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…

⟨AgustinCaniglia⟩ egg all your 2023 updates are marked as 2022 in the ksp forums.
<queqiao->
⟨AgustinCaniglia⟩ You might want to fix that because like me, there could be others that think you haven't updaed the mod since 2022
<queqiao->
⟨AgustinCaniglia⟩ Unless you don't want to face the reality that we are indeed in 2023
<queqiao->
⟨egg⟩ Fixed, thanks.
<queqiao->
⟨egg⟩ I should do something about this OP, it is an unmaintainable mess.
<queqiao->
⟨thunkii⟩ ⟪night_beast⟫ Man.. I'm going to have so many […] ⮪ https://youtu.be/UCMSDvp-n74 this helps explain stuff too
<queqiao->
⟨patrikcath⟩ Oh, I just remembered something I was wondering about a while back.
<queqiao->
If you have a geostationary satellite it obviously stays above the same location on Earth. If you have a geosynchronous one with a non-zero inclination it wobbles up and down between two locations, how far they are depends on its inclination.
<queqiao->
What happens if you have a satellite in a geosynchronous altitude, but 90-degree inclination? Does it start behaving like a regular polar satellite or does it only move on one side of the planet? I think about this way too much
<queqiao->
⟨thunkii⟩ big figure eight basically
<queqiao->
⟨thunkii⟩ crosses the equator at the same point every 11h58m
<queqiao->
⟨patrikcath⟩ Good way to get a lot of coverage with just one satellite I guess
<queqiao->
⟨egg⟩ (which you look at in-game, though admittedly that requires starting KSP.)
<queqiao->
⟨egg⟩ ⟪patrikcath⟫ Good way to get a lot of coverage with […] ⮪ If you care about both hemispheres equally and don’t need to be moving slowly with respect to the ground and are fine with being far, far, away, I guess you can use a constellation of a few of these. This is not a very common combination of requirements.
<queqiao->
⟨egg⟩ (I need to get back to #σκοπός so we can instill a sense of what concerns go into orbit design into people…)
<queqiao->
⟨thunkii⟩ as inclination goes to 180 degrees, the figure eight just gets bigger until it wraps twice around the equator
<queqiao->
⟨Quattro rumbass⟩ anyone care to explain to me how you "get to" lagrange points
<queqiao->
⟨Butcher⟩ Fly in the right direction.
<queqiao->
⟨Butcher⟩ When you get there, stop. The trick is knowing the right direction.
<queqiao->
⟨Soviet Onion⟩ ⟪Quattro rumbass⟫ anyone care to explain to me how you […] ⮪ play around with the trajectory and see if you can get into an "orbit" when going int he right direction as Butcher said
<queqiao->
⟨the rocket science kid⟩ the new rotating pulsating frame may also help with determining if you’re there yet
<queqiao->
⟨pEdro⟩ ⟪Quattro rumbass⟫ anyone care to explain to me how you […] ⮪ when the line wiggles its way into a new direction, its likely near a lagrange point
<queqiao->
⟨pEdro⟩ good, theres a point both directions
<queqiao->
⟨Damien⟩ ⟪Quattro rumbass⟫ is my vessel's trajectory passing […] ⮪ Yeah you're passing through the x on the left which I believe is the sun-earth L2 point. You need to get to that point without moving away from it so you need very little velocity as you enter it, or do a deceleration burn to capture into it
<queqiao->
⟨Damien⟩ For sun-earth l-points I generally eject to a trajectory that just about reaches the point or just beyond it with some lateral velocity so I slide into an orbit easily. Often this means I eject slightly offset from the earth-sun line and then curve into the orbit at my ap when I'm moving slowly
<queqiao->
⟨Damien⟩ Not sure if that's the best way but it works
