Random Ramblings

From the Bent of Tau Beta Pi (http://www.tbp.org/pages/publications/BENTFeatures/Su06Bell.pdf) ... did you know that dust is one of NASA's top concerns with a permanent presence on the Moon (or Mars)??!?!?!

Seems kinda strange, but it turns out that moon-dust isn't the stuff that poets and songwriters would have us believe. Whereas dust on Earth tends to be organic (and hence soft), moon-dust tends to be shards of rock and powdered glass with lots of jagged edges and sharp points ... a very effective abrasive! They say wiping one's visor is enough to scratch the protective gold layer.
