What the Prada–Axiom Liquid Cooling Garment Is and Why It Matters
The Liquid Cooling and Ventilation Garment is a form‑fitting, tube‑lined inner layer of the NASA Artemis spacesuit, designed by Prada and Axiom Space to keep astronauts’ bodies stable and ventilated during long, demanding moonwalks in extreme lunar temperatures and vacuum conditions. This liquid cooling garment, known as the LCVG, is the first layer astronauts step into when donning the AxEMU, the next‑generation NASA Artemis spacesuit for lunar surface work. A light gray textile stretches over the body while clear tubing traces the torso, arms, and legs, and a single red stripe down one sleeve nods to Prada’s sportswear heritage. Revealed publicly at an event in New York, the Prada spacesuit inner layer turns a normally hidden piece of life‑support hardware into a precision‑engineered garment that blends astronaut thermal regulation, ventilation, and high‑end textile design into one integrated system.
How Water, Tubes and Life Support Keep Astronauts Cool
At the core of the Axiom Space cooling layer is a dense network of narrow tubes that route over major muscle groups to control heat and airflow. Cold water circulates through the primary loop, absorbing metabolic heat as astronauts work through spacewalks lasting up to eight hours, before the warmed fluid flows to the portable life support system on the back, where its heat is released into space. A fully independent backup loop runs alongside it; if the main circuit fails, the secondary loop takes over without interrupting temperature control. A separate set of tubes supports ventilation, carrying fresh oxygen across the astronaut’s face while exhaled carbon dioxide is collected and scrubbed before being recirculated. According to Axiom Space, the LCVG will be “one of the few layers standing between [astronauts] and the unforgiving environment of space.”
Fashion House Meets Space Lab: Inside the Prada–Axiom Collaboration
The Prada spacesuit project marks an unusual bridge between a luxury fashion house and a commercial space company, with each side bringing distinct strengths. Prada contributed decades of knowledge in high‑end textiles, engineered knitting and precision pattern making, helping select fibers that can survive repeated use and harsh lunar conditions. Axiom Space supplied aerospace engineering, life support integration and advanced 3D modeling tools that mapped each tube path to maximise cooling efficiency while preserving mobility. The teams iterated through multiple models to see which materials and tube layouts worked best across different body types. Axiom and Prada had already collaborated on the AxEMU’s outer shell, designed for thermal extremes and micrometeoroid hazards at the lunar south pole, and the LCVG was the next logical step inward. Together, they aim to create a NASA Artemis spacesuit system that is both technically capable and tailored to a wider range of astronauts.
Redefining Comfort and Safety for Artemis Moonwalkers
Beyond aesthetics, the new liquid cooling garment is meant to fix limitations in older spacesuits used on the International Space Station. Previous inner cooling layers lacked a redundant circuit, making them more vulnerable to a single failure, and they were not designed with lunar‑specific issues such as plasma interactions in mind. The AxEMU LCVG’s dual cooling loops, upgraded ventilation and materials tuned for the Moon are intended to expand safety margins and endurance on the surface. Engineers also targeted fit and customisation so the NASA Artemis spacesuit can serve a broader, more diverse astronaut corps while supporting both lunar excursions and microgravity work. The qualification hardware is undergoing ground testing now, with an in‑space demonstration planned before the system supports crewed Artemis IV missions later this decade, where it could redefine how astronauts stay cool, comfortable and effective on the Moon.
