Axiom Space and Prada have unveiled the Liquid Cooling and Ventilation Garment (LCVG), a critical inner layer for the Axiom Extravehicular Mobility Unit (AxEMU) spacesuit. Designed for NASA’s Artemis 4 lunar mission in 2028, the garment regulates astronaut body temperature and manages ventilation through an integrated system of water-cooling tubes, ensuring safety and comfort during moonwalks.
How the LCVG Protects Astronauts on the Moon
The LCVG serves as the innermost layer of the AxEMU, acting as the primary interface between the astronaut and the suit’s life support systems. According to Russell Ralston, senior vice president of spacecraft development at Axiom, the garment is essential because it is the piece closest to the astronaut, making comfort and functionality vital for safety. During lunar surface operations, the garment uses a network of tubes to circulate water, which absorbs body heat generated by physical exertion. This heat is then transported away and expelled, preventing the astronaut from overheating in the extreme lunar environment.

Engineering for Lunar Durability
The collaboration leverages Prada’s expertise in garment materials and production to address the specific hazards of the lunar surface. Axiom Space notes that the materials were selected not only for comfort but also to mitigate electrical charging issues caused by the plasma environment found on the moon. The design prioritizes ease of production, a factor Ralston highlighted as a necessary step toward the future of space exploration, where human presence in space could expand significantly. The suit also manages the intake of oxygen and the removal of carbon dioxide, which is filtered through the broader life support system integrated into the AxEMU.
Evolution of the Artemis Program
While the AxEMU is slated for the Artemis 4 mission in 2028, the path to the lunar surface has seen adjustments. NASA has shifted its strategy, focusing initial efforts on testing operational systems in low-Earth orbit before proceeding to later lunar landings. The outer layer of the AxEMU was previously unveiled by the companies in October 2024 at the International Astronautical Congress in Milan. By separating the development of the inner cooling garment from the outer protective shell, Axiom and Prada aim to create a modular, reliable system capable of supporting long-duration missions.
Pro Tip: Why Material Science Matters
In space environments, static electricity and extreme temperature fluctuations are constant threats. Using specialized materials for the LCVG prevents the buildup of charges that could interfere with sensitive electronics or pose risks to the astronaut, demonstrating how terrestrial fashion technology is being adapted for extraterrestrial survival.
Frequently Asked Questions
- What is the LCVG? It is the Liquid Cooling and Ventilation Garment, an inner layer of the AxEMU spacesuit that provides cooling and regulates body temperature.
- When will this suit be used? The AxEMU, including the LCVG, is scheduled to be worn by astronauts starting with the Artemis 4 mission in 2028.
- Who designed the suit? The suit is being developed by Axiom Space in partnership with the luxury design house Prada.
- How does the cooling system work? Water is circulated through a network of tubes within the garment to absorb heat, which is then moved to a system that expels it into space.
