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…

⟨pEdro⟩ Because i dont feel like building a Saturn-V class vehicle and pad, ive decided to do a EOR/LOR combined mission architecture, issue is, im at the cape, whats the best way to make sure that the very first module sent up is in the right LAN for a efficient luner transfer 100 days in the future ?
<queqiao->
⟨pEdro⟩ i felt like sticking with Titan IIIs
<queqiao->
⟨pEdro⟩ * III
<queqiao->
⟨pEdro⟩ * III, also known as SSLS
<queqiao->
⟨pEdro⟩ with some mild upgrades, im able to do 17t to LEO, enough to do a 4 launch moon mission, 3 of those will have to dock in LEO to get the heavy lander going moonwards
<queqiao->
⟨leudaimon⟩ I never figured how to work with LAN precession for EOR
<queqiao->
⟨leudaimon⟩ * EOR, regardless of whether you're in a site that allows for in-plane transfers
<queqiao->
⟨Butcher⟩ I would probably go LOR tbh.
<queqiao->
⟨pEdro⟩ problem is, my lander is about how much i can lift in one launch
<queqiao->
⟨Butcher⟩ Yeah 17t is basically just a lander. D:
<queqiao->
⟨pEdro⟩ maybe noodling around earth/sun L1/2 could help get my in the right plane ?
<queqiao->
⟨pEdro⟩ i have about 2t of spare mass on the third EOR launch where i could pack solar and stuff for the longer journey
<queqiao->
⟨Butcher⟩ Meanwhile I'm keeping launch masses under 2000t. :-p
<queqiao->
Though I did need to buy an unlimited pad as my rockets are too tall for the 2000t pad. 😦
<queqiao->
⟨Zavian⟩ I haven't played with Principia, but wouldn't any LAN basically be correct for lunar transfer roughly twice per month?
<queqiao->
⟨Butcher⟩ Yes I think so. Worst case you sit in orbit for 14 days, that might be a problem though.
<queqiao->
⟨Δv1㎧⟩ Butcher's addon can give you a launch time and inclination given a transfer time. Could you simply set the transfer time to be loiter time + actual transfer time and launch to what it tells you from there?
<queqiao->
⟨Stonesmile⟩ Yesn't. There is also the precession of the LAN
