When astronauts step onto the moon for the first time in over five decades, they will be wearing a spacesuit whose inner layer was designed by a luxury fashion house. Axiom Space and Prada have unveiled the inner garment of the next-generation lunar spacesuit — a liquid cooling and ventilation system that could mean the difference between life and death in the harsh lunar environment.
What the Prada-designed inner layer does
The newly revealed inner layer is a liquid cooling and ventilation garment (LCVG) that fits directly against the astronaut's skin. It circulates chilled water through a network of tubes to regulate body temperature during moonwalks, which can last up to eight hours. The garment also removes excess humidity and carbon dioxide from the suit's breathing atmosphere.
Why temperature control matters on the moon
The moon's surface is brutal. During the lunar day, temperatures can soar to 250°F (121°C). At night, they plunge to minus 280°F (-173°C). Without proper thermal regulation, astronauts could suffer heatstroke or hypothermia within minutes. The LCVG acts as the body's radiator, keeping astronauts comfortable and functional during extended extravehicular activities.
How the Axiom-Prada partnership evolved
Axiom Space won the NASA contract to develop the next-generation lunar spacesuit in 2022, valued at up to $3.5 billion. In 2023, the company announced a partnership with Prada to bring advanced materials expertise and design innovation to the suit. The full AxEMU (Axiom Exploration Extravehicular Mobility Unit) was first shown in October 2023, but the inner layer remained under wraps until now.
What this means for astronauts
For the Artemis III crew — the first humans to land near the lunar south pole — this suit represents a leap forward from the Apollo-era designs. The AxEMU offers greater mobility, allowing astronauts to bend, squat, and pick up samples more easily. The inner layer's improved cooling system means longer, safer moonwalks. "This is not just about fashion," an Axiom official said. "It's about survival and performance."
What Axiom and Prada say about the design
Axiom Space described the inner layer as "a critical component" that integrates advanced thermal control with comfort. Prada's contribution focused on material selection and ergonomic design, ensuring the garment fits well under the hard outer shell. "Our expertise in high-performance textiles and precision manufacturing has been applied to meet the extreme demands of space," a Prada spokesperson said.
The science behind the liquid cooling garment
The LCVG works by circulating temperature-controlled water through a network of small-diameter tubes sewn into a stretchable fabric. The water absorbs body heat and carries it to a sublimator in the backpack, where it is vented into space as vapor. This closed-loop system can handle metabolic heat loads of up to 1,000 watts — equivalent to a person running at full sprint.
Confirmed facts vs what remains unclear
Confirmed: The inner layer uses liquid cooling technology. Confirmed: Prada contributed to material selection and design. Confirmed: The suit is intended for the Artemis III mission. Unclear: The exact timeline for final testing and certification. Unclear: Whether the suit will be ready for the current 2027 target date. Unclear: The specific materials used in the garment, as Axiom has not disclosed full technical specifications.
Why Axiom Space matters in the space industry
Axiom Space is not just a spacesuit contractor. The company is building the first commercial space station module, set to attach to the International Space Station before becoming an independent orbital outpost. Its partnership with NASA on the AxEMU suit gives it critical expertise in human spaceflight systems. The Prada collaboration also signals a shift toward cross-industry innovation in space technology.
Risks and challenges ahead
Developing a lunar spacesuit is extraordinarily complex. The AxEMU must withstand micrometeoroid impacts, extreme temperature swings, abrasive lunar dust, and radiation. The liquid cooling system must be leak-proof and reliable for multiple uses. Critics have questioned whether a fashion brand's involvement adds real engineering value or is primarily a marketing exercise. Axiom insists Prada's material science expertise is genuine.
How spacesuit design is changing
The AxEMU represents a broader trend: spacesuits are becoming more specialized and comfortable. NASA's earlier xEMU program was canceled due to cost overruns. Axiom's commercial approach, with private sector partners like Prada, aims to deliver a suit faster and cheaper. Other companies, including SpaceX, are also developing their own suits for lunar and Mars missions.
What you should know about the Artemis mission
For space enthusiasts and taxpayers: The Artemis III mission aims to land the first woman and the first person of color on the moon. The spacesuit is a critical piece of hardware. For students and professionals: The AxEMU demonstrates how advanced textiles, thermal engineering, and human factors design come together in extreme environments. For investors: Axiom Space's progress on the suit is a key milestone for the company's valuation and future NASA contracts.
What happens next
The inner layer will now undergo rigorous testing, including thermal vacuum chamber tests, pressure tests, and human-in-the-loop evaluations. Axiom plans to deliver the final flight-ready suits to NASA by late 2026. The Artemis III launch is currently scheduled for 2027, though space schedules are notoriously fluid. If successful, the AxEMU will be the first new lunar spacesuit in over 50 years.
Our Take
The unveiling of the inner layer is a quiet but significant milestone. Spacesuits are the most personal piece of space hardware — they are essentially a spacecraft worn on the body. Getting the thermal regulation right is non-negotiable. The Prada partnership, while attention-grabbing, appears to have contributed genuine material science expertise. The real test will come when astronauts put on the full suit and step onto the lunar surface. Until then, every component reveal builds confidence — or raises questions.
Frequently Asked Questions
What is the Axiom Prada spacesuit inner layer?
It is a liquid cooling and ventilation garment (LCVG) worn under the hard outer shell of the AxEMU lunar spacesuit. It circulates chilled water to regulate astronaut body temperature during moonwalks.
Why did NASA choose Prada to design the spacesuit?
NASA's contractor Axiom Space partnered with Prada for its expertise in advanced materials, high-performance textiles, and precision manufacturing. Prada's contribution focuses on the inner layer's comfort and thermal performance.
When will the Prada spacesuit be used on the moon?
The AxEMU suit is intended for NASA's Artemis III mission, currently targeted for 2027. The suit must pass extensive testing before being certified for lunar use.
How does the liquid cooling garment work?
The garment has small tubes sewn into a stretchable fabric. Temperature-controlled water flows through the tubes, absorbing body heat. The heat is then vented into space through a sublimator in the suit's backpack.
