Running is more efficient than walking for humans wearing spacesuits on the moon, according to a new study. A laboratory simulation of moonwalking found that pressurized spacesuits act as springs for our legs, and on the moon this effect is most pronounced during activity where the knee is bending at a greater angle, such as running. These findings may help NASA develop more efficient and comfortable spacesuits for future moon explorers, while also assisting research in prostheses for amputees. And who knows, maybe it could even promote the first lunar marathon run.
