The bootprints Neil Armstrong and Buzz Aldrin pressed into the Sea of Tranquility on 20 July 1969 will still be visible roughly a million years from now, because the Moon has no wind, no rain and no biology to wear a footprint away — only micrometeorites slowly gardening the regolith around them
The bootprints Armstrong and Aldrin left in the Sea of Tranquility on 20 July 1969 are still crisp today, and will remain recognisable roughly a million years from now. The Moon has no wind, no rain and no biology to wear them away — only micrometeorites, working with tweezers on a geological clock.
