The core station you inhabit must reproduce all the necessities for human habitation. The core section of the station houses the working compartment made up of living and operational quarters and is the main habitable section for the crew.
Crew members cabins each contain a chair, a sleeping bag, and a porthole.
The personal hygiene area holds a toilet, sink, and shower, and the galley consists of a table, cooking elements, and trash storage. The operations area is the control area for the entire Mir complex. Here the crew can monitor and command core systems, science equipment and facilities and the piloting station. The multiple docking ports of the transfer compartment allow for the addition of secondary station modules or transport craft. The intermediate compartment is a pressurized tunnel 6 feet in diameter that connects the working module to the aft docking port.
