Research Abstract |
We have investigated chemical reactions between primordial volatiles(such as ammonia and carbon dioxide) and primitive minerals(such as olivine) in Enceladus' interior ocean by conducting laboratory experiments of hydrothermal reactions. By comparing the results with the observations of Enceladus' plume by the Cassini spacecraft, we have discussed the temperature conditions of possible hydrothermal systems and habitability in Enceladus' ocean.
