Tell me about the inspection station project, when it is expected to be completed. Wu Hao changed the subject and asked Zhou Xiangming.
Hearing Wu Hao's question, Zhou Xiangming responded immediately: "At present, it is estimated that the first phase of the research station will take two years to complete, and at least three more lunar cargo spacecraft will be launched.
However, our theme building will probably be completed next summer, and then it will be transferred to the construction of the interior and the supporting facilities of the research station. This process is relatively slow, just like decoration. It may only take three days to build a one-story house, but it may take several months to decorate a one-story house.
The same is true for the research station. What our lunar soil 3D printer prints is just a shell. "
Need three more cargo ships? Zhang Jun couldn't help asking when he heard the words. Now two have been launched, and three more will be five lunar cargo spacecraft. This scale of transportation is probably more than other research stations that do not use lunar resources for construction.
You know, their lunar cargo spacecraft can send about ten tons of materials to the moon at a time, and these five spacecraft can carry 50 tons of materials. The cargo carrying capacity is amazing.
Seeing Zhang Jun's reaction, everyone laughed, while Zhou Xiangming smiled wryly at Wu Hao and said, "This is already a very conservative estimate. You must know that the first phase of our lunar scientific research station It covers an area of more than 1,000 square meters, and its construction area is more than 500 square meters. This scale can be said to be unprecedented.
It is far from being comparable to those companies and space agencies that have shipped a few landers and called themselves research stations. "
Hearing Zhou Xiangming's words, everyone laughed. They are clear about the lunar research station that this guy is talking about. To put it simply, it refers to those companies whose aerospace strength is not too strong, but they have swollen faces to pretend to be fat, showing their strength as a big country or company.
They couldn't come up with a real lunar scientific research station, so they launched a few super-ups, built a small scientific research station with super-landers, and called it their lunar scientific research station.
Seeing everyone smiling, Zhou Xiangming continued: "These five spaceships are used for the construction of the scientific research station, and if we want to accommodate personnel, we need at least two to three spaceships to transport supplies to the research station.
Such as food, water, air, and a series of other consumables, etc., these are the necessities of life for personnel. Without them, people may not be able to last even a day. "
"Can't water and air be obtained on the moon?" Zhang Jun asked doubtfully.
Everyone laughed at this. Yu Chengwu chatted to him and explained: "That's right, we can indeed obtain water on the moon, and we have collected a lot of water through the evaporation and condensation of the heat generated by the operation of two lunar soil 3D printers.
But these are far from enough. Living and working on the moon requires a lot of water resources. The water resources we obtained on the moon in the early stage are definitely not enough, so we must supplement some from the earth.
In the later period, with our development, the amount of water resources obtained on the moon increased, and after meeting the needs of our research stations, there was no need to transport water from the earth.
In addition, the water is not only for daily drinking, but also for life, production and even scientific research. For example, if we want to build an ecological farm, whether it is soil cultivation or soilless hydroponics, it cannot do without water.
As for the air, although what we really need to breathe is the oxygen in the air, too much oxygen is harmful to the human body. Therefore, the oxygen content must be guaranteed within a certain range, but we cannot only inhale oxygen, but also need nitrogen to dilute the oxygen and participate in the expansion and contraction of our lungs.
On the moon, oxygen can be obtained by electrolyzing water, but nitrogen is not easy to obtain, so it still has to be transported from the earth.
Fortunately, we humans do not consume nitrogen, so the nitrogen will basically not be consumed, only the oxygen in the air will be consumed.
Therefore, we need to transport air up from the earth, and then slowly replenish the oxygen in the entire scientific research station to ensure the air quality in the scientific research station.
Producing oxygen on the moon requires a lot of water, and currently our water resources are relatively limited, so we can only transport it from the earth first.
When water resources are abundant in the future and electrolytic oxygen is sufficient, there is no need to supplement. "
"It feels so complicated, it sounds a little dizzy." Zhang Jun rubbed the solar system's headache and said.
Hehehe, upon hearing Zhang Jun's complaint, Wu Hao and the others couldn't help laughing softly.
This is a very complicated super project, otherwise you think anyone would dare to set foot in it? Wu Hao joked with a smile, and then said to Zhou Xiangming: "Although the cost of our lunar cargo spacecraft is still relatively cheap~www.readwn.com~, seven lunar cargo spacecraft, plus the launch cost, are not worth it. a small number.
Therefore, on the one hand, we must cherish resources, ensure that they are used to the fullest, and do not waste them. On the other hand, it is necessary to speed up the development of the Moon Express. "
Speaking of this, Wu Hao looked at Yu Chengwu and asked, "How is the project going?"
Seeing his immediate boss asking about this, Yu Chengwu immediately sat up straight and reported to Wu Haohui: "Currently the project is progressing relatively smoothly, the preliminary plan and technical demonstration have been passed, and the research and development of the spaceship has been transferred.
At present, the development of the Moon Express is progressing relatively quickly, and the overall structure has been basically completed. "
As he said that, Zhou Xiangming slid the transparent folding tablet in his hand, and several photos of the Lunar Express under development appeared on the big screen, and the outline of the entire Lunar Express earth-moon transfer spacecraft could basically be seen inside.
The entire Lunar Express Earth-Moon transfer spacecraft is divided into three parts, namely the resource power module at the tail, the crew module in the middle, and the node module at the top.
From the perspective of this structure, it is actually a bit similar to the basic structure of our space station, which can be regarded as a small space station.
However, there are also big differences in some parts.
For example, the three on the space station are actually connected together, and they have a common name, which is the core module. On the Lunar Express Earth-Moon transfer spacecraft, it is divided into three independent parts.
From this point of view, its structure is more like a manned spacecraft, because the traditional manned spacecraft also has three parts, namely the resource power module, the manned return module, and the orbital module. A major function of the orbital module is actually to dock with other spacecraft.
