No-fly zones will come into effect on the moon for the very first time by the end of this month! Why, even buffer zones that spacecraft may have to avoid will come into existence. The reason: avoiding any spraying of rocket exhaust or dust onto certain historical sites and artefacts on the moon.
The historical sites are of course the Apollo landing sites and artefacts present on the moon. And the “recommendations” are for preserving and protecting these historical sites. There are currently more than three dozen historical sites that preserve the more than four-decade-old remains.
