A NASA lunar orbiter has, for the first time ever, returned photographs showing footprints and tire tread marks on the surface of the moon, as left there decades ago by the Apollo astronauts.

NASA said it was looking into protecting the lunar "heritage sites" from possible damage from future spacefaring vehicles, as the imprints left by mankind's first extra-terrestrial vacation will remain -- if untouched -- for over a million years thanks to a distinct lack of wind or other weather patterns on the moon.
