Holy smokes, whose job is it going to be to assemble THIS mosaic? Is it you, Jason? Looks gnarly.

It's what I do, shouldn't be too difficult. It is just a clear filter mosaic.

That's gonna be a great set; lots of terra inexplorata, as it were.

Should we expect images worthy of the swear-jar this around?

I might have missed it in the mission description, but will Cassini be oriented dish-first along the trajectory during the plume flythrough? Not sure if they feel that any precautions are required or not.

Nope, the mass spectrometer and dust instruments will be facing forward to get the best possible sampling of the plume. We're confident by now that these passages are safe, especially as the speed of this passage is much slower than last time we flew through. The question we're anxious to learn about on this flyby (other than the science results of course) is whether the plume is affecting the spacecraft pointing stability enough to require use of the attitude control thrusters in future similar flybys. If we can get away without thrusters in future close plume flybys, we'll be able to use the flybys to measure gravity and thus investigate the interior structure under the tiger stripes, and we will plan on doing so next Spring, on orbit 131. If we have to continue to use thrusters in the plume we'll use the orbit 131 flyby for more plume sampling instead, because the thrusters interfere with the gravity measurements.

Thanks, John. I suspected as much given the emphasis on direct sampling; appreciate the reassuring confirmation!

I am sure I have missed this class...for when are we expecting the images of the flyby to hit the web?
