There’s life on polar ice sheets, in scalding hot springs, and kilometers underground. But in hot briny lakes in Africa’s Rift Valley and the cold, dry soil of Antarctica’s Shackleton Glacier Valley, life reaches its limits. In both places, teams of researchers have pinpointed conditions too hostile for even the toughest microbes.
In the Rift Valley lakes, in Ethiopia, volcanic gases venting from below acidify the water, which is also rich in salts from brines created by the evaporation of ancient and modern bodies of water. Add the heating effect of the volcanic activity, and the lakes represent an environment more extreme than any found in Yellowstone National Park or even in the Atacama Desert.
This is the chemical beginning of which life sprang from. with the help of Volcanoes to shape climate
]]>And of course I think a quick answer about life being present. It seems to me it is rather unlikely that Methane would build up without brine being present. So, I am thinking ~Equator.
Rather hope SpaceX is flexible in their thinking. Never was in love with the Shackleton near death march at high latitudes for water ice. Rather have palm trees Well maybe in caves in sandstone.
Done.

so theses bacterial capture of brine can be combined with processes in construction industry. Ethylene is generated by fixing carbon dioxide with hydrogen. Bacterial capture of calcium chloride, ethylene and water or an oxygen carrying chemical agent are converted to calcium oxide and vinyl chloride with some hydrogen chloride. Vinyl chloride is polymerized to PVC which is used for pipes. The calcium oxide and the silicate minerals on Mars generate the cement. With other minerals and the steel produced on Mars, reinforced concrete and PVC pipes are then available for building.
All technologies mentioned are readily available except the part that converted calcium chloride or perchlorate to oxide and chlorine chemical species. Thanks to terraformer, that part is also known to be available. So if calcium are found in bulk on Mars in chemical compounds such as the perchlorate, the bacterial capture of brine can be a contributor to a human settlement, on paper....

]]>Bacteria may travel thousands of miles through the air globally
So, if true I would speculate on two possibilities of how (There could be others).
1) Birds somehow spread the bacteria so that they can interact globally. Perhaps involving their digestive tracts and feeding and drinking behaviors.
2) Some bacteria can levitate into the atmosphere themselves, or their spores? I am thinking of electrical levitation. Sometimes spiders do it, and they are much larger than bacteria, microbes, or spores. If this were possible then it could explain how swarms of bacterial sized particles can hang out in the clouds of Venus. Presuming that they are alive microbes, and can levitate, and also tolerate/prosper in all the other conditions they would be subjected to. Acid for one. U.V. for another. Nutrients???
Done.
]]>I am looking at Venus, but of course, it is possible that there were at least 3 habitable worlds in the early solar, system, Mars and Venus included. So, yeah, maybe panspermia.
So, perhaps to drive any panspermia in those early days, this matters:

It is known that gas giants around other stars are often located very near their sun. According to accepted theory, these gas planets were formed far away and subsequently migrated to an orbit closer to the star. Now, researchers from Lund University and other institutions have used advanced computer simulations to learn more about Jupiter's journey through our own solar system approximately 4.5 billion years ago. At that time, Jupiter was quite recently formed, as were the other planets in the solar system. The planets were gradually built up by cosmic dust, which circled around our young sun in a disk of gas and particles. Jupiter was no larger than our own planet.
The results show that Jupiter was formed four times further from the sun than its current position would indicate. "This is the first time we have proof that Jupiter was formed a long way from the sun and then migrated to its current orbit. We found evidence of the migration in the Trojan asteroids orbiting close to Jupiter," explains Simona Pirani, doctoral student in astronomy at Lund University, and the lead author of the study.
These Trojan asteroids consist of two groups of thousands of asteroids that reside at the same distance from the Sun as Jupiter, but orbiting in front of and behind Jupiter, respectively. There are approximately 50 per cent more Trojans in front of Jupiter than behind it. It is this asymmetry that became the key to the researchers' understanding of Jupiter's migration.
"The asymmetry has always been a mystery in the solar system," says Anders Johansen, professor of astronomy at Lund University. Indeed, the research community had previously been unable to explain why the two asteroid groups do not contain the same number of asteroids. However, Simona Pirani and Anders Johansen, together with other colleagues, have now identified the reason by recreating the course of events of Jupiter's formation and how the planet gradually drew in its Trojan asteroids.
Thanks to extensive computer simulations, the researchers have calculated that the current asymmetry could only have occurred if Jupiter was formed four times further out in the solar system and subsequently migrated to its current position. During its journey toward the sun, Jupiter's own gravity then drew in more Trojans in front of it than behind it.
According to the calculations, Jupiter's migration went on for around 700,000 years, in a period approximately 2 to 3 million years after the celestial body started its life as an ice asteroid far from the sun. The journey inward in the solar system followed a spiraling course in which Jupiter continued to circle around the sun, albeit in an increasingly tight path. The reason behind the actual migration relates to gravitational forces from the surrounding gases in the solar system.
This is rather early in the solar systems life, but the aftermath of the scattering of objects could have lived on for some time afterwards where scattered bodies may have still been trying to acquire a new harmony, and failing to the point of collisions deeper into time. And of course I have a suspicion that interstellar panspermia is quite possibly possible. In that case, all you need is a wet body and some chemicals to make a place for critters to live.

Then I found reference to this critter:
https://en.wikipedia.org/wiki/Ferroplasma_acidiphilum
Quote:
Ferroplasma acidiphilum is an acidophilic, autotrophic, ferrous iron-oxidizing,[1] cell wall-lacking, mesophilic member of the Ferroplasmaceae.[2] F. acidophilum is a mesophile with a temperature optimum of approximately 35 °C, growing optimally at a pH of 1.7. F. acidophilum is generally found in acidic mine tailings, primarily those containing pyrite (FeS2). It is especially abundant in cases of severe acid mine drainage, where other organisms such as Acidithiobacillus and Leptospirillum lower the pH of the environment to the extent that F. acidophilum is allowed to flourish.
F. acidophilum obtains energy by oxidation of the ferrous iron in pyrite using oxygen as a terminal electron acceptor. This process produces sulfuric acid as a by-product, leading to further acidification of its environment. Its type strain is YT.
Not quite what I want, but interesting, Venus now has an acid environment, and Mars apparently had a wet acid environment towards the end of it's presumed habitable era. So, useful.
……
And a general background of extreme organisms:

I Won't clutter things with these quotes.
One thing I did discover about some of the acid lovers is that they would like to eat metals such as iron, in some variations.
So, then I wondered about dust in the Venus atmosphere. I am not aware of good information on that subject. I do know that about ~1/2 of the Venus surface is involved with supercritical CO2, and that the winds even if slow, will be like ocean currents due to the density of the atmosphere. So, I speculate without proof at this time that the surface and/or volcano's can generate dust with metals which could get involved in the cloud deck.

A dust ring for Venus, speculation predicts some asteroids associated with Venus as the source:

Again, read for yourself, I will spare the quotes.

Again sparing quotes:

Somewhat old, suggesting that life even now if it existed on Venus could be blown to Earth under certain situations.
Probably disputed, I would presume.
……
Anyway Aluminum 26 in our small accreted objects are presumed to have made them into mud balls for millions of years in the early formation of the solar system. The asteroids would then either become something on the order of dwarf planets, or maybe even comets later.
So, trying to condense my post, I speculate that when the gas giants may have migrated, they would have bombarded quite a few planets by perturbing the orbits of such dwarf planets and lesser objects, and the result could have been Hot springs, even acid hot springs on Mars for some time, and also eventually acid clouds on Venus. If we believe that the Moon formed by an impact of a Mars sized object to Earth, then I presume that a possibility could exist that Mars and Venus were alive, and Earth was scorched. But later when Venus and Mars, were deteriorating, perhaps life came to Earth from one or both of them. And it is in my mind possible that it's origins could be interstellar.
I'm done.
