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…

⟨Damien⟩ ⟪Mudkip909 | 𒀱 supporter⟫ well it kind of looks like that for now ⮪ I'm not sure what frame that's in but it looks like way too much velocity
<queqiao->
⟨Damien⟩ you should just about reach the l-point with barely any excess vertical velocity
<queqiao->
⟨Damien⟩ try MCEA or whatever it's called now
<queqiao->
⟨Damien⟩ the one that fixes the position of the moon
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ why the moon though
<queqiao->
⟨Damien⟩ oh, are you trying to go to earth-sun L2?
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ yeah
<queqiao->
⟨Damien⟩ ah, my mistake
<queqiao->
⟨Damien⟩ yeah in that case you want the one where the earth and the sun are fixed
<queqiao->
⟨Damien⟩ ECSA maybe? Can't remember, I've not played in a while
<queqiao->
⟨Damien⟩ then just plan an ejection burn so you head away from the sun on the far side of earth but try and keep the velocity low. It can sometimes be easier to angle slightly left or right of the sun-earth line to allow for you to swing back towards the line to be captured
<queqiao->
⟨Damien⟩ the lower your velocity when you hit the point, the easier it is for your trajectory to be bent by the L-point
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ currently im right at the point
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ but the eci view isnt... great
<queqiao->
⟨Damien⟩ if you plan a maneuver and play with it you'll work it out
<queqiao->
⟨Damien⟩ start from scratch imo
<queqiao->
⟨Damien⟩ you don't even have to do the actual flight from orbit, just use the flight plan window
<queqiao->
⟨Damien⟩ once you can get your trajectory to bend at the l-point play with the initial ejection burn (more/less thrust, vary the ejection angle) you'll see how it affects things
<queqiao->
⟨Damien⟩ that's it, perform that burn then plan another correction burn once you're in it and you'll see how little Dv you need to get a coupe of decent loops in
<queqiao->
⟨Damien⟩ * couple
<queqiao->
⟨Damien⟩ very small burns are key
<queqiao->
⟨Damien⟩ like deep throttled RCS small
<queqiao->
⟨Damien⟩ thrust limiter is your friend
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ nvm this maneuver was in th past
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ still works a bit ahead tho
UmbralRaptop has quit [Remote host closed the connection]
<queqiao->
⟨SpaceMarine⟩ Id like to figure out and have someone explain to me how launches from baikanour would work using principia to multiple celestial locations, moon, interplanetary, other orbits etc. i understand you will need K0S never used it before so would also need a walkthrough on that.
<queqiao->
⟨SpaceMarine⟩ because i am interested in doing a soviet game with like ur700
<queqiao->
⟨SpaceMarine⟩ ur900 etc
<queqiao->
⟨Soviet Onion⟩ ⟪SpaceMarine⟫ Id like to figure out and have someone […] ⮪ Baikonur's inclination meant Soviets mostly went for polar orbits, right ?
<queqiao->
⟨SpaceMarine⟩ thats what i understand, and i understand to do so you need to launch at the right time
<queqiao->
⟨SpaceMarine⟩ which you need k0s for
<queqiao->
⟨SpaceMarine⟩ and thats without principia involved
<queqiao->
⟨Soviet Onion⟩ You don't really need kOS if you know what you are doing though
<queqiao->
⟨Soviet Onion⟩ Like, it's not a necessity
<queqiao->
⟨Quadrupole⟩ ⟪Soviet Onion⟫ Baikonur's inclination meant Soviets […] ⮪ They went polar primarily for direct ascent aiui
<queqiao->
⟨Soviet Onion⟩ Right
<queqiao->
⟨SpaceMarine⟩ yes but if i am going to be playing an entire soviet game am gonna be doing a crap ton of launches
<queqiao->
⟨SpaceMarine⟩ so i want to have an easy to use solution
<queqiao->
⟨Quadrupole⟩ I am working on a web calculator for off-plane moon shot but I cannot garantee when I finish it
<queqiao->
⟨SpaceMarine⟩ well good to know thats in the works
<queqiao->
⟨SpaceMarine⟩ but yea i have always wanted to launch from baikanour but the issues with launching to the moon always stopped me
<queqiao->
⟨SpaceMarine⟩ principia or no
<queqiao->
⟨Quadrupole⟩ In the time being just use Butcher' kOS script
UmbralRaptop has joined #principia
<queqiao->
⟨SpaceMarine⟩ again never used kOS before so i dont know how that would function
<queqiao->
⟨Aster // he/they/she // NDSE⟩ Anyone have the link to download Principia Working Group manually?
<queqiao->
I dont use CKAN
<queqiao->
⟨Aster // he/they/she // NDSE⟩ +so I need the manual
<queqiao->
⟨Stonesmile⟩ The readme on GitHub, principia isn't on CKAN
<queqiao->
⟨Aster // he/she/xey // NDSE⟩ Ah nvm im a bit dumb
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ ah yes
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ what lagrange point should i go to today
<queqiao->
⟨von Kerman⟩ Lucy mission 😛
<queqiao->
⟨von Kerman⟩ +It's a pity there are no actual asteroids there, but we can pretend there are
<queqiao->
⟨von Kerman⟩ * they
<queqiao->
⟨Butcher⟩ ⟪Mudkip909 | 𒀱 supporter⟫ what lagrange point should i go to today ⮪ Sun - Jupiter L4.
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ i was thinking near earth tho
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ one of earths lagranges
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ or moon or somethign
<queqiao->
⟨Mudkip909 | 𒀱 supporter⟩ maybe i should try l1
<queqiao->
⟨theeo⟩ speaking of that, how exactly do you go to langrange points in principia? and is there any practical use in RP1 for them?
<queqiao->
⟨(ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ 🎵 _there's a hundred and four ways to use n-body physics ..._🎵
<queqiao->
⟨dragon36⟩ ⟪theeo⟫ speaking of that, how exactly do you go […] ⮪ For Earth-Sun L4 and L5, I like to put my satellite into an elliptical orbit so after one orbit later, the earth will be ahead or behind by 60 degrees. Use the KSO reference frame and perform a burn to capture into the L4 or L5 point
<queqiao->
⟨(ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells)⟩ comms relays, low energy transfers, whatever James Webb is doing, whatever ISEE-3 is doing
