Circularity in Space: CLIMATEX on a lunar mission
Moon simulator, space environment, the world's best astronauts – and right in the middle of it all: CLIMATEX textiles! Circular materials play a crucial role in the ultra-modern space habitat "FLEXHab", designed and built by SAGA Space Architects. We are proud to have made a small contribution to this pioneering project!
"FLEXHab" has been at the European Space Agency (ESA) in Cologne since the beginning of April.
"The materials astronauts come into contact with on a daily basis are of the utmost importance. Quality and sustainability are key. And CLIMATEX offers exactly what we need: durable, aesthetically pleasing and recyclable textiles," says Sebastian Aristotelis, Co-Founder and Lead Architect of SAGA, explaining the importance of our fabrics in the interior design of the space habitat. "Sustainability and above all recyclability are essential on the Moon, where resources are even more limited than on Earth," he continues. In addition, the materials used must not release any harmful emissions or aerosols into the air, as it is already circulating in a closed cycle in training mode.
Textile surfaces are crucial to the comfort and functionality of the interior. They are used on walls, seats and other touch points. Not only do they need to be natural and durable, but they also need to withstand extreme conditions and heavy use. Sebastian Aristotelis explains that the aesthetic requirements for the variety of colours and textures of the textiles are based on the cognitive stimulation of the astronauts, which needs to be supported.
A milestone in lunar exploration
The "FLEXHab" will serve as a training habitat for the Artemis lunar mission, planned for 2026, when mankind will return to the Moon. At the beginning of April, the European Space Agency (ESA) completed the construction of "Luna", the world's largest lunar simulator, at the European Astronaut Centre (EAC) in Cologne, Germany. "FLEXHab", which is directly linked to this 1000 square metre facility, offers astronauts such as the well-known German space researcher and astronaut Matthias Maurer the opportunity to prepare for such missions.
From the hall with dust, stone and no fresh air, the astronauts go directly into the "FLEXHab". Thanks to the suitport – a special airlock for direct access to the lunar surface - crews of four can train in space conditions for up to seven days. In just 28 square metres, equipped with state-of-the-art technology and a circadian lighting system to support sleep patterns, the FLEXHab will provide space for astronauts to live, work and sleep. The first training missions in this habitat will begin this spring.
"I am very excited to see our new 'FLEXHab-LUNA' module in action. It is the heart of our new training centre and completes the simulation of the lunar surface with the intravehicular area of a lunar lander or lunar base. FLEXHab will enable complex, fully integrated multi-day missions," said Matthias Maurer, ESA astronaut and project manager, in a press release.
Since its establishment in 2018, SAGA Space Architects has made a name for itself in the development of analogue space habitats. "FLEXHab is the fifth habitat developed by SAGA and builds on the experience gained from previous projects and test missions. Sebastian Aristotelis personally tests all structures and has already spent 100 days in the Arctic and 48 hours underwater to test the resilience and functionality of the designs.
"The FLEXHab is the most advanced training habitat ever developed for astronauts. Equipped with SAGA's Circadian Lighting Technology, which helps astronauts maintain their natural cicadian rhythms and is already being used on the International Space Station (ISS), it is designed to increase the crew's well-being and performance.
