raptop changed the topic of #principia to: READ THE FAQ: http://goo.gl/gMZF9H; The current version is Galileo. We currently target 1.5.1, 1.6.1, 1.7.x, 1.8.1, and 1.9.1. <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… | <egg> also 4e16 m * 2^-52 is uncomfortably large

Butcher. — Hmm, course corrections for interplanetary are bascially just pot luck right? I plan a manoeuvre then my ship rolls say 30 degrees and my approach changes by 100 Mm.
<discord-_>
Damien. — rolling using RCS? yeah it sucks when it messes up your trajectory. That's why corrections later on are a thing

Ripper2900. — Try to balance your RCS as good as possible. Both in dry COM and wet COM. Then rotational maneauvers will have a smaller effect on your trajectory.

lpg. — if you literally mean "roll" as opposted to pitch/yaw, that really shouldn't have that kind of impact
<discord-_>
lpg. — for pitch & yaw, besides improving rcs balance, there's always "use the smallest puffs possible"
<discord-_>
lpg. — SmartASS's rcs expenditure can be tuned
<discord-_>
Butcher. — I literally mean roll, though the probe wasn;t well balanced.
<discord-_>
Butcher. — Just rolling I was able to tune a Mars flyby from 180 Mm to 200 km.
<discord-_>
lpg. — To me that suggests the roll thrusters aren't symmetrically aligned and producing some translation thrust at the same time
<discord-_>
lpg. — RCS Build Aid should make that easy to spot
<discord-_>
lpg. — I've had no trouble using roll to set up a warp-friendly spin, without impacting interplanetary trajectories in any significant way

Butcher. — I was just pleased to discover I overbuilt my venus orbiter. As I had some engine troubles on launch but somehow it still has enough delta V.
