How long (millions of years I suspect) before the micrometeors reduce them to dust?

Barring a direct hit by a meteorite or a large piece of ejecta, I wouldn't be surprised if there is something recognizable at those sites for a billion years or longer. Visiting the sites and studying actual micrometeorite impacts and radiation effects since launch would give us a more accurate estimate.

Souvenir collectors can do a lot of damage over a billion years.

According to this (http://moonphases.info/) the footprints there should last 10 million years.
I imagine the more solid stuff should last much longer, assuming the site is not disturbed.
