Work on the exterior is more or less done now, except for the RCS and the (suspect) high gain antenna.
I will now be working primarily on the VC, which will have four levels, from front to back:
Crew deck: Will house some cargo storage, sleeping facilities for the crew of 4 and of course the control cockpit for the spacecraft. In the previous pusher design the cockpit rotated 90 degrees so that the pilots would not be hanging in their seat straps during cruise. In the new design, the pilots just lie on their backs.
Storage and logistics deck: Houses some of the life support systems and the food storage.
Recreation deck: Houses excersise equipment, galley/entertainment area and toilet/shower facilities designed for use in both full and microgravity.
Passenger deck: Houses space for 14 passengers in bunks. Bunks double as acceleration couches during other phases of the flight and provide a degree of privacy. Passenger cargo is stored below each bunk.
