Astronauts at NASA, working alongside industry collaborators, are intensifying preparations for the Artemis program, which aims to send humans back to the lunar surface for the first time in over five decades.
This ambitious mission requires extensive testing and readiness verification of all equipment and systems involved in lunar exploration. Central to these efforts is the assessment of cutting-edge spacesuits and spacecraft hardware tailored for Artemis flights.
Recently, astronauts Doug “Wheels” Wheelock and Peggy Whitson wore new spacesuits crafted by Axiom Space to interact with a life-sized prototype of SpaceX’s Starship Human Landing System (HLS). This event marked the inaugural occasion astronauts operated in pressurized suits while interfacing with the Starship HLS test assembly, marking a crucial achievement for the Artemis initiative.
In-Depth Validation of Emerging Technologies
The extensive evaluation, held at SpaceX’s facility in Hawthorne, California, generated vital insights into the Starship HLS, with attention paid to the internal layout, mechanical components, clearances, and the maneuverability offered by the AxEMU (Axiom Extravehicular Mobility Unit) suits worn during the test.
Wheelock and Whitson donned the AxEMU suits inside a full-scale airlock mockup located on Starship’s airlock deck. External systems supplied pressurized air, power, cooling, and communication to support the astronauts’ operations. Each suit featured a realistic model of the Portable Life Support System — the essential backpack apparatus for upcoming lunar excursions.
NASA and SpaceX teams examined the position and usability of mobility aids, including handrails designed to assist passage through hatches. Additional aids, such as ceiling-mounted straps, helped the astronauts with the tasks of entering and removing the AxEMU suits. The astronauts also practiced operating an airlock control panel while wearing their gloves, ensuring that controls were both accessible and functional. According to Logan Kennedy, lead surface activities coordinator for NASA’s HLS Program, the astronauts effectively managed these controls and performed critical operations envisioned for lunar surface work.
Training for Moonwalks and Surface Activities
After suiting up, the astronauts moved from Starship’s airlock deck to a test elevator, designed to simulate the transport system that will move crew and gear between the spacecraft and the Moon’s surface during Artemis missions. Wheelock and Whitson practiced opening the elevator hatch and assessed the dexterity provided by the AxEMU suit gloves. These rehearsed motions within the full-scale Starship hatch, airlock, deck, and elevator models are vital groundwork for the lunar exploration planned with Artemis.
For the upcoming Artemis III mission, SpaceX will supply the Starship HLS which will rendezvous and dock with Orion in lunar orbit to ferry two astronauts to and from the Moon’s surface. The new spacesuits offered by Axiom Space cater to broader astronaut body types, enhancing mobility and safety for extravehicular activities. These partnerships emphasize the innovative technology and teamwork essential to achieving success in deep space missions.
Paving the Way for Extended Space Exploration
Through Artemis, NASA plans to explore more of the lunar terrain than ever before, gaining critical knowledge on sustained living and operations beyond Earth while setting the stage for crewed Mars missions. Supporting hardware such as the Space Launch System (SLS) rocket, Orion spacecraft, ground support, human landing systems, next-gen spacesuits, the Gateway lunar station, and future lunar rovers collectively build the infrastructure for extended exploration. The rigorous testing of these integrated systems is key to ensuring astronauts are equipped with reliable, high-performance tools needed for upcoming voyages.
The efforts of Wheelock and Whitson in evaluating Starship components and new spacesuits mark vital progress toward Artemis milestones. As NASA and its collaborators continue refining these capabilities, each successful trial advances humanity’s quest for its next momentous steps on the Moon and eventually, Mars.
