"Humanity will not remain on Earth forever, but in its pursuit of light and space will first timidly venture beyond the atmosphere, and then conquer the entire solar system." — Konstantin Tsiolkovski (1857–1935)

A founding project

Like Christopher Columbus approaching a new world, this project imagines the first milestones of a permanent human presence on the Moon.

Context READ →

More than fifty years ago, the Apollo missions demonstrated the feasibility of lunar travel. This project explores the next step: designing a durable, habitable and evolving architecture on the surface of the Moon, in response to the energy, scientific and human challenges of the 21st century.

Architectural approach READ →

The project integrates the radical constraints of the lunar environment — absence of atmosphere, radiation, extreme thermal variations — as founding data of the architectural project. The objective: to create a pleasant living environment, in harmony with a high-technology universe, while expressing the symbolic dimension of a new industrial era.

Man and the robot READ →

The Man/Robot complementarity structures the project. The robot performs specific tasks in hostile environments; man ensures reconfiguration, programming and decision-making. This synergy directly determines the spatial organisation of the base and the hierarchy of spaces.

Ambition READ →

Beyond the technical project, this lunar base is conceived as a lever for international cooperation, a catalyst for the terrestrial economy and the first link in an extended human presence in the Solar System.

Understanding the Moon

Before designing, one must understand. The physical and environmental characteristics of the Moon condition every architectural choice.

An atmosphere-free environment

The absence of a lunar atmosphere implies a total absence of water, extreme thermal variations (+120°C / −160°C) and direct exposure to solar and cosmic radiation.

The radiation challenge

Solar and cosmic radiation constitute the major risk for human life on the Moon. Radiation protection becomes a structuring principle of lunar architecture.

The riches of the lunar soil

Lunar regolith contains 30% metals, 20% silicon and 40% oxygen. These local resources are the key to the autonomy of any human colony.

Energy from the cosmos: SPS

Solar Power Satellites represent the opportunity to permanently capture solar energy and redistribute it on Earth, transforming the Moon into a global energy base.

The stages of conquest

From Sputnik (1957) to the MIR station, via Apollo and Skylab, a look back at the major milestones that made the idea of a permanent lunar base possible.

Living on the Moon

Lifestyle, weightless gardens, psychological balance, physical exercise: the design of the base must respond to human needs as much as technical ones.

The architectural project

Sited at the lunar south pole, in a large crater in the Leibnitz mountains — oriented towards the centre of our galaxy, symbolically open to the Universe.

Site

Large crater in the Leibnitz mountains — South pole, near side of the Moon. Reduced thermal range (Sun always on the horizon), facilitated access by polar orbit station passing every 2 hours.

The proximity of both sides of the Moon allows an observatory on each side: radio-astronomy on the far side, permanent observation of Earth on the near side.

Far-side observatory

Radio-astronomy without terrestrial interference. Unique ideal site in our solar system.

Polar orbital station

Passes above the base every 2 hours. Permanent Moon–Earth link.

Cosmic orientation

The base is symbolically oriented towards the centre of our galaxy, open to the Universe.
