Why are there footprints on the Moon that can last for a very long time?
AstronomyMoon
Quick Answer
The Moon has no atmosphere, wind, or liquid water to erode footprints, so they can persist for millions of years unless disturbed by impacts.
The Full Story
On Earth, wind, rain, and erosion quickly erase footprints, but the Moon is an airless world. With no weather and almost no surface activity, a footprint made by an astronaut or rover can remain unchanged for an extremely long time. Micrometeorite impacts and larger collisions can eventually disturb the surface, but not on the timescale familiar on Earth. That is why Apollo landing sites can still preserve tracks and equipment decades later.
