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

Taking the first step is just the beginning of extravehicular activities.

In the ground command center, Lin Ju held the detailed list of this landing mission in his hand.

The next project is the most important flag planting. The two astronauts need to take down two folding electric flagpoles and raise two flags.

Unlike the Apollo project, which was just a "look", the Dawn project really planned to build a regular manned lunar base. Just planting a small flag would be too insignificant.

The cross-section of the folding flagpole carried by Shuguang-3 is an "L" shape with a groove. It is composed of 12 1.8-meter sections. It can be installed into two 10.8-meter flagpoles and then fixed with thin steel wire ropes and ground nails. Pretty solid on the windswept moon.

This job takes about 30 to 40 minutes to complete, and the two astronauts are now moving down the higher-definition television broadcast equipment to send back pictures with better angles.

A large part of the reason why the Apollo program in the 1970s was accused of falsifying the moon landing was due to the extremely poor video quality at that time. The technology at that time still used film transcription. It was passable at the time, but it seems very bad now. .

Needless to say, the quality of Shuguang-3’s live broadcast signal is high. There are many high-power satellites and space stations that can transmit it, and the bit rate and resolution are very high. At least no one can accuse the authenticity of the picture quality.

Now, the progress of the Dawn 3 mission has reached 99.8%, and it’s time to take a look at the Artemis 2 team.

Lin Ju approached Yun Hongjun. As the commander-in-chief of Changshi, he was very concerned about Artemis 2 and was currently watching NACA's YouTube broadcast on his tablet.

"How far have we come?"

Yun Hongjun turned the tablet over at an angle: "It's about halfway down. We should be able to land in 50 to 60 minutes."

"Blue Origin's technical skills are pretty good. The gadgets that were created in such a hurry actually still work."

Hearing Lin Ju's teasing, Yun Hongjun shook his head with a smile and said:

"You young people are always prone to think of others too simply. They have accumulated one or two hundred years of experience, and if they really start to attack, they will be very powerful."

After chatting for a while, Lin Ju sat next to Yun Hongjun, looking at the busy astronauts and looking at his tablet.

When Zhang Zhiguang puts up the flagpole, Artemis 2 will also land, right?

A black man and a woman, this is absolutely correct. Look at the altitude... there are still 14.4 kilometers...

Lin Ju suddenly frowned, tilted his head and glanced at the UI below the YouTube live broadcast again. What was now displayed below was "Hight: 14,600 m", 14.6 kilometers? Why is it still getting taller?

"Mr. Yun, take a look."

Yun Hongjun, who was still paying attention to the bouncing Fang Lin, lowered his head and didn't notice anything wrong for a while. It was only when Lin Ju pointed at the height that he realized what was going on.

Is this... the terrestrial TV station that added UI made a mistake? The height is rising?

The current descent rate cannot use the moon as a reference to judge whether the lander is ascending or descending, so Yun Hongjun first suspected that there was something wrong with the live broadcast team.

The two decided to watch it first, and after waiting for about a minute, the altitude reached 22.4 kilometers, paused for about two seconds, and then began to decline again.

But Yun Hongjun keenly discovered that the rate of decline was increasing.

Just a simple judgment, you can find that the acceleration of descent is about 1.5 to 2m/s^2, and the gravitational acceleration of the moon is 1.62m/s^2.

Before he could fully confirm this discovery, the live broadcast on the tablet suddenly changed to two male and female hosts. They chatted a few words with calm expressions, and then the screen changed to a real-time image of the outside of the "Portal" space station.

"Did you see that?"

Lin Ju nodded solemnly. It took almost 5 seconds from the altitude to stop at 22.4 kilometers and then to cut off the screen. He still remembered the last altitude he saw. He calculated it with a mobile calculator and found that the acceleration was almost 1.7m/s^2.

There is only one possibility for this situation: the lander's engine is not working, and it is descending rapidly under the influence of the moon's gravity.

At an altitude of about 20,000 meters, it will only take about 160 seconds if it does not slow down, and it will hit the moon in about two and a half minutes.

I'm afraid it's not a problem with the live broadcast, but that "Blue Moon" is in big trouble!

Yun Hongjun and Lin Ju hurried to find Academician She. Something big had happened!

"Losing motivation?"

The boss who was still in a meeting in Huayin was accompanying his superiors to wait for the Diyue connection to be held later. Suddenly he received a call from Qiongzhou saying that "Blue Moon" had lost power during the live broadcast and the current situation was unknown.

On the other end of the phone, Yun Hongjun, who had witnessed the whole process, was reporting:

"...I think the height increase that Kobayashi saw at that time should be real. There should be some malfunction. The two astronauts wanted to give up the moon landing, so the engine accelerated and tried to enter orbit again, but this effort ultimately failed due to loss of power. ;

Then, before the screen was cut off, the lander was falling at the speed of free fall on the moon. If there were no more attempts to escape, the aircraft would definitely crash and everyone would die! "

"Hiss—" The big man took a breath of cool summer air, which made his gums sore.

If Artemis 2 crashes on the moon, I am afraid that the flag of Dawn 3 will have to be lowered by half as soon as it is raised, and the message to the people of the world will have to be changed to a eulogy.

Just when he had a headache, Academician She snatched the call from the other end:

"I have a way. If Artemis 2 really loses power completely, it will definitely crash within two to three minutes... It's almost there now. There is a seismic monitor on the Dawn 2 lander we launched before. , hitting it at such a fast speed, the instrument must have responded!

I'll have someone adjust the data right away! "

"Okay, I won't hang up the phone, I have to confirm their situation first!"

On the other end, Academician She immediately called the unmanned lunar probe control center in Beijing and requested that the data from the seismic monitor be updated immediately.

He looked at his watch and saw that five minutes had passed since "Blue Moon" began to fall. If it had really lost power completely, there would definitely be no bones left.

Falling from an altitude of 20,000 meters, even under the gravity of the moon, it can be accelerated to nearly 260 meters per second, which is almost 930 kilometers per hour. It is equivalent to a jetliner flying at a high speed and hitting the lunar surface at such a speed. No matter what protective measures were taken, it was useless. It is estimated that even the remains of the astronauts were integrated with the lander.

The control center in Beijing was urged online by Academician She and gave the result two minutes later:

"Reporting to the commander-in-chief, we have obtained the latest data from 22 seconds ago. The seismic monitor found no abnormalities, no abnormal geological activities, no unconventional vibrations, and no other abnormal phenomena were recorded in the past 24 hours;

We also called up the vibration monitor on Yutu-3B and found no abnormalities. "

Academician She breathed a sigh of relief and immediately picked up another phone to report the situation to the boss.

"Does that mean the lander didn't crash?"

"It didn't happen within five minutes. It should have started successfully, but we don't know whether he will continue to log in or give up."

"Then let's keep the original plan and let others continue to follow up!"

"yes!"
