Chapter 1,704 The cargo spacecraft mission is approved
Wu Hao's worries are unfounded. Even on earth, human beings' technical capabilities for construction in high-cold and permafrost layers still need to be improved. There are even many technical problems that have not been solved. What's more, this is on the moon, and the deep moon
It is still unclear what the conditions of the permafrost layer are, let alone how they can be utilized.
Of course, what Zhang Qutong said is correct. Just because it is not feasible at this stage does not mean that it will not work in the future. Besides, this is just a detection, and it is still far from the future application stage.
In the next twenty-four hours, the "Wangshu" intelligent lunar surface patrol rover began to sample, detect and analyze the lunar soil inside the entire crater and around the crater.
The results show that the oxygen content of the lunar soil inside the crater is much higher than that of the area near the crater. One of the findings of this detection is that they also detected oxygen costs in the lunar soil in the air sea basin outside the crater.
It's just relatively thin.
The results of nutrients are already very exciting. On the one hand, it verifies the previous research results in this area. The lunar soil does contain oxygen. On the other hand, it also provides a new direction for the future collection of oxygen in these lunar soils.
Found the direction.
In the future, the collection of oxygen in the lunar soil will definitely not be unilateral or the mining of a single element or a single mineral, but comprehensive mining.
You must know that these lunar soils not only contain oxygen, but also contain other mineral elements, such as ilmenite, copper, rare earth elements, and helium-3, which is abundant on the moon and coveted by humans.
It is worth mentioning that the refining method of helium-3 is actually similar to the refining method of oxygen. Helium-3 itself is also a gas and needs to be extracted by heating the lunar soil. Therefore, in the mining and extraction process of these minerals, these minerals will naturally be extracted.
resources, or to make full use of the resources in the lunar soil.
After completing the detection mission of this crater, the "Wangshu" intelligent lunar surface inspection vehicle continued its journey. According to the plan, this time it will move 80 kilometers to the Qihai crater.
Exploring a moon stream.
The so-called moon stream is by no means a real lunar stream, but describes a dark, elongated crack on the lunar surface that is similar to the terrain of streams on Earth. It is usually used to describe any long and narrow groove on the lunar surface that is similar to a riverbed.
These moon streams range from several kilometers wide to hundreds of kilometers long. Scientists divide them into three types based on their properties: meandering moon streams, bow-shaped moon streams, irregular moon streams, and straight moon streams.
The moon stream is of great significance for people on earth to study the development history of the moon, so this time the "Wangshu" intelligent lunar surface patrol rover will explore an irregular moon stream. This moon stream is about seven or eight meters long.
It is about 100 kilometers long and has irregular shapes. The Moon Creek is of different thicknesses and depths. According to detection, the Moon Creek may be hundreds of meters deep, and as shallow as one or twenty meters.
This time, Zhang Qutong and the others hope to understand the cause of the formation of this irregular moon stream through close-range detection, and thereby understand the previous geological activities of the moon. In addition, Zhang Qutong and the others also hope to learn from the bottom of the moon stream valley.
Find surface ice to find water.
The outside world is also paying great attention to this detection mission. You must know that this is the first time that Yuexi has been detected. So everyone is looking forward to something being discovered this time.
Wu Hao is naturally very concerned about such detection missions, but it is impossible for him to stay at the Xinyuehu Space Command and Control Center around the clock, or to say that he dare not only care about this one thing around the clock. This is obviously unrealistic.
He still has a lot of work to do, such as aerospace matters. Although the Haoyu Aerospace subsidiary is responsible for most of the time, when it comes to some major matters, Wu Hao still has to personally participate in the decision-making.
With the successful launch of their Jianmu-7 retractable medium-sized launch vehicle, they have also confirmed their leadership position in the field of commercial launch vehicles. In addition, this time the "Wangshu" intelligent lunar surface patrol detection
The vehicle successfully landed on the moon, which further demonstrates the strength of Haoyu Technology in the field of aerospace technology.
In particular, the outstanding performance of the "Wangshu" intelligent lunar surface inspection rover on the moon has also attracted attention from all aspects.
With so much attention, another piece of good news came. The project they had discussed with the aerospace authorities before about their third unmanned experimental spacecraft going to the space station for docking experiments was finally officially approved.
This time, their unmanned experimental spacecraft will take on the task of a cargo spacecraft, transporting some oxygen, food and water supplies to the space station. In addition, it will also transport some instruments and equipment to the space station, with a total cargo weight of four
tons, which is slightly lower than the Tianzhou cargo spacecraft. In addition, this time, their Walker unmanned experimental spacecraft will also transport some items back from the space station. Including two sets of extravehicular materials that astronauts will eliminate
Space suit.
The use of this kind of extravehicular space suit is limited in frequency and time. Use it once and less once. After reaching the limit of service life, it will generally be replaced and eliminated for safety reasons.
The discarded extravehicular spacesuits will be loaded into the cargo spacecraft and returned to the atmosphere with the cargo spacecraft to be burned.
This time, what their Walker unmanned experimental spacecraft will transport back from the space station are two sets of extravehicular space suits that are about to be eliminated and destroyed.
Why should they be brought back? The main reason is because the Walker unmanned experimental spacecraft they are about to launch has space on it and will return to Earth, so the scientific research experts are thinking about what they can bring back to Earth.
Because it is in the experimental stage, personnel must not be allowed to ride on it, so the only way to put supplies is there. It just so happens that there are two sets of extravehicular space suits here that are about to be phased out. Instead of loading them into cargo spacecraft and burning them in the atmosphere, we can
Why not take a ride and bring it back.
In this way, waste can be avoided. After all, these two sets of extravehicular space suits are valuable. Although they have reached the end of their service life, it would be a pity to burn them like this. It is better to bring them back and use them as national defense research and education exhibits.
This is better.
You know, several museums want to collect this kind of extravehicular space suit, but they don't have anything. What's more, this kind of extravehicular space suit that has actually been in space and has expired is even more precious and meaningful.
.
Secondly, these two sets of extravehicular space suits have been used on the space station more than ten times and have expired. If they can be transported back and studied, this will greatly promote the improvement and upgrading of extravehicular space suits in the future.
It was precisely based on these considerations that they stuffed these two sets of extravehicular space suits into their spacecraft and took a ride back to Earth.
