CO2 Rocks! Perseverance can make as much oxygen on Mars as a small tree

(CNN)Humans are one small step closer to landing on the red planet.

The Mars Oxygen In-Situ Resource Utilization Experiment -- better known as
MOXIE -- has been successfully making oxygen from Mars' carbon dioxide-
rich atmosphere in a series of tests, as part of NASA's Perseverance rover
mission, which landed on Mars in February 2021.

MOXIE was able to produce oxygen on seven experimental runs undertaken
since testing began in April 2021, in a variety of atmospheric conditions
including during the planet's day and night, and through different Martian
seasons, according to research published Wednesday in the journal Science
Advances.

(Like Earth, Mars has distinct seasons, but they last longer than seasons
here on Earth since Mars takes longer to orbit the Sun, according to
NASA.)

In each run, MOXIE reached its target of producing six grams of oxygen per
hour -- about the rate of a modest tree on Earth.

"This is the first demonstration of actually using resources on the
surface of another planetary body, and transforming them chemically into
something that would be useful for a human mission," said MOXIE deputy
principal investigator Jeffrey Hoffman, a retired astronaut and professor
at Massachusetts Institute of Technology's department of aeronautics and
astronautics in a news release.

"It's historic in that sense."

MOXIE is small -- about the size of a toaster -- to allow it to fit aboard
the Perseverance rover. It is built to run for short periods, starting up
and shutting down with each run, to align with the rover's exploration
schedule and other mission responsibilities.

A scaled up MOXIE would include larger units that could run continuously
and potentially be sent to Mars ahead of a human mission to produce oxygen
at the rate of several hundred trees. This would allow the generation --
and storage -- of enough oxygen to both sustain humans once they arrive
and fuel a rocket for returning astronauts back to Earth.

MOXIE's steady output since arriving on Mars is a promising first step
toward that goal, the researchers said, although more fine-tuning is
necessary to make sure it can run at dawn and dusk -- times when the
planet's temperature is changing substantially, said Michael Hecht,
principal investigator of the MOXIE mission at MIT's Haystack Observatory.

How MOXIE works
The thin Martian atmosphere is 96% carbon dioxide, which isn't much help
to oxygen-breathing humans.

It is also far more variable than the Earth's atmosphere. "The density of
the air can vary by a factor of two through the year, and the temperature
can vary by 100 degrees," Hoffman said. "One objective is to show we can
run (MOXIE) in all seasons."

MOXIE works by dividing up carbon dioxide molecules, which are comprised
of one carbon atom and two oxygen atoms -- hence its chemical formula CO2.
It separates out the oxygen molecules and emits carbon monoxide as a waste
product.

Engineers are still testing MOXIE. They plan to push its capacity and
increase its production, with a focus on the Martian spring months when
researchers said atmospheric density and carbon dioxide levels are
particularly high.

"The next run coming up will be during the highest density of the year,
and we just want to make as much oxygen as we can," Hecht said. "We'll set
everything as high as we dare, and let it run as long as we can."

MOXIE also appears to be hardy. It has operated successfully despite
having to repeatedly turn itself on and off for the test runs -- a thermal
stress that can degrade the system over time. This would suggest that a
full-scale system, designed to run continuously, could do so for thousands
of hours, the news release from MIT said.

"To support a human mission to Mars, we have to bring a lot of stuff from
Earth, like computers, spacesuits, and habitats," Hoffman said in the
statement. "But dumb old oxygen? If you can make it there, go for it --
you're way ahead of the game."

My first question is why NOT use ROAD TAX dollars (And/Or get those
Billionaires to donate to a fund) to build them here on planet earth to
solve the Democrats FAKE issues of GLOBAL WARMING.... If the MOXIE
Oxygen generators were run 24/7 by your solar panels, or wind power,
we'd be solving the Democrats issues of CO2. And since CO2 isn't
causing the Planet to heat it won't solve anything but it will allow us
to remain FREE (which I'm sure is why Democrats won't promote that
idea), they can build better MOXIE CO2 Converters here on Earth and
solve the fears that Democrats and the Global Warming cult has with CO2.

And then ship some to Mars to solve the Combustion Engine problem we
have on Mars that humans surly must have also cause with all those cars
on Mars. After all it has to be HUMAN CAUSED CLIMATE CHANGE ON MARS that
killed the planet doesn't it?

The result is DEMOCRATS lies about history and reality to themselves and
others means their attempts to figure-out what's wrong is an exercise in
futility, because what they think they know they really don't know, and
fixing problems without the truth... becomes a fools errand.
