NASA’s astronauts are gearing up for another lunar excursion, and this time they’ll be wearing a spacesuit engineered for the modern age. The agency has started trials on a newly designed spacesuit created byAxiom Space, marking a crucial stage in preparation for theArtemismissions to the moon. These experiments are being conducted at NASA’s famousNeutral Buoyancy Laboratory (NBL)In Houston, astronauts get a near-Moon-walking experience by submerging themselves in a massive 6.2-million-gallon underwater simulator.
A Spacesuit Engineered to Withstand the Moon’s Most Extreme Conditions
The Axiom’s spacesuit for spacewalks (AxEMU)surpasses its Apollo-era forerunners in more than just appearance. It signifies a significant advancement in technology, specifically designed to withstand the harsh conditions of the moon. It was developed byAxiom SpaceThe AxEMU is specifically designed to endure harsh temperatures, rough landscapes, and extended moonwalks on the lunar surface. NASA astronauts will be required to navigate through dusty inclines, gather rock and soil specimens, and use research tools in environments much more challenging than those encountered on the ISS.
To address these requirements, AxEMU provides improved capabilities.mobility, better sizing flexibilityTo better fit astronauts of varying sizes, and improved.life-support systemsTo support extended space travels, it features adaptable tools and customizable parts for enhanced accuracy in research. The suit also emphasizes.visibility and dexterity, thereby enhancing astronauts’ command over intricate tasks. This all aligns with NASA’s long-term goal of a continuous human presence on the Moon, beginning with the Artemis III mission.
Practicing Underwater to Get Ready for Lunar Missions
The latest workshop held at theNeutral Buoyancy Laboratory saw astronauts Loral O’Hara and Stan LoveCarry out comprehensive underwater simulations using a pair of fully integrated AxEMU suits, as outlined in the.Space.com report by journalist Kenna Hughes-Castleberry, this marked the first dual-suit operational test, with both astronauts suited up simultaneously to simulate real lunar fieldwork.
The NBL allows astronauts to experience neutral buoyancy, mimicking microgravity. In this controlled underwater environment, they practiced collecting rocks, navigating uneven surfaces, and coordinating team-based tasks, all while adapting to the constraints and capabilities of the new suit. These activities are not simply exercises—they’re essential rehearsals for what crews will do on the lunar surface. NASA used the session to evaluate suit performance, mission protocols, and systems support—verifying that the infrastructure is ready for real Artemis mission training.
This test also helped engineers observe how the AxEMU’s life-support systems function under simulated stress and coordination between multiple astronauts. Feedback from these simulations is now feeding directly into refinements of both suit design and lunar mission planning.
Why The AxEMU Is Key To Artemis’ Long-Term Success
Unlike the Apollo missions, which involved brief lunar visits, the Artemis program aims to establish a sustainable human presence on the Moon. That means everything astronauts wear, use, and carry must endure longer exposure to lunar conditions. The AxEMU plays a foundational role in this strategy.
NASA’s choice to partner with Axiom Space, a private aerospace firm, reflects its commitment to leveraging commercial innovation. This collaboration has led to the development of a suit that not only meets NASA’s scientific and operational requirements but also sets a new benchmark for next-generation space exploration gear. The AxEMU is built with modularity in mind, which allows it to be adapted for future use beyond the Moon, potentially even for Mars missions.
By training with this suit now—well ahead of Artemis III’s expected launch—NASA is not only ensuring astronaut readiness but also advancing its goals of exploration, science, and international cooperation. The NBL tests serve as a stress-test for the suit, but also for NASA’s broader mission architecture.
What Comes Next In Artemis Lunar Prep
With the AxEMU’s successful underwater trials behind them, NASA’s Artemis crews are preparing for the next stage of training: surface simulations in lunar analog environments on Earth. These will further refine movement, equipment use, and communication protocols in conditions that replicate the Moon’s regolith and lighting.
Meanwhile, engineers will incorporate data from the underwater tests to adjust suit mechanics, joint resistance, and comfort factors. NASA’s timeline for Artemis III is aggressive, but structured—each step, including this recent milestone, builds toward not just planting another flag on the Moon, but learning to live and work there.
The success of the AxEMU is not just a technical achievement—it’s symbolic. It reflects the growing integration of private industry and national space agencies in realizing humanity’s ambitions beyond Earth. And as astronauts take their first steps in these suits beneath the surface of a pool, they’re preparing to step onto a surface not visited by humans in over half a century.
