Moonglow

It has been reputably reported that the moon is covered in dust.  Not our dust. Not our tumbleweeds in the unswept corner dust, nor the dust the mother in law finds on every visit try as one might. This is the finer stuff - little nano-grains of dust caused by the surface being pelted with meteors.

The astronauts of  nearly half a century ago noted that when they tromped around on the surface this nano-dust floated up and because it had so little mass it just floated for a bit like when you shake your rugs on a airless summer day.  The moon's "room dust" is chock full of little pieces of glass - again the work of the meteors smashing things with such force that they pulverized the moon rocks and the heat made something like glass.

We have no idea why this little factoid is of interest.  Perhaps because it was so close last month or just because - well just because. The adventure of landing on the moon seems utterly remote to us now; to think that an entire generation has never seen it live.  Instead of moving forward, our moon-heart skipped a beat.
