Ikapati crater on Ceres: potential past cryogenic activities and brine layer evolution Open
Ceres is the only dwarf planet of the inner Solar System, locater in the main asteroid belt as a mean solar distance of 2.8 AU. The DAWN spacecraft explored Ceres between 2015 and 2018. Its onboard Framing Camera (FC) and the reflectance S…

Ceres: Organic‐Rich Sites of Exogenic Origin? Open
Ceres, the largest object in the asteroid belt, is the only potential ocean world in the inner Solar System. Previous studies identified deposits of aliphatic organics in and around the Ernutet crater, and at small locations at Inamahari a…

New Candidates for Organic-rich Regions on Ceres Open
We explore the spatial distribution of organics on Ceres using the visible and near-infrared data collected by the Dawn mission. We employ a spectral mixture analysis (SMA) approach to map organic materials within the Ernutet crater at the…

Consus Crater on Ceres: Ammonium‐Enriched Brines in Exchange With Phyllosilicates? Open
Ceres is a partially differentiated dwarf planet located in the main asteroid belt. Consus crater (diameter ∼64 km) is one of the oldest impact features (∼450 Ma) on the Cerean surface that surprisingly still shows a large variety of color…

The Scientific Calibration of the Dawn Framing Camera Open
NASA’s Dawn mission visited the large main-belt asteroids Ceres and Vesta, returning a rich data set. Its science and navigation cameras, Framing Cameras 1 and 2, provided more than 100,000 surface images in total of both targets with seve…

The unique floor of Juling crater on Ceres Open
Results of NASA's Dawn mission indicate that Ceres, the biggest object in the main asteroid belt, may be geologically active because it shows changes in its morphology that might have happened in the last few geologic times. Juling is a ∼2…

Ceres—No further organic-rich sites: Implications for its evolution Open
Ceres—a potential ocean world—displays multiple signs of recent/current geological activity. There are indications of a high carbon content in its crust, but the exact form of this carbon is elusive. Spectral data acquired by NASA’s Dawn m…

Science Drivers for the Future Exploration of Ceres: From Solar System Evolution to Ocean World Science Open
Dawn revealed that Ceres is a compelling target whose exploration pertains to many science themes. Ceres is a large ice- and organic-rich body, potentially representative of the population of objects that brought water and organics to the …

Brine residues and organics in the Urvara basin on Ceres Open
Ceres is a partially differentiated dwarf planet, as confirmed by NASA’s Dawn mission. The Urvara basin (diameter ~170 km) is its third-largest impact feature, enabling insights into the cerean crust. Urvara’s geology and mineralogy sugges…

Habitability of Small Bodies — State of Knowledge and Motivations for Exploration in the Next Decade Open
This white paper addresses the following priority question identified by NASA's Small Bodies Assessment Group: Do sustainable habitable environments exist on any of the small bodies?This question is motivated by the results of the Dawn and…

Impact heat driven volatile redistribution at Occator crater on Ceres as a comparative planetary process Open
Hydrothermal processes in impact environments on water-rich bodies such as Mars and Earth are relevant to the origins of life. Dawn mapping of dwarf planet (1) Ceres has identified similar deposits within Occator crater. Here we show using…

GAUSS -- A Sample Return Mission to Ceres Open
The goal of Project GAUSS is to return samples from the dwarf planet Ceres. Ceres is the most accessible ocean world candidate and the largest reservoir of water in the inner solar system. It shows active cryovolcanism and hydrothermal act…

Unique Light Scattering at Occator's Faculae on (1) Ceres Open
The Occator crater on the dwarf planet Ceres is outstanding because of its relatively low age (∼22 Ma) and extremely young (≤4 Ma) and bright faculae on an otherwise mostly dark body (ratio of reflectances bright/dark >5). Knowledge of the…

Oxo Crater on (1) Ceres: Geological History and the Role of Water-ice Open
Dwarf planet Ceres (∅ ∼ 940 km) is the largest object in the main asteroid belt. Investigations suggest that Ceres is a thermally evolved, volatile-rich body with potential geological activity, a body that was never completely molten, but …
