These incredible images will undoubtedly be used by conspiracy theorists who are still convinced that the six Apollo missions that landed on the moon never actually happened. However, there is a consensus that this moon is artificial yet incredibly realistic. With its help, European astronauts will be able to train for lunar operations! At least on Luna, a surface recreated in a large hangar located in Cologne, Germany.

Several of these facilities exist worldwide, particularly in the United States and Japan, but none have achieved such a high level of realism. Luna encompasses 700 m² of a geological replica of our natural satellite, utilizing basalt dust as a substitute for the lunar regolith. The communication conditions mirror those of real missions, with a background screen simulating the Sun appearing very low on the horizon as it will during the Artemis missions. By 2026, a system of ropes will simulate lunar gravity, which is six times weaker than that of Earth! The total investment cost is approximately $45 million, funded by the German federal government, the DLR Aerospace Center, and ESA.

Lunar regolith is extremely fine dust produced from crushed meteorites over billions of years.
The real Moon is covered with a thick layer of regolith, consisting of fine grains (10-50 micrometers) that are sharp, capable of infiltrating everywhere, and radioactive. These grains were deposited over billions of years due to meteorite impacts on the lunar surface. For Luna, ESA utilized 900 tonnes of terrestrial basalt dust to recreate this environment as accurately as possible, with a depth of 50 cm!
The hangar is sufficiently spacious to train astronauts, as well as robots and rovers that will eventually set foot on the surface of our neighboring celestial body. As a reminder, ESA is involved in the American Artemis program aimed at returning to the lunar surface, having notably designed the Orion capsule. There remains hope that a European astronaut will one day walk on our satellite, and if that happens, Thomas Pesquet would have a good chance of being selected.

Luna: The Realistic Moon Simulation for Astronaut Training
These are astonishing images that conspiracy theorists will no doubt use, still convinced that the six Apollo missions that touched the lunar surface never took place. Here, everyone will nevertheless agree: this moon is fake and very realistic. Thanks to it, European astronauts will be able to train to work on the Moon! At least on Luna, a surface recreated in a large hangar in Cologne, Germany.
Several of these sites exist around the world, notably in the United States and Japan, but Luna offers a level of realism unmatched by its counterparts. With 700 m² of geological reproduction of our natural satellite using basalt dust as a replica of the lunar regolith, and communication conditions identical to real missions in the making, Luna aims to prepare astronauts for the challenges of the Artemis program.
By 2026, a mechanism made of ropes will simulate lunar gravity, which is six times weaker than on Earth! The overall investment cost is approximately $45 million, funded by the German federal government, the Over-the-Rhine Aerospace Center DLR, and the European Space Agency (ESA).

The Importance of Lunar Regolith
Lunar regolith is very fine dust made from crushed meteorites over several billion years. The Moon is covered with a thick layer of regolith composed of fine grains (10 to 50 micrometers) that are sharp and capable of infiltrating equipment. This regolith is also slightly radioactive, adding further challenges for astronauts.
For the Luna facility, creating an authentic lunar environment meant using terrestrial basalt dust, ensuring that the trained astronauts fully understand the dynamics of working with lunar materials.
Benefits of the Luna Training Facility
- Enhanced Training Experience: With realistic conditions, astronauts can better prepare for the unique challenges of navigating and working on the lunar surface.
- Improved Safety: Effective training can reduce the risks associated with actual lunar missions, ensuring that astronauts are equipped to deal with unexpected situations.
- Collaboration Opportunities: The facility promotes international cooperation between space agencies like ESA and NASA, furthering scientific endeavors.
Practical Tips for Aspiring Astronauts
- Physical Training: Maintain a high level of physical fitness, as working in lunar gravity requires different physical capabilities.
- Technical Skills: Acquire skills in engineering and robotics, as these will be fundamental in missions involving rovers and robotic assistance.
- Teamwork: Develop strong teamwork and communication skills, as missions require seamless collaboration among crew members.
A Glimpse into the Future of Lunar Exploration
The Luna training facility stands as a beacon of innovation in astronaut training, designed with the future of lunar exploration in mind. ESA plays a significant role in the Artemis program, contributing to the development of the Orion capsule and planning human exploration of the Moon.
As we look toward the future, the prospect of European astronauts like Thomas Pesquet landing on the Moon seems increasingly feasible. This facility not only prepares them for their journeys but represents humanity’s hope for exploration beyond Earth.
Robotic Exploration and Its Significance
In addition to training astronauts, the Luna facility is also designed to prepare robotic systems for lunar missions. The development of rovers and autonomous systems will be essential for exploring areas of the Moon that are hazardous for human missions.
Implementing robotic exploration will not only assist astronauts once they land on the lunar surface but also facilitate essential tasks such as sample collection and environmental assessments, laying the groundwork for sustainable missions.
