How many humans are enough to form a colony on Mars?

Found a colony in Mars over time may not require as many people as scientists think. A new study presented by George Mason University, in the United States, ensures that a human settlement will be successful if it is made up of 22 people, as long as they have specific personalities.

Through a computer simulation, a team of researchers determined what would be the minimum condition for a stable research outpost on Mars to be successful. Although self-sufficiency is the ultimate goal , the article clarifies that it must ass Phone Number List ume total dependence on the delivery of supplies to the Earth. The first humans on Mars will live between supply missions while studying Martian resources and dealing with limited technology.

While techniques are developed to make humans independent on Mars, attention must be channeled into the interactions of the members of the mission. Catastrophic colony failures could occur from one day of stress. For the scientists who made the report, the stress on Martian soil would only be comparable to that generated by equipment inside submarines, base camps in the Arctic, and even missions in the middle of a war.

Personality is the key, according to the MARS-COLONY model
The scientists used as a basis the computational model that projects the evolution of the members of a stressful mission on Earth and added space components. The final model is called MARS-COLONY. In this simulation, Martian colonists interacted with each other for years as they produced and consumed resources. . The more time passed and the problems became present, the more his mental health was affected.

To measure teamwork success, the model considered four basic personality assumptions. Based on them and their assigned values, the final result of the simulation changed. The study clarified the presence of the following labels:



Pleasant: individuals with the lowest degree of competitiveness, low aggressiveness and without a fixation on strict routine.
Social: individuals with a medium degree of competitiveness, extroverts, who require social interaction, but are not obsessed with strict routines.
Reactive: with a medium degree of competitiveness, competitive interpersonal orientation and obsessed with strict routines.
Neurotics: with a high degree of competitiveness, very aggressive interpersonal characteristics and a capacity to adapt to boredom or a questionable change in routine.
The MARS-COLONY showed that, for a colony of 28 Terran years, the minimum number of inhabitants that must exist is 22. The model also mentioned that filling the colony with people with low aggression and less anchored to routine (Pleasant) were the subjects who ensured the success of an advanced research position for decades. On the contrary, aggressive individuals with little adaptability to change (Neurotic) represent a drastic decrease in the colony's survival probabilities. In all simulations, groups were able to recover and continue with the mission until a rescue if their population remained at a minimum of 10 people.
