Comments on: Cassini Pinpoints Source of Jets on Saturn's Moon Enceladus http://www.universetoday.com/2008/08/14/cassini-pinpoints-source-of-jets-on-saturns-moon-enceladus/ Space and astronomy news Sun, 22 Nov 2009 03:07:54 -0600 http://wordpress.org/?v=2.8.6 hourly 1 By: Hugh http://www.universetoday.com/2008/08/14/cassini-pinpoints-source-of-jets-on-saturns-moon-enceladus/comment-page-1/#comment-29648 Hugh Sat, 16 Aug 2008 07:29:24 +0000 http://www.universetoday.com/?p=16847#comment-29648 A question comes to mind; if the planet Mars over time lost it's oceans to space how come Enceladus with a much smaller mass can still be out gassing so much moisture? Is this a fairly new activity, or would this fuel some speculation that perhaps Enceladus was "recently" captured from an outer orbit.

Right on up there with Voyager. Cassini is a triumph. And still more to come! Yes! One of the top space achievements ever. Right on up there with Voyager. Cassini is a triumph.

On the original release the links point to a figure that makes the circles out as illustrating the uncertainty in location AFAIU; the actual outcome of a large series of measurements of jets (from 2007) are spread over a much larger area. (While I assume everyone expects them being associated with the sulci centers.) The news is, AFAIU, that the skeet shot imagined the earlier located and imaged areas once again. So as usual, a more confusing press release than not. On a more positive note, the previous NASA blog entry claims that at least one of the thermal imaging instruments also pinpointed the hot spot areas. I assume that they possibly can resolve the actual temperatures better with increased resolution. Now, <i>that</i> would be interesting news! Hmm.

It is singularly impressive not only for the technological feat of the imagining itself, but for the treasure-trove of science that they've just hit on. It is definitely one of the most important milestones of the Cassini mission so far, and to think - there are loads more fly-bys planned for this amazing little moon in the newly extended mission plan! Congrats Cassini team! Awesome. It is singularly impressive not only for the technological feat of the imagining itself, but for the treasure-trove of science that they've just hit on.
