Minimum Size of a Self-Sufficient Mars Colony - Overcoming Technological and Industrial Challenges

When contemplating the establishment of a self-sufficient colony on Mars, the prevailing thought might be to consider the maximum size. However, as discussed in this piece, the query to focus on is the minimum size - and it is, intriguingly, quite substantial!

The Complexity of Self-Sufficiency

To thrive on Mars, a colony must be entirely self-sufficient. This requires an array of crucial infrastructure, from basic living essentials to complex technological systems. Just like on Earth, where even the most rudimentary technological capabilities suffice to sustain life, Mars presents an environment that necessitates high-level technology to support human life.

Technological and Industrial Capabilities

A Mars colony must be able to generate its own power, seamlessly supply materials, produce food, and manufacture medicines and pharmaceutical chemicals. Without these, survival becomes impossible, evident in the unforgiving and hostile conditions faced on Mars.

Thrusting this back in time, perhaps a less advanced technology approach could be applied. For example, instead of the cutting-edge electronics and medicines available today, a 1990s-grade alternative might suffice. However, this still implies the need for breathable air, water, radiation shielding, and sustenance, which mandates an extensive and intricate supply chain.

Bootstrap and Supply Chains

The challenge is daunting: bootstrapping an entire civilization on Mars with no reliance on Earth is a monumental task. However, the number of inhabitants required may seem somewhat manageable, with the need for construction workers, support staff, and individuals engaged in research and development (RD). Much of the knowledge work could be undertaken on Earth, but the people on-site must have the necessary resources and supplies.

The logistical challenge, however, is insurmountable given current transportation costs. Transporting goods to Mars currently costs an estimated 2 million per kilogram. Assuming this can be reduced by 90% still makes the endeavor incredibly expensive. Achieving full functionality and self-sufficiency is estimated to take centuries, if ever.

Investment and Self-Sufficiency

Considering the time and cost invested, financing such an endeavor through traditional stakeholders is impractical. Banks and investors would likely dismiss any proposal with a return on investment (ROI) measured in centuries, let alone a 200 trillion loan. This underscores the non-viability of such a project in terms of financial and logistical feasibility.

In conclusion, while the idea of a self-sufficient Mars colony is theoretically possible, the practical execution demands substantial planning, investment, and innovation. The minimum size, as highlighted, is vast, involving an intricate web of technological and industrial capabilities that cannot be reduced without compromising the long-term viability of the colony.
