Because those "mushrooms" were squashed by the wheels of Curiosity, it only took one day (a Mars day, about 24.6 hours) to grow again. Moreover, it seems that this kind of "mushroom" has grown on the top and deck of Curiosity Rover!
Well, if that's the case, isn't it the end of the history that there is no alien life in the solar system? Alien life really appeared! Why hasn't such earth-shattering news been widely publicized in the mainstream media? On closer inspection, it turned out to be just suspicion.
The source of this news is not folk rumors, but the conclusion reached by Dr. Wei Lixin, a microbiologist of China Academy of Sciences, Dr. Rudolf Schroeder and Dr. Ryan Gabriel Joseph, astrophysicists of Harvard Smithsonian, after studying the photos taken by NASA's Curiosity Rover and HiRISE orbiter.
The news comes from a pre-printed paper to be published in the journal Advances in Microbiology. Their research shows that these "mushrooms" seem to appear and disappear in a few days, weeks and months, and these fungi similar to the earth's "Mabo" "re-germinate" in the rut left by Curiosity Rover.
They claimed to have found these by analyzing more than 40 photos. In addition, they also found "dark channels" in Martian soil, which are large-scale colonies of black fungi, molds, lichens, algae, methanogens, sulfur-reducing species and so on. These fungi can grow to 980 feet in spring, the temperature can reach 42 degrees Fahrenheit during the day, and will disappear when the temperature drops to -9 degrees Fahrenheit in winter.
According to these "evidences", they think that there is life on Mars, and these "lives" are probably brought by the Earth spacecraft. Since the 1960s, human spacecraft have been searching for Mars, and these spacecraft have not been strictly disinfected before launch, so there may be many small creatures such as "fungi" on the spacecraft.
From this, they think that human beings have been sowing the seeds of life to Mars, and it is surprising that there is no life on Mars.
After they made such a firm conclusion, it seemed to subvert my cognition. Why do you say that? Because I know that NASA has been exploring Mars for decades and trying to find evidence of life. So far, there have been few breakthroughs.
The biggest discovery is that there is water on Mars. Even in ancient times, there was evidence of surface water on Mars, but only underground frozen water was found, and even surface water was not found. The National Aeronautics and Space Administration (NASA) has always been a place where scientists gather and there are many talents. NASA didn't find life on Mars, but these little-known "doctors" claimed to have found life with a few photos that others didn't study well.
In addition, I know that even fungi must survive and reproduce in an organic environment. So far, there is not enough organic matter in the soil of Mars. A few years ago, it was thought that there was no organic matter in the soil of Mars. Fungi are heterotrophic, so how can "mushrooms" grow in soil without any organic matter?
Heterotrophic substances, also known as exotrophic substances, cannot synthesize organic matter by themselves, and must rely on exogenous organic matter as food to obtain energy by decomposing and oxidizing organic matter. Fungi are heterotrophic. They don't have chloroplasts, so they can't carry out photosynthesis, that is, they can't use sunlight to make their own organic nutrients. They can only rely on extracellular enzymes secreted to decompose external organic matter to obtain nutrition.
Therefore, in order to find life on Mars, we must first find out whether there are organic substances on Mars. So is there any organic matter on Mars? It is also possible.
One is that the National Aeronautics and Space Administration (NASA) of the United States published a message in the journal Science on 20 18, claiming that organic matter was found on Mars. Also the Curiosity Rover, in a place called Gail Crater on Mars, organic matter was found in Turan samples taken from mudstone 3 billion years ago. However, it does not specify what these organic substances are and what their content is. The rover also detected methane in the atmosphere, which changes with the seasons.
Organic molecules contain carbon and hydrogen, and can also contain oxygen, nitrogen or other elements. These organic molecules are usually related to life, but they can also be produced by abiotic processes, so they are not necessarily signs of life.
Another study was conducted by a research team from Imperial College London, University of London. By studying the landform and iron-rich soil of Mars, they think that an acidic river in Dorset, southwest England, is similar to the ancient environment of Mars, where they found fatty acids, so they "applied" their research results to Mars, thinking that there may be organic matter on Mars that is full of 1.2 million Olympic swimming pools.
But after all, this is just an "application" and cannot be taken seriously. Even if Mars really has organic matter that fills 1.2 million swimming pools, it will add up to a ball with a diameter of more than 300 meters, and Mars is a big ball with a diameter of 6,779 kilometers, which is really hard to find on Mars.
Mars "mushrooms" and "lichens" have sprung up so much and so big overnight. If Mars is really so easy to grow life, then Martian organic matter is at least everywhere. How is it possible that four or five rovers and several detectors searched for more than ten years on Mars before finding any organic matter? This is too inconsistent with the sudden outbreak of life rhythm, isn't it?
So this statement has not caused much sensation in the scientific community. Although controversial, there seems to be no wave. I probably think this judgment is too rash and full of loopholes. Most scientists may think that there is no discussion value, so no one cares.
In particular, the so-called "no life is surprising" statement, even I think the words are too shallow, almost without scientific spirit.
If according to this statement, there are more people exploring the moon, there are far more detectors on the moon than Mars, and even more people have landed on Mars, then there are no towering trees growing on the moon long ago? Now, the probes launched by NASA have visited all the planets in the solar system, and the farthest ones have reached Pluto and the Kuiper Belt. Isn't that sowing the seeds of life all the way, and the solar system is full of life?
In addition, humans have plans to transform Mars. The basic content of this plan is to make greenhouse gases on Mars first, then melt groundwater, then transform the atmosphere of Mars, and then sprinkle the earth's organic matter and plant seeds on Mars. This process takes thousands or even hundreds of thousands of years.
If we follow these "mushroom life theories", won't the Mars transformation plan being discussed by NASA and scientists around the world be confusing and unnecessary? Scatter a bunch of bacteria or seeds on Mars? Why tens of thousands of years? Moreover, you only need to bring a bunch of earth creatures and sprinkle them, and you can transform any extraterrestrial planet. Why bother with such a simple matter?
Therefore, I think this life theory of Mars "mushroom" not only insults the IQ of melon people, but also insults the IQ of scientists all over the world. Speaking of which, someone has to ask, since this "mushroom" is not life, what is it?
But this magic is not man-made, but a masterpiece of nature. This magic is "water", the magic that the frozen water in the underground of Mars changes under natural temperature conditions.
The author of "Mushroom Life Wheel" said that the temperature of Mars there is 42 degrees Fahrenheit during the day, about 5 degrees Fahrenheit, and it is -9 degrees Fahrenheit in winter, about -22 degrees Fahrenheit; According to the general data, the Martian equator in summer can reach 35 degrees during the day, and the temperature difference between day and night is very large, and it drops to MINUS 70 degrees Celsius or even lower at night.
The groundwater on Mars is probably high salinity, and the freezing point of high salinity water is very low, and it usually takes MINUS 10 degrees Celsius to freeze. The special climatic conditions of Mars just provide the conditions for this underground frozen water to become "magic". In summer, when the temperature rises, groundwater gushes out from cracks. Because of the small gravity of Mars, the surface tension of water is more likely to condense into a ball by itself, just like dew on a lotus leaf.
These dewdrops are frozen, just like mushrooms. This can also explain that the "mushrooms" crushed by the rover will later develop ruts; This can also explain that patches of lichen can grow to 980 feet (298.7 meters), which are actually condensed by water gushing out of a big crack.
And those "mushrooms" growing on the top deck of Curiosity rover are probably "dew" condensed on the rover during the process of water sublimation, and they are small "mushrooms" after freezing.
In winter, the temperature drops to a very low level, and the groundwater is permanently frozen, so it is impossible to emerge from the ground again.
In fact, if you think about it casually, you can deny the conclusions of these "mushroom life theorists". Even under such rich organic matter and oxygen-enriched conditions on the earth, can these mushrooms flourish, grow so big, or grow on a smooth iron surface?
I don't know if there is any more in-depth information that these Mars "mushroom life theorists haven't disclosed, because the first-hand information I have is extremely limited, so my statement is just a family statement and personal opinion, for your discussion only, and not as any conclusion.
I am not afraid of these "mushroom life theorists" on Mars, and there will be more evidence to prove that their conclusions are correct in the future. If the evidence is conclusive, I'm glad to see it come true. What a great event it would be if life on Mars was really confirmed.
There are many detectors there now, and NASA's new detector "Perseverance" also brought a helicopter, and it has been successfully tested for a long time. I believe that more and more mysteries about Mars will be revealed, and whether there is life there will soon be revealed.
