00:13 <discord-> P​aculino (ŝi/ri/she/they). — Yeah

00:14 <discord-> P​aculino (ŝi/ri/she/they). — Yeah; planning stuff gets a little harder, but choosing a good reference frame makes it easy (edited)

00:15 <discord-> d​enebw. — Landing like this can take much more Δ-v

00:16 <discord-> d​enebw. — A powered guidance takes about 1800m/s to land on the moon

00:36 <discord-> K​obymaru. — As you can see, this maneuver is for 1690 m/s. Final descent was around 150 m/s, so in total that's 1840 m/s

00:37 <discord-> K​obymaru. — Do you mean MechJeb landing guidance works on principia?

00:37 <discord-> K​obymaru. — As you can see, this maneuver is for 1690 m/s. Final descent was around 150 m/s, so in total that's 1840 m/s. (Retrograde orbit btw) (edited)

00:37 <discord-> d​enebw. — No, i wrote a new guidance with krpc

00:38 <discord-> d​enebw. — I got to review my video to check dv

00:40 <discord-> d​enebw. — It seems that it only took 1657m/s from a 30km orbit

00:45 <discord-> l​pg. — that would seem mathematically impossible, given that's about what the _horizontal_ velocity alone is

00:45 <discord-> l​pg. — (1654 in that screenshot)

00:47 <discord-> d​enebw. — Maybe the delta info is incorrect?

00:47 <discord-> P​aculino (ŝi/ri/she/they). — Almost certainly

00:47 <discord-> K​obymaru. — mind you i'm going retrograde. But I'm having a hard time picturing an under 1700 landing

00:47 <discord-> d​enebw. — https://www.youtube.com/watch?v=ui90zUQ5yFo&t=20

00:49 <discord-> d​enebw. — Oh it should be 1739

00:52 <discord-> l​pg. — that's more believable. I generally budget 1800

00:56 <discord-> d​enebw. — i made this mainly to avoid driving rover tens of kilometers to the site

01:00 <discord-> K​obymaru. — The Principia full-stop method combined with trajectories in-flight display works pretty well for targeted landings. Does need more dV though, I budget 1900 so I'm safer from screwups and more time for corrections

01:00 <discord-> K​obymaru. — it's mostly manual though. I kind of want to stay away from kOS and krpc shenanigans

01:02 <discord-> l​pg. — with some way to put a X on the target spot (I use MJ's 'pick target on map') to have a _clear_ goal for the principia trajectory, I've been able to get hundred-meter accuracy without scripting

01:02 <discord-> l​pg. — the stock indicators (nav points or vessel icons) are just garbage for the task

01:03 <discord-> K​obymaru. — 61m is my record

01:03 <discord-> K​obymaru. — https://cdn.discordapp.com/attachments/480397772248580098/846191664312877066/screenshot464.png

01:04 <discord-> l​pg. — my record was landing literally on top of the target vessel, but that was a fluke. (and didn't exactly count as an unmitigated success)

02:38 <raptop> It's fine, just a little burnt

06:14 <discord-> B​utcher. — Retrograde on the Moon is about a 3 m/s difference.

09:56 <discord-> (​ᴇxᴘᴇʀɪᴍᴇɴᴛᴀʟshells). — the moon isn't very big and doesn't rotate very fast

15:49 <raptop> Hrm, the difference for Jupiter is over 24 km/s

15:49 <raptop> (...not that you'll be able to escape)

20:01 <discord-> Z​eusbeer. — hmm

20:01 <discord-> Z​eusbeer. — does principia model solar radiation pressure?

20:01 <discord-> D​amien. — no

20:02 <discord-> Z​eusbeer. — 😦

20:02 <discord-> Z​eusbeer. — it just sounds cool
