Five days passed unconsciously.

The drill bit of detector 15 is still going on.
At this time, the drill bit has been drilled to a depth of 436 meters.
Suddenly detector 15 trembled slightly, and the resistance of the drill bit seemed to disappear.
The car super brain program runs automatically.
It took less than 20 seconds to try to operate the drill bit and continue drilling. The drill bit has been exploring for 136 meters before it encountered new resistance.
half an hour later
Blue Star Australia Dasha Aerospace City
The Mars Exploration Bureau of the Ministry of Space has set up Dasha Space City, and their work is specifically responsible for Mars exploration.
The Mars 15 probe finally took control of the Mars Exploration Bureau.
After half an hour of continuous transfer for several times, the latest status data of detector 15 finally returned here.
A worker who specializes in tracking the No.15 detector looked at the latest feedback data and had a small discussion.
After reading the data, geologist Huang Kaixuan revealed a trace of meditation. "The stratigraphic area of 43,621 ~ 45,457 meters is obviously a cave fault."
"From the samples taken out, this is an underground river," said another researcher.
Huang Kaixuan pointed to the first line of data. "But the temperature has reached 23 degrees Celsius, which is a quite warm environment and liquid water …"
It’s that he hasn’t finished yet.
Another worker staring at the communication screen opened his eyes wide and said, "There’s something new!"
"What did you find?"
The worker quickly replied, "Thirteen organisms with a length of about 23~2 cm were found from the extracted water body, which are similar to tadpoles."
Zhang Maosheng, another biologist, rushed to stare at the page and sent back various photos after being photographed by detector 15.
These photos hardly need to make the microscope mode make people see the Chinese creatures clearly.
A creature similar to a tadpole appeared in front of everyone.
"It should be a aquatic creature similar to a blind fish," Zhang Maosheng initially judged.
Another biologist touched Ba. "According to the data, there are other microorganisms and another paramecium-like creature."
They were not too surprised after a surprise.
Because the biological things on Mars can be inferred by fluorescent fungi.
Now that microorganisms have been developed, multicellular organisms are also possible.
According to the analogy of blue star biosphere, the conditions for producing carbon-based organisms can be summarized as "liquid water" and "heat"
There’s nothing wrong. It’s that simple.
The conditions for the birth of carbon-based organisms are liquid water and heat, while oxygen, gravity and radiation are not certain.
For example, anaerobic bacteria do not need oxygen; There are also blind fish in the small ecological enclosure around the black chimney on the seabed.
These are special cases.
If there is liquid water and continuous and stable heat, it is possible to form a small ecological circle
Although the ground atmospheric concentration of Mars is very low and the carbon dioxide content is very high, the base is not rich in oxygen.
At the same time, there is no liquid water on the surface of Mars, and the solar radiation heat is much less than that on the blue star side.
However, many people forget that there are two sources of heat in the planetary system, one is from the irradiation of stars, and the other is the decay heat of the earth’s core.
It is true that Mars receives very little solar energy, but the depths of Mars still have geothermal energy.
If geothermal energy happens to meet both sides of underground rivers, it is possible to form a special environment suitable for biological reproduction.
Obviously, the drilling results of probe 15 verified this conjecture.
Zhang Maosheng said with bright eyes that "the underground river of Mars and geothermal energy combine to form their own ecological circle, which means that it is the same possibility in similar planets."
"In this way, the natural satellites of Jupiter and Saturn are more likely to live, such as Europa," Huang Kaixuan reasoned according to the planet data he knew.
The fact may be as Huang Kaixuan guessed.
Mercury and Venus in the solar layer form a stable carbon-based ecosystem because of too much solar radiation, very high body temperature and insufficient geological activity.
On the contrary, the planets in the middle and outer layers of the sun may have life except gaseous planets.
For example, the surface of Europa, a famous natural satellite, is an ice layer with a thickness of several thousand meters, and the ice layer is a sea of possible liquid water.
In recent years, the observation data have also repeatedly monitored Europa’s hot fountain phenomenon.
This means that the active geothermal energy of Europa ice is not less than liquid water.
Both of them constitute a set of primary ecology, and it is more than enough to cultivate some simple microorganisms.
And there are many planets like Europa in the real universe.
There are many such planets in the sun alone.
To some extent, it is also a controversial topic whether the life of Blue Star originated in the present.
After all, the probability of finding surface microorganisms and organic matter in a list of asteroids captured by the Federation is not small.
In this case, it is possible for alien creatures to spread to other planets with the activities of asteroids.
And in the process of broadcasting, it happens to meet a species of life that is relatively suitable for the environment, and that planet will take root and sprout.
Chapter seven hundred and forty-six Abnormal
It has been two weeks since the Mars 15 probe drilled, and the drill bit has already reached the limit depth of 1 meter.
There is nothing unexpected in the analysis of rock samples collected during drilling.
But the 436~454 meters underground river has brought many new discoveries to the scientific community.
At present, 5 kinds of multicellular organisms and 24 kinds of microorganisms have been found in this small ecological circle.
Among the five kinds of multicellular organisms, there is a discovery of "Martian tadpole fish", and the other four species are "hot spring brown algae", "red jellyfish", "hydrozoa" and "stone-sucking insect".
These multicellular organisms and more than twenty kinds of microorganisms together form this small ecological circle.
