You can't just seed a hostile environment and hope for a miracle. A few isolated patches might manage to survive a single 'season', but, the odds of long term survivor prosperity are grim.
And what would it metabolize? The oxygen has to come from somewhere, there aren't very many chemicals with oxygen on Mercury, the oxygen got blasted away when the sun formed. Even if it could find a material that it knew how to metabolize, what then? How would the metabolized oxygen turn back into a raw material without a cycle to replenish it? Forget oxygen, where would the nitrogen come from? All earth life has nitrogen in it, even the extremophiles. How do you grow and reproduce without the atoms you require? Mars is easy, there is nitrogen in the soil. Mercury has none of that.anaerobic hydrogen-oxidizing bacteria
Very very wrong. Anaerobic means it does not require free oxygen. All earth life requires oxygen, it's one of the atoms that make up our DNA. Same as nitrogen. How can a create a creature made of nitrogen and oxygen atoms reproduce in an environment with only traces of one stored in rocks and none of the other?Anaerobic bacteria don't require oxygen.
How? There are no extremophiles that do this. It doesn't even make any sense from a chemistry standpoint. Mercury's atmosphere is made of atomic hydrogen, not molecular hydrogen. Life metabolizes by breaking chemical bonds which releases energy into the life-form, which then gets used for something else. The hydrogen in the atmosphere of Mercury has literally zero chemical energy in it.They can obtain all their energy from the hydrogen in Mercury's atmosphere.
Read the actual wiki you posted. It stated very clearly that the hydrogen in the atmosphere came from the sun. That's atomic hydrogen, it even specifies that it's atomic later in the article. We know what kind of atoms come off of the sun, they are not molecules.Molecular[/PLAIN] [Broken] Hydrogen on Mercury
Have a look at the list on the right-hand side of the page.
"Mercury's exospheric hydrogen and helium are believed to come from the Solar wind, while the oxygen is likely to be of crustal origin."
