Life in a hostile environment deadly to anything else? I'd say every fan of space exploration should have a look at it. Sooner or later we'll find something like those brine pools and their weird ecosystem beyond the Earth. At least we'll know what are we looking at.

I was thinking mars.

Maybe, but I'd be interested to see how they'd keep their water liquid in the near vacuum. I think life is most likely in the mantles of the ice moons. Unfortunately it's really hard to get down there, so it'll be a few decades before we get to it.

Because atmospheric pressure increases with depth and vapor pressure decreases with salinity.

So they'd be deeper underground.

I would think so, satisfying the energy requirement, heat requirement, water requirement, given the martian core has solidified, it could be 10s of kilometers underground.

At least if I was NASA a place were you could test a vent or something to see if life forms were aerosols are being produced.

Again the expectation is not profound, because there is an oxygen dependency for complexity of organic life, without this life can only exist to its simplest forms with a dependency on oxidized sulfur and nitrogen, and diffusion limited.

Mitochondria free eucaryotes.

I can't believe the forum trolls on Science.  Then again, that publication will draw the denialists and cranks like no other.
