Habitat Systems refers to all of the components of the Habitat which are critical to its functioning including the Habitat itself. The development of high-quality systems is one of the OCESS's main objectives, and their maintenance is critical to the well-being of the astronauts during the mission.

The current Habitat configuration is the Hawking III.

Habitat Systems as described here and in all associated articles are considered to be in the Beta reality. Thus, while an article may describe the fusion reactors employed in the AYSE drive, it is understood that Spacesim does not actually possess this technology, and that these are merely simulated for the purposes of the mission.

Communication Systems

Main article: Communications Systems

The Habitat uses both radio, laser, and IEST communications systems in order to maintain contact with Mission Control and transmit data back to Earth.

The radio system uses amplitude modulation, and is the primary method of voice communication.
The laser system is used to transmit text-based data and computer files to the SIMSAT communications satellite in Earth orbit.
The IEST is an experimental device based on the spin dynamics of electrons that is being developed to replace the Laser system.

Engineering Systems

Main article: Engineering Systems
Engineering Systems refers to the electronic and mechanical systems of the Habitat including Energy Generation and Propulsion, but excluding mechanisms used in Environmental Systems. Engineering Systems are monitored on the Power Grid software according to the Engineering Procedures.
The Power Grid software: used to monitor the Engineering Systems.

Without power to Life Support, the Vents and Water Recycler will not operate.

Environmental Systems

Main article: Environmental Systems

The Environmental Systems provide or control atmospheric pressure, fire detection and suppression, oxygen levels, waste management, and water supply. The Habitat is not an environmentally closed system.

High-powered fans move gasses in and out of modules
Atmospheric Filters
Various filters to scrub Dust, C02, and Humidity
Water Recycler
Low-efficiency water reclamation unit
Fire Suppression
Smoke Detectors and Extinguishers
Waste Management
Chemical Toilets (no water is reclaimed)

Hull & Superstructure

Latest drawing of the Hab, in its launching configuration, made by Chen-tao LaRochelle.
Main article: Category:Hull & Superstructure

Hull and Superstructure refers to the overall physical design of the Habitat: its shape, subdivisions, and composition.


In outer shape, the Hawking III can be described as a rectangular prism of various modules tied together by a binding structure. A hemispherical dome is on the top and a metal strut sticks out near its center. A somewhat hemispherical heat-shield dome for re-entry is on the bottom. To each corner of the prism are protruding triangular shapes, pointing downwards, hosting the set of four positive-thrust ion engines and the landing gear. This configuration of the Habitat is depicted in the works of Spacesim artist Chen-tao LaRochelle.


The interior of the Habitat is divided into three sections and two decks. The Pressurized Deck hosts the Hab Section and is where the astronauts live during the mission. The Unpressurized Deck contains the Engineering Section and the Storage Section, both inaccessible by the astronauts during the mission.

Pressurized Deck

Main article: Pressurized Deck

The Pressurized deck is the Hab itself (Hab Section for organizational purposes) and it is located at the bottom of the superstructure. It is divided into seven modules, each with its own bulkhead and environmental controls. These modules are the Airlock, the Bathroom, Command and Control, the Engineering Closet, the Hotlab, the Interlock, and the Longhouse. Oxygen and Gravity are conveniently available in the Hab Section.

Unpressurized Deck

Main article: Unpressurized Deck

The Unpressurized Deck of the Hawking III is located above the Hab and contains the Engineering Section and the Storage Section. The reactor, life support systems (Oxygen reserves, air scrubbers, etc..), AYSE docking, SRB clamps and EM-field generator form a quasi-deck in the Engineering Section. Just above are assembled the 4 water tanks and the ring of 10 compressed Hydrogen fuel tanks of the Storage Section, forming a rudimentary shield against certain radiations. It is inaccessible to the astronauts, but all controls are inside the Pressurized Deck, except for the emergency manual overrides (standard manual overrides are located in the Engineering Closet).


Main article: Hull Plating

The Habitat is protected by a series of ablative armour plates. These plates are laminated and spaced away from the Habitat, forming what is known as an "ablative spaced-laminate". It is a combination of several techniques used to protect tanks and other armoured fighting vehicles.

Wiki Project

Main article: Category:Habitat Systems

Habitat Systems are the subject of a major wiki project, initiated by Alex Foo in 2006-07. The project seeks to define all of the systems used at Spacesim whereas the true definition of the technologies employed is often nebulous and fudged over with references to physics classes and science fiction. The project is ongoing as of April 2010.
