Why Building a Mars Colony on Earth Could be More Practical

The idea of building a Mars colony on Earth may seem counterintuitive, but considering the vast expenses and harsh environmental conditions, it offers numerous advantages. From cost savings to realistic simulations of extraterrestrial environments, Earth-based models could serve as valuable stepping stones towards Mars colonization. This article explores the feasibility and benefits of constructing a Mars-like habitat on Earth and why it might be the pragmatic choice.

Feasibility of Earth-Base Mars Colonies

The concept of a Mars colony, strictly speaking, implies an environment indistinguishable from Mars itself. However, if such a colony were built on Earth, it wouldn't meet the stringent criteria set for Mars but would still offer unique benefits. The primary objective would be to create an enclosed, self-sustaining environment that mimics Martian conditions as closely as possible.

Enclosed Arcologies and Experimental Models

Some creativity in architecture and environmental science could facilitate the development of such an enclosed arcology. A notable example is the experiment conducted by biology students in Cornwall, England, who built a closed environment to study plant life under conditions similar to those expected in space or planetary colonies. This precedent demonstrates that creating a simulated Mars environment is feasible, albeit on a smaller scale.

Antarctic Research and Mars Simulations

Part of a 'Mars' base exists, albeit in a remote part of Earth. The personnel housing at the South Pole in Antarctica provides a controlled environment with conditions similar to Mars, such as daily temperatures and atmospheric water. However, this setup has limitations in terms of oxygen and nitrogen levels, which are significantly higher on Earth. To replicate the Martian environment accurately, the atmospheric pressure would need to be much higher, comparable to the summit of Mount Everest, and additional measures like solar filters might be necessary.

The Chilean Marta Mars Simulation

The Mars Desert Research Station in Utah, USA, and the ESA's Luna facility in Iceland serve as practical Earth-based models. These facilities simulate the Moon's environment, which, being even more challenging than Mars, are excellent contenders for testing habitats that might one day be deployed on Mars. These simulations provide invaluable insights into how humans and plants would fare in such extreme conditions.

Cost Savings and Resource Allocation

One of the most compelling arguments for Earth-based Mars colonies is the significant cost savings. Interstellar travel is incredibly expensive, not to mention the resource allocation and logistics required to sustain a colony on Mars. By building and testing the necessary equipment and infrastructure on Earth, the risk and cost are drastically reduced. Simulating Martian conditions on Earth allows for thorough testing of systems and protocols before any Martian mission.

Field Testing and Confidence Building

Before embarking on any Martian venture, every component would need to be field-tested to ensure reliability and efficiency. This process would involve extensive simulations and experiments on Earth, as well as on the Moon, which can be used as a proving ground between Earth and Mars. No one in the Martian colonization community would risk sending equipment without thorough testing. Therefore, a rigorous testing process on Earth and the Moon is a hallmark of a genuine Mars colonization effort.

Evaluation of Seriousness in Mars Colonization Plans

The current state of Mars colonization planning is largely theoretical and conceptual. As of early 2021, "bases" on Mars are more akin to "concept art" than functional habitats. To gauge the seriousness of such projects, one must look for evidence of field testing and simulations. Until these elements are present, any discussion of Mars colonies remains academic and speculative.

In conclusion, building a Mars colony on Earth could be a more practical and cost-effective approach. From experimental arcologies to lunar simulations, there are many aspects of Mars colonization that can and should be tested on our planet. This strategy not only saves resources but also ensures the reliability and safety of any Mars mission that follows.
