Quick takeaways
Establishing a viable economy on Mars faces significant economic challenges and may not be justified without tangible economic advantages.
Gaining access to unlimited resources in space could revolutionize economics, but current technology and cost constraints hinder resource harvesting.

The Economic Viability of Space Settlements
Setting up permanent settlements on celestial bodies like the moon and Mars face economic challenges. While there is no scarcity of technology to reach these locations, the lack of economic incentives hinders their exploration. Even though the technology has improved, since the moon landing, it has been over 50 years since humans have visited the moon. The cost of a mission to Mars is significantly higher and requires immense resources but lacks economic justification. Bragging rights and proving capability remain potential motivators for governments or private companies to invest in a Mars mission. However, establishing a permanent settlement in space or on Mars requires long-term economic viability. Without tangible economic advantages, such settlements might be nothing more than impressive science demonstrations.
Accessing Unlimited Resources in Space
One potential economic advantage of space exploration is gaining access to unlimited resources. With billions of dollars worth of materials available in asteroids, space could provide humanity with a near-infinite supply of resources, altering the fundamental nature of economics itself. However, harvesting these resources at a cost that makes economic sense is beyond current technology. Moreover, the projected growth of human population and energy demand suggests that space colonization could offer a solution to resource limitations on Earth. Expanding into space would allow for large-scale energy harvesting and provide more room for population growth. Developing the infrastructure to make space industry and energy collection commercially viable is a goal pursued by companies like Blue Origin.
Challenges and Motivations for Permanent Space Settlements
The challenges of establishing permanent colonies in space go beyond economics. Space colonization could provide humanity with a backup plan in case of catastrophic events on Earth. However, the cost of building a colony on Mars or creating artificial gravity in space stations like O'Neill cylinders is currently prohibitively high. While these endeavors have scientific, philosophical, and existential value, they require significant resources that could be allocated elsewhere to address more immediate threats on Earth. As technology improves and costs decrease, the potential for long-term space settlements to add value to human civilization increases, making them a viable investment in the future.
With billionaires like Elon Musk and Jeff Bezos setting their sights on space exploration and development, there must be some commercially viable industries in space and on Mars, right? Well, it's a little more complicated than just mining the asteroids that contain trillions of dollars of value, or building heavy things in micro-gravity, and certainly a base on Mars might cost more than it's worth. Making Mars a viable economy might not even be possible.
