The Future of Human Settlements on Mars and the Moon

Long a dream of the imagination of man has been living somewhere in the solar system aside from Earth, and with Mars and the Moon being the leading contenders for future homes. Thanks to advances in space exploration these dreams are now no longer as science fiction as they once were, but possibility. However, today, we’re seeing very serious conversations, serious research, and serious projects that are going to make human settlement on Mars or the Moon feasible, or at least explainable within our lifetimes. What would life be like on these far away worlds, then? In this post, I want to talk about the challenges that come with the research on extraterrestrial living, as well as the opportunities and the potential innovative technologies that we can develop to transition to extraterrestrial living.

Why Mars and the Moon?

Our closest neighbor in space, the Moon, has already come in handy as a stepping stone to space for mankind. The ease to which humanity could settle off world undoubtedly makes the Moon a relatively ‘easier’ site. Mars, though much farther away, is especially tempting because it looks like Earth, with polar ice caps, seasons, and even evidence of ancient rivers. Establishing human settlements on either celestial body could also bring invaluable benefits: from new scientific discoveries, new mining opportunities, and, in some cases, as ‘backup’ sites for preserving of human civilization.

Extraterrestrial Settlements – Major Challenges

1. Extreme Environments

Many environmental challenges await Martian and Lunar Life. Both places have no thick atmosphere or a magnetic field to protect us from solar and cosmic radiation. Temperatures on the Moon also fluctuate between scorching heat during the lunar day and nightmarish cold during the lunar night, and on Mars everything is bone cold with a mean surface temperature of about -80° F (-60°C).

2. Lack of Resources

Like Mars and the Moon, what both planets have in common is water ice, but none of them have breathable air, food, or enough building materials. Growing food, making breathable air, and building structures that won't collapse involve (often) developing the ability to isolate the ability to grow food and provide breathable air, and to build sustainable structures using often locally sourced material not possible to transport from Earth.

3. Impact on Psychology and Social Situation

Social and psychological challenges will come, of course, living millions of miles from Earth for extended periods. International Space Station astronauts can communicate with Earth, but if the communication is with Mars, for instance, delay of up to 24 minutes each way will impact even the most rudimentary interchange. It will be important to mental resilience, community building, and entertainment tools to keep future settlers healthy and motivated.

Settlements with innovative approaches to enable settlements.

1. Habitat Engineering

And for each celestial environment, advanced habitat designs, from SpaceX's Starship concept to NASA's inflatable habitats to the European Space Agency's 3D printed lunar base plans, are being engineered to withstand each situation. Habitats on Mars will also have to filter out harmful dust, and pressurize. Similar to the Moon, 3D printed structures built from lunar regolith (lunar soil) will reduce dependency on transporting building material from Earth.

2. Resource Extraction and ISRU

The ISRU technologies will permit settlers to use locally available materials. So the Moon’s regolith will be potentially buildable and the lunar poles and Martian soil can be processed into water for drinking, agriculture, and to provide breathable oxygen. Also, carbon dioxide exists on Mars, which can undergo advanced chemical processes with advanced chemical processes to turn it into useful fuel and compound.

3. Agriculture and Life Support

Long-term missions will require the growth of food in space. Scientists are trying to figure out how to grow crops with Martian and lunar soil plus nutrients. On Mars and the Moon, closed-loop systems will be created with hydroponic systems that use a water-based nutrient solution and bioreactors to recycle human waste into fertilizers and oxygen.

4. Energy Solutions

I think solar energy is a promising addition to lunar and Martian colonies. In places of continuous sunlight, like the poles, their solar panels could be located on the Moon for continuous power. Because Mars is further from the Sun, therefore having less solar energy, and is also subject to frequent dust storms, nuclear power may be needed to supply a continuous energy source.

Vision for the Future:

How Might Daily Life Be?

Imagine waking up on Mars. Inside your dome you live, shielded from cosmic radiation, breathing a breathable atmosphere, with your temperatures regulated by modern climate control. You may even begin mining operations on-site or work on studies exploring Martian geology in a research facility after breakfast. Activities such as virtual reality appearances of Earth or even gathering with others settlers for small community strivings could comprise free time.

Final Thoughts:

A New Era for Humanity
However, the trip to making human settlements on Mars and the Moon is only just commencing. Plans will be underway to turn distant worlds into livable spaces from agencies like NASA, private enterprises such as SpaceX, and many others who are taking their first concrete steps. These will be settlements running on human ingenuity and adaptability, forcing a spirit of pioneers similar to the great explorers of history.
