For NASA's Artemis III mission—the first human Moon landing since Apollo—astronauts will don advanced, safer, and more efficient spacesuits. But a recent report reveals they won't be ready by the 2024 target.
Spacesuits serve as personalized spacecraft, sustaining astronauts in the vacuum of space. NASA's current models, rooted in Apollo-era designs, have proven reliable but come with limitations. With goals to return to the Moon and eventually reach Mars, the agency has invested over 14 years in redesigning them.
The result is the Extravehicular Mobility Unit (xEMU), customized via 3D body scans for perfect fit. These suits endure extreme lunar conditions: -120°C in shade and +120°C in sunlight. The portable life support system (PLSS)—delivering oxygen and scrubbing CO2—is more compact, enabling longer spacewalks.
Upgrades include helmets with enhanced audio for clearer communication and quick-swap visors. New joints at the hips, knees, and shoulders provide greater mobility for lunar exploration.
These suits promise major advancements, yet development has fallen behind. A 2017 audit, after nearly $200 million spent, flagged timeline risks.
NASA has since added $220 million, totaling $420 million. Still, a new audit indicates the first two flight-ready suits won't arrive until April 2025 at earliest, citing funding gaps, COVID-19 disruptions, and technical hurdles.
Elon Musk offered SpaceX's assistance, but NASA's November 2024 readiness goal for xEMU suits now appears unachievable.
Spacesuit delays are just one issue; challenges with the SLS rocket, Orion capsule, and SpaceX's lunar lander—further slowed by Blue Origin protests—also jeopardize the 2024 landing, per the report.
