A puzzle that has frustrated scientists and sci-fi writers alike is how to limit the impact of low-gravity on the bodies of astronauts in space. Some have tinkered with complex mechanical solutions; others have looked instead to… the funfair. A “Wall of Death” traditionally involves daring motorcyclists riding horizontally around a wooden cylinder, defying gravity by keeping up their speed. Using bungee cords to simulate the moon’s low-gravity, researchers found that humans can safely run around these structures too, and that the force on their bodies should, in space, limit bone demineralisation and keep the respiratory system working. Engineers would not even have to build extra facilities. There are suggestions that astronauts could simply run around “the circular wall of astronauts’ inhabited settlements.” A few laps a day would be enough for those living in space for a long period (like those who would live on the moon as part of Nasa’s Artemis programme) to stay fit and healthy for a return to Earth. And to train for Mars.
