Ok…. April fool but maybe not totally. I love the DSOTM and as most of you know it is mostly made of the super hard ceramic ZrO2 (Zirconium Oxide). Well I am no geologist but anyone looking at the moon can tell that any research will involve a lot of rocks. The moon shares a lot of materials with the earth and even Tranquillityite was eventually found in Australia (which is very similar to the moon in many ways apparently :0). The materials have been through different processes and of course are more exposed to the harsh conditions of space so there are differences in composition and concentrations.
Looking at the science reports for the various missions there was a lot of interest in the large amounts of Zirconium and baddereleyite (a rare zirconium oxide mineral which is the naturally occurring form of ZrO2 (Zirconium Oxide). It turns out Zirconium is one of the commonest of the Moons minor metals with Baddeleyite (Zirconium Oxide ZrO2) being one of the most widespread. It makes me see my DSOTM in a whole new light……It Moon rocks in more ways than one….
