Mars has right ingredients for present-day microbial life beneath its surface, study finds

New research suggests that rocks in the Martian crust could produce the same kind of chemical energy that supports microbial life deep beneath Earth's surface.

I am sure that transpermia (exchange of life/microorganisms via dust meteors) has occurred between Earth and Mars and therefore Mars certainly has life somewhere on it or in it.

I cannot even stop mold regrowing in my toilets, in spite of my best efforts. Life is tough.

Drip, drip, drip—don’t spook the herd!

Nonsense. Without a study having material from Mars, this is pure speculation. Microbes, bacteria, fungi, algae, etc, need preexisting life to grow on. These clowns know better, or do they? No.

Love your comment!
But the Moon is the place we need to be, not Mars.

[dfwgator]

Still ain’t the kind of place to raise your kids.

[downtownconservative]

Maybe they’d get in less trouble...

**New research suggests**

Well they need to better. Mercury had a radio broadcast years ago, and they were saying that Mars has some space traveling terrorists living there.

So too do the Democrats in Congress.

How much money and time will be required to do an ‘environmental impact study’ to ship all of earth’s wares to stimulate Mars life?

[kaehurowing]

It’s cold as hell.

The way our world is going I’ll gop on board a spaceship and enjoy my end of life on a debate planet. Far better than what we have going on here.

[TermLimits4All]

Ooh wait does Mars have gun control legislation? That would be a no for me if they did.

Without delving into the veracity of some random internet publication, I think the words “study finds” are pretty meaningless. Study means looking at data but data rarely shows anything completely. All it does is indicate greater or lesser probabilities. A study finds wearing masks stops covid transmission, another study finds that masks have no effect on covid transmission. Both cannot be true at the same time, yet they are.

Problem is it has no atmosphere. How are they going to get around that?

[gundog]

It has an atmosphere. That’s why our helicopter can fly. It’s mostly carbon dioxide. Pretty sure Earth had a lot more carbon dioxide before green plants.

It’s a very thin atmosphere, but sufficient for flight.

"Microbes, bacteria, fungi, algae, etc, need preexisting life to grow on.

Most do, some don't:

"Lithotrophs: Inorganic compounds are the main source of energy for lithotrophs.
These bacteria get their nutrients (inorganic compounds) from the minerals in rocks.
Bacteria are formed of carbon, oxygen, nitrogen, hydrogen and phosphorus.
They also consist of traces of other elements.
So they need to obtain these nutrients from the environment for survival.
Lithotrophs get most of these nutrients from rocks."

And there's this:

"Oct 20, 2006 · by Chad Boutin. Oct. 20, 2006 3:35 p.m.
A Princeton-led research group has discovered an isolated community of bacteria nearly two miles underground that derives all of its energy from the decay of radioactive rocks rather than from sunlight.
According to members of the team, the finding suggests life might exist in similarly extreme conditions even on other worlds."

Of course, none of this proves life does exist on Mars, only suggests that it might have, might still.

Mars does have an atmosphere that is one percent as dense as Earth's. As you go further down into any planet the atmospheric pressure increases just as it does when you go from a mountain down to sea level on Earth. I have no idea what that maximum atmospheric density could be but you can say with certainty that it would be denser than the open air.

Also, when one moves to deeper regions, the upper layers exert pressure and thus permit the existence of liquid water in principle. For instance, Mars does not currently have any longstanding bodies of water on its surface, but it is known to have subsurface lakes at the poles.

I myself would be surprised if there is no bacterial type life inside the surface of Mars. I wouldn't be surprised if there is a genetic relationship either.
