Seven keys to understanding the overflight of Enceladus











For the first time Cassini probe (NASA) will fly over the inside of a cryomagmatic pen. It will be in Enceladus and analyzing it will show us in detail the composition of the global ocean of this satellite of Saturn. The sorefuelo will be tomorrow, but before, I leave you seven key points to understand this maneuver:

1) Cassini has discovered a remarkable geological activity in Enceladus among which are these feathers formed by ice, water vapor and organic molecules from their internal global ocean.







2) This overflight will be Cassini's deepest intrusion through the cryomagmatic feathers of Enceladus.







3) The overflight does not intend to detect life, but it does provide new knowledge about how habitable the internal ocean of Enceladus is.







4) It is intended to obtain information on the amount of hydrothermal activity that is occurring inside Encelado, which could have important implications for the potential habitability of the ocean in terms of sustaining simple life forms.







5) It is expected to better understand the chemistry of the ejected materials. With the low height of the flyby we want to detect the heavier molecules, including organic matter.







6) The maneuver will help resolve the question of whether the pen is a column, a curtain, an accumulation of smaller pens or a mixture of all of the above. Knowing its morphology will know how the material travels from the ocean to the surface.







7) The ability to quantify the amount of material that has been poured into space would give a clue as to how long Enceladus could have been active.









Tomorrow is the flyby. We will see how it takes place and the clues it offers to better understand this world full of questions.
