Iron whiskers on asteroid Itokawa indicate sulfide destruction by space weathering
The authors here investigate troilite (FeS) grains recovered from the regolith of asteroid Itokawa. Finding wide-spread occurrence of metallic iron whiskers, the authors suggest them to be a decomposition product formed through irradiation of the sulfide by energetic ions of the solar wind.
