282 Moon Palace Phase II Project
The ice reserves next to the Moon Palace have been calculated, about 200,000 tons, and there is a high possibility that there will be an additional ice layer deeper, but it is expected that the ice layer will be thinner and the reserves will be smaller.
There is no need to worry about water in the short term. The Yinglong No. 2, which the six new members ride, brings all food, and mainly uses various canned meat, seasonings, and chocolate.
Arrive at the Moon Palace to allocate the room for a while and have a meeting.
The small smelting plant has been built, and there are four key points for the next work.
The first item is that the smelter enters trial production.
The first phase is targeted to produce compressive glass.
All smelting activities on the surface consume oxygen, which is different in space because gas resources are very short and all waste must be recycled and processed. After a complete process, oxygen will increase.
However, the equipment in the smelter is not perfect enough now, and most of the recovered oxygen cannot be purified to the medical level and can only be used repeatedly in the factory.
The materials used to produce glass come from two places.
One is an impact crater five kilometers away. This pit is relatively new, with a large number of vitreous crystals formed by high temperatures. The silica content is determined to exceed 80%, making it the material with the highest purity within the scope of exploration.
Another area is relatively close, a piece of bauxite, four kilometers away from the base.
Journeys on the moon are different from those on the surface. They are all large stones with relatively more complex compositions. If placed on the surface, industrial utilization will not be given priority.
As a lively metal, aluminum can be made into alumina glass. Its glass is actually pure alumina, but it is transparent, so it is called glass.
Its strength is higher than bulletproof glass, and the ground production cost is about four to five times that of bulletproof glass. Generally, armored vehicles are reluctant to use it.
In a vacuum environment, the cost can be considered later, and it is easy to use first.
Ordinary compressive glass is a branch of tempered glass and is generally used in high-pressure containers, instrument surface panels, high-pressure pipeline observation windows, etc.
Due to the nature of the glass itself, it cannot be made too large. According to calculations, as a monthly greenhouse, a single piece can only be 12mm thick and six square meters. It cannot be spliced in the middle, and structural parts must be used for stability.
With more structural parts, it affects the light transmission rate of the glass greenhouse. The polar ambient light is already a little worse. If the light transmission rate continues to decline, more artificial light is needed to promote plant growth.
The strength of alumina is much greater, not only can it be made larger, but the connection structure can also be used in the airtight direction.
Another difference is the process.
The only industrialized production method of large-area flat glass is float production. It pours the glass solution on the tin solution, and naturally flattens the lower plane through the buoyancy and the huge tension of the metal solution, and then scrapes the upper plane flat and allows it to stand to eliminate fine lines.
The production of float glass requires huge tin solution tanks to be continuously produced. The month is manifested in the obvious lack of that condition. A floating workshop that has been built can only produce glass with a total area of more than ten square meters at a time. After being cut into a rectangle, it will be less than ten square meters. Because the moon's gravity is small, the floating production time will be longer, and it will not be produced in one day.
The situation of alumina is slightly better, but it is not the main production target of the factory itself. The production capacity is about 200 square meters per day based on the area. Using the bauxite discovered now, the production of alumina is more than a dozen raw material processing processes than the production of glass. In addition, aluminum purification itself is a huge energy consumption link, and the overall power consumption is about seven to ten times that of glass.
According to the results of a team of ten people and the surface meeting, it was decided to use the aluminum ingots sent from the soil balls as raw materials first, first produce alumina glass of several hundred square meters, build a glass greenhouse, and hand it over to botanists for use.
The second work is the expansion of the Yue Palace Base and its ancillary facilities.
The total area of the Moon Palace is only more than 300 square meters. Since then, it has been busy and has not had time to expand. Now there are ten people, and there will be more in the future. It is inevitable to expand.
This work was completed by the robot team before the six-person group arrived, but in the lunar gravity environment, the robot team also had a lot of work that was not easy to do.
According to ground instructions, a new building will be built this period.
This building is based on information collected by early robots and has been professionally designed and scientifically proved. The aerial view is generally "l" in shape, covering an area of nearly 500 square meters, with some viewing curves, and these viewing windows will also use alumina glass.
The first phase of the new building is four floors. It is a patio-style hall when entering from the fifth-section entrance and exit. You can try to jump directly to the third floor with good bounce ability.
Considering the response to the gas leakage crisis, pressure-resistant doors are installed between the hall and all aisles, and when necessary, each part of the building can be closed in different areas or in turn.
When the hall is closed, a new type of equipment used on the gantry spacecraft is used, a canned space suit storage cabinet and pressure relief chamber.
The usage is slightly different from the spacecraft. The emergency cabinet in the new building can be manually set to open the opening direction. The astronauts can open it on the hall or any side of a certain area, put on a space suit and drill into the cabinet, and then come out from the other side of the wall after decompression.
In addition, there is a lounge less than 20 square meters in each area, which can be opened on the upper and lower floors as an additional escape passage. The lounge has been additionally enhanced and is equipped with a separate air pressure management system, which can maintain a standard air pressure of 0.3 to 0.5 when the entire building is out of pressure.
The new building has put a lot of effort into safety, and even left room for additional floors, which can be expanded to seventh floors.
The fifth to seventh floors are the second phase of the project. Before the completion, the new building will not have its own signal antenna, and can only exchange data from the old building through optical cables.
The construction of such a building on the lunar month is quite large, and it is unrealistic to use light metal and ceramic prefabricated parts. It will be the first time that concrete is used on the lunar month.
The concrete needs to be moisturized and heat-insulated during solidification, and the robot has built three concrete prefabricated workshops in advance.
This kind of prefabricated workshop is a bit like a kiln, which uses external equipment to control the temperature during solidification. After the time comes, the remaining gas is extracted with a pump and directly open a wall for subsequent use.
The cement used will be produced in the factory area, most of which are semi-finished products sent from the surface, a small part of the active ingredients in the aluminum ore are added, and the volcanic ash-like substances harvested a few kilometers outside the monthly surface, and the sand and gravel parts of the concrete are taken locally.
Because all kinds of conditions cannot be compared with the ground, the project is expected to take half a year.
The time span is long and the old building is obviously not enough, so there are also expansion plans there, mainly completed by robots, and the expansion covers an area of 100 square meters. The interior includes floors and layered bedrooms, which will increase by less than 220 square meters in total.
The old building will be expanded for several days when it is opened. At that time, people will live on spacecraft and there are already a certain scale of crops in the old building, so they must also try to preserve them.
The aforementioned glass greenhouse is also part of this phase of construction project. In addition, there is an important ancillary facility, the serious spacecraft lands on the apron, but the project will not be opened until the factory starts metallurgy.
Whether all the work can be completed in a year depends on the support on the ground.
The third task is transportation and engineering machinery.
Now that I want to work, I rely on my feet or robot tracks to run around. The demand for transportation is imminent, and subsequent projects also require greater mechanical equipment support.
The minimum temperature on the lunar surface can reach more than minus 160 degrees. Rubber must not be exposed to the equipment. The destructive power of the lunar soil is also relatively strong due to low gravity. It is a completely different load system from the ground.
Early experiences of vehicle such as the lunar rover and the Red Star rover can be used as a reference, but they cannot meet the requirements of manned and construction.
In order to seize the time, after the ground completed the early demonstration and the experiment of the ground reduction model, it decided to complete the subsequent work in a coordinated manner of heaven and earth.
The first batch has three models, one roaming car and two engineering cars.
All the components related to the manned rover have arrived and are manually assembled by engineer-type astronauts on the lunar watch.
Two roaming vehicles have ten wheels, with sealed cabins and no toilets. When you go out for a long time, you still have to use traditional aerospace methods (diapers, bags) to solve the three emergency measures.
It is equipped with a radiation thermoelectric battery and a solar panel with a power generation capacity of 200 watts to ensure that day and night changes will not affect the range too much, and the full range of power is 400 kilometers.
Four hundred kilometers, supported by hexapploid sodium batteries, seem to be very few, but this is the moon, but there is no expressway, and in order to ensure the safety of tools and equipment space and vehicle, it is not suitable to put too many batteries.
The rover will be mainly used for drilling holes on the surface of surrounding areas, and subsequent supporting equipment can ensure that it can obtain rock formation samples at a depth of 100 meters.
Once the car is available, as for whether it is easy to use, how to modify it in the future, it still requires the joint efforts of heaven and earth.
The last job is to use electricity.
In a vacuum environment, electricity is the basis of survival. Without electricity, even oxygen is a problem. However, as a project, this is the simplest. After all, it is impossible to produce power generation equipment by itself in the short term, and it depends entirely on transportation.
There are only two sources of electricity on the lunar surface, solar energy and nuclear energy.
The micro-nuclear power unit specially developed for space and lunar meter is still under test. The layout of solar energy is not technically difficult at all, just follow the delivery progress.
However, in the polar regions, if you want to rely on solar energy to maintain the entire factory area and other aspects, the area required for layout is very large, and the span of day and night is larger than that of other regions. The weight of energy reserve equipment will occupy a large amount of transportation and loading.
So whether it is for the subsequent material circulation system or more people entering the future, they will eventually rely on nuclear power.
The "Dragon Ball" nuclear power unit that is being debugged on the surface is developed based on new nuclear power technology. It burns not boiling water, but steam.
During the entire process of the dragon ball running, the steam will not condense into water, and the temperature will be between 400 and 700 degrees.
The experimental unit does not include high-pressure vapor and fuel units, with a total weight of 50 tons and a power of 5 megawatts.
The power is very small. With the existing nuclear energy technology reserves in C country, it is not impossible to make 40 megawatts in 50 tons. The main concern is that this thing can only be transported as a whole. The vibration to the body during transportation may cause the risk of reducing reliability.
