⟨Laufer⟩ any tips on launching a satellite into earth moon L1 point?
<queqiao->
⟨Zeusbeer⟩ Go to L2 first and you can for very little deltaV easily switch to L1 by tweaking the noodles iirc
<queqiao->
⟨Zeusbeer⟩ There might be a direct way so correct me if I'm wrong
<queqiao->
⟨Butcher⟩ Why would you go to L2?
<queqiao->
⟨Laufer⟩ ⟪Zeusbeer⟫ Go to L2 first and you can for very […] ⮪ do you enter lunar orbit before doing a burn to L2 or can you do a burn from a lunar flyby from a lunar insertion burn?
<queqiao->
⟨Zeusbeer⟩ I don't go there often, wasn't there a video that someone made
<queqiao->
⟨egg⟩ ⟪Butcher⟫ Why would you go to L2? ⮪ Yeah L1 is closer energetically, so it seems odd to go via L2
<queqiao->
⟨Butcher⟩ I did wonder if I was missing something.
<queqiao->
⟨Butcher⟩ But also, does L1 have any particular utility?
<queqiao->
⟨egg⟩ Earth sun yes, unsure about earth moon though.
<queqiao->
⟨egg⟩ (Earth sun for solar and earth observation)
<queqiao->
⟨egg⟩ EPIC/DSCOVR
<queqiao->
⟨Butcher⟩ Yeah E-S makes total sense, E-M seems less useful than ground based solutions.
<queqiao->
⟨Sumguy⟩ Earth Mars Lagrange points are highly unstable, afaik
<queqiao->
⟨Sumguy⟩ E-L L1 is good for a lunar space teather
