NASA’s Cassini Observes Interaction of Titan with Supersonic Solar Wind

This image shows conditions observed by Cassini during a flyby on December 1, 2013, when the magnetosphere of Saturn was highly compressed, exposing Titan to the full force of the solar wind. In analyzing data from the encounter, the researchers observed that the moon interacted with the solar wind much like the planets Mars and Venus, or a comet. Specifically, they saw that the solar wind draped itself around Titan, creating a shockwave that formed around Titan where the full-force solar wind rammed into the atmosphere of the moon. Previously, scientists had thought Titan would have a different sort of interaction with the solar wind because of the complex atmospheric chemistry of the moon. Image credit: NASA / JPL-Caltech.

Scientists analyzing data from NASA’s Cassini spacecraft have found that Titan – the largest moon of Saturn and the only moon in the Solar System with a dense atmosphere – behaves much like Venus, Mars or a comet when exposed to the superfast solar wind. This image shows conditions observed by Cassini during a flyby on December 1, 2013, when the magnetosphere of Saturn was highly compressed, exposing Titan to the full force of the solar...

The Nili Fossae system, part of which is shown in this image, is an area of great geological interest near the giant Isidis impact basin, northeast of the Syrtis Major volcanic province. The system contains numerous troughs, one of which can be seen crossing the lower left of this image. On the plateau above, several depressions can be seen, some of them extending into the trough. A large, 55 km-diameter impact crater with a central pit can be seen on the right. This image was acquired by the High Resolution Stereo Camera on the Mars Express on 16 October 2014. North is to the right, east is up. Image credit: ESA / DLR / FU Berlin / CC BY-SA 3.0 IGO.

This is an artist's concept of NASA's New Horizons during its planned encounter with Pluto and its moon, Charon: the craft's miniature cameras, radio science experiment, ultraviolet and infrared spectrometers and space plasma experiments would characterize the global geology and geomorphology of Pluto and Charon, map their surface compositions and temperatures, and examine Pluto's atmosphere in detail; the spacecraft's most prominent design feature is a nearly 2.1-m dish antenna, through which it would communicate with Earth from as far as 7.5 billion km away.
