Thickening the lead plate scheme means transporting a batch of lead plates and the lead body is extremely heavy.
The plan of covering the soil in the base needs to transport an excavator.
Of course, NASA can also choose the beggar scheme to send astronauts a shovel to cover the space capsule manually, which is too low cost-effective
The last plan-the ground base plan needs more quantities, and NASA estimates that it can’t grasp it.
NASA is in a tangle.
On the other hand, NASA is advancing the construction of the lunar base step by step.
With the first foam silicon steel synthesis cabin put into use, although it is a small industrial cabin with a daily output of about 100 tons, it is a leap-forward progress for Guanghangong base, which used to rely on scientific research cabin to produce materials.
Less from the current moon base materials should no longer be 100% dependent on soil.
The first batch of foam silicon steel produced is custom-made tracks, sleepers and foundation reinforcement columns, which are used to lay railway building materials.
For the moon with low gravity and obvious atmosphere, the ground transportation and mining railway is more cost-effective than the blue star railway, and the speed limit and effective load can be doubled.
Therefore, laying a railway to form a lunar base is an important means to expand around.
The transportation from Blue Star to the lunar module has also changed from the former scientific research module owner to the industrial module and living module.
Shaoguang Cold Palace Base needs to establish a set of relatively perfect building materials industry and hardware industry, which can produce building materials, hardware and outer shell of space capsule by themselves.
At that time, the construction speed of the lunar base that needs soil sensors, components and precision parts will rise by an order of magnitude.
For example, the weight of skeleton, shell and composite protective layer in the space capsule accounts for 7~% of the whole space capsule, but these things are not too high in technology but essential.
Only by realizing the industrialization of the moon can the moon base quickly become a moon city.
Next month, Earth will launch three CNC processing chambers so that Guanghan Palace Base can further process the produced materials.
In recent years, NASA has also envisaged that additive manufacturing similar to 3D printing will face a series of technical problems.
The difficulties in additive manufacturing include slow processing speed, relatively single material, low overall strength and relatively small processing size.
Moreover, there is another problem in the manufacture of the moon by adding materials, that is, the problem of raw materials
At present, a large part of the raw materials for additive manufacturing are organic compounds, and the abundance of carbon on the surface of the moon is not high, and there are no natural organic minerals.
To come to the space agency to develop the lunar industry is to get rid of the dependence on soil materials. It is obvious that the large-scale production of soil should be based on raw materials and materials, which is not in line with the lunar development strategy for a short time.
The industrialization of Guanghan Palace base is progressing in an orderly way.
Shi Keji and Li Jianxian’s exploration of No.1 thermal well in Pingyuan is also going very smoothly.
According to the preliminary exploration, this hot well is about 32~35 meters, and the temperature at this depth is just suitable for geothermal generation.
The design of lunar geothermal power generation is not the same as that of Bluestar. The plan of giving up the water-heating mode is to adopt a single temperature difference generation system.
Chapter five hundred and ninety The moon (9)
The sudden solar storm disrupted the rhythm of NASA and China Space Administration, and both sides could respond passively.
Human beings are still too fragile, and the level of science and technology has not reached the first-class literacy level. Even if individual science and technology are super strong, the comprehensive strength of Greater China will reach at most 94, which is still a long way from the first-class literacy level.
Nowadays, human beings have no 100% hard resistance to the earthquake, volcano and climate of their home planet, let alone the cosmic disaster of solar storm.
Once the intensity of solar storm exceeds 12, it will become too rubbish for a spacecraft without magnetic cage protection to rely on the protective layer and triple redundancy system to resist it.
But none of these three schemes can be easily completed.
