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-> ⟨Kerbinator⟩ why it wobbles crazily for no reason? (the new rotation algorithm seem to be better though, when coping with reentry in stock aero)
<queqiao-> ⟨Kerbinator⟩ but here I'm in vacuum above Triton
<queqiao-> ⟨Kerbinator⟩ and there is no way to save the poor kerbal because once the bug rotation start
<queqiao-> hyperedit land, set orbit (stock or hyperedit), time warp (in stock it will stop your rotation) is all useless
<queqiao-> ⟨Kerbinator⟩ * are
<queqiao-> ⟨Kerbinator⟩ (vessel is stock)
<queqiao-> ⟨Kerbinator⟩ spring and damper tweaked to maximum
<queqiao-> ⟨Kerbinator⟩ Oh, it partially occur in stock
<queqiao-> ⟨Kerbinator⟩ maybe just because angular inertia too low making even the small SAS too strong

<queqiao-> ⟨Kerbinator⟩ I finally got it
<queqiao-> ⟨Kerbinator⟩ probably because I was testing instability of the temporary Skylon FAR fix by JadeOfMaar sent to me, but the left wing has far less lift than right wing
<queqiao-> ⟨Kerbinator⟩ I finally got it, probably because I was testing instability of the temporary Skylon FAR fix by JadeOfMaar sent to me, but the left wing has far less lift than right wing that give the vessel a huge torque. I wanted to monitor lift of left and right wing when it was forced to flight horizontally and nominal
<queqiao-> ⟨Kerbinator⟩ so I edited the value of small SAS, in Squad folder config, to be an insane 500 😂
<queqiao-> ⟨Kerbinator⟩ +which immediately break up the rotation mechanic
<queqiao-> ⟨Kerbinator⟩ +solved even with the principia save that it rotates madly.

<queqiao-> ⟨TheSquirrelPatrol⟩ So now for the real fun: it's time for me to think about putting a communications relay at EML2. And I really have no clue where to begin. I assume I need to get inclination just right so when I'm 61,347km past the moon, I'm also perfectly on the Earth-Moon plane. What about velocity? The one video I saw of a Kerbin-Mun L2 flight, it didn't look like he was planning any kind of capture burn at the actual L2 point. Is it...
<queqiao-> ... easier to just do this as a burn from Earth, or capture at the moon and then raise aposelene?
<queqiao-> ⟨Stonesmile⟩ What I did when I launched EML2 relays; Normal TLI, small retro-fire at periselene that is not enough to capture into lunar orbit, then insertion into the L2 orbit some time after
<queqiao-> ⟨Stonesmile⟩ This shows it decently in the stock system https://youtu.be/LJbBPfXcNJg?t=544
<queqiao-> ⟨Stonesmile⟩ Keep in mind that a EML2 relay needs station keeping about once every 28 days
<queqiao-> ⟨TheSquirrelPatrol⟩ Of course that's the vastly simpler version with everything in the same plane. I don't think I've yet managed a perfectly coplanar TLI yet, though I haven't needed one. Should I be paying the pain at launch to get down to the right inclination, do an AN/DN burn on the way to the moon to get on plane, or perhaps just barely capture at the moon and then correct at the hopefully high AN/DN? Or just pay the extra dV to...
<queqiao-> ... correct at periselene if it won't be that expensive?
<queqiao-> ⟨TheSquirrelPatrol⟩ Assuming my periselene is at an AN/DN, which would take some planning just to ensure that..
