The pH of Enceladus’ ocean [PDF]
Geochimica Et Cosmochimica Acta, 2015 Observational data from the Cassini spacecraft are used to obtain a chemical model of ocean water on Enceladus. The model indicates that Enceladus' ocean is a Na-Cl-CO3 solution with an alkaline pH of ~11-12. The dominance of aqueous NaCl is a feature that Enceladus' ocean shares with terrestrial seawater, but the ubiquity of dissolved Na2CO3 suggests ...

Ongoing hydrothermal activities within Enceladus
Nature, 2015Detection of sodium-salt-rich ice grains emitted from the plume of the Saturnian moon Enceladus suggests that the grains formed as frozen droplets from a liquid water reservoir that is, or has been, in contact with rock. Gravitational field measurements suggest a regional south polar subsurface ocean of about 10 kilometres thickness located beneath an ...

Science, 2006
The Cassini spacecraft flew close to Saturn's small moon Enceladus three times in 2005. Cassini's UltraViolet Imaging Spectrograph observed stellar occultations on two flybys and confirmed the existence, composition, and regionally confined nature of a water vapor plume in the south polar region of 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.&#160; This is the base of hypothesis about proto-Enceladus [1, 2]. It means

Hydrothermal processes on Enceladus
Science, 2017Planetary 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

Icarus, 2015
Abstract Despite its small size, Enceladus emits considerable heat, especially at its south pole, even long after simple thermal models predict it should be frozen. Several sources of energy have been proposed as responsible for this heating, such as tidal dissipative heating (TDH), convection and shearing in the ice shell, and exothermic chemical ...

Radioisotope power system-based enceladus smallsat mission concept: Enceladus express
2017 IEEE Aerospace Conference, 2017The coming decades of planetary science and deep space exploration will likely have a combination of more ambitious missions and ever more constrained budgets. The outer solar system, in particular, poses a challenge for lower mission cost as the principal need for a robotic craft — a source of energy — is difficult to supply through conventional means
