You're the one who used the word "thrive". These are*not* examples o bacteria thriving under something close to Mars conditions. These are
examples of them surviving exposure to vacuum, but they weren't growing,
weren't reproducing, and etc. They were essentially dormant.

Yes. I was answering to you saying:

Not near vacuum. Try again.

OK, now that THAT objection is cleared you change the subject and admit
that bacteria can survive total vacuum.

They can also survive an hypervelocity impact, so even if the spacecraft
crashes and all humans are dead, their bacteria could survive.

But I see that with scientific arguments (published papers, etc) you get
nowhere in a newsgroup where anybody can say anything and when proved
wrong they just change the subject...

Plants have been grown using simulated marsian soil, not under vacuum
conditions but that proves that nutrients are present... Bacteria are
far more resistant than plants, and could develop after a probably long
adaptation period.
