"No. 3 Lunar Rover, suddenly lost signal!"

Hearing this news, Xu You was also taken aback.

Because the main task of the No. 3 lunar rover is to explore the back of the moon.

Although there are many uncertainties on the back of the moon, since landing on the moon, the performance of the No. 3 lunar rover has been very good, and there have been no accidents due to the implementation of the mission to explore the back of the moon.

Xu You quickly recovered his emotions, and asked calmly:

"Is it the cause of the No. 3 lunar rover itself, or the cause of the relay satellite?"

Here, the communication technology of the back of the moon is involved.

Because the back of the moon is always facing away from the earth, normally speaking, electromagnetic waves cannot pass through the moon to communicate with the earth.

The way we use is the signal relay satellite.

By launching artificial satellites near the moon, it can realize the role of a relay station to achieve the purpose of information transmission.

In this way, no matter where our lunar rover is, barrier-free information transmission can be achieved.

"Professor Xu, there is no problem with our relay satellite. It seems that the Lunar Rover No. 3 itself encountered some problem."

Xu You turned his eyes, and immediately thought of the most likely reason.

Electromagnetic radiation interference.

Since the back of the moon is not shielded by the earth, the intensity of electromagnetic radiation is about 300 times that of the earth's surface.

Under the strong electromagnetic interference, the short interruption of the signal is not unexpected.

"Keep an eye on Lunar Rover No. 3 at all times, and let me know immediately if you receive a signal."

"Okay, Professor Xu."

Since the signal from the No. 3 Lunar Rover cannot be received, any artificial control of the No. 3 Lunar Rover is impossible.

At this time, we can only wait for the recovery of the signal.

To everyone's surprise, one day later, the No. 3 lunar rover still did not recover the signal.

This news made everyone worry about the No. 3 lunar rover.

Xu You realized that the problem was more serious than he imagined, so he quickly found the information before the No. 3 lunar rover lost contact, and started researching it.

"Um?"

After carefully examining the various data, Xu You found out.

Before the No. 3 lunar rover lost its signal, within a very short period of time, the No. 3 lunar rover detected a sharp change in the intensity of electromagnetic radiation around it.

"Sure enough, it's the problem of electromagnetic radiation!"

This is a problem that Xu You can't handle at present. In areas where the intensity of electromagnetic radiation is too high, it is difficult to complete long-distance signal transmission.

And these too strong electromagnetic radiation will also have varying degrees of impact on various tests of the Golden Rabbit-1, and even make the Golden Rabbit-1 lose its direction judgment.

"In this area, what kind of special substance exists?"

Thinking of those mysterious reports from the Sam space agency, Xu You felt more and more chills down his spine.

Perhaps, the secrets that exist on the moon are far more complicated than Xu You estimated.

At this moment, Xu You had already thought of the worst.

That is, the No. 3 Lunar Rover will lose contact forever, and will never receive a signal from the No. 3 Lunar Rover again.

Losing a rover is a very big loss for us.

However, in comparison, this is much easier to bear than the dangers suffered by human astronauts.

The lunar rover can be rebuilt without it, but the astronaut has only one life.

Xu You couldn't help feeling thankful that the astronauts were not easily sent to the back of the moon to perform any tasks.

If the astronauts lost contact on the moon, everyone's worry level would be completely different.

Seeing Xu You's silence, Lin Shi persuaded:

"Teacher, in fact, things might not be that bad. Maybe the No. 3 lunar rover just went to an area with no signal, and didn't encounter any danger. Maybe it will resume signal transmission at some point."

"Well, I hope so."

Up to now, Xu You didn't dare to turn the other rover's directions, and went to the area where rover No. 3 lost contact.

Before the specific situation is known, if another lunar rover loses contact, the impact on the exploration of the moon will be too great.

…………

A few days later, the No. 3 lunar rover still has not recovered the connection of the signal.

As for the reason why the No. 3 lunar rover lost its signal, there are two main guesses.

The first is that the No. 3 lunar rover drove to an area with very serious electromagnetic interference, and the scope of this area is not small.

This situation is relatively better, because even so, the No. 3 lunar rover will still perform its tasks as usual, and most of the basic functions will not be greatly affected.

The second situation is that the signal system of the No. 3 lunar rover has been damaged, and there are even some more serious failures.

If this is the case, the No. 3 lunar rover will no longer be able to continue its lunar exploration mission.

Fortunately, we have launched a total of four lunar rovers this time. Even if one of the lunar rovers has an accident, the lunar exploration mission can still continue.

At this time, the Sam Space Agency contacted Xu You again, urging Xu You to deliver the rocket accessories.

This time, Xu You didn't delay any more.

"Commander Johnson, we have already tested the accessories to ensure that they can help the space launch system solve the problem of liquid hydrogen fuel leakage. I wonder if you want us to mail them there for you, or do you send someone to pick them up?"

Johnson thought for a while and replied:

"I'd better trouble Professor Xu You to arrange for it to be sent by mail. It is best to do it as quickly as possible and to protect the accessories with the strictest protection. We, the Sam Space Administration, will pay for all the costs involved."

"Of course, the cost must be settled by you." Xu You laughed.

Xu You didn't pursue the cost of accessories.

If the Sam Space Agency is not even willing to pay for the postage, then Xu You will not help the Sam Space Agency pay the bill.

"Professor Xu You, our Sam Space Agency will also pay another fee to thank Professor Xu You for his help."

"There is no need for this. If you want to, just send the fee to our National Space Administration."

Xu You didn't want to collect this fee in his own name. If people knew about it, it wouldn't be easy to explain.

"Okay, Professor Xu You, the arrangement will be as you said."

At this time, Xu You suddenly added:

"By the way, Commander Johnson. In order to better understand the performance of the space launch system after replacing the parts, I hope to get the synchronization data of this launch to help you solve some possible follow-up problems. Let the space launch system can be better optimized.”

Hearing Xu You's words, Johnson hesitated.
