Two Thousand Nine Hundred and Thirty One Gold Meteorite Core Transport Plan (B)
After listening to Zhou Xiangming's explanation, Wu Hao did not comment, but asked him: "How long does the entire transportation process take?"
Seeing Wu Hao's inquiry, Zhou Xiangming immediately responded: "It is about 1,400 kilometers from our Zhihai Lunar Surface Scientific Research Station to the core of the golden meteorite.
Calculated based on the traveling speed of our previous Wangshu-1 patrol rover, it can travel approximately thirty to forty kilometers in one hour. Excluding their daily charging time, it can travel approximately twelve hours, converted
About three hundred to four hundred kilometers.
It will take us about four to five days to arrive at 1,400 kilometers. However, this is in an unloaded state. If it is fully loaded, the entire traveling speed may be greatly reduced. About half of the smart traveling is done every day.
The distance is about two hundred kilometers. In this case, it may take a week to transport it back.
In addition, after we arrive, we have to take out the meteorite core and load it into the car. The whole process also takes time. There are also some accidents and problems that may occur during our journey.
So if you add it all up, it will take about fourteen days, which can be completed within one lunar day."
Hearing Zhou Xiangming's answer, Wu Hao and everyone present nodded. If it can be completed within one lunar revolution, it will not take long and is completely acceptable.
"I have a question." Yang Fan asked Zhou Xiangming and others.
"We know that whether it is the Wangshu-2 exploration test vehicle, the multi-functional engineering robot, or the engineering transport vehicle you will launch next year, they are all driven by electricity.
Among them, the Wangshu-2 exploration experimental vehicle has its own solar panel, which can be charged and powered independently. However, these two days of multi-functional engineering robots do not have solar panels on them, including the engineering transport vehicle you are about to launch.
the same.
Although they have built-in battery modules, they still need to be charged regularly. The capacity of the battery modules cannot support them to complete the entire mission cycle. How do you solve the charging problem of these two vehicles while traveling?"
Yes, this is indeed a big problem, but it is not unsolvable. Zhou Xiangming nodded and said: "These problems can be solved by using flexible solar photovoltaic sails.
This flexible solar power generation material is very light and does not take up space. It turns into a scroll when folded and a large canvas when unfolded. We can use it to charge the two vehicles while they are traveling."
Hearing Zhou Xiangming's answer, everyone nodded in approval. It seems that they have indeed been preparing this plan for a long time and have prepared all aspects.
Wu Hao showed a satisfied smile, then waved to a few people and said, "Tell me next, how do you transport such a large meteorite core back to Earth.
You said before that such a large meteorite core cannot be installed in our landing ascender, so can it be installed if it is transported back to the Zhihai Lunar Surface Scientific Research Station?"
Seeing Wu Hao continue to ask, Yu Chengwu smiled and replied: "Since it can't be loaded inside, then just hit it outside. This will make it easier to transport."
Seeing everyone's curious looks, Yu Chengwu smiled and slid his transparent folding tablet, then pointed at the icons on the big screen and said to Wu Hao: "That's right, considering the several relays during the transportation back.
, and the problem that the golden meteorite star core cannot be divided, so we decided not to load it into the landing ascender, but to put it outside.
Using our relevant tools at the research station, we can use some space films and space composite materials to wrap the entire star core. The purpose of this is to prevent it from being contaminated during space transportation, and also to prevent it from returning to the atmosphere when it returns to the atmosphere.
The atmosphere and landing site are contaminated.
In this way, we can obtain relatively primitive gold meteorite core data information, which is very important for us to study the formation of this asteroid core.
In addition, this layer of protective material can also greatly reduce the burning of the gold meteorite core in the atmosphere, thus providing some protection."
At this point, Yu Chengwu changed the picture and said: "After the package is completed, we will use some materials that have been transported to the moon to build a frame outside the gold meteorite core, and use the frame to fix the gold meteorite core inside.
In this way, we only need to transport the frame to transport the entire star core, and this frame structure is also conducive to our entire transportation and relay transfer process."
This frame structure is shown in the picture. In fact, the golden meteorite core is put into a cube frame made of alloy materials. Inside the frame, alloy steel bars, steel cables and other materials are used to control the entire meteorite.
The star core is fixed to limit it within this cube frame.
There are many vacancies and connecting mechanisms on the cube frame, which are convenient for transportation and fixation.
Yu Chengwu continued: "Next year we will launch an experimental spacecraft to focus on testing the reliability of our lunar landing, lift-off and return technology. Originally we only planned to collect the data collected by our previous Wangshu-1 patrol rover.
The lunar soil samples received as well as some lunar rock and lunar soil samples near Zhihai were transported back to Earth.
But then I thought about it, since there are already so many lunar soil samples, there is no need to transport so many lunar rocks and lunar soil. It will be enough to transport it back for experiments. If you transport too much, it will be nothing like the soil on the earth.
There's a difference.
So we plan to just transport this golden meteorite core back. Its scientific research value is higher and its economic value is also very considerable. Why not do it.
Therefore, we conducted relevant research and public relations on how to transport this gold meteorite core back, and finally came up with such a transportation plan."
At this point, Yu Chengwu continued to change pictures and said: "To be honest, how to fix such a large and heavy gold meteorite core on the ascender is a difficult problem.
Because it will directly change the center of gravity of the entire ascender structure, causing the entire launch ascent process to fail.
Originally, its best fixing position should be at the top of the ascender. It only needs to be fixed for a long time to avoid the problem of center deviation, so as to smoothly ascend and dock with the orbiter on the orbit.
However, the top of the ascender is usually a docking port, which facilitates docking with the orbiting spacecraft in orbit. But if it is placed on top, wouldn't the top docking port be blocked? How can it be docked with the orbiter?
