P33D:
Ceres and Vesta: Understanding the Protoplanets of the Asteroid Belt II Posters


Submit an Abstract to this Session


Session ID#: 48891

Session Description:
Many of the outstanding questions about Vesta and Ceres have been addressed by analyzing data from the Dawn mission. A comprehensive mapping campaign was undertaken at both bodies, as well as studies of their compositions, geophysical properties, and interiors, which enabled new understanding of their place in the history of our Solar System. Although, prior to Dawn, thought to be currently geologically inactive, with surfaces modified primarily by impacts, there is evidence for magmatic activity on Vesta, cryovolcanism on Ceres, and tectonic processes on both. Dawn’s second extended mission from the planned 35-km pericenter altitude orbit promises new observations by the time of the meeting that will enable characterization of Ceres at unprecedented resolution.

We encourage abstract submissions related to geologic, geophysical, spectroscopic and compositional analyses of Ceres and Vesta. Possible topics include analyses of Dawn data, telescopic observations, modeling and laboratory experiments. Comparative analyses with other bodies are welcome.
