Enceladus just jumped to way near the top of the list of biologically interesting places. We know how to get to Mars; we some ideas of further exploration of Euiropa and Titan. Has anyone designed a mission to land on Enceladus? What would it take? How much delta vee?

* Encore For Enceladus! Saturn Moon Ripe For Astrobiology Exploration

http://www.space.com/scienceastronomy/0604...ery_monday.html

The discovery of apparent liquid water reservoirs erupting in Yellowstone-like
geysers on Saturn's moon Enceladus has produced a gusher of questions.

I sympathize with Griffin, but do not agree with the way the choices are being
implemented.


--------------------
"After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance.
I see that such intercourse long continued would make one thoroughly prosaic, hard,
and coarse. But the longest intercourse with Nature, though in her rudest moods, does
not thus harden and make coarse. A hard, sensible man whom we liken to a rock is
indeed much harder than a rock. From hard, coarse, insensible men with whom I have
no sympathy, I go to commune with the rocks, whose hearts are comparatively soft."

- Henry David Thoreau, November 15, 1853

QUOTE (Space.com)
In short, Porco said, "Cassini is so very well equipped, that it could be the precursor mission for a future landed mission to the south pole of Enceladus. In other words, we could do in the next few years with Cassini at Enceladus what the next orbiter of Jupiter would do at Europa."


It sounds like they - Carolyn, is/are so worried about extended mission funding, they are arguing the Cassini/extended should be funded, if necessary, at the the expense of the Europa mission huh.gif
