One of the Moon’s most surprising dangers is lunar dust. As everyone knows, sand gets everywhere even on Earth, but on the Moon, it is downright hazardous. Lunar dust is as fine as flour, yet extremely rough. Thanks to this texture and the Moon’s low gravity, it clings absolutely everywhere.
NASA has experienced numerous problems caused by moon dust. It has eroded astronauts’ boots almost completely through and sandpapered their visors.
It has traveled inside the ships with the space suits and caused “moon hay fever” in the poor astronauts that have inhaled it. It’s thought that prolonged exposure to the stuff could even cause airlocks to fail and space suits to break down. And in case you were wondering: Yes, of course this devilish substance smells like spent gunpowder.
