Want to Breathe on Mars? A Sea-Dwelling Bacteria Could Make That Possible.
  NASA/Matthewjparker/Victor Tangermann
by Kristin Houser	June 17, 2018 Off World
Forget constructing cool Martian habitats, growing food, or digging 
tunnels. If we can’t figure out a way to breathe on Mars, what’s the 
point of all of our colonization plans?

Now, we may have a new hope in the hunt for a steady supply of oxygen on 
the Red Planet: cyanobacteria. This family of bacteria sucks up carbon 
dioxide and discharges oxygen in some of Earth’s most inhospitable 
environments. On Friday, a team of researchers published a new study in 
the journal Science linking the tiny organisms to the possibility of 
human life on Mars.

Remember photosynthesis? It’s how plants and other organisms convert 
sunlight into energy. Cyanobacteria also use photosynthesis to produce 
energy, but they’re able to do so in conditions with far less sunlight 
than what you need to grow your tomato plants. In fact, scientists have 
found cyanobacteria thriving in the deepest trenches in the ocean.

A key part of the photosynthesis process is the chemical chlorophyll. 
Most plants and organisms convert visible light into energy using 
chlorophyll-a. The researchers figured out that cyanobacteria use a 
special kind of chlorophyll, chlorophyll-f, to convert far-red/near 
infrared light into energy. This is how they’re able to live in such 
low-light environments.

“This work redefines the minimum energy needed in light to drive 
photosynthesis,” study co-author Jennifer Morton said in a news release. 
“This type of photosynthesis may well be happening in your garden, under 
a rock.”

The upshot: we can send cyanobacteria to Mars to produce oxygen for 
colonists in the future, the researchers note. We’ve already found the 
organisms living in the Mojave Desert, Antarctica, and even on the 
exterior of the International Space Station (ISS), so they seem 
well-equipped to survive the harsh conditions of our planetary neighbor.

“This might sound like science fiction, but space agencies and private 
companies around the world are actively trying to turn this aspiration 
into reality in the not-too-distant future,” said study co-author Elmars 
Krausz in the press release. “Photosynthesis could theoretically be 
harnessed with these types of organisms to create air for humans to 
breathe on Mars.”

Now that we have a solid lead on a source of extraterrestrial oxygen, go 
ahead and start mentally constructing that Martian habitat of your 
dreams. You might not be able to actually live in it for another couple 
of decades, but at least you’ll likely be able to breathe once you move in.

Weird Low-Light Bacteria Could Potentially Thrive on Mars
The photosynthetic organisms subsist on redder, lower-energy light than 
other species, and could be a new source of fuel and air for 
interplanetary outposts

An international team of scientists has found that a strange type of 
bacteria can turn light into fuel in incredibly dim environments.

Similar bacteria could someday help humans colonize Mars and expand our 
search for life on other planets, researchers said in a statement 
released with the new work.

Organisms called cyanobacteria absorb sunlight to create energy, 
releasing oxygen in the process. But until now, researchers thought 
these bacteria could absorb only specific, higher-energy wavelengths of 
light. The new work reveals that at least one species of cyanobacteria, 
called Chroococcidiopsis thermalis—which lives in some of the world's 
most extreme environments—can absorb redder (less energetic) wavelengths 
of light, thus allowing it to thrive in dark conditions, such as deep 
underwater in hot springs. [Extreme Life on Earth: 8 Bizarre Creatures]

"This work redefines the minimum energy needed in light to drive 
photosynthesis," Jennifer Morton, a researcher at Australian National 
University (ANU) and a co-author of the new work, said in the statement. 
"This type of photosynthesis may well be happening in your garden, under 
a rock." (In fact, a related species has even been found living inside 
rocks in the desert.)

By studying the physical mechanism behind these organisms' absorption 
abilities, researchers are learning more about how photosynthesis 
works—and raising the possibility of using similar low-light organisms 
to generate oxygen in places like Mars.

"This might sound like science fiction, but space agencies and private 
companies around the world are actively trying to turn this aspiration 
into reality in the not-too-distant future," Elmars Krausz, study 
co-author and a professor emeritus at ANU, said in the statement. 
"Photosynthesis could theoretically be harnessed with these types of 
organisms to create air for humans to breathe on Mars.

"Low-light-adapted organisms, such as the cyanobacteria we've been 
studying, can grow under rocks and potentially survive the harsh 
conditions on the Red Planet," Krausz added.

Researchers originally thought that a particular chlorophyll pigment, 
called chlorophyll f, helped capture light but couldn't directly 
participate in converting it into energy, according to the new work, 
which was released yesterday (June 14) in the journal Science. But this 
research shows that, in fact, the pigment does participate in energy 
conversion, and lets the organism pull energy from longer wavelengths 
than ever observed.

"Chlorophyll adapted to absorb visible light is very important in 
photosynthesis for most plants, but our research identifies the 
so-called 'red' chlorophylls as critical components in photosynthesis in 
low-light conditions," Morton said.

Not to mention, it could play a key role in the search for life beyond 
Earth: "Searching for the signature fluorescence from these pigments 
could help identify extra-terrestrial life," she said. Knowing such 
organisms exist on Earth not only broadens where we look for alien 
organisms but also suggests what to search for when we look.

The trouble with this notion is that there isn't much CO2 on Mars
either.  So the cyanobacteria could separate _all_ of it and there
still wouldn't be a breathable atmosphere.

I think the idea is just to produce enough oxygen 
from CO2 for your personal consumption, while you are 
a near-inexhaustible source of CO2, at a limited rate.

Yup, Kim Stanley Robinson wants to crash a comet into Mars.  Then build 
many nuclear reactors to melt the water.

An asteroid crashing into Mars is credited (?) with turning the
planet's magnetic field off in the first place.  Whether doing it
again would reboot the field is something I don't know.

That is very tough to simulate.  Therefore, try it.  What could go wrong ?

Uh, we are talking about Mars.  Not Earth.  Please not Earth.

In my most recent Stellaris run I found a star named Sol, and Sol III 
was a Tomb World (an irradiated post-apocalyptic world). It was 
inhabited by a pre-sapient Arthropod species called "Cockrocahces". I 
uplifted them.

I did also get an opportunity to try to terraforming a planet with a 
judiciously placed asteroid. Unfortunately the scientist in charge 
messed it up. Didn't blow up the planet, though.

I saw a headline this morning: 

"America Isn't Ready to Handle a Catastrophic Asteroid Impact, New
Report Warns"

To which my immediate response was "Really? What was your first clue?
And do you actually know the meaning of the word 'catastrophic'?" 

The article itself isn't too bad, just a dumb headline.

Are we talking about actual Mars or your personal vision?
Hmm... I got the idea Mars's core cooled down and is solid,
but it seems not.  Not all of it.

Earth has a magnetic field because of fluid moving in the 
core, I think.  Mars indeed doesn't have a magnetic field,
but I think that the core wouldn't notice an "ordinary"
sized asteroid striking the surface.  But the idea that
a shower of asteroids or one big one did it, seems to
b around.

I find myself wondering if Earth's magnetic field is the result of
tidal activity in the core--the Moon keeps things going in other
words.

What we need to do to Mars before trying to give it an atmosphere
is to restart its magnetic field.  I'm working on and off (mostly
off) on a space opera in which that was done, and Mars
subsequently terraformed, back in the mythical times Before The
Interregnum which nobody remembers much of, so that I don't have
to explain how it was done.  :)

In the Star Trek series, "Star Trek Twilight's End" by
Jerry Oltion, they plan to start a planet spinning.
Which, would probably be one way.

from
https://www.amazon.com/Twilights-End-Star-Trek-Original-ebook/dp/B000FC0VY8

"Unlike most planets, Rimillia does not spin upon its axis so its day 
and night sides are subject to perpetual extremes of hot and cold. 
Habitation has only been possible on a thin band of the planet's 
surface...until now.
Using gigantic impulse engines of unimaginable power, the alien Dumada 
intend to start Rimillia rotating, rendering the entire world fit for 
colonization. Yet some fear the enormous stresses involved may tear the 
planet apart.
Assigned to assist the Dumada, Captain Kirk must rescue a kidnapped 
scientist vital to the rotation project. But, once the giant engines are 
activated, can even Scotty save Rimillia -- and the U.S.S. Enterprise™ 
-- from total destruction."

*spoiler space*


A malfunction catapults the ship /Hogan's Goat/ several billion years
into the future in "One Face" (Niven). The premise is that you can
think your way through any problem. 
    The /Goat's/ crew and passengers finds themselves in an aged Solar 
system where only one side of a now spinless Earth faces a shrunken Sun.
For lack of any alternative, the /Goat/ lands near the Earth's equator.
Then the ship's unobtainium is used to kickstart the Earth's spin.

Thank you,
