Airlock

A possible airlock, with indexed and double connectors. Services include Communications, power, potable water, waste water and heat transfer fluid in and out.

Airlocks will be required to access the settlement from the Martian surface, or to connect up vehicles to one another or to habitats.

A rectangular airlock with a double set of connectors can provide circuit redundancy as well as androgynous connections between any pair of airlocks. Centering would need to be done mostly using an adjustable suspension on vehicles, although the facing connection could have about 15 degrees of travel and perhaps up to 20 cm of travel in a flexible bellow sleeve.
