Life in Low Gravity: How Apollo Astronauts Moved on the Moon Apollo mission astronauts worked on the Moon in very low gravity, only about 16% of Earth’s gravity. Because of this, normal walking was difficult. Astronauts used short steps, hopping, and bouncing movements to stay balanced on the dusty surface. Low gravity made objects feel lighter, but it also reduced traction, causing astronauts to slip or fall easily. Their space suits were heavy and stiff, which added to the challenge. Studying
