Lead-zinc mine is very important for lunar base, for example, radiation-proof lead alloy plate is the most suitable material
At present, Blue Star Lunar Materials Research Institute has designed a processing chamber to prepare foam silicon steel skeleton and then press lead material to form composite plate.
The lead plates to be arranged are mainly for protecting solar wind, mid-stream and mass flow.
Although Guanghan Palace base has a magnetic cage protection system, it is best not to unify the chips in a dangerous environment base.
In case there is a problem with the magnetic cage protection system and a solar storm happens, many equipment in the base may be affected.
This is also why the space capsule of NASA outpost 1 base will be overweight because their shell is covered with a layer of lead plate to enhance the ability of the space capsule to resist solar storms.
However, the base of Guanghan Palace, a daring artist, adopted a magnetic cage scheme, and the shell thickness of the body cabin was cut to about 3~ cm.
Of course, if the lead-zinc mine is not found, the Space Agency also has a backup plan, that is, the cabin covering soil plan.
Lunar soil covers the surface of the space capsule to form a protective layer.
Chapter five hundred and ninety-six The moon (7)
Shi Keji and teammate Li Jianxian drove the SUV all the way forward carefully, and this time they explored some of them.
In addition to the geological conditions around the exploration base, there is also the search for rich veins.
The moon night is very different from the blue star.
The moon night is about 15 blue star days, which means that the moon "one day" is actually three blue star days.
This corresponds to the fact that when the moon revolves, the front of the moon is almost constantly facing the blue star due to tidal locking.
However, the solar irradiation area will be full of moons and full of moons due to the revolution of the moon. Here, the revolution of the moon refers to the revolution of the moon against the blue star, which is similar to the revolution of the blue star against the sun.
In fact, according to the precise calculation, the night time of the moon is slightly longer than the day time, because the moon will be covered by blue stars, that is, the eclipse phenomenon.
Eclipses make the moon appear slightly longer at night than during the day.
At this time, Shi Keji and Li Jianxian will spend a long moonlit night in a dark moonlit wilderness.
The choice of moonlit period to go out for geological exploration is mainly for safety. After all, moonlit period is the time to face the sun directly. You should know that the moon’s geomagnetic field is relatively weak and the base is close to the state.
Without strong geomagnetism, a magnetic cage protection field can be formed, and solar storms and particle-laden flows can drive straight in without fear.
This is also the main source of hydrogen, helium, nitrogen and carbon in lunar soil.
The scientific research makes it possible to install heavy artificial magnets by means of small mobile off-road vehicles, so that the 15 cm thick composite lead plate can resist solar storms and particles.
However, in the event of a solar storm with disaster level 1, small equipment will be easily disturbed by the solar storm, and even equipment will be damaged, scrapped and the life of astronauts will be endangered.
The disaster level of solar storm is set by NASA in imitation of typhoon level, which is divided into 0 ~16 levels.
Usually, there is no planetary primary magnetic cage to protect the moon. The solar storm intensity is about 4~ level, and occasionally it appears 9~11 level.
And 12~13, the blue star will be affected. The intensity of 14 is rare in a hundred years. The intensity of 15~16 is already dangerous, and the entire blue star ecosystem is destroyed. The blue star ecology is a terrible disaster second only to the solar helium flash.
In order to protect the life of astronauts, the lead clad plate of off-road vehicle is not 100% safe, and increasing the thickness of lead clad plate will lead to the weight increase of off-road vehicle and lose its original cost performance.
After thinking about going to NASA, I made a compromise arrangement, that is, I tried to go out as a group of night cats during the moonlit period.
The shape of the SUV is almost the same as that of the armored vehicle, except that there are two more satellite communication pots, and the proportion is one circle larger than that of the armored vehicle.
The scale to be enlarged is mainly due to the fact that the astronaut exoskeleton space flight is larger than the old extravehicular space flight.
On the third day of stop-and-go, they came to the area 42 kilometers away from Guanghan Palace base.
Looking around, there is a dark searchlight with only a clear land.
Shi Keji parked his car and took a special flat-panel off-road vehicle with him, which can be directly connected with communication satellites to realize high-speed Qualcomm satellite communication.
First locate the detailed location of this place and then call up the geological remote sensing satellite detection database.
Shi Keji stopped to carefully explore the location, and naturally he did not choose it casually, but did phase data analysis in advance.
"Self-denial has detected the escape of radon 222," Li Jianxian said through the short-wave communication system.
"It seems that we have arrived at our destination." Shi Keji said that he and themoon jointly asked the other party to mobilize a geological remote sensing satellite to cooperate with their exploration workers
Judging from the real-time remote sensing geological data at this time, the temperature in this area of two people’s feet is slightly higher than that in the ordinary moon sea.
Especially in the moonlit period, when there is no sunlight, the surface temperature of the moon is 13 degrees Celsius.
The foot area presents a concentric temperature gradient layer, and there is a very clear dividing line from the outer layer of minus 13 degrees Celsius to the core of minus 27 degrees Celsius.
The radius of this area is about 23~25 kilometers.
Just now, Li Jianxian detected that radon 222 is a symbolic element, because generally speaking, radon 222 decays through uranium and its half-life is very short, about 37 days.
Therefore, radon 222 is generally found by the landmark substance of apparent magmatic activity, and the volcanic activity in this area can be determined based on radon 222.
Although the volcanic activity of the real moon stopped on a large scale more than 3 billion years ago, it does not mean that it is dead.
