This feels like the grown-up ideological successor to the International Space Settlement Design Competition for high school students. That was (is? anyone still in the know?) a competition that ran for years out of NASA Houston as a pet project of some engineers and contractors who wanted to engage and cultivate the next generation of aerospace minds.
Teams would submit proposals for the design of a permanent space settlement (sometimes on the surface of a body, sometimes orbiting). Winners from across the world were invited to compete together live in 4 huge multi-national teams to design and pitch another settlement over a long sleepless weekend. As a two-time finalist, I can say it was an incredible experience for so many reasons.
This new competition seems like its goal is to actually take the design/ideation of working professionals as a serious output, as opposed to the educational value of simulating this sort of thing for students, which is what drove the ISSDC.
