Enceladus geysers "predicted" in 1981 National Geographic Magazine

ljk — 3/9/2006 11:13:45 PM (archived)

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:

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?

  - My guess is it's related to the high percentage of organic material in Comet Wild (n/t) - Buck Galaxy - 3/9/2006 5:33:32 PM
    - I am guessing Enceladus keep supplies Saturn's rings with icy material. (n/t) - REB - 3/9/2006 6:14:13 PM
      - rLooks like Enceladus is the source for the E-ring. - REB - 3/10/2006 7:49:01 PM

        Enceladus probably was much larger in the past... - REB - 3/9/2006 10:20:52 PM

        That is the main reason I think Enceladus is basically a large drop of water with an icy crust. - REB - 3/10/2006 1:07:48 PM
        
        Not a small core - Adam - 3/13/2006 9:33:30 PM
    - Looks like that's not it: NASA's Cassini spacecraft may have found evidence of liquid water reservoirs that erupt in Yellowstone-like geysers on Saturn's moon Enceladus. (n/t) - Buck Galaxy - 3/9/2006 5:45:44 PM
