The Artemis program isn’t just a return to the moon but a leap into its harshest polar regions, where temperatures plummet to a staggering -369°F (-223°C).
Unlike the Apollo missions, which explored milder equatorial zones, Artemis will face the brutal extremes of the lunar south pole, demanding cutting-edge technology for survival.
Astronauts’ boots, critical for moonwalks, must endure intense cold and incorporate rigid thermal plates that hinder natural foot movement, introducing new mobility challenges.

Current lunar boots restrict the MTP joint in the big toe, essential for walking. This stiff design may compromise movement and efficiency, risking long-term injuries.

The windlass mechanism, crucial for converting the foot into a rigid lever for walking, may struggle to function under lunar gravity with restrictive boots, affecting gait stability.

Kinesiologists warn that restricted foot movement could lead to injuries, impacting the kinetic chain and causing strain on the upper body due to compensatory adjustments.

At the University of North Dakota, researchers study human movement in extreme environments, aiming to optimize gait and spacesuit design for long-term lunar missions.

Short-term stays may be manageable, but prolonged lunar missions introduce the risk of chronic injuries as foot strain affects posture, gait, and overall astronaut health.
NASA’s focus on lunar gait research will guide spacesuit and boot innovations, ensuring astronauts can navigate the moon’s polar extremes safely and effectively.
