queqiao-_>
⟨von Kerman⟩ "эллиптическая" - "эллиптич." which is shorter and doesn't change
<queqiao-_>
⟨egg⟩ > финальная
<queqiao-_>
⟨egg⟩ that is starting to look like the sort of Russian they speak at the beginning of Война и Мир
<queqiao-_>
⟨von Kerman⟩ no, it's a common word
<queqiao-_>
⟨egg⟩ (I was just joking that it resembles the french word :-p)
<queqiao-_>
⟨von Kerman⟩ Yes, it's a loanword, but it's used very often

⟨Paculino (ŝi/ri/she/they)⟩ Does it normally do stuff like that?
<queqiao-_>
⟨egg⟩ it does some interesting things, but it certainly doesn’t shine by its documentation, so normality is hard to ascertain. But it does that, normal or not: <https://lingoona.com/cgi-bin/grammar#l=ru&t=%3C%3Cgen%3A%D0%BA%D1%80%D1%83%D0%B3%D0%BE%D0%B2%D0%BE%D0%B9+%D1%81%D0%B8%D0%BD%D1%85%D1%80%D0%BE%D0%BD%D0%BD%D1%8B%D0%B9+%D0%BE%D1%80%D0%B1%D0%B8%D1%82%D0%B0%5Ef%3E%3E&oh=1>

⟨DRVeyl⟩ Are you confusing it with case? (Ending ой is masculine or neuter, but орбита is feminine?)
<queqiao-_>
⟨DRVeyl⟩ Are you confusing it with case? (Adjective Ending ой is masculine or neuter, but орбита is feminine?) (edited)
<queqiao-_>
⟨DRVeyl⟩ Are you confusing it with gender? (Adjective Ending ой is masculine or neuter, but орбита is feminine?) (edited)
<queqiao-_>
⟨egg⟩ well, I’m trying to get it to handle case, but if I feed it nominative feminine adjective it’s even bloodier
<queqiao-_>
⟨DRVeyl⟩ Gen should be :круговой орбиты I think
<queqiao-_>
⟨egg⟩ yup, it is able to construct the genitive feminine correctly for that adjective
<queqiao-_>
⟨egg⟩ but only if I give it the nominative masculine
<queqiao-_>
⟨egg⟩ and also only if it is the first adjective, because if I flip them around I get синхронную круговойой орбиты
<queqiao-_>
⟨egg⟩ oy indeed
<queqiao-_>
⟨DRVeyl⟩ Or :круговой синхронной орбиты for gen singular
<queqiao-_>
⟨egg⟩ yeah
<queqiao-_>
⟨DRVeyl⟩ Yeah, I have no idea what longoona is doing ;)
<queqiao-_>
⟨egg⟩ the conclusion is probably that I can’t decline orbit descriptions, so nominative in parentheses it will be
<queqiao-_>
⟨egg⟩ to be fair lingoona is somewhat beyond the bleeding edge of technology in that realm, ICU doesn’t try anything as fancy
<queqiao-_>
⟨egg⟩ as a result, it is quite bloody indeed :-p
<queqiao-_>
⟨DRVeyl⟩ Or wait for von Kerman to get back, since my memory of declension is gotta be 20 years out of date.
<queqiao-_>
⟨egg⟩ well, looking up declension tables isn’t hard, but I don’t want to write bespoke code and strings to do grammar to the rather complex beast that is orbit description ; if lingoona can’t decline adjective, I won’t decline adjectives
<queqiao-_>
⟨egg⟩ well, looking up declension tables isn’t hard, but I don’t want to write bespoke code and strings to do grammar to the rather complex beast that is orbit description ; if lingoona can’t decline adjective sequences, I won’t decline adjective sequences (edited)
<queqiao-_>
⟨DRVeyl⟩ Ahh, I begin to understand now.
<queqiao-_>
⟨egg⟩ Principia has fancy orbit detection and analysis code that tells you that you are in, e.g., a highly eccentric equatorial geosynchronous orbit; that translates relatively well, but then the flight plan says that you coast *in* highly eccentric equatorial geosynchronous orbit, and there things become sad with case
<queqiao-_>
⟨von Kerman⟩ I can just confirm again that the text will be understandable without declension
<queqiao-_>
⟨egg⟩ yeah I will just make it Полёт в течёние [some time] (blah blah орбита вокруг Кербина), that way it’s not actually incorrect
