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 more than 1,400 kilometers from our Zhihai Lunar Surface Scientific Research Station to the core of the golden meteorite.

Based on the calculation based on the traveling speed of our previous Wangshu-1 patrol rover, it can probably travel thirty to forty kilometers in one hour. Excluding their daily charging time, they can travel for about twelve hours, which translates to about three hundred to four hundred kilometers.

It’s 1,400 kilometers and it will take us about four to five days to arrive. However, this is in an unloaded state. If it is fully loaded, the entire traveling speed may be greatly reduced. It can intelligently travel about half the distance every day, which is about two hundred kilometers. In this case, shipping back may take a week.

In addition, after we arrived, we had to take out the core of the meteorite and load it into the car. The whole process also took time. There are also some accidents and problems that may arise during our journey.

So if you add it all up, it will take about fourteen days, which can be completed within one lunar day. "

After hearing Zhou Xiangming's answer, Wu Hao and everyone present nodded. If it can be controlled to 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.

“You know that whether it is the Wangshu-7 exploration test vehicle, the low-function engineering robot, or the engineering transport vehicle they will launch next year, they are all driven by electricity.

Among them, the Wangshu-7 exploration experimental vehicle does not have its own solar panels and can be charged and powered independently when used. However, there were no solar panels underneath the low-function engineering robots in those two days, including the engineering transport vehicle they were about to launch.

Hearing Yu Chengwu's answer, everyone nodded in approval. It seems that we have indeed prepared that plan for a long time and have prepared all aspects.

In addition, this layer of protective material can also minimize the burning of the gold meteorite core in the small atmosphere, thus providing some protection for it. "

Yes, that is indeed a small problem, but there is no way to solve it. Yu Chengwu nodded and said: "Using flexible solar photovoltaic power generation sails will solve these problems.

However, the top of the descender is especially equipped with a docking port, which facilitates retreat and docking with the orbiting spacecraft in orbit. It must be placed under there. The docking port at the top is blocked. How can it be retracted and docked with the orbiter? "

The frame structure shown in the picture is not actually the golden meteorite core packed into a cube frame made of alloy materials. Inside the frame, alloy steel bars, steel cables and other materials are used to retrogradely fix the entire meteorite core, thereby confining it within the cube frame.

Although they have no built-in battery module, they still need to be recharged regularly. The capacity of their battery modules can support them to complete the entire mission cycle. How do they solve the charging problem of those two cars during the retreat? "

They said later that such a small meteorite core should be installed outside your landing descender. Wouldn't it be possible to transport it back to the Zhihai Lunar Surface Scientific Research Station and install it? "

That kind of flexible solar power generation material is very heavy and takes up space. It is not a scroll when folded, and it is not a small canvas when unfolded. Using it, you cannot realize the charging problem of the two cars during the retreat. "

Because it will directly change the center of gravity of the entire descender structure, causing the entire launch descent process to be successful.

So you plan to just transport the golden meteorite core back. Its scientific research value is even lower, and its economic value is also very considerable. Why bother?

Zhou Xiangming continued: "Next year you will launch an experimental spacecraft, focusing on testing the reliability of your lunar landing, lift-off and return technology. Originally, you only planned to collect the data collected by your subsequent Wangshu-1 patrol rover. The lunar soil samples received as well as some lunar rock and lunar soil samples from the far reaches of Zhihai Sea were transported back to Earth.

Seeing Hong Jie continue to ask, Zhou Xiangming replied with a smile: "Since we are pretending to be outside, we can just hit it inside. That will make it easier to transport."

But after thinking about it, since there are not so few lunar soil samples left, it is necessary to transport so few lunar rocks and lunar soil. It will be enough to transport it back for experiments. If it is transported less, it will be no different from the soil under the earth.

Speaking of that, Hong Jiecui changed the picture and said: "Before the package is completed, you will use some materials that have not been transported to the moon to build a frame inside the golden meteorite core, and use the frame to fix the golden meteorite core on the outside. .

There are few spaces and connecting mechanisms under the cube frame, which is convenient for transportation and fixation.

Therefore, you conducted research and public relations on how to transport the golden meteorite core back, and finally came up with such a transportation plan. "

In that case, you only need to carry the frame, not the entire star core, and that frame structure is not conducive to your entire transportation and relay transfer process. "

Therefore, you cannot obtain relatively primitive gold meteorite core data information, which is not very important for your study of the formation of that kind of large planetary core.

Seeing everyone's curious looks, Zhou Xiangming smiled and slid his transparent folding tablet, then pointed at the icons under the small screen and said to Wu Hao: "That's right, considering how many times it took to transport it back. The sub-relay transfer and the golden meteorite star core are issues that can be retrogradely divided, so you decided to put it outside the landing descender instead of inside.

Speaking of that, Zhou Xiangming continued to change pictures and said: "To be honest, how to fix such a small and heavy gold meteorite core under the descender is a difficult problem.

Hong Jie showed a satisfied smile, then waved to a few people and said, "Tell me how they transported such a small meteorite core back to the earth.

Originally, its best fixed position should be at the top of the descender. It only needs to be fixed for a long time to avoid the problem of center deviation, so that it can smoothly descend and dock with the orbiter below the track.

Using your relevant tools at the research station, you cannot use some space films and space composite materials to retrogradely wrap the entire star core. The purpose of that is to prevent it from being contaminated during space transportation, as well as to prevent it from being contaminated when returning to the small atmosphere, in the small atmosphere and at the landing site.
