Apollo landing on the moon is one of the greatest human history, although it has been more than 50 years. Armstrong’s signature footprints remain there forever, and never change. It’s just that the moon has no atmosphere, let alone the wind. But more important than this footprints is a bag of feces.
Maybe many people will have doubts, why is it feces? Yes, on the way to the moon, our astronauts pulled Baba on the moon, and then left this Baba in space, so that human beings can better study the future.
The bag is still there, but no one knows what happened to it, but some people will wonder why they want to study the Baba belt that astronauts were still in space more than 50 years ago? Human excrement is uncomfortable, but 50% of it is made up of bacteria, which means life. All this is a perfect ecosystem. After all, there are more than 1000 kinds of microorganisms in our intestines. In the past 3.9 billion years before us, the earth has cultivated these bacteria step by step, and we have been born from them. But at this time, the moon is still on the rise It’s still a barren land with no vitality.
When Apollo 11 landed on the moon, human excrement, urine, food residue, vomit, saliva and so on all contain various microorganisms, which also exist here. Today, 50 years later, all of these have become a hot natural experiment of NASA.
If this experiment can be further studied, it will be a big sensation.
These garbage are the highest content of fungi, bacteria and viruses on the earth, and the best preserved. After all, we all know that fungi are very tenacious, which means that this is another kind of microorganism that may survive.
In fact, the harsh environment has been repeatedly emphasized, and from all aspects, the earth is so suitable for human habitation, but the moon is on the contrary. First, it has no magnetic field to deflect cosmic radiation. Cosmic radiation makes it difficult for all life to survive. Second, because there is no ozone layer, it can not absorb the ultraviolet rays of the sun. The vacuum environment on the earth is not suitable for life at all, because there is no oxygen, nitrogen, carbon dioxide, and so on. Third, there is no atmosphere on the moon, so the temperature difference between day and night is a problem – for example, it is minus 180 at night If the temperature difference is about 300 degrees, can these bacteria and fungi survive?
Now NASA scientists have mentioned that in these closed fecal bacteria, they need to return to earth again, and scientists have also made great contributions. But the first thing to do is to make sure that the bags of these excrement are completely sealed. Once the sealing is not perfect, they will directly become dry Baba. And because of the repeated sharp temperature difference, they may rupture.
There is a kind of spore bacteria in the Arctic, which revived after freezing for thousands of years. If Baba bacteria on the moon is in a similar situation, in fact, the research value is remarkable. If it can be assessed as the limit of life, it is of great significance for the future trip to Mars.
NASA astronomers say that all this will be true, then scientists have raised the question, is life on earth carried by some outer space or the excrement of extraterrestrial astronauts? Is Baba bag left by astronauts likely to be the beginning of a new earth like planet?
In fact, what we generally believe is survival of the fittest and natural selection. No popular theory of the origin of life involves the excreta of astronauts, but we have to discuss it from a scientific point of view. This idea is completely reasonable.
After all, microorganisms can survive on the moon, even in a dormant state. For various reasons, it may mean that those microorganisms can survive in the deep space for a long time, or even shuttle in the universe. If they encounter earth like planets, they can reproduce along the way and spread life, and culture will take place.
