Video Transcript: Hydrogen Hot Spots on Vesta
The animation from NASA's Dawn mission shows
abundances of hydrogen in a wide swath around
the equator of the giant asteroid Vesta.
The hydrogen probably exists in the form of hydroxyl
or water bound to minerals in Vesta's surface.
Red indicates the greatest abundances of hydrogen and gray the lowest,
as measured by Dawn's gamma ray and neutron detector.
The hydrogen data were superimposed on a mosaic of
images and 3-D model of Vesta created from
Dawn framing camera data.
