Geophysics of the Pitman Fracture Zone and Pacific-Antarctic Plate Motions During the Cenozoic
Multibeam bathymetry and magnetometer data from the Pitman fracture zone (FZ) permit construction of a plate motion history for the South Pacific over the past 65 million years. Reconstructions showExpand

Ammoniated phyllosilicates with a likely outer Solar System origin on (1) Ceres
Studies of the dwarf planet (1) Ceres using ground-based and orbiting telescopes have concluded that its closest meteoritic analogues are the volatile-rich CI and CM carbonaceous chondrites. Water inExpand

The Geologically Recent Giant Impact Basins at Vesta’s South Pole
A New Dawn Since 17 July 2011, NASA's spacecraft Dawn has been orbiting the asteroid Vesta—the second most massive and the third largest asteroid in the solar system (see the cover). Russell et al.Expand

Dawn Mission to Vesta and Ceres
The initial exploration of any planetary object requires a careful mission design guided by our knowledge of that object as gained by terrestrial observers. This process is very evident in theExpand

Dawn arrives at Ceres: Exploration of a small, volatile-rich world
On 6 March 2015, Dawn arrived at Ceres to find a dark, desiccated surface punctuated by small, bright areas. Parts of Ceres’ surface are heavily cratered, but the largest expected craters are absent.Expand

Bright carbonate deposits as evidence of aqueous alteration on (1) Ceres
The typically dark surface of the dwarf planet Ceres is punctuated by areas of much higher albedo, most prominently in the Occator crater. These small bright areas have been tentatively interpretedExpand

Dawn; the Vesta–HED connection; and the geologic context for eucrites, diogenites, and howardites
The Dawn mission has provided new evidence strengthening the identification of asteroid Vesta as the parent body of the howardite, eucrite, and diogenite (HED) meteorites. The evidence includesExpand

Dawn completes its mission at 4 Vesta
The Dawn mission was designed to test our hypothesis about the origin and evolution of the early solar system by visiting the largest differentiated basaltic asteroid, 4 Vesta, believed to be aExpand

Extensive water ice within Ceres’ aqueously altered regolith: Evidence from nuclear spectroscopy
Water ice beneath the surface of Ceres The dwarf planet Ceres in the inner solar system is thought to have a crust made of a mixture of rock and ice. Prettyman et al. used neutron and gamma-rayExpand

A partially differentiated interior for (1) Ceres deduced from its gravity field and shape
Remote observations of the asteroid (1) Ceres from ground- and space-based telescopes have provided its approximate density and shape, leading to a range of models for the interior of Ceres, fromExpand
