The hazards of Moon dust

Despite all the attention lavished on Moon dust, we still don't know what effect the stuff has on human lungs ... which is kind of a big deal, considering the fact that the dust has busted through every vacuum seal its ever faced. And eaten through layers of moon boots. Basically, you can imagine Moon dust as those tiny shards that get left on the floor when you break a glass and inevitably end up embedded in your foot four days later. At The New Yorker, Kate Green writes about efforts to better understand the effects of Moon dust on various materials and how engineers are trying to find new ways to control it before humans return to the lunar surface.
