We present a coupled reorientation and climate model, to understand how true polar wander (TPW) and atmospheric condensation worked together to create the Sputnik Planitia (SP) ice sheet and reorient it to its present-day location on Pluto. SP is located at 18°N, 178°E, very close to the anti-Charon point, and it has been previously shown that this location can be explained by TPW reorientation of an impact basin as it fills with N2 ice. We readdress that hypothesis while including a more… Expand


The rapid formation of Sputnik Planitia early in Pluto’s history
Modelling suggests that Sputnik Planitia formed shortly after Charon did and has been stable, albeit gradually losing volume, over the age of the Solar System. Expand
Reorientation of Sputnik Planitia implies a subsurface ocean on Pluto
It is argued that if Sputnik Planitia did indeed form as a result of an impact and if Pluto possesses a subsurface ocean, the required positive gravity anomaly would naturally result because of shell thinning and ocean uplift, followed by later modest nitrogen deposition. Expand
Observed glacier and volatile distribution on Pluto from atmosphere–topography processes
The model predicts N2 ice accumulation in the deepest low-latitude basin and the threefold increase in atmospheric pressure that has been observed to occur since 1988, and points to atmospheric–topographic processes as the origin of Sputnik Planitia’s N2 glacier. Expand
Reorientation and faulting of Pluto due to volatile loading within Sputnik Planitia
It is reported that the location of Sputnik Planitia is the natural consequence of the sequestration of volatile ices within the basin and the resulting reorientation (true polar wander) of Pluto. Expand
Geological mapping of Sputnik Planitia on Pluto
Abstract The geology and stratigraphy of the feature on Pluto informally named Sputnik Planitia is documented through geologic mapping at 1:2,000,000 scale. All units that have been mapped areExpand
Formation of the Sputnik Planum basin and the thickness of Pluto's subsurface ocean
We simulate the formation of the large elliptical impact basin associated with Pluto's Sputnik Planum (SP; informal name). The location of SP suggests that it represents a large positive massExpand
The nitrogen cycles on Pluto over seasonal and astronomical timescales
Abstract Pluto’s landscape is shaped by the endless condensation and sublimation cycles of the volatile ices covering its surface. In particular, the Sputnik Planitia ice sheet, which is thought toExpand
Primordial N2 provides a cosmochemical explanation for the existence of Sputnik Planitia, Pluto
Abstract The presence of N2 in the surface environment of Pluto is critical in creating Pluto's richness of features and processes. Here, we propose that the nitrogen atoms in the N2 observed onExpand
The geology of Pluto and Charon through the eyes of New Horizons
Nasa’s New Horizons spacecraft has revealed a complex geology of Pluto and Charon, including evidence of tectonics, glacial flow, and possible cryovolcanoes, and these findings massively increase the understanding of the bodies in the outer solar system. Expand
Long-term surface temperature modeling of Pluto
Abstract NASA’s New Horizons’ reconnaissance of the Pluto system has revealed at high resolution the striking albedo contrasts from polar to equatorial latitudes on Pluto, as well as the sharpness ofExpand
