In a new study published in Nature Geoscience today, researchers used a three-dimensional climate model of Titan's atmosphere together with an analysis of dune locations and measurements from the Voyager 1 spacecraft, the Cassini orbiter and the Huygens probe to discover how the moon's lowermost atmosphere interacts with its surface.

Saturn's largest moon, Titan, is an intriguing, alien world that's covered in a thick atmosphere with abundant methane. With an average surface temperature of a brisk -297 degrees Fahrenheit (about 90 kelvins) and a diameter just less than half of...

AVIATR is Barnes’s concept for an aerial drone powered by two small nuclear generators (known as Advanced Stirling Radioisotope Generators, or ASRGs) that could stay airborne over Titan pretty much indefinitely. The ASRGs together would only provide about 250 watts, or enough to power two light bulbs. But Titan makes flying easy and non-energy-intensive--it exerts seven times less gravity than Earth and hosts an atmosphere that’s three times denser.

Peaking under the thick atmosphere using Cassini's Visual and Infrared Mapping Spectrometer, an international team has composed a global color map of Titan. This mosaic was compiled from imagery taken over seventy flybys of Saturn's largest moon.
