This is a fun campaign idea! I like the options presented to the players as to what resources they have to choose.
It seems quite reasonable to run, although does rely on the GM to come up with the specifics of the actual journey itself. It could probably use more details on the ship itself and the machinery/equipment the players have access to. That would also help in terms of upgrading and maintaining the ship.
I also found the monospaced text a bit hard to read - maybe because of the character spacing? It could also probably benefit from a black-and-white/no background version for printing.
