Could It Be Snowing Microbes on Enceladus? Assessing Conditions in Its Plume and Implications for Future Missions
We analyzed Cassini Imaging Science Subsystem (ISS) images of the plume of Enceladus to derive particle number densities for the purpose of comparing our results with those obtained from other Cassini instrument investigations. Initial discrepancies in the results from different instruments, as large as factors of 10-20, can be reduced to ∼2 to 3 by accounting for the different times and geomet...
متن کاملEnceladus' water vapor plume.
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. This plume provides an adequate amount of water to resupply losses from Saturn's E rin...
متن کاملAssessing primary care in Croatia: could it be moved forward?

Is Enceladus’ plume tidally controlled?
[1] Explanations for the plume of gas, water vapor and ice particles jetting from rifts in Enceladus’ south polar region include boiling of liquid water and dissociation of clathrate hydrates. In either case, production of the plume may be quasi-static or tidally controlled, with implications for the interior structure and composition of Enceladus. Previous quantification of the clathrate expla...
