How Many Humans Are Needed To Build A Colony On Mars? Scientists Say Only...
Mars is the most promising destination for human exploration and colonization in the solar system. But how many people would it take to establish a self-sustaining settlement on the Red Planet? Scientists have recently revealed the surprising answer: only 22.
The Challenge of Colonizing Mars
Building a human colony on Mars is not an easy task. It requires overcoming many engineering, scientific, and logistical challenges, such as:
- Launching and landing heavy payloads of equipment, materials, and supplies on the Martian surface
- Providing adequate power, water, food, oxygen, and shelter for the colonists
- Protecting the colonists from the harsh environment, such as radiation, dust storms, and extreme temperatures
- Ensuring the health and well-being of the colonists, both physically and mentally
- Developing the infrastructure and technology to support scientific research, exploration, and industrial activities
- Maintaining communication and cooperation with Earth and other potential colonies
Moreover, any colony on Mars would have to be largely self-sufficient, as resupply missions from Earth would be costly, infrequent, and risky. Therefore, the colonists would have to rely on local resources, such as water ice, regolith, and atmospheric gases, to produce what they need. They would also have to be able to repair and replace their equipment and systems, as well as reproduce and educate new generations of colonists.
The Minimum Number of Colonists
Previous estimates of the minimum number of colonists needed to build and sustain a Mars colony ranged from 100 to 500 people. These estimates were based on factors such as genetic diversity, social stability, economic viability, and technological development.
However, a new study by computational social scientists at George Mason University suggests that a much smaller number of colonists may be sufficient: only 22. The study used a computer simulation called Agent-Based Modeling to predict the survival of a human habitat on Mars under various conditions. The simulation considered individual factors such as metabolism, resilience, skills, and stress levels, as well as four different psychological profiles: agreeable, conscientious, neurotic, and open.
The simulation showed that an initial population of 22 would be the minimum required to maintain a viable colony size over the long run. Additionally, the study found that individuals with an agreeable personality type were more likely to survive, while those with a neurotic personality type had a higher mortality rate.
The researchers explained that their finding challenges the conventional wisdom that larger populations are more resilient and adaptable. They argued that smaller populations may have some advantages, such as lower resource consumption, easier coordination, and stronger cohesion.
The Implications for Future Mars Missions
The study has some implications for future Mars missions and colonization plans. It suggests that sending fewer people to Mars may be more feasible and efficient than sending hundreds or thousands. It also suggests that selecting the right people for the mission may be more important than selecting a large number of people.
However, the study also has some limitations and assumptions that need to be considered. For example:
- The study did not account for external factors such as natural disasters, accidents, or conflicts that may affect the survival of the colony
- The study did not account for cultural, ethical, or political diversity among the colonists or their interactions with other colonies or Earth
- The study did not account for the effects of long-term isolation or adaptation to the Martian environment on the colonists' psychology or physiology
- The study did not account for the possibility of technological breakthroughs or innovations that may enhance or disrupt the colony's development
Therefore, more research and experimentation are needed to validate and refine the study's findings and recommendations.
Conclusion
Mars is a fascinating and challenging destination for human exploration and colonization. Scientists have recently estimated that only 22 people may be enough to build and sustain a colony on Mars. This finding may have some benefits and drawbacks for future Mars missions and plans. However, more research and testing are needed to confirm and improve this estimate.

FAQ's
How many people would we need to colonize Mars?
Using math and Mars Society estimates, a computer scientist says a Mars colony needs 110 people to survive. Elon Musk's high-profile Starship has ambitions to help people reach and settle Mars.
How many people would we send to Mars?
The answer, according to a paper published in Scientific Reports, is about 110 people. The number of people that could be sent to another planet would be rather limited, says Jean-Marc Salotti at the Bordeaux Institut National Polytechnique, the author of “The Minimum Number of Settlers for Survival on Another Planet.”
When can we colonize Mars?
Serkan Saydam, deputy director of the Australian Centre for Space Engineering Research and a professor at the University of New South Wales in Sydney, said human colonization of Mars is possible within decades. "I believe by 2050 we will have a human colony on Mars," Saydam told Live Science.
