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…
<queqiao->
⟨ashnoom⟩ how accurate is the "transfer window planner" with principia?
<queqiao->
⟨lpg4999⟩ sufficiently
<queqiao->
⟨ashnoom⟩ figured my issue out, I had the wrong inclination. I assume the TWP to use the given orbits inclination. But apparantly it can launch higher than the parking orbit
<queqiao->
⟨aldi⟩ LAN and angles work about right. Tend to find I need an extra 100m/s on what it suggests for ejection delta v
<queqiao->
⟨ashnoom⟩ _potential_ parking orbit
<queqiao->
⟨ashnoom⟩ That is indeed what I just figured. I launched to correct inc, and I hadd to add ~100m/s for a venus transfer
<queqiao->
⟨ashnoom⟩ first launch I launched to a different inc, (given parking orbit inc) and I had to add ~2000m/s, and the flight duration changed from 205 to 150 😮 and I was like, this can't be right
