Enceladus: Getting Very Near the End II Posters

Submit an Abstract to this Session Please know the abstract submission deadline has passed. There are no exceptions to this deadline and no new abstracts can be submitted.
You can still search the program to see your colleague�s abstract submissions as well as the sessions submitted for the 2016 Fall Meeting. The final program will be released in early October.


Session ID#: 12393

Session Description:
Though the very close targeted flybys of Enceladus by the Cassini spacecraft at Saturn -- 22 of them in all -- came to an end in December 2015, Cassini's more distant remote-sensing observations of Enceladus did not.  These in fact will continue up to the mission's finale, slated to occur no later than September 15, 2017.  Consequently, this special AGU session on Enceladus, the 11th in a row, will be the last one to occur while Cassini is still active at Saturn.

As in years past, we will focus on the most recent observational, theoretical and modeling efforts aimed at assessing the moon's ocean chemistry, the characteristics and hydrodynamics of its geysers, the moon's dynamical and rotational states, its thermal and interior structure and evolution, its geological history, as well as its astrobiological potential.  Presentations on concepts for future missions back to Enceladus will also be considered.
