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?

Does anyone have further info about the composition of the dark green organic material seen streaked on the icy surface, as mentioned in the "Tiger, Tiger Burning Bright" article? Would this have come from the plumes presumably?

I think the author misinterpreted the results from ISS and VIMS. The greenish color of the tiger stripes doesn't come from the simple organics VIMS found, but from the coarse-grained, crystalline water ice found there. We are still working on whether the greenish color comes from plume deposits, thermally altered water ice, or magmatically-emplaced ice.

I noticed that one of the papers linked to from the article, the abstract for it, mentions "light organics" found on the surface. Now I'm not sure again; are the "dark green streaks of organic material" in the article referring only to the tiger stripes or are there other streaks also? I had only heard of the tiger stripes though, with the bluish colouring from the ice deposits. Are the simple organics on the surface, in the plumes or both? I had thought they were in the plumes. Somebody in another forum is adamant that the dark green organic streaks, as described in the article, are there, and that you are completely wrong (I had mentioned your clarification, that the article was mistaken, but he isn't buying it)... wink.gif
