Hummm.... As SpaceX said, there's only 6 months left to colonize Mars, by then we all known Elon Musk will declare independence and wage war to all mankind. Luckily Japan is building the first Gundam recently, I guess there's always hope in the dark
If there's one thing I've learned watching science fiction movies it's that spaceships should have an endless amount of long, very wide and high ceiling corridors. It looks like that consideration hasn't been made in this design.
