What the Liquid-Cooled Bodysuit Is and Why It Matters
Prada and Axiom Space’s liquid-cooled bodysuit is a precision inner garment that sits directly against astronauts’ skin, circulating water and air through embedded tubing to regulate body temperature and breathing during lunar surface operations in the AxEMU spacesuit. Designed as NASA’s next-generation cooling layer for Artemis missions, this inner garment forms one of the few physical barriers between astronauts and the harsh vacuum of space. Astronauts step into the light gray, form-fitting layer before donning the outer lunar spacesuit, turning what appears to be a sleek technical undergarment into a critical life-support interface. Its tubing routes over major muscle groups to pull heat away, while separate channels manage oxygen flow to the helmet. By combining thermal control and ventilation in a single wearable system, the garment keeps astronauts safe and functional through long moonwalks.
How the NASA Cooling Layer Controls Heat on the Lunar Surface
The new NASA cooling layer works by turning the astronaut’s entire body into a controlled heat exchanger. Water circulates through clear tubes laid across the torso, arms, and legs, absorbing heat from working muscles and transporting it to the portable life support system on the back. There, the warmed liquid releases its heat into space, preventing the astronaut from overheating in a suit that must remain sealed. Axiom explains that the LCVG, or Liquid Cooling and Ventilation Garment, “will be one of the few layers standing between [astronauts] and the unforgiving environment of space.” Separate ventilation tubing continues that job for breathing: fresh oxygen flows toward the helmet while exhaled carbon dioxide is collected, cleaned, and reused. A second, fully operational cooling loop runs alongside the first, allowing the backup circuit to take over instantly if the primary loop fails.
Prada Spacesuit Design: Fashion Craft Meets Lunar Engineering
The Prada spacesuit design effort focuses on the inner LCVG layer, where garment precision directly affects safety. Prada contributed decades of textile knowledge, advanced knitting, and pattern making to shape a bodysuit that fits closely yet flexibly around diverse body types. Light gray stretch fabric forms a smooth base, while the clear tubing’s paths are refined through 3D modeling tools provided by Axiom Space to balance cooling efficiency with freedom of movement. A single red stripe down one sleeve references Prada’s activewear heritage, a subtle reminder that this is also a fashion house garment. According to Axiom, Prada’s role extended to selecting specific fibers that can be reused across long-duration missions and withstand issues unique to the lunar environment, including plasma interactions that older spacesuits were never meant to handle. The result is a technical underlayer that blends luxury tailoring with strict aerospace tolerances.
From New York Reveal to Axiom Space Artemis Missions
The inner cooling layer was first revealed in New York, where Axiom and Prada showed how the LCVG fits beneath the AxEMU lunar spacesuit. This unveiling followed an earlier look at the outer suit, underscoring how high-fashion brands are entering the space exploration sector without sacrificing engineering demands. The garment is designed for eight-hour spacewalks and reuse across multiple excursions, aligning with Axiom Space Artemis plans to support crewed trips to the lunar surface later this decade. Ground qualification tests are underway, with an in-space demonstration scheduled before it sees service on future missions. Compared with the suits currently used on the International Space Station, this lunar spacesuit technology offers more customisation, better redundancy, and materials tuned for the moon’s environment. It marks a rare but growing intersection where luxury design and NASA cooling layer engineering advance human exploration together.
