Footprints of Apollo Astronauts

When the Apollo astronauts walked on the surface of the Moon, they left a mark that would remain there for a very long time. In a previous study of lunar rocks collected by astronauts during the Apollo missions, researchers found that the rocks disintegrate at a rate of about 0.04 inches per million years. "From a human point of view, this may seem like an eternity, but from a geological point of view, there may be no traces of the Apollo probes for 10 to 100 million years," said Mark Robinson, a scientist of Arizona State University.
The eventual disappearance of the human footprint on the Moon could encourage some form of protection for the places where the Apollo astronauts landed and explored. "Because the moon has no atmosphere, wind and water erosion doesn't dissipate as quickly as on Earth, so it has a more permanent characteristic."

So if we don't act to protect these places, the forces of nature will take their course."
