That's a really helpful review!.. Naht!
I don't like the earlier video either. It's massively dumbed down. I was taught in secondary school chemistry that you cannot refer to a substance simply as "ice" since ice is a state, not a substance. For example, the normal state of iron on earth is as a frozen solid, or ice. So it's fair to say that most nuts, bolts and nails are made of ice. (ferric ice, to be more precise)
What is the chemical composition of this "ice", and if it is essentially, predominantly H²O then "the interaction between ice and water" you are talking about is actually an "interaction between water and water", at which point you have dumbed down what you are saying to the point where you are no longer saying anything at all. We have to assume you are referring to an interaction between frozen water and liquid water.
However, we know that polar ice caps flow as though they where liquid over a much more extended period of time. If there is no influence from animals and atmospheric disturbance, there would be no way of knowing that these movements and the geological effects they produce where made by frozen water over a long period of time, rather than liquid water over a relatively short period of time.
So... are we now talking about frozen water and
more frozen water? Or possibly frozen pure water and frozen water with higher concentrations of diluted salts? At this point, I don't know. There is not empirical 2 million year + scientific earth bound study into how such interactions may occur.
When scientists start making grand claims about understanding what they see in situations like this, I tend to think you would get more reliable answers by pressing your hands together and closing your eyes. At least that guy was around to watch it happen, even if his answers tend to be a bit cryptic.
tt1:
The difference between water being frozen and water being liquid, or even gaseous is non-existent from the point of view of looking for, or looking to seed micro-organisms. Earth bound microbes can be seen to live and breed both in extreme sub-zero temperature waters and liquids way above boiling point.
The important factor is "water". This is what is also interesting about the river beds and frozen underground water of Mars. Carbon based organic life on earth requires water and carbon to exist, and light to fuel growth and multiplication.
Frozen microbes could well be in a state of hibernation, and therefore be "awakened" with a simple warming. This could tell us a lot about the decline of a previously living world and allow us to make better predictions about potential future events on our own.
Seeding micro-organisms on a completely dead world could eventually create a self-sustaining habitable world from a presently dead one. The self-propagating factors of life it's self mean that any biomass will attempt to both adapt and survive in the environment it finds it's self, and adapt that environment to one more suited to it's existence.
If you take Mars as an example, it is highly suited to plant life, but couldn't sustain organisms larger than microbes at present. If enough could be introduced and adapt to it's present condition, they would begin to consume the carbon-monoxide atmosphere and excrete carbon-dioxide, and possibly repair the missing radiation shielding layer from the Martian atmosphere, allowing temperatures to become more temperate and providing possibilities for animal life.
However, that process would also take millions of years, and is not likely to be of any benefit to us. I believe, Sheen, that you are correct in thinking that we, this civilisation, will not live to see any such thing come to pass.
What would be more interesting to this culture is iron deposits, and the possibility of collapsed biomass on now dead worlds.
Former oceans filled with even microbial life forms will probably now have decomposed into oils and gasses. If they can be harvested and returned to us profitably, they would provide a much needed transfusion for our presently failing industrial culture.
In that scenario, the hostile living conditions off-world will be populated by a distinctly "blue collar" population in order the fuel the comfortable existence of the elites back on our home-world. ^_^
In fact, a significant find may even give
me more hope for the potential sustainability of this way of life. Because if we could maintain our space programs (heavily fossil fuel dependant, not only for the journey but the energy that drives the machinery which constructs these vessels) then there may be a slight hope that we could perfect alternate, and quite possibly space bound energy harvesting technologies.
Nuclear, and solar energy abound outside our safe atmospheric confines... but harnessing and transporting those energies to a place and form we can utilise them is still quite beyond us.
I am now convinced it will still be beyond us when our fossil fuel resources are completely depleted, and no amount of renwable or even nuclear energy will allow us to continue forging metals, replace oil based plastics, paints and polymers or even fuel recycling projects for any practical period of time. :*:
A successful off-world fossil fuel mining expedition is one of the few things which might give me hope for a way out of the dead end we are heading towards. But we'd have to recognise it for the "hail Mary" that is, and use it to get off this oil crack addiction our culture currently has.
