01:15 <raptop> wait, that implies that someone did fancy numerics in the 1880s

01:20 <queqiao-> ⟨(​ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ [New87] is a bit earlier than the 1880s

01:22 <queqiao-> ⟨C​zechoslovakia2⟩ Just a little bit earlier

01:25 <queqiao-> ⟨(​ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ to be fair, there are a lot more 1800s publications than more obscure 1600s publications

01:25 <queqiao-> ⟨(​ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ (on the other hand, the title of the mod should have obviated the answer significantly)

01:27 <raptop> Oh, *that* New

01:28 <raptop> ...does this mean that Principia impliments fluxions?

05:09 <queqiao-> ⟨J​ustMozzie⟩ whats the best way to plan interplanetary missions

05:36 <queqiao-> ⟨B​utcher⟩ :magic:

05:50 <queqiao-> ⟨B​utcher⟩ @egg Are you aware that there's a big stutter whenever something lands or takes off as the principia state tracking changes?

07:01 <queqiao-> ⟨A​shnoom⟩ I think it is the same behaviour as when enabling 'hack gravity' (landing/splashing down).

07:01 <queqiao-> ⟨A​shnoom⟩ Very noticible when the vessel keeps bouncing in the water and changing state between splashed and flying

07:16 <queqiao-> ⟨B​utcher⟩ Yes I had a craft that was dancing on the terrain (thanks Physx), it was stuttering like crazy, enabling hack gravity made it smooth.

07:26 <queqiao-> ⟨Z​eusbeer⟩ If you land a plane too fast in the water it will make funny spins and it keeps gaining :magic: energy

07:50 <raptop> like the infinigliders of old?

08:10 <queqiao-> ⟨Z​eusbeer⟩ Are those tossed around by a kraken till they explode?

08:18 <queqiao-> ⟨q​p⟩ Hey folks, I feel confident enough with rss-ro-rp1 that I am looking to get principia into the mix for my new playthrough. I am reading the wiki etc and want to ask if my understanding is correct. When I get principia installed, I won't be able to use mechjeb to plan and execute maneuvers and such - correct? Does that also mean I won't be able to use mechjeb pvg for getting to orbit ? Thanks

08:18 <queqiao-> ⟨(​ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ use PVG to orbit

08:18 <queqiao-> ⟨S​tonesmile⟩ PVG still works perfectly for getting into orbit

08:18 <queqiao-> ⟨(​ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ principia doesn't affect that

08:20 <queqiao-> ⟨(​ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ what you may be asking for here is using Mechjeb's Maneuver Planner, which IIRC is not compatible with Principia manœuvres

08:21 <queqiao-> ⟨(​ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ execute all manœuvres in Principia manually

08:21 <queqiao-> ⟨q​p⟩ Awesome pvg is what I was afraid of missing:) looking forward to play with principia! Thank you

08:22 <queqiao-> ⟨(​ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ have fun with 🟪🍜

08:22 <queqiao-> ⟨(​ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ enjoy the 🟪🍜 (edited)

08:54 <queqiao-> ⟨Q​uadrupole⟩ What are the characteristics of lunar gateway's near-rectlinear halo orbit?

08:55 <queqiao-> ⟨Q​uadrupole⟩ I assume it is a earth-synchronous frozen orbit that always face the earth

08:55 <queqiao-> ⟨Q​uadrupole⟩ with the eccentricity vector always pointing north

08:58 <queqiao-> ⟨S​tonesmile⟩ This video explains it quite well https://www.youtube.com/watch?v=X5O77OV9_ek

09:24 <raptop> ...does it have to be a video?

09:26 <queqiao-> ⟨s​ichelgaita⟩ Maybe open an issue with a short video? Egg doesn't play so is unlikely to be aware.

09:28 <queqiao-> ⟨e​gg⟩ that sounds like https://forum.kerbalspaceprogram.com/index.php?/topic/162200-wip181-191-1101-and-1110%E2%80%932-principia%E2%80%94version-gr%C3%B6bner-released-2021-06-10%E2%80%94n-body-and-extended-body-gravitation/page/70/&tab=comments#comment-3960511 but it was fixed in Green

09:28 <queqiao-> ⟨e​gg⟩ is it recent? did it come back?

09:28 <raptop> No, this was a generic youtube complaint, I wasn't expecting it to be only 2 minutes

09:29 <queqiao-> ⟨e​gg⟩ raptop: no I was replying to Butcher

09:29 <raptop> and focus heavily on being orbit visualization

09:29 <raptop> ah

09:29 <queqiao-> ⟨B​utcher⟩ It was present this morning, I am on Gröbner

09:30 <queqiao-> ⟨e​gg⟩ welp, I guess we added something else that takes a while to clean up

09:30 <queqiao-> ⟨e​gg⟩ please open an issue

10:55 <queqiao-> ⟨Z​eusbeer⟩ Wait so is near rectilinear halo orbit different than just an L1/L2 halo orbit?

10:55 <queqiao-> ⟨D​amien⟩ yes

10:55 <queqiao-> ⟨Z​eusbeer⟩ It has a period of 7 days

10:56 <queqiao-> ⟨Z​eusbeer⟩ That's kinda cool

10:57 <queqiao-> ⟨Z​eusbeer⟩ Its polar too

10:57 <queqiao-> ⟨Z​eusbeer⟩ 🤯

11:02 <queqiao-> ⟨D​amien⟩ I tried planning one out in principia but it was very fiddly

11:02 <queqiao-> ⟨D​amien⟩ https://cdn.discordapp.com/attachments/480397772248580098/707687382589243522/unknown.png

12:24 <queqiao-> ⟨e​gg⟩ @Butcher I can reproduce your issue (which you should open, though)

16:05 <queqiao-> ⟨Z​eusbeer⟩ It's supposed to be stationkeeped every 7 days at apolune

16:05 <queqiao-> ⟨Z​eusbeer⟩ so the fiddly part should make sense

16:10 <queqiao-> ⟨S​umguy⟩ For the moon, 27°, 50°, 76°, and 86° orbits are mostly stable.

16:11 <queqiao-> ⟨D​amien⟩ the NRHO precesses around the moon I believe

16:11 <queqiao-> ⟨D​amien⟩ I'm not sure if the inclination changes

16:15 <queqiao-> ⟨S​tonesmile⟩ Inclination stays the same, LAN changes by 360°/lunar revolution

16:17 <UmbralRaptop> ^

16:17 <UmbralRaptop> Something something earth-synchronous

16:19 <queqiao-> ⟨S​tonesmile⟩ Indeed, NRHO is never behind the moon, seen from Earth
