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?

I distinctly remember the National Geographic Magazine issue from 1981
which had an article on Voyager 1's mission to Saturn in late 1980 (but not Voyager 2's later flyby, which had not happened yet). Enceladus was rather far from Voyager 1 and no real surface features could be seen. This famous montage of the Saturn system includes the Voyager 1 image of the moon where you can see it is essentially blank: http://photojournal.jpl.nasa.gov/jpeg/PIA01482.jpg And Phil Stooke's more detailed maps and images: http://www.ssc.uwo.ca/geography/spacemap/enceladu.htm Scientists speculated that Enceladus' entire surface was constantly being covered and reshaped by active geysers. The article even included an artwork depicting these geysers spraying liquid water from cracks in the crust! Anyone else remember this or have the actual art handy to post? -------------------- "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 |
