Cryovolcanism on Ceres.
Volcanic edifices are abundant on rocky bodies of the inner solar system. In the cold outer solar system, volcanism can occur on solid bodies with a water-ice shell, but derived cryovolcanic constructs have proved elusive. We report the discovery, using Dawn Framing Camera images, of a landform on dwarf planet Ceres that we argue represents a viscous cryovolcanic dome. Parent material of the cr...
متن کاملGeochemistry, Thermal Evolution, and Cryovolcanism on Ceres with a Muddy Ice Mantle
Introduction: Interpretation of data acquired at Ceres by the Dawn spacecraft demands a model for the evolution of Ceres’ structure and composition to date. In a recent paper [1], we presented such a model, consistent with pre-Dawn observations and preliminary data returned by Dawn. Here, we describe this model, compare its physico-chemical outcomes to reported observations, and outline possibl...
متن کاملCryovolcanism and the Recent Flow of Liquid Water on Mars
The surface of Mars is too cold and dry to permit stable liquid water, yet fresh, apparently water-carved gullies and seepage features have been identified in high-resolution imaging of canyon and crater walls by the Mars Global Surveyor spacecraft. Here, a model of nonequilibrium hydrological activity and liquid water cryovolcanism explains the paradoxical appearance and observed properties of...
متن کاملCratering on Ceres: Implications for its crust and evolution.
Thermochemical models have predicted that Ceres, is to some extent, differentiated and should have an icy crust with few or no impact craters. We present observations by the Dawn spacecraft that reveal a heavily cratered surface, a heterogeneous crater distribution, and an apparent absence of large craters. The morphology of some impact craters is consistent with ice in the subsurface, which mi...
