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…

⟨maxsimal⟩ The cheese tax is clearly being overpaid, given Nick's chonkt frame.

⟨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⟩ so... like i said, change of inclination over time?

⟨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->
⟨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.)
