On March 27, 2012, the Cassini space proble passed at a height of just 74 km (46 miles) from the south pole of Enceladus. In this way, the probe has been able to use its Ion and Neutral Mass Spectrometer (INMS) and its Plasma Spectrometer (CAPS) to analyze the particles of the jets coming from this satellite. It was found that these jets contain organic materials and salts with a salinity level very similar to the Earth’s oceans.
