PIA22478: Vinalia Faculae Up Close

Vinalia Faculae Up Close


This close-up image of the Vinalia Faculae in Occator Crater was obtained by NASA's Dawn spacecraft on June 14, 2018 from an altitude of about 24 miles (39 kilometers).

This image reveals the intricate pattern between bright and dark material across this flow feature. The complex structure of the dark background is reminiscent of lava flows observed on Earth. However, in the case of Ceres, the flow material likely involved a lot of ice. The bright material is mostly composed of sodium carbonate, a salt whose exposure onto the crater floor involved a liquid source.

The center of this picture is located at about 21.0 degrees north latitude and 241.3 degrees east longitude.
