Meer water op de Maan dan aanvankelijk gedacht

Nominally hydrous magmatism on the Moon

For the past 40 years, the Moon has been described as nearly devoid of indigenous water; however, evidence for water both on the lunar surface and within the lunar interior have recently emerged, calling into question this long-standing lunar dogma. In the present study, hydroxyl (as well as fluoride and chloride) was analyzed by secondary ion mass spectrometry in apatite [Ca5(PO4)3(F,Cl,OH)] from three different lunar samples in order to obtain quantitative constraints on the abundance of water in the lunar interior. This work confirms that hundreds to thousands of ppm water (of the structural form hydroxyl) is present in apatite from the Moon.

En dat terwijl Robert Zubrin in "Entering Space" beweerde dat er zo weinig water op de maan is, dat je bereid zou zijn het water uit beton terug te winnen om daar een kpje thee te zetten.
