The images taken from the lower-than-ever orbit brought the crater into sharper focus, particularly the deposit called Cerealia Facula near its center.
The facula diagram shows the magnitude of each light vector on the image plane, as shown in Figure 8.
The spots, forming a bright area called Cerealia Facula at Occator's center and a complex of secondary spots, collectively called Vinalia Faculae, on its eastern floor, appear to be deposits of carbonate-rich salts--residue from briny flows that gurgled up from a fluid reservoir (perhaps a global ocean) deep in the asteroid's interior.
