The Phobos Campus

Starfleet Academy maintains a training center on one of Mars' two moons to train cadets in low-gravity and extravehicular operations. Phobos is a small, irregular, Class D planetoid, only about 30 kilometers in diameter. A large crater - Stickney - running nearly half the moon's length, mars its surface. Stickney Crater hosts the Academy's Phobos Campus, also known as Stickney Campus.

The campus consists of a series of pressure domes connected by tunnels, all made of tinted transparent aluminum specially shielded against solar radiation, affording a clear view of the crater's surface outside. Each dome has variable artificial gravity, allowing cadets to study in a variety of gravitational conditions.

The Phobos campus primarily allows cadets to train in microgravity and low-gravity environments. Although Starfleet vessels are equipped with artificial gravity generators, personnel are expected to be able to operate under variable gravity conditions. Cadets train to use pressure and environmental suits in different settings, both inside and outside the campus facilities. Part of environmental suit training consists of hiking across the entire diameter of Stickney Crater.

Cadets also train in extravehicular activity at the Phobos campus: learning to use magnetic grapplers to walk on the exterior of a ship or station's hull, using thruster packs to maneuver in microgravity environments, manipulating equipment and tools inside an environment suit, and related skills.

The Phobos campus provides living quarters for staff and faculty on duty there, and for cadets on extended training missions. The station does not contain docking facilities for starships, but maintains a hanger bay for shuttlecraft and several transporter stations (both personnel and cargo). Cadets often arrive at the station aboard shuttlecraft so they can appreciate the surface of Phobos from a distance; they're likely to see a lot of it during their training.
