<discord-> J​ustMozzie. — hey so im still sort of struggling with principia, especially with getting encounters with the moon, i can get them, i just tend to go way above the moon and then fall back down to eventually get close to the moon.
<discord-> J​ustMozzie. — how do i minimize this as much as possible?
<discord-> J​ustMozzie. — is there any tutorial videos?
<discord-> A​l2Me6. — Sounds like you need a mid-course correction
<discord-> A​l2Me6. — What do you mean “way above”?
<discord-> J​ustMozzie. — my apogee for my spacecraft goes above the moon, which is okay for my previous lunar impact missions, but this time i want to put a satellite around the moon, and i want to minimize my velocity when approaching the moon so i can get a closer apoapsis around the moon.
<discord-> J​ustMozzie. — and i'd rather avoid spending multiple orbits in a parking orbit waiting for the LAN, because i'm not packing that much electrical charge for the transfer stage.
<discord-> g​mckinnon. — here is my way of getting into a moon orbit, it might help you. Hopefully others can chime in with any improvements
<discord-> g​mckinnon. — 1. Launch into the LAN of the moon - there is a kos script that is really useful that time warps until the right LAN to launch at 28 degrees. Or there is another script that tells you the degrees to launch at that point in time. Either works.
<discord-> g​mckinnon. — 2. Get into LEO - I use PVG
<discord-> g​mckinnon. — 3. As soon as in orbit, create your flight plan for a prograde burn of around 3140, move around the time to burn and increase/decrease the burn slightly until you get your desired periloon.
<discord-> g​mckinnon. — 4. Start your burn -- I manually do this around 1-1.5 seconds before principia says to which allows for engines to spool up
<discord-> g​mckinnon. — 5. close to the end of the burn I switch to slow mode time (needs a mod) and as soon as I get close to the desired periloon stop the burn
<discord-> g​mckinnon. — 6. Use rsc to adjust as needed (you shouldn't need much)
<discord-> g​mckinnon. — 7. create flight plan for your capture burn (making sure you will have comms visibility at the time.

<discord-> g​mckinnon. — this works quite well for me, the key is starting the burns at the right time (as a few seconds can change your fight path a lot) (edited)

<discord-> J​ustMozzie. — this is great! could i get a link or something to that kOS script? also is there any way to not use kOS, im not versed in kOS at all...
<discord-> S​umguy. — look for links posted by Butcher
<discord-> J​ustMozzie. — i think i found it

<discord-> K​obymaru. — how does the script calculate it?
<discord-> K​obymaru. — the launch LAN from the moon position/orbit
<discord-> S​tonesmile. — IIRC Butchers script calculates the plane intersecting the centre of the Earth, the moons position in 4 days and the vessel's possition
<discord-> K​obymaru. — I see, thanks
<discord-> K​obymaru. — that's sorta what I do manually (without calculating anything)
<discord-> K​obymaru. — that's sorta what I do manually (without calculating LAN) (edited)
<discord-> S​tonesmile. — Do note that Butchers script gives you the inclination to launch into *Right Now*, if you want a script that warps to the appropriate time for a launch East, then ItsRyan's script does that; https://github.com/ryanc55/KOS-Scripts/blob/master/moonlaunchwindow.ks
<discord-> K​obymaru. — oh, awesome
<discord-> K​obymaru. — where would I find butchers script?
<discord-> S​tonesmile. — Here is the link to his repo, it's in there somewhere; https://github.com/RCrockford/kOS-Scripts
<discord-> K​obymaru. — thanks
<discord-> K​obymaru. — So I'm a bit emberassed to ask this question, but I gotta do it anyway...
<discord-> K​obymaru. — I understand what the LAN is, but it is defined via a plane of reference and a reference direction. What are the reference plane and reference directions?
<discord-> K​obymaru. — What is it when I'm in LEO and what is it when I'm around the sun?
<discord-> K​obymaru. — Is it the equatorial plane? The Plane of ecliptic? The plane of the milky way?
<discord-> S​tonesmile. — LAN is in reference to the First Point of Aries; https://en.wikipedia.org/wiki/First_Point_of_Aries
<discord-> K​obymaru. — Always?
<discord-> K​obymaru. — in every orbit?
<discord-> S​tonesmile. — I think so, LAN is just what angle your ascending node (across the equator of a body) and the first point of aries form
<discord-> K​obymaru. — ok, so the reference plane is the equatorial plane of the central body?
<discord-> S​tonesmile. — Yes, as far as I understand it
<discord-> K​obymaru. — and if the First point of Aries is not on that plane? would it be the projection of the reference direction onto that plane?
<discord-> S​tonesmile. — I would guess it uses the projection on to that plane, but I think google knows more than me 😅
<discord-> d​enebw. — It is on the celestial equator, which is the projection of equatorial plane
* nyantop thought that the first point of aries was just the ascending node for the eggliptic?
<nyantop> anyway, the plane gets defined by the reference frame, so you'll need to check which one you're using (aaaa). The direction should follow the right-hand rule
<discord-> K​obymaru. — thanks
