Er is water gevonden in oude maanmeteorieten

Apatiet is eerder geïdentificeerd in alle soorten gesteente op de maan, behalve in het oude ijzerhoudende anorthosiet, dat 4,5-4,3 miljard jaar geleden is gevormd en het enige bekende gesteentetype is dat rechtstreeks uit de maanmagma-oceaan is gevormd. Daarom werd gedacht dat er aanvankelijk weinig water aanwezig was op de vroege maan.

In het nieuwe werk identificeerden de wetenschappers de aanwezigheid van apatiet in ijzerhoudend anorthosiet in de maanmeteoriet Arabian Peninsula 007, die in 2015 in Saudi-Arabië werd ontdekt. Er werden dus veel vaker vluchtige stoffen aangetroffen in de maankorst dan de resultaten van eerdere onderzoeken suggereerden.
