Whether there are really other lives and other civilizations in the abyss of the universe that humans have not reached has always been a topic that humans continue to explore and imagine.
For Chen Mengchuan, he suspects that in the nearly infinite three-dimensional universe, not only does life and civilization exist, but there are even very many, and there are even many cosmic civilization orders, but humans have not yet stepped out or touched them.
The alien civilizations in the dream are so powerful and mysterious.
How many years has this alien civilization developed in the universe?
Hard to know.
But there is no doubt that it must have developed longer and longer than the civilization on earth.
Perhaps the pace of civilization is hundreds of years longer than that of human beings, maybe thousands of years longer, or even tens of thousands of years longer.
No one knows.
How powerful is such a civilization?
No way of knowing.
The only thing humans can do is to strengthen themselves, prepare for the coming war, and leave a fire.
Evening on Mars.
In a public R&D test area of the Six Flames Palace, many people were watching an aircraft in the test area on the fences.
"To what extent can this cold insulation layer withstand Europa's low temperature?" Chen Mengchuan touched the cold insulation layer material in the middle of the aircraft and asked a researcher next to him.
This scientific researcher's surname is Qian, and his name is Qian Jianghai. He was once affiliated with the Xia Science Academy, and later started his own materials business. The business was very large and he established offices overseas. Later, the company went bankrupt and I interviewed Tenzhi Technology as a scientific researcher. After joining Tenzhi Technology for more than one year, I quickly emerged and took on important responsibilities in Tenzhi Technology's materials research and development department.
"CEO Chen, the technology of this cold insulation layer is not just about the material, we also put a lot of thought into the structure. The innermost part of the cold insulation layer of the 9-layer structure is based on nuclear energy heating, which means that the external temperature is not easy to erode into the inside, and at the same time, it continues inside During the heating process, a lot of heat energy will be lost, but overall, it is not a big problem when working in a space environment of minus 200 degrees Celsius. At the extreme end, we have tested as low as minus 250 degrees Celsius, and it can still hold up and work normally."
"So, exploration in Europa should be no problem?" Chen Mengchuan smiled.
"In a short period of time, the problem should not be serious, but the details still need to be based on the actual situation." Qian Jianghai said relatively conservatively.
"Go and see Multi-Arm Crab."
"Okay."
Several people walked around the aircraft and saw the bloated Multi-Arm Crab in the door area on the other side of the aircraft.
The overall exterior structure has not changed much, but the interior has been greatly modified.
27 heating devices and 3 high-intensity energy conversion devices make Multi-Arm Crab's belly grow bigger. Each limb segment is also equipped with a cold insulation layer, and the overall look is like a big crab covered with downy hair. There are some cute paintings.
"On the limbs of these Multi-Arm Crab, in order not to affect movement, we will have less cold insulation layer on them, but based on a large number of graphene thermal conductive wires, the flexibility is not bad, and the thermal conductivity of graphene is unparalleled. We have tested the cold-bearing capacity of these Multi-Arm Crab, and it is very good. Basically, they can work stably in extremely cold environments."
Chen Mengchuan walked over and patted Multi-Arm Crab's joints and limbs. It was very thick, and the outermost layer felt a bit velvety when touched.
Through analysis and prediction of a large amount of data from NASA, the surface temperature of Europa is very low. The average temperature in the equatorial region is about between -150 degrees Celsius and minus 170 degrees Celsius. The temperature at the north and south poles is even lower, reaching the terrifying minus 220 degrees Celsius.
Because of such a low temperature, the entire surface of Europa Europa is filled with permanently frozen water, which is the permanent ice layer.
But under this permanent ice layer, due to the gravitational pull of Jupiter, Europa has tidal forces at work. The heat energy provided by this tidal force may keep the water under the thick ice layer on the surface in a liquid state!
This conjecture was originally triggered by a series of speculations about tidal heating, the slightly off-center orbit and the orbital resonance between Europa and the other Galilean satellites.
NASA has invested a large number of image reading teams in Galileo program. After analyzing a large number of images taken by NASA's Galileo and another exploration spacecraft Voyager, this image reading team deduced that the terrain features of Europa mean the existence of a subglacial ocean! This probability is very high, and it even just lacks an aircraft to fly to Europa Europa for confirmation.
Now Tenzhi Technology is going to throw this spaceship to Europa to conduct the final step of confirmation.
However, there is no doubt that the surface terrain of Europa is very complex. The scientific research under this complex terrain is also very difficult, and the test of Multi-Arm Crab is also great.
A small group of scholars in Europe who have studied geology and the space environment deeply explained that the chaotic terrain with very distinctive characteristics on the surface Europa Europa is also caused by the seepage of lower seawater from the surface.
However, this explanation is quite controversial and has been debated endlessly.
Most geologists studying Europa favor a theory known as the "thick ice" model.
Because they believe that even if there is such an ocean under the Europa Europa ice layer, it is almost impossible to have a direct impact on the surface, because the thickness of the ice layer is undoubtedly very, very thick.
But if you really want to calculate how thick the ice layer of Europa is, it is already a matter that requires on-site inspection to know the final result. Because of this, there are considerable differences in the estimates of the thickness of the Europa ice shell by different research teams. Some think it is a few thousand meters, while others think it is tens of thousands of meters.
This time, the Europa exploration spacecraft has a large partition. This large partition is equipped with a nuclear energy drilling machine. In the plan, the mission of this nuclear energy drilling machine is to drill as deep as possible into the core of the Europa. One of the purposes is to detect how thick the ice shell of Europa is!
Regarding the "thick ice" model, everyone at Tenzhi Technology is quite sure, because there are several huge impact craters on the surface of Europa Europa! These huge impact craters are the best evidence to support the "thick ice" model.
From the observation point of view, the largest impact crater on the surface of Europa is surrounded by several concentric circles. From the observation point of view, the crater is filled quite flatly with fresh ice.
Based on this phenomenon and combined with estimates of the heat energy generated by tidal forces, Tenzhi Technology and the NASA map reading team inferred that the thickness of the ice shell is relatively similar. They both believe that it is between 10 and 30 kilometers. This thickness is similar to the thickness of the Earth's crust, which means that the ocean under the ice may be as deep as 100 kilometers!
If life really existed in the subglacial ocean of Europa, this would be a huge ecosystem!
