Airy-0 Crater is host to the second-largest city on Mars, the unaligned town of Port Lowell. Port Lowell is the largest fendane settlement outside of Earth cislunar orbit. The city was founded by members and supporters of the Mars Society who began migrating to Mars early, almost beating the Trekkies to the surface.St. Liebowitz's Cathedral.
The city had a remarkable population boom during the Boskone War, when many people who fled the "front lines" of the Main Belt took up residence there. This led to a housing shortage that was not eased until mid-2014, when the Fenspace Convention purchased surplus Irish housing, disassembled it, and shipped it to Port Lowell and other Fen cities.
Schiaparelli High School, located in downtown Port Lowell, is the largest secondary-education facility on Mars.
With St. Liebowitz's Cathedral located on the city's main square, Port Lowell is seen as a major religious center in Fenspace.
The main Interwave node for Mars is located at Port Lowell. It has sufficient capability to handle all of the traffic from Mars, Phobos, and Deimos, making it a backup system to the nodes at Phobos, Starbase 1, and Odyssey.
Operation Great Justice maintains a liaison office in Port Lowell.
Port Lowell is home to one of Mars' two Astroball teams, the Martian War Machine. They're noted for a particularly ruthless playbook (as befits their name).
