Cassini detection of Enceladus' cold water‐group plume ionosphere

open access: yesGeophysical Research Letters, 2009
This study reports direct detection by the Cassini plasma spectrometer of freshly-produced water-group ions (O+, OH+, H2O+, H3O+) and heavier water dimer ions (HxO(2))(+) very close to Enceladus where the plasma begins to emerge from the plume.

Enceladus erupts

Physics Today, 2023
In the frozen reaches of the outer solar system, one Saturnian moon hosts rich geological activity, sustained by liquid water.

Under the Sea of Enceladus

Scientific American, 2016
The article reports on the availability of evidence that planet Saturn's moon Enceladus is harboring active hydrothermal vents, making it as one of the hottest places to look for life beyond Earth. Topics include the value of this hydrothermal activity as information on the composition and longevity of Enceladus' ocean, the need to learn how Enceladus ...

Activity of Enceladus and proto-Enceladus

2020
<p><strong>Introduction</strong>: Enceladus, a satellite of Saturn, is the smallest celestial body in the Solar System where endogenic activity is observed. Since its accretion, Enceladus has lost about 20% of its mass.  This is the base of hypothesis about proto-Enceladus [1, 2]. It means

The Restless World of Enceladus

Scientific American, 2008
When the Voyager 2 spacecraft sped through the Saturnian system more than a quarter of a century ago, it came within 90,000 kilometers of the moon Enceladus. Over the course of a few hours, its cameras returned a handful of images that confounded planetary scientists for years.

Hydrothermal processes on Enceladus

Science, 2017
Planetary Geology Saturn's moon Enceladus has a subsurface ocean covered by a layer of ice. Some liquid escapes into space through cracks in the ice, which is the source of one of Saturn's rings. In October 2015, the Cassini spacecraft flew directly through the plume of escaping material and sampled its chemical composition. Waite et al. found that the

The evolution of Enceladus

Icarus, 1983
Evidence is adduced for several episodes of geologic resurfacing and extensional tectonism spreading over much of the history of the small, icy Saturn moon Enceladus. Resurfacing was the product of fresh material eruptions that may have contained ammonia, which may also have made melting in the interior more likely.

Cryovolcanism on Enceladus

2021
Der kleine Saturnmond Enceladus ist eines der faszinierendsten und spannendsten Objekte in unserem Sonnensystem. Die NASA Raumsonde Cassini entdeckte beim Vorbeiflug eine anomale Zone erhöhter Temperatur in der Südpolarregion, und geysirartige Fontänen aus Wasserdampf und Wassereisteilchen (engl. "Plume"), die von Bruchlinien in der Südpolarregion, den

The Fountains of Enceladus

2010
Saturn has wealth of satellites. More than 60 are known by now, but only one of these, Titan, is larger than our Moon. Before the start of the Space Age, nine had been discovered. The rest are tiny and probably asteroidal.
