Building Tall on Mars: Practicalities and Challenges

The red planet, Mars, presents unique challenges when it comes to constructing buildings, especially when it comes to height. The reasons for building tall on Earth, such as scarcity of land in high-demand areas and the desire to create landmarks, may not apply to Mars in the same way. This article explores the practicalities and potential challenges of building tall on Mars, with a focus on surface and subsurface structures.

Protection from Radiation

One of the most significant concerns in building tall structures on Mars is dealing with the radiation present on the planet's surface. Radiation can penetrate the surface and pose health risks to the inhabitants. Subsurface structures are likely to be more practical in providing protection from radiation. These underground structures can be built beneath the Martian surface to shield individuals from harmful radiation. They can serve as living quarters, workspaces, and storage facilities.

White Towers for Communication and Dust Mitigation

However, surface structures may still be necessary for communications and dust mitigation. Taller towers, up to 20 to 40 feet high, can serve multiple purposes. These towers can act as communication beacons for Mars missions and as dust mitigation structures. The towers can be designed to be highly visible, perhaps painted white and equipped with blinking red lights. These towers can provide a recognizable landmark for Mars proximals (early settlers) to find their underground habitations. Additionally, the towers can be fitted with solar panels, providing necessary power for the structures below.

Visible Orientation for Martian Dwellers

For the early inhabitants of Mars, having a visible orientation point is crucial. The habitat entrance, located underground, may be difficult to locate in the vast Martian landscape. Consequently, a tall tower could serve as a prominent landmark, helping individuals identify their exact entrance. The towers can be designed to glow or blink, making them easier to spot in the dark. This is particularly important during dusty nights when visibility might be limited.

Dust Mitigation and Navigation Challenges

Dust is a major concern on Mars. The planet is known for its frequent dust storms, which can make it challenging to navigate and find specific locations. Even with the dramatic SpaceX Starship looming in the distance, which can be a recognizable landmark, dust storms can still pose significant challenges. To mitigate these issues, additional electronic beacons can be installed in rovers and spacesuits for extended missions. These beacons can help provide real-time navigation and location data, even in dusty conditions.

Mars Infrastructure and Future Prospects

The practicality of building tall structures gradually shift as Mars infrastructure develops. At the initial stages, practical considerations such as cost and materials availability will likely dominate. Underground construction is more viable in the early stages, reducing the exposure to harmful radiation and other environmental risks. As the infrastructure develops, there may be opportunities to construct taller above-ground structures, creating landmarks and utilizing land more efficiently. However, this will depend on advancements in materials science and construction technology.

Final Thoughts

Building tall on Mars presents unique challenges and opportunities. While radiation protection, practicality, and physical constraints will guide the design of structures, the ultimate goal will be to create a thriving, sustainable community. As we continue to explore and colonize Mars, the balance between above-ground and subsurface construction will evolve, shaped by technological advancements and the needs of the growing Mars community.
