Geologic Activity on Enceladous - Saturn's Moon

Recent studies from ESA and NASA's Cassini Mission revealed that one of the Saturn's moon Enceladus have Hydrothermal activity due to the heat from friction since billions of years. This discovery was made from new modelling study carried out by U.S researchers on NASA's Cassini Mission.

Team of researchers have published a paper on Hydrothermal activity and geologic activity of Saturn's moon Enceladous on 7 November 2017. Cassini found that Enceladous sprays water vapour and icy particles including organic in the south pole. Additional study revealed the existence of ocean beneath the crust and it venting water into space. Evidence from Cassini indicates the hydrothermal activity and the interaction of chemicals with rock which are taking place on the seafloor. The average thickness of ice beneath the crust is about 20 to 25 kilometers. Enceladous have water equals to 2% of Earth oceans. This oceans have frozen within 30 million years ago. The geologic activity of Enceladous is still a mystery. Further studies is going on Saturn's moon Enceladous.

Cassini Mission:

     The Cassini spacecraft was launched in 1997, it orbited Saturn from 2004 to 2017. Cassini made numerous dramatic discoveries, including the surprising activity on Enceladous and liquid methane on Saturn's largest moon, Titan. Cassini ended its journey with a dramatic plunge into the Saturn's atmosphere on 15th September 2017, returning science data until it lost contact with Earth.

     The Cassini-Huygens mission is a cooperative project of NASA, ESA and Italian Space Agency.NASA's Jet Propulsion Laboratory manages the mission for NASA's Science Mission Directorate, Washington. Cassini was designed and assembled by JPL.
