Just a note, this is not fixed. The Muluna Mod's Advanced Space Research is still locked behind the Exploration Science Pack, which requires completing (at minimum) two additional planets before it can be researched. (I say at minimum because it can be set to scale with the number of added planets.) As such, until you have unlocked the required number of planetary science packs, it still requires importing Space Science to Neumann V from Muluna if you're going to research there. (Admittedly, I would prefer just being able to use the Nanite Science Packs in labs on Nauvis, just because it's more convenient to use that as a research hub for everything, but that's a separate matter entirely.)
