Wassonite is an extremely rare titanium sulfide mineral with chemical formula TiS.[2][4] Its discovery was announced in a 2011 NASA press release as a single small grain within an enstatite chondrite meteorite called "Yamato 691", which was found during a 1969 Japanese expedition to Antarctica.[5] This grain represents the first observation in nature of the synthetic compound titanium(II) sulfide.
The mineral was named after John T. Wasson, a professor at the University of California, Los Angeles and was approved by the International Mineralogical Association.[6][7]
