If a astronaut landed on the moon how long would the footprints stay there and why?
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.
