Cassini flyby of plume
The data gathered by Cassini in her final flybys in October (E21) and December 2015 (E22) are expected to yield some clues regarding the chemistry of the moon's ocean and prospects for some form of biochemistry. The data may not be published until December 2016, it seems....
- Cassini did a final flyby of Enceladus in late October that targeted the chemistry of the plumes directly. The INMS team, which includes Glein, is searching for molecular hydrogen in that plume, which would be chemical evidence of active serpentinization. An absence of molecular hydrogen would be a sign that the serpentinization is extinct. The data analysis from this flyby may be completed in time for the American Geophysical Union's fall meeting in December. Glein added that the planned NASA mission to Europa includes advanced descendants of both the CDA and INMS instruments, meaning that in a decade or two, scientists can start to make these same measurements at Europa. This will allow us to better understand the importance of serpentinization across the Solar System.

"Le sauce"
I am aware I had not provided any source for the array of images, as pointed out by @ZergTwo. In hindsight, it is indeed unwise to provide image with no verification as it may be misleading.
For the moons of Saturn, I used [1]. Due to the existence of shadows, I took the smallest ("height") value and scaled the image of Mimas, Enceladus etc according to it, which unfortunately may induce errors of perhaps up to 3 pixels (6km, rough estimate). In contrast, for Hyperion, I assumed the the object is viewed pole-on from axis c and scaled according to the longest ("length") value. While the errors are non-negligible (~1.5% for Mimas, rough estimate), it has significantly less errors compared to the single pixel both Enceladus and Hyperion (examples) occupy on the "preview", which give the impression of both objects being the same size.
I hope this provides clarity and prevents further misunderstanding. I apologize for the mistake. Pancakes321 (talk) 00:57, 13 May 2025 (UTC)
