The Habitat has different propulsion systems which can be classified according to their range.

Inter-planetary propulsion

AYSE Drive

See AYSE Drive for main article.

The Habitat is propelled through interplanetary space by the AYSE Drive. The AYSE drive functions by projecting gravitons in front of the Habitat. These particles interact to produce a singularity which draws the Habitat forwards. Since it is an artificial singularity, it quickly vanishes before the Habitat comes close enough to be damaged by the gravitational pull.

Plasma Drives

An alternative method of propulsion which is being considered to replace the AYSE Drive is a more conventional propellent-based drive system. It would move by emitting a propellent at high velocities from the rear of the Habitat. The current proposal is for a magnetoplasmadynamic thruster. This thruster works by taking the plasma from the fusion reactor and accelerating it with a magnetic field. The strength and shape of this magnetic field is manipulated to control the speed and direction of the exhaust gases. For additional thrust, carbon dioxide from the Life Support systems can be ionized and fed into the exhaust stream, providing more thrust.


See SLINCE Drive for main article.

The SLINCE drive, short for Super Long Inducting Navigational Coil Emergency Drive, is used in the event that the AYSE Drive fails. The SLINCE Drive works by deploying a long superconducting cable into a coil. A strong voltage is then passed down the cable, producing a magnetic field to launch the Habitat back towards Earth.

Short-range propulsion

Habitat Engines

The Habitat's main propulsion when detached from the AYSE drive is provided by four ion engines, powered by the Habitat reactor. They offer both positive and negative thrust, allowing a certain economy of movement.

Maneuvering Thrusters

Once detached from the AYSE Drive, the Habitat uses a series of pulsed inductive thrusters to navigate into a descent trajectory and to rendezvous with the AYSE drive for its return trip. These thrusters use electricity to ionize and propel gas at high speeds. They are powered by a bank of capacitors and are thus suited to deliver short bursts of power.
