The US is set to return to the Moon with NASA’s Artemis program, but the journey won’t be a straightforward walk in the park. The lunar surface offers one of the most extreme environments in the solar system, requiring new approaches to protect astronauts.
Unlike previous missions to the Moon 50 years ago, which focused on milder equatorial regions, Artemis aims to explore the lunar poles with temperatures as low as -369°F (-223°C). Current equipment designed for short-term stays won’t suffice for extended stays in this hostile region.
To address these challenges, researchers at the University of North Dakota are studying biomechanics and human movement patterns in extreme environments. Their research focuses on how astronauts move on the Moon while protecting their bodies.
One critical piece of equipment is the lunar boot, which needs to withstand harsh conditions unique to the southern pole. The current design incorporates a rigid thermal plate that restricts foot movement, particularly at the big toe joint. This could lead to issues with the windlass mechanism, essential for walking and pushing forward on the Moon.
If not addressed, foot injuries could affect other parts of the body, causing chronic injury up the kinetic chain. As NASA works towards sending astronauts back to the Moon, researchers must learn more about lunar gait and its effects under lunar gravity. This knowledge will aid designers in perfecting spacesuit designs for future missions.
