Abstract The NASA Dawn Mission will determine the surface composition of 4 Vesta and 1
Ceres, providing constraints on their formation and thermal evolution. The payload includes …

Inspired by the recent results of the Dawn mission, thermodynamic models of rock alteration
and brine evaporation have been used to help understand the conditions under which water …

The surface mineralogy of dwarf planet Ceres appears to be dominated by products of rock–
fluid interactions, such as phyllosilicates—some of which are NH4-bearing—and …

Ceres, the most water-rich body in the inner solar system after Earth, has recently been
recognized to have astrobiological importance. Chemical and physical measurements …

Abstract The Psyche mission's Oxidation-Reduction Working Group is focused on
understanding, determining, and applying the redox state of (16) Psyche to understand the …

Asteroids were likely a major source of volatiles and water to early Earth. Quantifying the
hydration of asteroids is necessary to constrain models of the formation and evolution of the …

As the Dawn mission approaches a successful conclusion at Ceres, it seems time to assess
how its findings have sharpened the picture of Ceres's evolution. Before Dawn, we inferred …

The ingredients to make an environment habitable (eg, liquid water, chemical disequilibria,
and organic molecules) are found throughout the solar system. Liquid water has existed …

The cosmochemistry of meteorites provides unique clues on asteroids accretion,
differentiation, collisional break-up and reassembly-processes of critical importance for …

Results of Ceres' exploration with the Dawn spacecraft are modeled and discussed in terms
of rock/organic/elemental composition, density and porosity in the interior, and formation …
