Shi Keji and his teammate Li Jianxian drove an electric off-road vehicle along the way. The two of them still had some tasks for this exploration mission.

In addition to the geological conditions around the exploration base, there is also the task of finding rich mineral veins.

The moon's night is very different from the Blue Star.

On the moon, there are about 15 blue star days at night, which means the "day" of the moon is actually 30 blue star days.

This corresponds to the moon's orbital time. Due to tidal locking, the front of the moon is almost constant and can only face the blue star.

In the area exposed by the sun, the moon will be filled with the moon due to the moon's revolution. The moon's revolution here refers to the moon's revolution to the blue star, similar to the blue star's revolution to the sun.

In fact, if calculated according to precise calculations, the time of night on the moon should be slightly longer than that of the day, because the moon will be covered by blue stars, which is a lunar eclipse.

The lunar eclipse phenomenon causes the moon's night time to occur slightly longer than the daytime.

At this time, Shi Keji, Li Jianxian and the others will spend a long moonlit night in the dark moon sea wilderness.

The reason why we chose the moonlit period and went out to explore geology is mainly for safety. After all, the moonlit period is when facing the sun, so we should know that the moon's geomagnetic magnetism is relatively weak and is basically almost invisible.

Without strong geomagnetics, a magnetic cage protection field cannot be formed. Solar storms and charged particle flows can drive straight in unscrupulously.

This is also the main source of hydrogen, helium, nitrogen and carbon atoms in lunar soil.

The small electric off-road vehicle used in scientific research cannot be installed with a bulky artificial magnetic cage system, and can only use composite lead plates with a thickness of 0.15 cm to resist solar storms and charged particles.

However, if you encounter a solar storm with a disaster level of 10 or above, small equipment can easily be disturbed by solar storms, and even electronic equipment is damaged, scrapped, and endangering the lives of astronauts.

The disaster level of solar storms was established by the Space Administration for imitating typhoon levels, and is divided into 0 to 16 levels.

Normally, the moon without the protection of the planet's native magnetic cage will have a solar storm intensity of about 4 to 8 levels, and occasionally a level 9 to 11.

Levels 12 to 13 are the intensity that blue stars are affected, level 14 is a rare intensity in a century. Levels 15 to 16 can already endanger the entire blue star ecosystem, and even destroy the blue star ecosystem. It is a terrible disaster second only to the sun's helium flash.

In order to protect the life safety of astronauts, the lead composite board on the off-road vehicle is not 100% safe. Increasing the thickness of the lead composite board will cause the off-road vehicle to increase its weight and lose its original cost-effectiveness.

After thinking about it, the Space Administration made a compromise arrangement, which was to try to go out during the moonlit night and be a group of night owls.

The appearance of the electric off-road vehicle is similar to that of an armored vehicle, with two satellite communication pots added, and the proportion is a circle larger than that of an armored vehicle.

The reason for magnification of the proportion is mainly because the astronaut's exoskeleton spacesuit is a circle larger than the old-fashioned outboard spacesuit.

During the walk and stop, the two of them arrived at an area 42 kilometers away from Guanghan Palace Base on the third day.

Looking around, there is endless darkness, and the only clear land under the searchlight.

Shi Keji stopped the car and opened the special flatbed she carried with him. The off-road vehicle could directly connect to the communication satellite to achieve high-speed and high-throughput satellite communication.

Open the tablet, first locate the detailed location here, and then call up the detection database of the geological remote sensing satellite.

Shi Keji stopped to explore the location carefully, so he did not choose casually, but had done relevant data analysis in advance.

"Restraint yourself and detect the escape of radon 222." Li Jianxian said through the shortwave communication system.

"It seems we have arrived at the destination." After Shi Keji said that, he contacted Changong Space Station and asked the other party to mobilize a geological remote sensing satellite to cooperate with his exploration work.

Judging from the real-time remote sensing geological data at this time, the temperature in this area under the feet of the two people was slightly higher than that of ordinary moon seas.

Especially during the moonlit night period, when the sun is not exposed to the sun, the temperature on the moon's surface is minus 183 degrees Celsius.

The area under the feet shows a concentric circle temperature gradient layer, with a very obvious dividing line from minus 183 degrees Celsius in the outer layer to minus 27 degrees Celsius in the core.

The radius of this area is about 2.3 to 2.5 kilometers.

The radon 222 detected by Li Jianxian just now is a landmark element because generally speaking, radon 222 is derived from uranium decay, and the half-life of radon 222 is very short, only about 3.7 days.

Therefore, radon 222 is generally regarded as a landmark substance for underground magma activity. If radon 222 is found, it can be basically determined that volcanic activity exists in this area.

In fact, although the volcanic activity on the moon stopped on a large scale more than 3 billion years ago, it does not mean that it is completely dead.

At least after the establishment of Changong Space Station and the comprehensive lunar satellite system, remote sensing satellites detected 736 areas and 2,417 transient events occurred.

The so-called transient events are: local lunar blur, color changes (emitting infrared light) and brightness changes.

Most of these transient events are concentrated on the edge of the crater with fragile stratigraphic structures.

The location of Shi Keji and his two men at this time seemed to be a smooth road, but in fact, this was the location intersecting with the Yuhai during the formation of Hongwan, a typical hidden crater edge area.

Obviously, this is a "fire fountain" of underground magma. Although only two transient events were detected here before, once 1.7 seconds and once 2.4 seconds, radon 222 was detected here and the obvious concentric radius of the ground temperature, which proved that this was a "fire fountain".

The two of them came here to explore, and their purpose was not simply to look at it.

Because the moon base must develop large-scale industries, one problem must be solved, that is, the energy problem.

At this stage, the controllable nuclear fusion power station is huge in size and has not escaped the limitations of boiling water. It is still obviously immature to be used in lunar bases.

As for solar power plants, we can consider it, but solar panels face several major problems on the moon.

First, the electrostatic adsorption of Yuechen, which can be solved through technical means.

The second is the aging problem. In the lunar environment, the power generation efficiency of solar panels will be improved, but dense high-energy rays, charged particle flows, and neutron flows will cause rapid aging of solar panels.

Especially the possible super-strong solar storms are a fatal threat to solar panels. The industrial areas require a huge amount of electricity and require stable power supply.

The moon's moonlight alternating time is as long as 15 days, which is not conducive to the large-scale application of solar panels.

The toner energy storage power station is not suitable for the environment on the moon because the moon does not have a clear atmosphere and does not have a large amount of carbon dioxide, methane, etc.

As for the carbon 14 nuclear decay batteries currently used in the base, small-scale power supply is OK, but for industrial production, it is obviously a difficult situation for nuclear batteries.

Therefore, the Space Administration had no choice but to focus on the moon's geothermal energy, hoping to build geothermal power stations to support the early industrialization of the moon.

Just as Shi Keji was busy exploring this hot spot, the signal of the tablet computer in his hand suddenly became intermittent.

Seeing this scene, he frowned.
