Avalon

Avalon is a luxury community in orbit around the Moon. It has about 100 permanent residents, and is sometimes referred to as "The most expensive place in the Solar System."

Description
Compared to most other orbiting space stations, Avalon is quite large. It has a capacity of 400 residents, and 400 staff. The station is ring shaped, with an inner diameter of 2 kilometers. The ring is 1 kilometer wide, giving Avalon a total land area of ~6.3 sq km (about 3 times the size of the Principality of Monaco). The ring rotates such that on the surface, there is an artificial gravity of 1g. Buildings on Avalon are no higher than about 50 feet, since anything taller would have insufficient artificial gravity at the top. The surface is covered by a large half-toroidal glass roof, which can be made opaque to simulate night and day. The roof operates on a 24 hour cycle, mimicking the day-night cycle on earth.

Spacecraft wishing to dock at Avalon must use one of two docking ports located at the center of the ring. There are two elevator shafts running from the center down to the surface used for moving people and supplies. Only two spacecraft can be docked to Avalon at a time.

There are large sliding counterweights on the underside of the ring, which can move to any point on the ring. These are used to evenly distribute weight on the station so that the rotation remains about a fixed axis. For example, if a significant number of residents are on one side of the station for an event, the counterweights could shift to the opposite side to keep the station balanced. The rotation is controlled by over 50 ion thrusters at the outer edge.

Avalon is powered via two redundant nuclear reactors, ensuring no interruption in power at any time.

Residences and Amenities
The station contains 300 apartment style luxury residences, and 100 residences with grass or rock lawns, of varying size. The residences range in size from 2,000 square feet to 20,000 square feet, and range in cost from $10 million to $800 million.

In addition, Avalon has:
 * 14 restaurants, including Two 3 Michelin star restaurants
 * A wellness center with a spa, swimming pool, gym, basketball and squash courts
 * A driving range
 * A 5 screen movie theater
 * A performing arts center/concert venue
 * A 50,000 square foot country club and banquet hall
 * Multiple places of worship, including two churches, two synagogues, a mosque, and a Buddhist temple
 * A state of the art medical facility
