Understanding the mechanism of the water ice vaporization on Ceres

Editor’s Highlight—

 

The presence of water vapor around Ceres, a dwarf planet within the orbit of Neptune, is a current research topic of high interest. This paper explores the link between two interesting observations: the Kuppers et al. [2014] detection of water vapor around Ceres and the Dawn mission GRaND instrument’s detection of exposed water ice on the surface. The authors argue that a global ice table cannot simultaneously explain both these observations. Their conclusion, that any exposed water ice able to explain the Kuppers et al. result should no longer be observable from Dawn today, is important both scientifically and for mission planning. These results should be of general interest to the planetary science community.
