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-> ⟨goblijn22⟩ "Sir, you need to pay the cheese tax before I can let you continue watching these.... cat videos..."
<queqiao-> ⟨maxsimal⟩ The cheese tax is clearly being overpaid, given Nick's chonkt frame.

<queqiao-> ⟨goblijn22⟩ I need principia wisdom. Im experimenting with lunar orbits. how do i get to a frozen orbit from a TLI or earth orbit?
<queqiao-> ⟨goblijn22⟩ i was thinking that my launch inclination would need to be the inclination of the frozen orbit
<queqiao-> ⟨goblijn22⟩ but that seems unlikely
<queqiao-> ⟨goblijn22⟩ and i missed the moon entirely on that launch
<queqiao-> ⟨goblijn22⟩ AGAIN
<queqiao-> ⟨goblijn22⟩ i cant select the moon as a target its over
<queqiao-> ⟨goblijn22⟩ nvm
<queqiao-> ⟨goblijn22⟩ damn that was a lucky from a tli burn
<queqiao-> ⟨egg⟩ Use the final orbit analyser from the flight plan.
<queqiao-> ⟨goblijn22⟩ is artemis blessing me the inclination is getting closer to the frozen orbit just by spending time at luna
<queqiao-> ⟨egg⟩ Again, use the Principia orbit analyser, not the MJ orbit info…
<queqiao-> ⟨goblijn22⟩ i have no idea what any of this means
<queqiao-> ⟨goblijn22⟩ i know what the +/- symbol means
<queqiao-> ⟨egg⟩ > i have no idea what any of this meansYou certainly know what most of it means, since these are the same words you see in the MJ window. Also, see https://github.com/mockingbirdnest/Principia/wiki/Orbit-analysis.
<queqiao-> ⟨goblijn22⟩ i think 2 years in lunar orbit is reasonable
<queqiao-> ⟨Damien⟩ You can adjust your moon intercept l to any inclination you like with a mid-course trajectory manoeuvre very easily.
<queqiao-> ⟨Damien⟩ -l
<queqiao-> ⟨goblijn22⟩ i was able to get to roughly 50 degrees just from tli
<queqiao-> ⟨goblijn22⟩ mustve been luck
<queqiao-> ⟨Damien⟩ Nice
<queqiao-> ⟨Damien⟩ Sounds like an opportunity for _learning_
<queqiao-> ⟨goblijn22⟩ well i know what alot means
<queqiao-> ⟨goblijn22⟩ i just dont know what a knodal precession means
<queqiao-> ⟨goblijn22⟩ but judging by the number it gives im thinking its a change of inclination?
<queqiao-> ⟨Damien⟩ We have the technology (google)
<queqiao-> ⟨goblijn22⟩ meh
<queqiao-> ⟨goblijn22⟩ final orbit!
<queqiao-> ⟨goblijn22⟩ so... like i said, change of inclination over time?
<queqiao-> ⟨Damien⟩ Imagine that you get into an orbit where the AN/DN precesses around the earth at the same rate the earth goes around the sun. This would allow the orbit to always be aligned relative to the sun
<queqiao-> ⟨Damien⟩ That's a sunsynchronous orbit
<queqiao-> ⟨Damien⟩ It's the inclination doesn't change, the point on the earth the orbit crosses the equator does
<queqiao-> ⟨egg⟩ No, it is a change of longitude of the ascending node.
<queqiao-> ⟨Damien⟩ * The
<queqiao-> ⟨egg⟩ (Hence the word _nodal_. Apsidal precession would be the variation of the argument of periapsis, but its value is rarely useful so we do not report it.)
<queqiao-> ⟨goblijn22⟩ what should i try next
