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->
⟨nazfib⟩ Either something on your probe got heavier, or the root part was wrong previously and you fixed it before building the rocket.
<queqiao->
⟨KerbalMario (please ping reply)⟩ hm, do tanks lose fuel like leakage?
<queqiao->
⟨KerbalMario (please ping reply)⟩ may sound stupid
<queqiao->
⟨KerbalMario (please ping reply)⟩ but i had happen
<queqiao->
i was idling (engine off) and losing 0.00 LOX
<queqiao->
⟨razgriz16⟩ Cryogenic propellants leak
<queqiao->
⟨ezsnack⟩ or boiloff
<queqiao->
⟨razgriz16⟩ * boiloff
<queqiao->
⟨nazfib⟩ Cryogenic resources boil off over time. That means any resources with "Liquid" in the name.
<queqiao->
⟨nazfib⟩ And that is indeed a third option for why you're losing Δv.
<queqiao->
⟨nazfib⟩ * you could be
<queqiao->
⟨KerbalMario (please ping reply)⟩ liquid oxygen the rd0105 uses. that seems to be it. anyhow i can prevent that?
<queqiao->
⟨test_account9540⟩ don't spend more than a couple orbits in parking orbit
<queqiao->
⟨nazfib⟩ You cannot prevent it completely. Layers of MLI can greatly reduce the boil-off rate, though. However, for the maximum 90 minutes you're spending in a parking orbit, the boil-off Δv loss should be fairly small.
<queqiao->
⟨nazfib⟩ * minimal.
<queqiao->
⟨ezsnack⟩ fairings for tli stge
<queqiao->
⟨ezsnack⟩ * stage
<queqiao->
⟨ezsnack⟩ * stage, or less hot ascent
<queqiao->
⟨KerbalMario (please ping reply)⟩ tli stage is in fiairng
<queqiao->
⟨ezsnack⟩ where is all that boiloff coming from then :v
<queqiao->
⟨KerbalMario (please ping reply)⟩ i hate pvg randomness
<queqiao->
i reverted to launch because some kraken shit happened and after 25km pvg decided to dive down
<queqiao->
⟨nazfib⟩ There is no randomness in PVG. If it does something differently, it is because the inputs are different.
<queqiao->
⟨KerbalMario (please ping reply)⟩ same settings and all
<queqiao->
⟨KerbalMario (please ping reply)⟩ and now 2nd stage randomly spinned
<queqiao->
⟨nazfib⟩ None of this is related to #principia by the way, maybe it is time to move back to #rp1-career-help
<queqiao->
⟨KerbalMario (please ping reply)⟩ ok
<queqiao->
⟨egg⟩ Yes, I was about to ask that this conversation be relocated to some appropriate place (which is not here).
<queqiao->
⟨sichelgaita⟩ Incidentally, a version of Principia that says "20230618" is, I don't know how to put it, a year old. So upgrade maybe?
<queqiao->
⟨egg⟩ Maybe we should increase the font size as the reminder gets more stale.
