<queqiao-> ⟨clayel⟩ wouldnt it give different results vs patched conics?

<queqiao-> ⟨razgriz16⟩ ^Good news is that rebasing works now 😬
<queqiao-> ⟨danimalfarm⟩ I remember hearing that airlaunching was wonky with Principia, is that still the case?

<queqiao-> ⟨test_account9540⟩ that was several years ago
<queqiao-> ⟨sichelgaita⟩ Thanks for reporting. We'll do a hotfix, but due to personal circumstances this might take a little while.
<queqiao-> ⟨danimalfarm⟩ Good to know! The recent mention must have been erroneous.
<queqiao-> ⟨danimalfarm⟩ * erroneous (and based on outdated information)
<queqiao-> ⟨Damien⟩ Ksptot did add support for n-body coasts but grim what I recall it did have issues with the orbit tilting stuff Principia does so using may not be as simple as it would be without principia
<queqiao-> ⟨Damien⟩ * from
<queqiao-> ⟨Damien⟩ +it
<queqiao-> ⟨Damien⟩ * body/orbit
<queqiao-> ⟨_newhere⟩ On the upside you can finally rebase your flight plan - on the downside you can't delete flight plans(atleast not from the previous version) .
<queqiao-> TBH I'm kinda suprised that they waited for so long to name a version after the guy who came up with the Jordanian form, especially considering all the vector transformation they must do in their code...
<queqiao-> ⟨_newhere⟩ does anyone knows if the rest Principia's functionality works? I really need rebasing for a Jupiter capture/Io perijove lowering
<queqiao-> ⟨clayel⟩ it is on by default or
<queqiao-> ⟨rnlahaye⟩ The names are in alphabetical order
<queqiao-> ⟨Damien⟩ You select 'n-body coast' as an option in your flight plan. It's been a long time since I used it but if you have a look you'll find the option or read the documentation

<queqiao-> ⟨egg⟩ Though now there is the Leiden unified transliteration of Egyptian, and 𓇹𓄟𓋴𓏲 which we counted as jꜥḥ-ms.w would be ı͗ꜥḥ-mz.w I think

<queqiao-> ⟨_newhere⟩ Yeah, but we've gone through J multiple times already - you would think Jordan will higher on the list. Or is it lexicological order(ie finite predetermined list)?
<queqiao-> Also, is the issue of orbit analysis not working in flight planning known?
<queqiao-> ⟨egg⟩ Your flight plan is too short I think.
<queqiao-> ⟨egg⟩ Wait no, that seems fine.
<queqiao-> ⟨_newhere⟩ believe me I triple checked it - anyway, I don't get any window popping up when I click analyse final trajectory. It should pop the windows and tell me it cannot resolve the orbital elements...
<queqiao-> ⟨egg⟩ Yes, I reproduced it; something is rotten in the kingdom of Denmark. We need to figure out what is going on with that optimizer.
<queqiao-> ⟨issproxima⟩ How to make electric propulsion work with principia, there should be a way to execute those year long burns
<queqiao-> ⟨_newhere⟩ Run KSP in the cloud?
<queqiao-> ⟨issproxima⟩ In stock that's persistent thrust
<queqiao-> ⟨issproxima⟩ But that's not gonna work with principia
<queqiao-> ⟨clayel⟩ simple, you dont
<queqiao-> ⟨clayel⟩ although you should be able to get up to 10-15x timewarp with time control/better time warp
<queqiao-> ⟨clayel⟩ +physical
<queqiao-> ⟨makoivis⟩ Anyone else getting crashes when deleting flight plans?
<queqiao-> ⟨egg⟩ everyone is.
<queqiao-> ⟨makoivis⟩ gotcha. reverting for now
<queqiao-> ⟨clayel⟩ oh yea, it looks like you can choose the type of calculations you want in ksptot with the gravitational parameter
<queqiao-> > We are aware of multiple bugs with [the Jordan] release: deleting a flight plan results in a crash, and orbit analysis on the flight plan no longer works.
<queqiao-> >
<queqiao-> > We are trying to understand and resolve these issues. Once they are resolved, the release will be patched as others have been in the past (most recently 伊藤 six months ago).
<queqiao-> ⟨egg⟩ Our best engineers are working on this issue. Our worst engineers, too.
<raptop> egg: Do you cat(s) have PE licenses?
<queqiao-> ⟨egg⟩ I believe siimav would say something along the lines of :workbeale:
<queqiao-> ⟨redtyro⟩ so I updated before the bug was noticed (I'm almost at the point where I need to start using maneuver burns, but not quite there yet on my current career). It sounds like, for the time being, if I want to be able to rebase, do final trajectory analysis, and close/cancel flight plans, I should downgrade two versions... is that right?
