In this article, we summarize the work of the NASA Outer Planets Assessment Group (OPAG)
Roadmaps to Ocean Worlds (ROW) group. The aim of this group is to assemble the scientific …

Water ice, abundant in the outer solar system, is volatile in the inner solar system. On the
largest airless bodies of the inner solar system (Mercury, the Moon, Ceres), water can be an …

The entry of the Cassini-Huygens spacecraft into orbit around Saturn in July 2004 marked
the start of a golden era in the exploration of Titan, Saturn's giant moon. During the Prime …

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 …

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 …

Ceres is the largest body in the asteroid belt with a radius of approximately 470 km. In part
due to its large mass, Ceres more closely approaches hydrostatic equilibrium than major …

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 …

INTRODUCTION Thermochemical models have predicted that the dwarf planet Ceres has,
to some extent, formed a mantle. Moreover, due to viscous relaxation, these models indicate …

INTRODUCTION Dwarf planet Ceres' low average-density (2162±3 kg m− 3) indicates that it
must contain considerable water. Water is likely a key component in the chemical evolution …

To better understand Earth's present tectonic style–plate tectonics–and how it may have
evolved from single plate (stagnant lid) tectonics, it is instructive to consider how common it …
