Production
Production spaces and facilities for a Mars settlement may occupy a large part of the available space in a colony. Production facilities including Agricultural, Manufacturing, Mineral extraction, Craft production and even, eventually, Entertainment production will be the main users of energy on Mars. Propellant production and agricultural production in particular.

Agricultural production and facilities
Until terraforming or genetic manipulation provides the possibility of plant production outside of an artificial environment, agriculture will require greenhouses, either naturally or artificially illuminated. Agricultural production will also include hydroponics, aquaponics, aeroponics and possibly animal husbandry.
Entertainment production and facilities
Mars will need a radio and a TV station. Locally produced shows will be in demand as soon as they are possible.
Manufacturing production and facilities
Manufacturing on Mars will be similar to manufacturing on Earth. However, there will be no heritage infrastructure that needs to be preserved or supported. The most modern techniques such as 3D additive manufacturing may be used extensively.
Heat recovery, rather than burning hydrocarbons, will be used as much as possible for heating and most heating processes will be electrical. Steel, glass, ceramics, concrete and aluminium may be primary products. All manner of manufactured goods, equipment, clothing, utensils and containers will be manufactured as equipment is imported or built on site and speciality manufacturing comes on line.
Mineral and water extraction facilities
Mining will require facilities in addition to the mines themselves. Crushing equipment, garages, stores and laboratories will be required on site. Loading stations and transportation equipment will also be required.
Atmospheric extraction facilities
As an element of propellant production and as a source for most of the carbon and atmosphere for the colony, atmospheric production is an important part of a settlement production facilities. The first stages of atmospheric treatment may be exterior, to profit from the cooling available from the cold martian outdoors. Fans, compressors and coolers will dissipate large amounts of heat.
Propellant production facilities
In the early days of the martian settlement propellant production will be one of the main thrusts of development. IN-situ resource utilisation is an obligation if the transportation costs are to be at a level that can make the settlement possible. Eventually, as the ratio of settlers to immigrants goes up, the amount of locally produced goods goes up and the required importations go down, propellant production will become less central to the settlement economy.
Electrolysis of water is the basis of all the propellant production schemes. In particular now that it has been discovered that there are large quantities of water on Mars.
