In Fang Hong's previous life, humans not only confirmed the existence of life in the underground ocean of Enceladus, but also that the structure of life was more complex and diverse than scientists predicted. Before confirmation, it was generally believed that the existence of life was only microorganisms.
But in fact, the life forms at the heat source on the seafloor of Enceladus have evolved to centimeter-scale sizes, and these are not microorganisms.
It has also been confirmed that the ecological environment at the seafloor heat source of Enceladus is covered with a thick carpet of bacteria, which is surprisingly similar and has convergent evolutionary properties with the early evolutionary stages of marine paleontology on Earth.
With in-depth exploration and research, scientists from Fang Hong's previous life confirmed that life on Enceladus is older than the earth. They also confirmed that life on earth did not originate on its own, but that the seeds of life on Enceladus were sown through asteroids.
Earth.
Moreover, in Fang Hong's previous life, it was not only confirmed that life exists on Enceladus, but before confirming the existence of life on Enceladus, it was also confirmed that life also appeared on Mars billions of years ago, and it was very prosperous and evolved.
Very complex life forms emerged.
It's just that life on Mars did not evolve intelligent life, and even life on Mars was completely extinct before it landed in the ocean. The cause of the mass extinction of life on Mars was a series of chain reactions caused by the cooling of the planet's core.
After all, the volume and mass of Mars are too small, which causes the core of Mars to cool too quickly and cannot maintain it like the Earth. After the core cools, Mars' global magnetic field also disappears. You must know that the magnetic field can effectively shield the solar wind.
High-energy particles that protect the atmosphere from solar wind erosion.
Without the protection of the magnetic field, the Martian atmosphere disappeared, and the global ocean on the planet's surface continued to evaporate and peel off, and was eventually blown away by the solar wind into the vast space. The evolution of life on Mars ended prematurely before landing, and Mars finally evolved.
It became what it is today.
But the core of Mars did not cool down 3 billion years ago. At that time, Mars was a world full of life. If the core did not cool down and continued to this day, perhaps life on Mars could eventually evolve into intelligent life.
Fang Hong clearly remembered the series of projects that humans in his previous life had carried out to explore Mars, and discovered that life on Mars has not been completely extinct. There are still microorganisms in the strata in some areas, and when he later landed on Mars for further exploration, he also discovered that life on Mars has not been completely extinct.
Paleontological fossils from Mars have been excavated from the strata and are dated to be over 3 billion years old. This is direct and irrefutable proof that Mars was a world where life flourished 3 billion years ago.
And it proves that the "convergent evolution" attribute of life also applies to this natural law between different planets.
Subsequent scientific research has shown a lot of evidence that the origin of life on Earth is the seeds of life brought from Mars 3.5 billion years ago, and that life on Earth today is a continuation of life on Mars.
However, life on Mars did not originate from Mars, but from Enceladus. This has been recognized by scientists in Fang Hong's previous life.
However, there is a huge controversy as to whether life on Earth originated from the continuation of life on Mars or from Enceladus. Scientists have been arguing about this for more than ten years without reaching a consensus. Fang Hongdu has been reborn in time and is still arguing.
Some scientists believe that life on earth originated from Enceladus. The ice volcano eruption of this planet ejected the basic life structures of the seabed into outer space. It happened to be carried by celestial bodies such as asteroids or comets that passed by on the way. In the end, the asteroid
Or the comet flew towards the inner solar system and was eventually captured by the earth's gravity, thus bringing the fire of life to the earth.
Life on Mars was brought to Mars from Enceladus in the same way. More than 3 billion years ago, Mars was more suitable for the evolution of life, which promoted the prosperity of life on Mars.
After all, the solar system billions of years ago was not as stable as it is today, with asteroids flying around and bumping into each other.
But another group of scientists who oppose this statement believe that the transmission link of life first spread from Enceladus to Mars, and then spread from Mars to the Earth 3.5 billion years ago, allowing Martian life to continue, evolve and flourish on the Earth.
.
Scientists who support the Mars origin theory of life on earth believe that the probability of two asteroids appearing at the same time carrying life from the distant Enceladus to the earth and Mars is higher than the probability of life from Mars spreading to the earth. Compared with the two probabilities
The latter is more likely.
However, scientists who support the origin of life on Earth from Enceladus believe that if this is true, then there should be a large number of frozen microbial remains scattered in Saturn's E ring, which should have been detected by Cassini long ago.
It was only right that the instrument was discovered, and subsequent in-depth research on Saturn's E ring also found that it was not enriched with much material for life structures.
For this reason, the two academic schools were quarreling over whether life on earth originated from Mars or Enceladus. No one could convince the other. The two schools were still arguing until Fang Hong traveled through time and was reborn.
Fang Hong estimated that in this life, after the fossil sites of ancient life on Mars are discovered later, and the existence of life in the underground ocean of Enceladus is also confirmed, the question of whether the origin of life on earth is Mars or Enceladus will mostly remain in the scientific community in this life.
The noise will continue.
Scientists are very concerned about whether life on earth originated from Mars or Enceladus, but Fang Hong doesn't care where it originated. Now Fang Hong only cares about the existence of extraterrestrial life, and that is enough.
Proving the existence of extraterrestrial life, even if it is just a single-celled organism, is of great significance to the construction and popularization of the values of a "community with a shared future for mankind", which is why Fang Hong will spare no effort to promote space exploration.
Obviously, Magnesium West's Cassini probe did not find evidence of life on Enceladus, otherwise it would have become explosive news.
For the scientists present, it is still unknown whether life exists on Enceladus and Mars, but in Fang Hong's eyes, it is known and confirmed, and only solid evidence is needed.
In the "Nine Days to Starry" project, Fang Hong only focused on investing in and prioritized the launch of the two major projects of "Mars Exploration" and "Saturn Exploration", putting aside the relatively closer Jupiter detection. One of them he hid from outsiders.
The purpose is to find evidence of the existence of life.
The next mission goal in the field of space exploration is also very clear, which is to find evidence of the existence of extraterrestrial life, solid proof, and then make this explosive news public to the public, establishing an absolute mainstream position for the value of building a "community with a shared future for mankind."
The Saturn exploration mission took off as early as 2016. Now four years have passed and it is still on its way to Saturn. Its main mission is to detect Enceladus and Titan. It is still difficult to fly to Saturn.
It will take about 4 years, that is, until around 2024, after it is parked in the orbit of Saturn, it will probably take a lot of time to produce actual results.
Obviously, nothing can be expected from the Saturn exploration mission in the next five years.
What Fang Hong is most concerned about right now is the Mars exploration mission that is closer to the earth, because this project will soon enter the Mars orbit on February 10, which is 12 days later.
With good luck, major results will be made this year, and microorganisms may even be discovered in the Martian strata. It is not impossible to even discover paleontological fossils from Mars that are more than 3 billion years old.
