Two more grav cores and quite a bit of time later the ship has seen some upgrading and re-configuring.
The freezer is now much, much larger so we can stockpile more raw food and stay in space longer.
The medbay now has two additional beds.
The ship now has its small thrusters back and more fuel space.
The power supply has been doubled.
There are two additional single bedrooms.
Both airlocks are now only for suits and weapons.
I think we're ready to go back up.
