The European Space Agency (ESA) has unveiled an ambitious conceptual design for a modular, sustainable moon base created by architecture firm Hassell. The inflatable habitat modules can house up to 4 astronauts and are designed to be 3D printed using lunar regolith.
Key Details of the Design
The conceptual design includes the following key details:
- Inflatable habitat modules: The base would consist of a series of interconnected inflatable pods made from lightweight materials that can be transported from Earth. Once set up, the pods are filled with air to create a pressurized 500 m2 internal area.
- 3D printed structure: An autonomous robot would gather lunar soil (regolith) to 3D print a protective shell around the inflated modules as well as structural components like tunnels to connect the pods.
- Sustainable systems: The base is designed to reuse materials, produce food, and recycle waste on-site using bio-remediation and autonomous robotic systems to create a closed-loop settlement. Solar panels would also provide renewable energy.
- Modular and scalable: The modular design allows the settlement to grow over time. Habitat pods and infrastructure like research labs can be added to support more crew members on longer-duration surface missions.
Path to Establish a Lunar Base
Establishing even a small-scale lunar base represents a monumental engineering challenge. Here are some of the key steps in the plan:
- 2025-2027: Launch missions to map the lunar surface in detail and scout potential base locations near the Moon’s south pole, which is thought to have water ice deposits.
- 2028-2032: Deliver a series of cargo landers with inflatable habitat modules, solar panels, communications systems, robotic systems for construction/maintenance, and other infrastructure.
- 2032: Launch the first crew of 4 astronauts to the lunar surface to set up the base. Astronauts would validate systems functionality and test capabilities like material harvesting and 3D printing in the lunar environment.
- 2034: Launch larger crews of up to 12 astronauts to live and work in the expanded base long-term. The modular design allows new inflatable pods, research labs, and other facilities to be added to support them.
Challenges and Next Steps
While modular and sustainable, the proposal remains conceptual and the lunar environment poses steep engineering hurdles:
-
Radiation and meteorites: The inflatable pods would need to be covered in sufficient lunar regolith shielding to protect inhabitants from galactic cosmic radiation, solar flares, and micrometeorite impacts.
-
Extreme temperatures: The surface temperature ranges from 126°C in sunlight to -173°C in shadow. Thermal management is critical to ensure vital systems can operate and the base is habitable.
-
Isolated environment: Missions would face risks like device failures, accidents, or medical issues without quick emergency backup from Earth, requiring extensive redundancy planning.
The concept builds on ESA’s planned Artemis Gateway lunar space station and aligns with the timeline for NASA’s Project Artemis lunar exploration plans. Next steps include further developing the modular habitat technologies and logistics models to assess feasibility for the 2032 initial base rollout target.
Hassell’s Vision of a Thriving Lunar Settlement
Hassell’s eye-catching renderings depict their ambitious vision of the lunar base growing into a thriving settlement supporting a population of dozens to hundreds:
- Domed crop growth chambers and fish farms provide food
- Laboratories, workshops, and dust-sealed factories enable research and ISRU production of water, fuel, and more from lunar resources
- Hard-shell inflatable living quarters with modular furniture house more residents in a comfortable environment
- A public square, garden dome, and communal spaces provide shared social areas
The regular transit of cargo and crew to the lunar gateway station orbiting overhead sustains continuous growth. The modular architecture means that if any single component fails, it can be repaired or replaced without compromising the entire settlement.
While the proposal remains firmly in the conceptual stage, the Hassell habitat design and supporting ESA mission architecture demonstrate the extensive planning and development underway to facilitate humanity’s permanent expansion into space through lunar colonization.
