Now we know there is water on Mars.

You know, I thought they already knew (or at least suspected) this? I seem to remember some MRO pictures showing these streaks from years ago, but searching for them on the internet now seems to be futile given the waves of articles on the announcement...

I wonder when we will get on with the terraforming!

Yeah, I heard from a scientist dude in the know just earlier this morning. Iced water was confirmed a good while ago on the poles of Mars, and water leaks have been suspected to exist on Mars since at least 2010.
The important thing is that scientist can pinpoint when and where water's going to appear on Mars, which means they can send a rover and confirm if there's microscopic life on Mars. Exciting stuff!

I'm sorry, I'm lying to you. Scientists didn't found actual running water, but from what I understand, the black streaks that were previously suspected to be wet martian soil (those pics you found) were confirmed to actually be wet martian soil.
Everything else stands, scientists can sond a rover to said wet soil since it's currently the best shot at actually finding life on Mars.

Ah, that clears it up. I must have seen the "suspected" ones. I knew about the frozen deposits, but yeah, liquid water certainly opens up more possibilities for life!

Good point about sending a rover, I hadn't actually thought about that, but I suppose now we have a new phenomena to explore that'll be the location of the next mission.

A lot of news sites say "running water" or "flowing water", but it's really water that is percolating through the soil over a long period of time.

Still, there is a possibility of microscopic life. I'm not sure if microscopic life is sustainable with the level of radiation on the surface of mars, though.
Does anyone know anything about how likely it is that microscopic life can exist under those conditions?

Life exists on Earth that can survive easily under those conditions (e.g. https://en.wikipedia.org/wiki/Deinococcus_radiodurans or https://en.wikipedia.org/wiki/Tardigrade ) but of course these are fairly evolved creatures, so I don't know how far they speculate life could have gotten under those levels of radiation.
