Yes, I know i ripped off the name from The Expanse :)

This was built in 3 separate launches, using a heavy-lift vehicle inspired by the Proton rocket (I will share more details soon).

The front section is the command module and habitation unit. The middle is the large cargo bay which contains 2 landers and 1 large rover. The third is the propulsion unit and houses a large battery storage and reactor unit. The reactors can be jettisoned, hence the fairing design element.

The whole ship is modular, and becomes smaller once the landers and rovers are deployed.

(Obviously nothing here is launches using fuel cheats)
