It is unclear how much can be reversed from it, but even if there is only a small gain, it will be of great help to human civilization that is still in the early space age.
A certain civilization that entered the interstellar era created it, and then sown it on the chaotic planet that had just formed an atmosphere to open up colonies for its own civilization.
With the environmental modification ability of this kind of microorganism, as long as the methods and modification plans used are appropriate, creating such a closed biosphere on Mars may not be a problem.
Once this idea started, he couldn't stop it. The more Lu Zhou thought about it, the more he felt it was possible.
Coupled with the contamination of some bacteria and microorganisms, health and safety has become an issue that cannot be ignored on the lunar scientific research station. Just to transport those domestic wastes back to the earth has already occupied the capacity resources of an entire transport ship.
If his idea is true, then the microorganisms in his hands at this moment will not be as simple as a "space version of waste purifier", but a living fossil from a certain advanced civilization!
In fact, this is almost inevitable.
This solar system might really be "designed"...
However, the emergence of Dr-111 active microorganisms brought a turn for the better.
This interesting microorganism will multiply wildly in an atmospheric environment with high carbon dioxide concentrations, growing exponentially and even covering the surface of the entire planet.
If the population continues to expand, I'm afraid the Lunar Orbit Construction Committee will have to plan a special route for transporting feces and urine.
However, this population growth is not unlimited.
The reason for making such an arrangement is not entirely because people imagine that the cost of maintaining an astronaut living in space is too high, but because the actual conditions do not allow it.
After completing all these tasks, a chaotic planet covered by carbon dioxide may only need dozens of sidereal years to complete the atmospheric evolution process that originally took hundreds of millions of years to complete.
According to the needs of an adult's normal life, the domestic waste produced in a day is about 1 kilogram, of which metabolic waste accounts for more than 50%. However, there is almost no way for the lunar scientific research station to completely dispose of these metabolic wastes.
This thing is simply an excellent waste purification material!
But maybe…
Although some people have been curious about who the master is and where he collected such awesome microbial samples, but due to the lack of documentation, all this is unknown.
Eventually, over countless stellar years, it acted as both a producer and a decomposer, absorbing excess carbon dioxide and releasing oxygen, accelerating the process of atmospheric evolution, and allowing more carbon elements to be fixed into something that can be used through photosynthesis. Organic matter directly utilized by organisms enters the biosphere cycle.
It is unlikely that everything will be for the best.
While drinking coffee and looking at the data fed back from the lunar scientific research station on the screen, Lu Zhou had a true expression on his face.
In the final stage, as oxygen continues to rise, photosynthesis gradually turns into respiration, and the ketones produced begin to kill the microorganism and make it lose its ability to reproduce until it completely disappears from the entire ecosystem. disappear.
It is not realistic to directly modify the atmosphere of Mars. After all, Mars' gravity is too small and there is no protection from the magnetic field. Even if an atmosphere similar to the Earth is created, it will probably be lost in the end.
Not a short period of time has passed since the establishment of the lunar scientific research station. The population living on the moon has almost doubled every year, and now has grown to more than fifty people.
In an aerobic environment, while decomposing metabolites through respiration, it will also accumulate a ketone substance. In fact, although this ketone substance is harmless to other organisms, it is harmful to itself. Harmful.
"Could this thing be some kind of artificially created atmosphere-modifying substance?"
Not only that, this creature has extraordinary tolerance to low gravity environments, and even under direct irradiation from cosmic rays, it can maintain the stability of its overall traits by decomposing and engulfing its own cancer cells.
Although the taste of direct consumption may not be ideal, this special amino acid molecular chain can be digested by most organisms, which means it can directly enter the ecosystem cycle.
After all, there are too few planets in this universe with atmospheric environments suitable for carbon-based organisms to survive, and oxidation reactions are how most organisms obtain energy.
After all, the nature of civilization is to transform nature.
Prolonged exposure to aerobic conditions causes the entire microbiome to multiply slowly and eventually self-destruct.
In addition, Lu Zhou also thought of Mars, which was so close at hand.
Only beasts would choose to obey.
But on the contrary, if it is in a high nitrogen, carbon dioxide concentration, and light environment, this microorganism will explode with amazing reproductive and feeding abilities.
But if a relatively closed large-scale biosphere is established in a limited area, the feasibility is still quite high.
What is worthy of study is not only the microorganism itself, but also the biomodification technology and genetic modification technology it may contain.
Even if the lunar planting unit can consume part of the feces and urine and allow organic matter to re-enter the cycle, the efficiency of this cycle is not very high.
While it engulfs and decomposes metabolites, it generates oxygen through photosynthesis-like processes and fixes solar energy in a special amino acid molecular chain.
After reading the experimental report from beginning to end, the expression on Lu Zhou's face became increasingly satisfied. Then at this moment, a flash of inspiration suddenly flashed in his mind - or an idea.
"I didn't expect to find such an incredible thing..."
Thinking of this, Lu Zhou somehow suddenly remembered what the observer said to him, and a thought that made him think deeply arose in his heart.
Shocked by his own thoughts, Lu Zhou's pupils gradually became filled with excitement.
Under natural evolution conditions, it may take hundreds of millions of years to turn a chaotic planet filled with carbon dioxide and nitrogen into a relatively habitable world with flourishing species.
It is simply useless to use it on the earth. Space stations and space colonies are where it really should go.
Just like the sanitation problems faced by many megacities, although the population size of the lunar scientific research station is far from reaching the level of a city, because there is no ecosystem to naturally degrade, the difficulty of solving sanitation problems is increasing. Population growth is amplified exponentially.
If a civilization develops to the level of an interstellar civilization and can expand its territory to an area within hundreds of light-years through faster-than-light means, it is not impossible to master planetary transformation technology.
No one knows where it came from. It was as if the project suddenly appeared in the database and was suddenly assigned personnel to study it one day.
As he suspected, this Dr-111 microorganism was not that simple.
Beginning this year, the Lunar Orbit Construction Committee announced that it will limit the increase in the number of permanent residents on the lunar surface in the short term, and requires management agencies to maximize the lunar surface as much as possible while maintaining the current scientific research plan and lunar resource development plan. The number of permanent personnel at the scientific research station is controlled to less than 60 people.
