Foundation of an Autonomous Colony
The Foundation of an Autonomous Colony on another cosmic body is one of the most challenging tasks for humanity. Though it requires enormous effort, the goal to expand the influence of mankind throughout the Solar system is worthwhile. This motivation has several aspects. This page covers general issues of an autonomous colony on Mars.
What is an autonomous colony? The main attribute is independence from Earth. Once the colony is set up, it provides a habitat for settlers on the long run, hopefully forever. The second attribute is a planned and indefinitely stable colony that can thrive from local resources. Unlike a mission with planned death the settlers in an autonomous colony have a future for themselves and for their Mars-born children. The ultimate expression of independence from Earth may be the complete political independence of a colony.
The transport of colonists from Earth to Mars is a very complicated part of the plan. There are many threats inherent to space travel: Solar & Cosmic Radiation, Meteorites, Physical & Mental Illness, etc. Plans will need to be made to deal with every possible problem.
Since people can not live in the natural environment a basic artificial habitat with houses, supplies and equipment for a long term stay would be deposited on Mars' surface. The equipment must be technologically sufficient to allow the colonists to grow their own food, build new houses, etc.
There are many uncertainties about the impact of the Martian environment. The equipment would be tested on Earth thoroughly, but the influence of the Martian environment cannot be understood completely on Earth. The safest way is an unmanned setup of a whole settlement by an automated and remote controlled machinery.
Energy is the most critical resource. It is needed for lighting and heating of greenhouses, for metallurgy and production of machines. The critical path is the generation of enough energy for the production of spare parts for the energy generating systems and greenhouses. In other words: If the energy generating systems and greenhouses can not be maintained endlessly with the amount of energy they produce, an autonomous colony is not feasible.
The available solar energy on Mars is slightly less than have the one available on Earth for the same area. An analysis of the embodied energy in solar panels fabricated on Mars would need to be done to prove that the panels can generate more energy than they use for their construction and operation. The embodied energy of polycristalline solar cells is about 4000 MJ/km2. For a system that masses 3 kg/m2, the embodied energy would be 12 000 MJ/m2. A solar panel on Mars should produce about 3,6 MJ/day. So the cell would produce the energy for it's own fabrication in about 3300 days, or about 9 years. So the rest of the energy produced during the cells lifetime can go to other uses, and it should be possible to create a self sufficient settlement.
The preparation cost for a mission like this is tremendous. A financial effort estimation helps to get an overview.
Within a small group of colonists, a daily council of all members may be sufficient to address the needs of governance, much in the tradition of the New England town hall meetings. In a growing community some kind of representative democracy will become necessary, although this type of government may not be well suited to a small colony in a hostile environment.
Independence doesn't imply isolation. Mars can have independent settlements that are not isolated, have regular increases of their population through immigration and trade with Earth in the financial spheres and information spheres, even if they are independent physically.
Before heading for Mars any crew is quarantined to ensure they do not suffer from infectious diseases. As a result, the Martian colony should be more or less free from pathogenic germs, which saves medical effort. However, for children born on Mars an even more effective vaccination program will be necessary to stimulate the development of Mars-born immune systems.
The size of the human population must not be too small due to the risk of inbreeding depression. This can be positively influenced through the use of in-vitro fertilisation from genetic stock for the first child born to every colonial family. Alternatively, immigration should provide variations to the genetic stock. Unless Earth is lost, immigration should always be available.
Increased exposure to radiation may increase the incidence of cancer. Colonists will need shielding from radiation during transport from Earth to Mars and on Mars' surface, due to the thin atmosphere and lack of a planetary magnetosphere.
Compared with Earth the limited industrial performance of an autonomous colony does not allow the same level of medical care. High sophisticated accessories for surgery and a great variety of drugs are impossible to produce. Alternatives to standard medicine considered taboo on Earth may be forced upon the growing settlement, such as the use of genetically altered pig organs in emergency transplants.

- What skills and technologies are needed to have a small self-sufficient economy rather than a 8-billion-person global economy with its highly interdependent and very specialized jobs and technologies?
