<queqiao-> ⟨SpaceMarine⟩ So i am back here once more on the trip that is principia, this time I decided to do something stupid and play from new zealand, now I am wondering how the hell do i plan to get to the moon
<queqiao-> ⟨SpaceMarine⟩ any advice would be appreciated
<queqiao-> ⟨Stonesmile⟩ kOS; either using Butcher's script, or ItsRyan's. lmk if you want any links
<queqiao-> ⟨SpaceMarine⟩ I have 0 knowledge on how to use kOS so
<queqiao-> ⟨SpaceMarine⟩ any help or links
<queqiao-> ⟨SpaceMarine⟩ are appreciated
<queqiao-> ⟨Stonesmile⟩ This has some general info about how kOS works https://ksp-kos.github.io/KOS/tutorials/quickstart.html
<queqiao-> ⟨Stonesmile⟩ I would recommend itsRyan's script; it warps to the correct time for a launch directly east, no matter the location on Earth, and stages once at the correct time, starting PVG https://github.com/ryanc55/KOS-Scripts/blob/master/moonlaunchwindow.ks
<queqiao-> ⟨SpaceMarine⟩ so it works with pvg?
<queqiao-> ⟨Stonesmile⟩ Yep, the script does all of its work before launch and hands over to PVG at launch
<queqiao-> ⟨SpaceMarine⟩ nice alright guess i gotta read up then
<queqiao-> ⟨Stonesmile⟩ Feel free to ask any questions about how to use kOS over in #script-automation
<queqiao-> ⟨SpaceMarine⟩ alrighty

<queqiao-> ⟨SpaceMarine⟩ Stonesmile Well ig ot the program to run but now principia doesnt want to hit the moon
<queqiao-> ⟨Stonesmile⟩ The script should put you in an orbit where it's just prograde to hit the moon, are you in the right reference frame for the manoeuvre planner?
<queqiao-> ⟨SpaceMarine⟩ I am
<queqiao-> ⟨Al2Me6⟩ Picture?
<queqiao-> ⟨SpaceMarine⟩ cant get the flight plan to go
<queqiao-> ⟨Al2Me6⟩ * Screenshot?
<queqiao-> ⟨SpaceMarine⟩ will get one for you once i do another run
<queqiao-> ⟨SpaceMarine⟩ give me a minute
<queqiao-> ⟨Stonesmile⟩ And you are launching into current inclination and a 200 km parking orbit?
<queqiao-> ⟨SpaceMarine⟩ yes
<queqiao-> ⟨SpaceMarine⟩ Another, mechjeb isnt allowing me to warp to principia nodes anymore
<queqiao-> ⟨SpaceMarine⟩ not sure why
<queqiao-> ⟨Al2Me6⟩ Sounds like you need tracking station upgrades to unlock flight planning.
<queqiao-> ⟨SpaceMarine⟩ it seems to be working now, i am using an srb so am a little less flexible obviously, is it normal in principia that you dont need as much delta v to reach the moon
<queqiao-> ⟨SpaceMarine⟩ it looks like its asking for 3130
<queqiao-> ⟨SpaceMarine⟩ ish
<queqiao-> ⟨pEdro⟩ depends on the window
<queqiao-> ⟨pEdro⟩ 3130 is on the low end
<queqiao-> ⟨pEdro⟩ depends on the window and burntime
<queqiao-> ⟨SpaceMarine⟩ am actually overshooting with this
<queqiao-> ⟨SpaceMarine⟩ ie a gcrc delta v wise (of course there is variance
<queqiao-> ⟨pEdro⟩ plan for 3150 for short burning stages, 3200-3250 for long burning ones
<queqiao-> ⟨pEdro⟩ with a srb you want more than 3150
<queqiao-> ⟨SpaceMarine⟩ this gcrc has 3144m/s
<queqiao-> ⟨SpaceMarine⟩ but to get close to the moon
<queqiao-> ⟨SpaceMarine⟩ it wants more like 31:30
<queqiao-> ⟨SpaceMarine⟩ 3130*
<queqiao-> ⟨pEdro⟩ the higher the ∆V, the lower the deviance from engine variance
<queqiao-> ⟨Al2Me6⟩ (Remember to turn on inertially fixed maneuver too)
<queqiao-> ⟨SpaceMarine⟩ what does inertially fixed mean
<queqiao-> ⟨SpaceMarine⟩ hell might as well post thes creenshot with
<queqiao-> ⟨pEdro⟩ it keeps pointed the same way
<queqiao-> ⟨SpaceMarine⟩ all my probably bad settings
<queqiao-> ⟨SpaceMarine⟩ my ui is a mess haha
<queqiao-> ⟨pEdro⟩ inertially fixed is basically stock nodes
<queqiao-> ⟨Al2Me6⟩ And a normal maneuver is WRT the moving Frenet frame, so tangent points exactly prograde during the entire maneuver.
<queqiao-> ⟨Al2Me6⟩ It's more efficient, but you can't do that with spin-stabilization.
<queqiao-> ⟨SpaceMarine⟩ this thing is stable without spin stabilization
<queqiao-> ⟨pEdro⟩ simpler words: normal maneuver assumes a constant orientation in relation to your velocity vector
