Researchers at the University of Bordeaux (Bordeaux Institute of Technology) have created a mathematical model to calculate the number of people who are enough to colonize Mars.
The model is based on the ratio of the time required to achieve certain indicators that ensure long-term survival (oxygen production, food production, water supply, etc.), to the life time of the first settlers themselves. The model also takes into account an important variable: if an action can be performed by several people, then it reduces the time to achieve a specific goal.
As it turned out, for the successful colonization of Mars, a large number of people are not needed – 110 people will be enough. According to scientists, such a number of people is enough to enable them to develop agriculture and industry, as well as devise ways to collect, store and distribute resources.
