00:50 <raptop> I think the timetravel broke the bridge

02:02 <paculino> Is it safe from time travel now?

19:04 <queqiao-> ⟨kaborl⟩ When executing (engine is firing) a Principia maneuver, either manually or using Mechjeb, is there a way to know how much fire time is (or DeltaV) is left before completion?

19:05 <queqiao-> ⟨lpg4999⟩ he principia flight plan window tells you

19:05 <queqiao-> ⟨lpg4999⟩ * the

19:21 <queqiao-> ⟨kuzinat0r⟩ It's not accurate. Mechjeb is better

19:25 <queqiao-> ⟨test_account9540⟩ It's not accurate with roengines due to variance etc

19:42 <queqiao-> ⟨kaborl⟩ Regarding the use of KAC to "warp until X minutes before Principia's maneuver node": Thanks for the suggestion... but I'm not sure if using the KAC is very user friendly for this purpose.

20:54 <queqiao-> ⟨kaborl⟩ Can somebody share a trick to achieve a more calculated free-return (or almost one) that enters de atmosphere with just one burn from LEO? I just can't. In conic patches, it was super easy... 3174 km/s prograde and that's it. Here it seems rather complicated without adding a more meneuver vectors to get something.. Let alone ensuring good Moon's. Any trick?

20:54 <queqiao-> Also, any advice on when to launch when using the Lunar Transfer mod? Is the launch meant to happen at 0 s, or when?

20:54 <queqiao-> Anyway, thanks.

21:03 <queqiao-> ⟨test_account9540⟩ can be done prograde only, by varying dV and maneuver time

21:03 <queqiao-> ⟨test_account9540⟩ it's mostly a lot of fiddling

21:04 <raptop> ... I don't think you need to worry about silly little things like free returns with 3174 km/s (but otherwise what test_account typed)

21:05 <queqiao-> ⟨test_account9540⟩ when crewed flyby without orbit made sense from RP1 career perspective, I actually did it.. major difficulty was getting the free return trajectory with periapsis below 5000km as required by the contract, it tends to be higher, so i just made it almost free return with midcourse corrections.

21:06 <queqiao-> ⟨kaborl⟩ This is what I'm doing as well. Including midcourse correction as well. But it ain't easy...

21:06 <queqiao-> ⟨test_account9540⟩ this mission report includes some noodles 🙂

21:06 <queqiao-> ⟨kaborl⟩ There's a lot of eye balling and error-try on my proccess.

21:07 <queqiao-> ⟨_zavian_⟩ I would always assume you will need mid course corrections. In reality most burns weren't perfect.

21:14 <queqiao-> ⟨butcher6994⟩ In reality they used a mid course correction in every mission that started as free return I think.

21:28 <queqiao-> ⟨GoForPDI (less drag=more faster)⟩ In reality Apollo planned on four midcourse corrections before capturing to lunar orbit. But usually only two were done. There was also an abort burn 5 hours before capture to target a splashdown site, effectively a free return. But it could still be around 250 m/s.

21:29 <queqiao-> ⟨GoForPDI (less drag=more faster)⟩ There was also a post-capture burn in case LOI was waved off, which was closer to 400 m/s because it was meant to return faster

21:29 <queqiao-> ⟨GoForPDI (less drag=more faster)⟩ this last option is pretty much what Apollo 13 did

22:30 <queqiao-> ⟨kuzinat0r⟩ Well, just free return is easy. Plot something that will go past the Moon, then switch back to Earth centered and adjust a bit. It could even work just by hitting optimise button. The problem is the 5k km flyby range. If you don't need it, then it's easy
