02:33 <queqiao-> ⟨Iodyne⟩ I've noticed apsidal _and_ nodal precession are very prevalent with Principia, but, I have yet to notice any axial precession (though I admit I have not examined overtly closely, and have only run simulation for about 5000 years). Can anyone tell me, is it present?

03:06 <queqiao-> ⟨Al₂Me₆⟩ Of the planets? Not implemented AFAIK.

03:32 <queqiao-> ⟨Zavian⟩ From memory, there is no actual axial tilt of any planet in KSP. The game engine doesn't support it. Does principia change that? And without axial tilt, I'm not sure how you could have axial precession.

03:33 <queqiao-> ⟨Al₂Me₆⟩ Yes, Principia is a big enough 🔨 to fix that.

03:34 <queqiao-> ⟨November (she/her)⟩ Though I think it doesn't work for Earth and so they had to tilt the solar system instead of Earth's axis

03:34 <queqiao-> ⟨Al₂Me₆⟩ ⟪November (she/her)⟫ Though I think it doesn't work for […] ⮪ That would be how stock RSS is implemented.

03:36 <queqiao-> ⟨Zavian⟩ Yet another reason to add principia next time I'm starting a new career.

05:10 <queqiao-> ⟨Iodyne⟩ Yes obviously I am referring to axial tilt as implemented by Principia. Hence posting in the principia channel. I've been making tilt configs for stock and multiple planet packs.

12:34 <queqiao-> ⟨Proton | Mod.ROTanks Protester⟩ Any guides for a free-return launch? What should be the plane of the moon, etc?

12:34 <queqiao-> ⟨Proton | Mod.ROTanks Protester⟩ * phase

12:34 <queqiao-> ⟨Proton | Mod.ROTanks Protester⟩ +flyby

12:34 <queqiao-> ⟨test_account⟩ the trajectory doesn't care about the phase of the moon 🤔

12:34 <queqiao-> ⟨Proton | Mod.ROTanks Protester⟩ -What should be the phase of the moon, etc?

12:35 <queqiao-> ⟨Proton | Mod.ROTanks Protester⟩ Yes, but is there anything I should know that can indicate me how to do a free return?

12:35 <queqiao-> ⟨test_account⟩ there are two types of it i think, i've only done one, which is a wide loop around the moon

12:36 <queqiao-> ⟨Damien2⟩ ⟪Proton | Mod.ROTanks Protester⟫ Yes, but is there anything I should […] ⮪ https://github.com/mockingbirdnest/Principia/wiki/A-guide-to-going-to-the-Mun-with-Principia

12:36 <queqiao-> ⟨test_account⟩ you perform a TLI with slightly higher than normal dV and like 5000km moon periapsis i think

12:36 <queqiao-> ⟨Damien2⟩ there's a free return tutorial in there

12:36 <queqiao-> ⟨test_account⟩ and tune the trajectory until it gets you back to earth after that loop

12:37 <queqiao-> ⟨Damien2⟩ yeah, playing with burn start time and prograde velocity usually tweaks it back and forth

12:38 <queqiao-> ⟨Damien2⟩ if done right you should be able to TLI then do nothing until you hit atmo at the end

12:38 <queqiao-> ⟨test_account⟩ it can be difficult to make lunar periapsis low enough to fulfill the contract, in this case corrections will be needed

12:42 <queqiao-> ⟨test_account⟩ Now that I think about it, the phase of the moon actually matters if you want the reentry during daytime

12:42 <queqiao-> ⟨test_account⟩ -the

12:43 <queqiao-> ⟨test_account⟩ or moon flyby during local daytime too
