Chaos in space: Is 22 calm people enough to occupy Mars?
Compared to previous calculations, which estimated 100 to 500 people as the minimum number of people a self-sustaining colony on Mars could be effective, according to a new study, even a fraction of that number is sufficient for the task. However, it does not matter what mental make-up the first inhabitants of the Red Planet possessed, and how they reacted to stressful situations.
Twenty astronauts are enough to build and maintain a Martian colony
According to a new study, it claims that this low number, compared to previous estimates of at least a hundred people, could sustain a colony on the Red Planet. The researchers, including colleagues from George Mason University in the US, reviewed previous studies that estimated that 100 to 500 astronauts would be needed to establish a self-sustaining Martian colony. The preliminary results of their new analysis, which are still awaiting review, have been published on arXiv, according to The Independent.
The authors of the study, which is posted on a site that provides free access to, among other things, scientific publications in physics, mathematics and computer science, took into account human social and psychological behavior and the continuity of interactions between people to create the new estimate. .
According to the results, only 22 people could be enough to build and maintain a space colony on Mars. And based on decades of research, the global space agencies have proven it
Establishing any human settlement on Mars would be an incredibly complex engineering problem.
According to scientists, the inhospitable nature of the Red Planet requires, among other things, that The housing built there must be largely self-sufficient. Aside from extracting some essential minerals and water, future Martians will depend partly on terrestrial supplies and partly on local replenishment for their needs.
In the new study, the researchers sought to better understand the behavioral and psychological interactions of future Martian settlers. “We aim to identify areas that need to be considered in colony planning, as well as to suggest a minimum initial population size needed to establish a stable colony.” They wrote in the study.
For analysis, earlier scholars
Data was analyzed About high-performance teams operating in isolated, high-pressure environments, such as submarines, Arctic Research, and the International Space Station,
To model interactions between participants. The scientists used a type of computer simulation called agent-based modeling (ABM) for modeling. ABM takes into account simple rules and behaviors.
The researchers used the model to simulate the survival of a human settlement on Mars under various operating conditions, including when global events such as accidents or delays in supplies from Earth affect the colony.

Scientists created models of Martian settlers that examined various factors on an individual level such as metabolism, resilience, skill and stress levels, and four psychosocial traits – neurological, reactive, social, or agreeable.
Among other things, the researchers came to the conclusion that
The “nice” personality type associated with greater empathy was generally the type that was most likely to survive.
While those with a “neurotic” psychological makeup died at a much higher rate independent.
