<dodgethisduck> How do I get to Kerbin-Mun L2? I can find videos for L4/L5, but not L2. I need a commsat there.

<the bozo> using the kerbin-mun lagrange reference frame is very useful as it can show you the equipotentials
<queqiao-->
<dodgethisduck> Aaaaaand I just found a video after looking forever for one. 😶

<dodgethisduck> Yeah, I know that much, I just can't figure out the maneuver to get there.
<queqiao-->
<the bozo> i'm not too sure but i think you need to be orbiting the point in a retrograde direction
<queqiao-->
<the bozo> the L1 and L2 points are dynamically unstable so without constant stationkeeping you'll typically only be able to stay there for one or two orbits
<queqiao-->
<the bozo> if you're placing a permanent commsat i would recommend just putting it in a distant retrograde orbit which passes above L1 and L2 and is dynamically stable
<queqiao-->
<Nazfib> If I remember correctly, at least for the Moon in RSS; you could do it by performing a flyby in front of the Moon, and doing a small MCI retrograde burn at periselene.

<dodgethisduck> That's why we planned for an ion engine and extra monoprop for the RCS.
<queqiao-->
<the bozo> right
<queqiao-->
<the bozo> honestly just play around with weakly stable orbits around the mun near the L2 point and make a retroburn once you get close
<queqiao-->
<dodgethisduck> Do I need to have it at a certain inclination? Like if it's a halo orbit is that at zero degrees or ninety?
<queqiao-->
<the bozo> i'm fairly certain that halo orbits can be at any inclination
