Japan, South Korea, Molmol, and several other nations in and around the Pacific Ocean have pooled their space budgets, to create the Pacific Space Alliance. The chief spacecraft designer for this new group is prodigy and recent Todai graduate Dr. Kaolla Suu, Princess of Molmol. The current goal of the alliance is to reach the Moon, before the Chinese do, and before the U.S. returns. Although not known to the public, the reason for this, and in fact for the whole Alliance, is because an unmanned JAXA probe, partly designed by Dr. Suu, found something very interesting on the Moon, and they want to get to it, before China does.
What they found is up to the author. If it has anything to do with the Turtle civilization, that could be a hook to bring in Seta, Keitaro, and from there, the rest of the cast.
The story could also be combined with Rocket Girls. The anime can be found on YouTube, and is quite good. You could probably find a torrent of it somewhere, as well. By this point in the Love Hina timeline, Ema and Sarah are probably still small enough to be SSA astronauts.
