Yes, it was worth the five minutes.  Cool stuff.
If there really was intelligent life on other planets, we'd be sending them foreign aid.

Conservatives see George Orwell's "1984" as a cautionary tale.  Progressives view it as a "how to" manual.

My wife often says to me, "You are evil and must be destroyed." She may be right.

Liberals believe one should never let reason, logic and facts get in the way of a good emotional argument.

That was cool. For me, the hexagonal storm especially so. Not just in trying to contemplate its size, but its shape as well. Maybe it is controlled by the great machine. :)

PBS has been running this for a couple of days now:

http://www.pbs.org/wgbh/nova/space/death-dive-to-Saturn.html (53:10)

An hour-long NOVA special with much more.   Much sadness in the ground crew, which has been working with the probe practically since it was launched.

Ben's interested in the Hexagonal storm (I am, too), but I wondered about the little "propeller planets" (moons, actually) trying to form in the rings:

https://www.space.com/8731-giant-propellers-discovered-saturn-rings.html

Apparently, gobs of the ring particles are trying to accrete, and this may provide a picture of why the solar system is the way it is.

I would want my ashes to be on board....
Some days even my lucky rocketship underpants won't help.


Bring me my Broadsword and a clear understanding.
Get up to the roundhouse on the cliff-top standing.
Take women and children and bed them down.
Bless with a hard heart those that stand with me.
Bless the women and children who firm our hands.
Put our backs to the north wind.
Hold fast by the river.
Sweet memories to drive us on,
for the motherland.

Last I heard, each one could still generate about a horsepower each.

PS.  Horsepower, just to note how far we've come since:

Quote
The term was adopted in the late 18th century by Scottish engineer James Watt to compare the output of steam engines with the power of draft horses. It was later expanded to include the output power of other types of piston engines, as well as turbines, electric motors and other machinery. :D

Space X and Blue Origin have a new marketing opportunity.

Imagine your ashes burning up over Saturn or Jupiter. Yeah, it will take a few years, but what's the rush? You're already dead.
I wish the Ring had never come to me. I wish none of this had happened.

So do all who live to see such times. But that is not for them to decide. All we have to decide is what to do with the time that is given to us. There are other forces at work in this world, Frodo, besides the will of evil. Bilbo was meant to find the Ring. In which case, you also were meant to have it. And that is an encouraging thought

Yeah, 35kg of pretty much spent plutonium over a planet that big.

Proofreader's / editor's eyeballs waking up this AM:

Why did they call it "re-entry" into Saturn?

How do you "burn up" your ashes?

I suppose the lefty anti nuke  crowd is still angry about the nuclear powered Cassini.   What a silly squabble that was.

Well, there have been "incidents" with these power supplies --enough to keep us on our toes, I guess.

One in particular was "amusing" in a "man proposes, G-d disposes" sort of way:

Quote


One RTG [Radioisotope Thermoelectric Generator], the SNAP-19C, was lost near the top of Nanda Devi mountain in India in 1965.  It was stored in a rock formation near the top of the mountain in the face of a snowstorm before it could be installed. It was supposed to power a CIA automated station for collecting telemetry from a Chinese rocket testing facility.

The seven capsules[34] were carried down the mountain onto a glacier by an avalanche and never recovered.

It is most likely that they melted through the glacier and were pulverized, whereupon the 238 plutonium - zirconium alloy fuel oxidized [ "and mixed with ?"] soil particles which are now apparently moving in a plume under the glacier.

(Extensively edited by 230RN for clarity. See original):

https://en.wikipedia.org/wiki/Radioisotope_thermoelectric_generator#Radioactive_contamination


Or maybe that should be, "CIA proposes, China disposes."

It's hard to believe the Chinese were not well-aware of this project, and, you know, it's not all that difficult to start an avalanche all innocent-like.  :D

Given how much radiation Saturn generates all on its own, plus the fact that there's no actual land masses on Saturn, no one is ever going to have to worry about that Plutonium.
