Default Phoenix and the Intraterrestrials

Interestingly enough, the NYT features a fascinating article today, about biological activity behind some geological processes here on Earth. It drew my attention as Phoenix carries out its mission on Mars. Take this quote from Phoenix Pincipal investigator Peter Smith: "There's something very unusual about this soil, from a place on Mars we've never been before. We're interested in learning what sort of chemical and mineral activity has caused the particles to clump and stick together." And take this quote from the NYT article: "Until recently, it was assumed that the chemical alteration and decomposition of rocks in the ocean crust was due purely to elemental forces — the circulation of seawater, the grinding of rocks against one another. But increasingly, intraterrestrial bacteria are suspected of making a contribution, too. Shards of volcanic glass from basaltic rocks hundreds of meters beneath the seabed show grooves and etchings that appear to have been made by bacteria."

I see a striking relationship between the research described in the article and current developments on Mars. Read the article, and maybe youŽll start to follow the Phoenix saga with an extra bit of amazement.

Meet the Intraterrestrials

There might be a deep hot biosphere on Mars, but it would take more than Phoenix to detect it. We'd need to send some serious drilling equipment.

There may even be a fossil deep hot biosphere, which has died out because of cooling in Mars' crust. What kind of temperature gradient would we expect to find with depth in the rocks of that world?

Sure. The fact that you can find biologic activity so deep underground on Earth is a function of the sheer 'biologic density' of the Earth. But what IŽm hinting at in this case is that 'expect the unexpected' has never sounded so real. If micro-organisms can play such a role in these extreme environments, the possibility of analog activity [closer to the surface] on Mars looks touchable [or maybe I have fallen in love with this idea].

It would certainly be cool. I wonder if Phoenix actually has the equipment to detect that, though.

Hmmm...if you could sell Pet Rocks and Sea Monkeys, would there be a market for Martian Extemiphilic Bacteria?
