Default Cassini Demise is Dumb !

Why not just let it orbit and be available
for future scientists, historians, public, etc.

All that crap about contamination and pollution
is just so much BS !

What does available mean when the system is out of fuel?

If it truly is out of fuel, it's going down anyway.
So it's a bit self-gratifying for NASA to tell us that they are doing this
noble deed of plunging it into the planet deliberately to save the moons
from contamination.
.....But I guess they have to rationalize those billions of dollars every
year, somehow.....especially after sending up a filthy satellite to begin
with.

I think it ran out of energy? So cannot do anything and if it orbits, it has our human dna on it. it may grow by itself?

Even if out of fuel, it still could have been made to orbit
indefinitely, until some future technology
was available to deal with it.

NO. In a multy-body system,orbits are unstable.
So even if you leave it alone, it will still hit something,
probably a moon, polluting it with live spores from earth.

*** That's why NASA hires experienced Space Engineers and not Spaced
Out and opinionated know-it-alls like you.
Just as with the Jupiter probe of about a decade ago, which took
valuable data when it plunged into the planet until it succumbed to the
progressively increasing pressures of the interior, the Cassini entry point
can be carefully selected for reasons only NASA has an explanation
for. However, I must admonish them for not clearing this with you and
your apparently vast reservoirs of planetary experience, knowledge and
familiarity with the Space Time Continuum.
Just because you watch a 5 hour propaganda clip of 9/11 does not make
you an expert on anything.

Multi body systems are only unstable if the multi interactions are
significant. Otherwise things go on indefinitely ( eg - Earth, Moon,
Saturn, Saturn moons ). Cassini could have been put in a very stable
orbit at an appropriate distance from Saturn, and then studied at a
much later date.

No, not necessarily. Why ?

Contamination is ( of course ) total BS.

....But I guess they have to rationalize those billions of dollars every

Well the money could have been spent on something more appropriate,
like totaly UN necessary wars in the middle east, or a ridiculous
border wall.

Any way you look at it, Cassini is an incredible feat of science and
engineering !

Ya right.
NASA has reasons for everything they sell you.
I keep telling you that.
They have to justify the billions of dollars they take from the taxpayers
every year.

Next you will be telling us that G.W. knew that 9/11 was about to happen,
and just allowed it so that they would know where the security holes were
that might allow terrorists to fly planes into buldings.
And then they used that knowledge to make sure it doesn't happen in the
future.
IT WAS RESEARCH.

That I am not stupid enough to swallow the fake news they pawn off to you
with no problem, satisfies me to no end.
