Pluto, surfaceCharonSpectroscopySatellites, compositionThe surface of Pluto as it is understood on the eve of the encounter of the New Horizons spacecraft (mid-2015) consists of a spatially heterogeneous mix of solid N2, CH4, CO, C2H6, and an additional component that imparts color, and may ...
The dark polar region on Charon, informally nicknamed Mordor, is one of its most intriguing features. There is also a gigantic stretch of cliffs and troughs running for 600 miles across the moon, and deep canyons elsewhere. In the southern regions, smoother terrain reveals that Charon...
The surface of Pluto as it is understood on the eve of the encounter of the New Horizons spacecraft (mid-2015) consists of a spatially heterogeneous mix of solid N2, CH4, CO, C2H6, and an additional component that imparts color, and may not be an ice. The known molecular ices are de...
They were expected to encounter Pluto near its perihelion, before its atmosphere froze once again, a seasonal deep freeze that lasts more than 100 years. The spacecraft were to study the atmosphere, surface features, and geologic composition of Pluto and Charon, then fly by Pluto into the ...

We have modeled the spectrum of May 15 that corresponds to the maximum of Pluto's visible lightcurve using a radiative transfer algorithm dealing with compact and stratified media. A geographical mixture of three distinct units is required to explain all the significant structures of the analyzed ...

Learning more about the composition of Pluto's moon could potentially provide insight into Charon's neighbors in the Kuiper Belt, the researchers said. The belt region encompasses the other rings of the solar system, beyond Neptune's orbit, and is home to icy objects like dwarf...
