JIRAM is an imager/spectrometer on board the Juno spacecraft bound for a polar orbit
around Jupiter. JIRAM is composed of IR imager and spectrometer channels. Its scientific …

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 …

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 …

The Dawn mission journeys to the center of the main asteroid belt to orbit and explore the
two most massive main belt asteroids, Vesta and Ceres. Dawn aims to increase our …

Organic compounds occur in some chondritic meteorites, and their signatures on solar
system bodies have been sought for decades. Spectral signatures of organics have not …

We present an experimental study on ion irradiation of carbonaceous chondrites, simulating
solar wind irradiation on primitive asteroids, to better constrain the space weathering …

INTRODUCTION The surface of the dwarf planet Ceres is known to host phyllosilicate
minerals, but their distribution and origin have not previously been determined …

The surface and internal structure of Ceres show evidence of a global process of aqueous
alteration, indicating the existence of an ocean in the past. However, it is not clear whether …

Vesta's surface is characterized by abundant impact craters, some with preserved ejecta
blankets, large troughs extending around the equatorial region, enigmatic dark material, and …

Vesta is a large differentiated rocky body in the main asteroid belt that accreted within the
first few million years after the formation of the earliest solar system solids. The Dawn …
