2. The Apollo Astronauts’ Footprints Will Probably Stay There For Over 100 Million Years.
Since there is no atmosphere on the moon, there’s no wind or water that can erode or wash away the Apollo astronauts’ trails on the moon. Therefor their footprints, rover prints, spaceship prints, and discarded materials will stay preserved for a very long time on the moon.
But they won’t be on there for eternity . The moon still a pretty dynamic environment as it constantly gets bombarded with “micrometeorites,” which means that erosion is still happening on the moon, just at a very slowly rate.
