Well it probably depends on the space boots are heavy, but about millions of years.
Until something disturbs it, like a future meteor impact, or a future moon landing. The footprints left by the astronauts may last millions of years.
In 7,000 years
Until something disturbs it, like a future meteor impact, or a future moon landing. The footprints left by the astronauts may last millions of years.
There were recent amazing pictures released to the press of the surface of the moon which showed many of the objects left on the moon including footprints! So you know the footprints last over 40 years because it has been that long since Neil Armstrong made history with the first footprints on the moon. There is no atmosphere on the moon therefore no rain, wind or water flow so the only thing that will destroy the footprints is space debri of either man made materials or rocks such as a meteor storm. Scientist from different nationsintentionally crash objects into the moon for various studies.
Ten Million Years
As long as no one touches or disturbs them, footprints on the Moon will look the same, and will remain unchanged forever. On the moon, there is no wind that would cover the footprints, and there is no water or rain that would wash the footprints away.
Because there's no gravity or wind.
There is no wind, and barely any gravity so the footprints will stay on the moon for yyyyyeeeeaaaarrrrrrsssss.
Because there is no wind on the moon to blow it around.
There is gravity on the moon, it is just weaker than it is on Earth. There is fine sand on the moon. if you step on it, of course there would be footprints.
We can't be absolutely sure how long a footprint will last on the moon since it might or might not be struck by a meteoroid or other cosmic debris, but potentially it could last for billions of years. It is also possible (although I am not expecting it) that the moon will someday be colonized by people, who will then disturb the existing footprints. But then again, they might want to preserve them as monuments.
Footprints in the moons surface (so in the dust lying on the moon) will never go away because there is no wind on the moon to blow new dust over the footprints.
