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-> ⟨byte⟩ one more complex variable sensor 😄
<raptop> cat
<queqiao-> ⟨Daniel27⟩ Can you Install Principia after you have played for a while?
<raptop> Yes, though make sure you have backups of your saves and expect bad things to happen to any craft on interplanetary trajectories
<raptop> (If nothing is in orbit or the like, it should be fine)
<queqiao-> ⟨Daniel27⟩ I have just 2 satellites around earth
<queqiao-> ⟨nvv⟩ Well their orbits might be changed quite a bit
<queqiao-> ⟨Daniel27⟩ I have just installed principia and this is what happened :
<queqiao-> ⟨Daniel27⟩ The Sun is orbiting the Earth
<queqiao-> ⟨Daniel27⟩ But why the Sun (and everything else) is orbiting the Earth?
<queqiao-> ⟨test_account⟩ Because this is what you see from the Earth, every day
<queqiao-> ⟨lpg⟩ that would be the Concepts page, which you'll come across in that wiki
<queqiao-> ⟨Daniel27⟩ ok
<queqiao-> ⟨SpaceMarine⟩ because a thing called frames of reference exist
<queqiao-> ⟨Daniel27⟩ Can you use Mechjeb to execute the maneuvers ?
<queqiao-> ⟨Stonesmile⟩ Yes, but you need to plan them on your own
<queqiao-> ⟨Stonesmile⟩ * own, using Principia's tools
<queqiao-> ⟨test_account⟩ mechjeb maneuver node editor definitely has an option called "Execute next principia node"
<queqiao-> ⟨test_account⟩ I don't know how well it does that though
<queqiao-> ⟨Stonesmile⟩ Pretty well. It knows about spool up time and burns the requested dV, not the requested time
<queqiao-> ⟨test_account⟩ Does it also understand inertially fixed / non inertially fixed maneuvers?
<queqiao-> ⟨Stonesmile⟩ Principia handles that
<queqiao-> ⟨test_account⟩ You mean, by showing the maneuver on the navball? So that the marker moves during the burn if the maneuver is not inertially fixed, and MJ follows the changing direction?
<queqiao-> ⟨test_account⟩ Does that work also when there is no contact with the craft?
<queqiao-> ⟨Stonesmile⟩ Yes, and yes, and yes
<queqiao-> ⟨test_account⟩ ok, I see 🙂
