This is cool, and it looks functional as a research vehicle. I like the way you showed the scale, with the person in the window, but I wonder, do they live in it? Or would they have to get out and camp beside it?
I did think that the back part looked like a possible sleeping space, though I imagine that much like a submarine, the inside would be somewhat claustrophobic. I sure hope those four people like each other! I think that the "supplies attic" on the top actually makes it seem more grounded in reality.
Haha, I imagine claustrophobia would be an issue, indeed. But travelling to different worlds, with completely different biology require quite closed vessel environment I would deduce. Yeah, seeming this would be a compact "house" for research, excursion, and "cross-country" travelling, I wanted to give it a more down-to-earth type of design.
