Oxygen Extracted from Martian Atmosphere - a first

In summary: We’re talking about a hundred thousand, hundreds of thousands of barrels of industrial waste, much of it toxic, that we just dumped there because it was easy," said Jeff Selbin, a marine biologist and executive director of the non-profit group Heal the Bay.The dumping happened between the Long Beach and Catalina Islands in the middle of the ocean."It’s one of these things where we all know it happened, but we don’t know exactly what happened," Selbin said.Heal the Bay is calling on the state and federal governments to come clean about what happened and to take action to prevent it from happening again.“We need to find

On April 20, 2021, an experiment on the NASA Perseverance Mars Rover broke down the CO2 Mars atmosphere to 2CO + O2. That makes it the first instrument to produce Oxygen on another world.

Still a ways to go, design maximum is 10 grams per hour, people need around 60 grams per hour.

Exciting!

Not keen on the 2CO for every O2 through

Yeah, definitely not a long-term solution!
Sorta like what we're doing here on Earth with generating CO2

Why not? Combine it with O2 production from water and you have synthesis gas. That means it is not just the first O2 extraction but also the first step to the production of propellants or even plastics on mars.

Since this is on Mars, first you have to find the water. 😁

You are not up to date. The water already has been found, e.g. by the Phoenix lander:

There is water ice sequestered in the rocks under the surface. The planet bis long dead

Ice water is ok for this?

In principle yes, but it will be a technical challenge to mine it on Mars. Maybe it is possible to drill a hole and to melt or sublimate it underground.

so throw it away!

Yes, what could possibly go wrong?

1. How was oxygen extracted from the Martian atmosphere?

The oxygen was extracted using a process called electrolysis, which involves passing an electric current through a mixture of water and carbon dioxide found in the Martian atmosphere.

2. Why is extracting oxygen from the Martian atmosphere significant?

Extracting oxygen from the Martian atmosphere is significant because it could potentially provide a sustainable source of oxygen for future human missions to Mars, reducing the need for costly and risky resupply missions.

3. What are the potential applications of the extracted oxygen?

The extracted oxygen could be used for breathing by astronauts, as well as for producing rocket fuel for return trips to Earth. It could also be used for creating habitable environments for future human settlements on Mars.

4. How much oxygen was extracted from the Martian atmosphere?

The amount of oxygen extracted from the Martian atmosphere in this first experiment was a small amount, about 10 grams. However, this proves that the process is possible and can be scaled up for larger amounts in the future.

5. What are the challenges of extracting oxygen from the Martian atmosphere?

One of the main challenges is the low atmospheric pressure on Mars, which makes it difficult to extract and store oxygen. Additionally, the equipment needed for extraction and the energy required for electrolysis must be carefully designed and optimized for the Martian environment.
