Impact of Low Gravity on Astronauts During Apollo Mission During the Apollo missions, astronauts experienced the Moon’s low gravity, which is about one-sixth of Earth’s gravity. Because of this, astronauts walked differently, often hopping or bouncing instead of walking normally. Their movements looked slow and unusual, but this was a natural effect of low gravity and bulky space suits. Low gravity also made it easier to lift heavy equipment, but harder to maintain balance. Astronauts had to lea
