Delivery of dark material to Vesta via carbonaceous chondritic impacts

► Dark material on Vesta observed by Dawn is remnant carbonaceous chondrite impactor. ► Global abundance of carbonaceous chondrite material <6 vol.% similar to howardites. ► Distribution of dark material suggests delivery during Veneneia basin formation event. ► Suggests extensive volatile delivery onto Vesta by carbonaceous impactors. ► First direct link between HED meteorites and surface of Vesta.
