Nephilimfree already said something similar, about our Moon. When the fountains of the deep broke open, they were so powerful that the water achieved escape velocity and sprayed out into space, causing the craters on the Moon. It was christened the Lunar Bukkake theory.
At the age of five, Skagra decided emphatically that God did not exist. This revelation tends to make most people in the universe who have it react in one of two ways - with relief or with despair. Only Skagra responded to it by thinking, 'Wait a second. That means there's a situation vacant.'

I think variation of orbit and exposure to the sun should create thermodynamic processes that allow pressure inside to erupt. It is always good to have data from those probes humans have strived to build, just to know a little bit more out of this erhm, big universe?

Of course it is, it was a serious question, but what you say makes sense of course. Very exciting.

Having reservoirs of water that erupts to the surface from time to time does not imply the reservoirs are so large that it separates the entire crust of the moon from solid contact with the core, and act as a decoupled shell floating on a libricated layer of water.
This discovery shows that in fact is the case.

Enceladus was seriously considered as a target for manned mission back in the good old days of the Orion Nuclear Impulse space ships.
It would have been glorious, sigh.
The granting of a pardon is an imputation of guilt, and the acceptance a confession of it.

Well yeah, at least where "easier" is substantially a proxy for "faster", especially considering that it's likely a mission to Saturn is going to involve a gravity assist from Jupiter.
Then again, why do one, when you can do both for (at least) twice the price?

And yet, people survived that.
Uh huh.

It's not quite as simple as "swinging past" Jupiter to get into a Saturn orbit; they have to both be in such a position (and in a position relative to Earth) that we can utilize the technique. It limits available launch windows to wait, whereas Jupiter is always just a matter of what time of year, so the Earth is in the right position relative to Jupiter.
Also, every kilogram of that satellite that has to go X kph to get there means several times the extra pounds of fuel in a bigger rocket. It's the reason the New Horizons probe is so tiny and thus of limited capability; to get there quickly enough to do useful science within the career-spans of the scientists who designed it, they had to put the smallest probe on the biggest rocket they could find, and that's still with grav-assist.
A Christian told me: if you were saved you cant lose your salvation. you're sealed with the Holy Ghost
I replied: Can I refuse? Because I find the entire concept of vicarious blood sacrifice atonement to be morally abhorrent, the concept of holding flawed creatures permanently accountable for social misbehaviors and thought crimes to be morally abhorrent, and the concept of calling something "free" when it comes with the strings of subjugation and obedience perhaps the most morally abhorrent of all... and that's without even going into the history of justifying genocide, slavery, rape, misogyny, religious intolerance, and suppression of free speech which has been attributed by your own scriptures to your deity. I want a refund. I would burn happily rather than serve the monster you profess to love.
