Apollo 12 astronaut Alan Bean was the fourth man on the Moon. In 1981, he retired from the space agency to put his otherworldly experiences on canvas. Seen above, "Tiptoeing on the Ocean of Storms" (acrylic on masonite). Bean's magnificent paintings are currently on display at the National Air and Space Museum in Washington DC. From the Smithsonian:
Bean remembers running next to this crater and feeling like he could run forever without his legs getting tired. The reason he felt "super strong" was because he weighed so little. The Moon has one-sixth the gravity of Earth, making his total body and equipment weight of about 136 kilograms (300 pounds) on Earth only 23 kilograms (50 pounds) on the Moon."Alan Bean: Painting Apollo, First Artist on Another World"
Although carrying weight required little effort, the spacesuits were stiff and hard to move at the knee and hip joints. Astronauts learned to move mostly by ankle motion, which Bean says "feels and looks as if you are dancing on tiptoe."
