Sorry, I was just scrolling through all of the previous comments, and I just thought, there are so many great ideas, but you can't fit them into one spacecraft. So why not make more? I was thinking once you're completely done with the Asimov, then you could make the Asimov-XL (Or something to that effect), with the greenhouse, and centrifuge, and service bay, and cupola, and other large things with all of the normal parts much bigger, and the regular Asimov could be a shorter range thing, like Duna or Eve Maximum, whereas the XL could go to Dres, Jool, Eeloo, Moho... or even farther. Maybe you could integrate DeepFreeze Continued, and go to other solar systems with Kopernicus. I would say finish the Asimov first, but it may be something you want to think about later.
