In preparation for a permanent lunar base, NASA scientists are exploring novel ways to mitigate the effects of space travel on astronauts. One such method involves having astronauts perform the daring ‘Wall of Death’ stunt, where they run around the inside of a barrel-shaped wooden cylinder. This stunt, which requires a running speed of just 8 mph (13 km/h) on the moon’s low-gravity environment, has been shown to be effective in preventing muscle and bone loss induced by microgravity. While there are logistical challenges in transporting a giant ‘Wall of Death’ to the moon, alternative solutions such as running around the walls of circular lunar habitats are being considered.
