I ask you to build tractors, but you build rockets?

"What a cloudy ice."

The lunar rover stopped on a small hill, which was a location marked by the robot. Fang Lin peeled away a thin layer of lunar soil and dug out a piece of ice half the size of a human body.

It is not pure at all, there are quite a lot of impurities mixed in it so that it looks more like an opaque off-white color.

Fang Lin took out the geological hammer he carried with him, knocked off a corner a few times, and held it in his hand for a closer look: The sunlight is also very weak now, and it is about to enter a moonlit night here, and it is almost time to return.

Zhang Zhiguang took a shovel and shoveled hard a few times, and then buried a radio beacon.

According to the robot's rough mapping, there should be a lot of shallow ice here, which should be used in the future.

This is already the third beacon buried, which is almost enough for the Dawn Project.

"Dongyao Dongyao, you should be returning soon."

Ding Jihua's voice came over the radio. The latter had completed the survey and returned to the vicinity of the lander, and was ready to release control of 14. He still had some work to do before taking a break.

"Understood, we will return in three minutes."

Under the lander, 14 regained control of his body.

[Commander, I still have a lot of power left. I have applied for the right to use the Lu-2 lunar rover from you. I want to bring back some of the samples from Shuguang-2]

“Yeah, I just forgot to ask Old Ding to do it, remember to choose according to the list;

Pay attention to safety and go back quickly. "

[Confirm the order, thank you for your concern. 】

14 sat on the lunar rover with a handsome posture, stepped on the accelerator and jumped out. No one is more familiar with lunar surface driving than it.

Dawn 2 is only about 900 meters away from here, but the terrain is closer to the impact crater and higher, so you need to take a detour in the past.

The moon's electricity was still half full of energy, and it quickly climbed to the highest point of the terrain.

"...beep beep beep-beep-beep...beep beep..."

Radio channel 14 covers all communication bands, and it heard very sudden and regular radio waves.

The signal was very weak, and it could be heard that it was interrupted from time to time, but it might also be because the distance was too far, because he could only receive it when he was standing on a high point.

14 Stop the lunar rover and patiently listen to the information in the radio wave.

The radio wave is very simple. After almost ten seconds, it pieced together the content that the signal source wanted to send out from the intermittent information:

"Beep beep beep, beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep beep"

Three short, three long, three short, the standard Morse code format of the international distress signal S.O.S.

14 spent 0.01 seconds thinking, and then took the initiative to make his own voice on the radio:

[An unregistered radio signal was found. The transmitter is suspected to be sending an S.O.S rescue request. The encryption method is Morse code;

The direction is unknown and the signal source is unknown. It complies with the AAAAA implementation standards. The frequency band has been recorded and instructions are requested;

Repeat, discover...]

The robot's voice sounded to the astronauts and the ground command center one after another, startling everyone.

Immediately afterwards, the ground began to receive the data packets sent back by 14, as well as the shared current field of view. This was the response method written in its AI: sue the parents immediately.

Lin Ju, who had been waiting impatiently for Artemis 2 and was about to go back to sleep, suddenly became energetic and immediately issued instructions to the base to control 14 to obtain more information.

Zhang Zhiguang, who was returning to the lander with some samples, also had his eyes widened. He immediately asked 14 on the radio and learned that the signal was too weak to obtain effective information, and the signal seemed to be still fading.

"Command center, can you determine whether the signal comes from the ground or space?"

"Wait a moment, Dong Yao. You should return to the landing module immediately and wait for the next instructions. We have just received the data and are in the process of emergency confirmation."

"Brother Zhang, is it them?"

Fang Lin was a little excited. There was a probability that the radio distress signal recorded on 14th came from aliens or from the "Blue Moon", but it seemed that the latter was more likely.

Zhang Zhiguang knows that the ground must be still discussing it, but if the signal is sent back from the lunar surface, then they may have work to do!

After thinking rapidly in his mind for a while, he made a decision:

"Let's go back first, charge and rest the spacesuit and lunar rover, and be ready!

14? Go to the highest point around you immediately to get more information and report back in time! "

[Confirm the order, I will go to B04 highland. 】

…

Ground command center.

The control center on the 14th, like the Explorer and Yutu, has control rooms in Beijing and Xinyuan bases for remote monitoring, but now part of the data has been transferred to the launch command center in Qiongzhou.

Academician She is still sitting here and immediately organizes a judgment on the radio signals received by 14.

The first is the source of the emission: excluding aliens and unmanned lunar probes, then it can only come from spacecraft controlled by NACA.

The satellites, space stations, and spacecraft they launch into orbit are also excluded. The signals in the sky should not be interfered by the terrain near the landing site.

In the end, it is almost certain to be "Blue Moon".

After carefully comparing the received signal fluctuations, we can confirm with 70% confidence that the emission source is fixed.

"We are now 80% sure that the Blue Moon landed and it was them who sent a distress signal on the lunar surface."

Academician She's expression was unprecedentedly serious. This was definitely an extremely dangerous situation.

Lin Ju also nodded. He has been engaged in aerospace. He is now considered an expert. At least he understands the basic components and safety measures.

"There are at least two or three sets of communication facilities on the lander. Even if their spacesuits fail, they still have high-power communication devices. Trained astronauts can definitely use them to communicate with space, and all of them have guaranteed calls or network transmission.

This doesn’t count other portable communication devices, as well as television broadcast signal transmitters?

Being able to force astronauts to use the simplest Morse code to send a distress signal means that so many redundant measures have failed. It is simply unimaginable how astronauts can survive in such a situation.

Mr. She, I'm afraid we have to start searching with all our strength immediately. The two astronauts should be in a very dangerous situation now. "

…

"Please rest assured, we just had a small problem. They will be safe and sound soon, I promise."

In the Presidential Palace, the widows and family members of the four astronauts looked at John with tears in their eyes, and the latter's scalp went numb at the look.

Jeremy's mother is a black man who weighs over 200 pounds. Her waist is so thick that she can barely get in. She cried the most violently of all, turning the place into a pig-killing scene.

"...My dear little baby, he has been an obedient child since he was a child. I..."

The plump black aunt suddenly hugged John. The strong breath made John subconsciously hold his breath, and at the same time he tried his best to break away from the aunt.

In the end, four special agents rushed forward and exerted their strength, causing the aunt to reluctantly let go and wipe her tears.

"Mrs. Jenny, don't worry. We have just lost contact and have not confirmed it yet. NACA is doing our best and we will definitely bring your child back."
