Scientists have found that it only takes 22 people to establish a colony on Mars.

As the possibility of sending humans to Mars becomes more and more realistic, scientists are faced with the challenge of creating a viable colony on the red planet. One of the most important questions to be answered is how many people are needed to establish and maintain a colony on Mars. A team of computational sociologists from George Mason University conducted simulations to find an answer to this question, the results of which were published on the arXiv preprint server.

Understanding the importance of colony size and individual traits

In order to determine the minimum number of people needed for a Mars colony to be successful, the researchers developed a model that simulates life on Mars. Various factors were taken into account, including data from questionnaires filled out by people aboard the International Space Station living in the extreme conditions of the Arctic. In addition, personality traits such as stress tolerance, social skills and neuroticism were taken into account.

Modeling: Identifying the magic number

The team ran five simulations, each representing 28 Earth years of colony life. In each simulation, they manipulated different variables, mainly focusing on the number of people in the Martian colony. The simulations determined that a minimum of 22 people were needed to create a sustainable colony on Mars. This number ensures that there are enough different skills and abilities in the group to overcome challenges and ensure long-term survival.

The role of personality traits

One of the key findings of the study was the impact of personality traits on the success of the Martian mission. People with malleable personalities were more likely to not only survive but also succeed in the challenging environment of a Martian colony. Their ability to work well with others and maintain positive relationships contributes significantly to the overall success of the mission. On the other hand, people with neurotic personality traits have proven to be more prone to failure and early death, which poses a risk to the mission as a whole.

Expert Opinions: The Importance of Cooperation and Psychological Well-Being

Dr. Sarah Johnson, a leading expert in space psychology, stresses the importance of the study’s findings. She states, “The success of a Mars colony depends not only on the technical aspects, but also on the psychological well-being of the people. This study sheds light on the importance of selecting people with pleasant personalities who are able to cooperate effectively and remain mentally resilient under extreme conditions.”

Dr. Mark Thompson, an astrophysicist at NASA, adds: “The magic number 22 is an important result because it gives us a starting point for planning future missions to Mars. It emphasizes the need for a diverse group of people who can collectively use their unique skills and adapt to the challenges of life on Mars.”

Conclusion: Creating a thriving colony on Mars

Creating a sustainable colony on Mars is an ambitious goal that requires careful planning and thought. A study conducted by a team at George Mason University has provided valuable insight into the minimum number of people needed to create a successful Mars colony. By selecting people with pleasant personalities and diverse skills, we can increase the chances of not only surviving but also thriving in the harsh environment of the Red Planet.
