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…
<queqiao--> <R​D-​30​1 ​wo​rs​hi​pp​er​> What is it with the principia channel and posting cat pics
<queqiao--> <R​D-​30​1 ​wo​rs​hi​pp​er​> Genuinely curious
<raptop> This is the cat pictures channel, though discussions of N-body physics in KSP are also on topic
<queqiao--> <C​la​ye​l> probably originates to this
<queqiao--> <G​oF​or​PD​I ​(l​es​s ​dr​ag​=m​or​e ​fa​st​er​)> Jesus you scrolled back to 2019
<queqiao--> <r​ap​to​p ​| ​²³​⁹P​u ​po​we​re​d> I mean, we've both sort of been Like That. From 2014-10-07: https://media.discordapp.net/attachments/480397772248580098/1363684010945155255/2014-10-071.jpg?ex=6806ed34&is=68059bb4&hm=62743b77e90d791e0b1022f9906af15ffc7f6e959d677ea266fe04f368d40167&

<queqiao--> <C​la​ye​l> its the first pinned message
<queqiao--> <C​la​ye​l> or just look up "cat" in this channel, theres 1000 results :D

<queqiao--> <K​ag​a> Is there a general/summary chart on what altitude is equivalent to what inclination? I tried reading the pdfs but i cant understand anything xd
<queqiao--> <N​az​fi​b> The required inclination for a sun-synchronous orbit depends on the orbital altitude, with higher orbits requiring a larger (i.e. more retrograde) inclination. Only in that range are the inclination and altitude such, that the whole orbit is outside the Earth's shadow even during the solstice.I don't have any good pictures to help you visualise, but if you want the full details:

<queqiao--> <N​az​fi​b> The Wikipedia article for Sun-synchronous orbit contains a few example altitude/inclination combinations, as well as formulæ that will let you determine the required inclination for any altitude. Start at one of those combinations, and adjust with RCS and the Orbit Analyser to make your orbit exactly sun-synchronous — you want to make the mean local time at your ascending/descending nodes vary as little as possible.

<queqiao--> <e​zs​na​ck​> whats the best reference frame to understand where the sun will be when i get to the moon? earth sun? its a bit confusing :c
<queqiao--> <m​ad​le​e> idk of a better way than just eyeballing it in earth-moon or moon-centered inertial, the terminators move ~45° west over a 3.5 day transfer. sim it if you need precision e.g. landing near poles
<queqiao--> <h​yn​> hi, quick question: How can I keep a small probe sun oriented in big time warps? I have RCS, electricity and everything, and I always Kill rotation before warping
<queqiao--> <M​me​ri​di​an​> spin it up slightly (like 3-4deg/s) better yet, orient to your best solar panel exposure possible and then return to space center. Kerbalism will maintain the same exposure while the craft is unloaded.
<queqiao--> <h​yn​> thank I will try that
<queqiao--> Reply to "e​zs​na​ck​: whats the best reference frame to understand where the sun will be when i get to the moon..."
<queqiao--> <k​uz​in​at​0r​> Moon surface fixed I guess
<queqiao--> <k​uz​in​at​0r​> Or just moon centered, if you don't care about the landing zone
