Military Technology

Just as Wu Hao and the others were talking, the live TV screen had switched to the first-person view of the extravehicular surveillance camera on the space station and the Walker 3 unmanned cargo experimental spacecraft.

At this time, the space station and the Walker 3 unmanned cargo experimental spacecraft were very close, about a hundred meters away, so they could already see each other on each other's screens.

At this time, we have entered the final, most difficult, and most critical moment of the space agency's rendezvous and docking. How difficult is it? In the words of aerospace experts, it is to penetrate a pinhole hundreds of meters away with the speed of a bullet.

This compatibility is actually not an exaggeration. The orbiting speed of our national space station is 7.68 kilometers per second, which means that it has to fly seven or eight kilometers in one second. At such a fast speed, it is necessary to realize the Walker 3 unmanned cargo experimental spacecraft. The difficulty of handing over and docking with the space station can be imagined.

Although the Walker 3 unmanned cargo experimental spacecraft and the space station are both at relative speeds, this high-speed educational docking itself represents the world's top aerospace technology, which only a few countries have mastered.

Although our space station has experienced dozens of dockings since it was in orbit, this kind of docking task has become routine and everyone does not pay too much attention to it.

But this is the docking experiment of our country's first commercial manned spacecraft. This is also the first time that the space station has docked a commercial manned spacecraft. Although it is unmanned, it is also a major initiative.

Especially if there are astronauts staying in the space station itself, docking in this case will undoubtedly pose a huge safety risk. If you are not careful, the consequences are unimaginable. I am afraid that this responsibility is something Wu Hao and others cannot bear.

So for Wu Hao, although he was very confident in their own technology, at the final moment of docking, he became inexplicably nervous and stared at the big screen for fear of missing any details.

Of course, it was useless for Wu Hao and the others to be nervous, because this docking was in automatic docking mode and did not require manual control. This is a common method for docking spacecraft in orbit. In addition, there is manual docking. However, this method is not commonly used and is only used in emergencies or training.

Although the main process is left to the space station and the Walker 3 unmanned cargo experimental spacecraft for automatic docking without human intervention, the astronauts on the space station will also pay close attention to the entire docking process and can stop the docking in an emergency. . It can even control the space station to perform emergency orbit changes to urgently avoid spacecraft and other spacecraft approaching out of control due to docking failure.

This time, the Walker 3 unmanned cargo experimental spacecraft is docked with the docking port located at the top of the space station's node module. As for the manned spacecraft originally docked here, it has been transferred to the docking port below by the robotic arm.

This requires that the Walker 3 unmanned cargo experimental spacecraft must first fly to a common orbit in front of the space station and maintain the same relative speed as the space station. Then it reversed direction 180 degrees, and then slowly decelerated, bringing the space station and the Walker 3 unmanned cargo experimental spacecraft closer and closer.

During this docking process, several parking points will be set up and approached step by step. Although it is a quick docking, the process is not fast. Because the closer we get to the final critical moment, the slower we have to go.

Eighty meters, fifty meters, thirty meters...

Ten meters, five meters, one meter! In the end, the spacecraft was parked in an area only one meter away from the space station. With everyone's attention, the space station slowly approached and finally docked together accurately.

good!

Lin Wei, who was next to Wu Hao, suddenly jumped up.

Wu Hao was startled, and then smiled.

Seeing Wu Hao's calm look, Lin Wei was a little puzzled and said: "Why are you so calm about such a big happy event? Please be happy."

Wu Hao smiled and then said calmly: "I must be happy, but just be happy in my heart. Let me jump up like you. I can't do this."

Tch, just pretend. Lin Wei rolled her eyes at him, and then a smile appeared on her lips. Then she picked up her mobile communication device and started to take a picture of Wu Hao, then walked over and started playing with it with a smile.

Wu Hao smiled and stood up, stretched, and then looked at the mobile communication device placed on the table next to him. Various messages began to pop up on it.

In response, Wu Hao couldn't help but smile bitterly and shook his head repeatedly. Although he didn't like this kind of social interaction, he still had to deal with it. No matter what the other party's mentality is, when someone calls to congratulate him, he can't refuse.

Although Coco will automatically reply to most messages for him, there are some calls and messages that he still has to answer in person. It seemed like it had become the norm for him to respond to these calls all morning.

Wu Hao is now a little scared, but he has no choice. Who wants to live in such a humane society?

After finishing these tasks, Wu Hao looked at the time and found that it was already noon.

Lin Wei was already busy in the kitchen. Wu Hao saw this and walked in. He saw Lin Wei wearing an apron and a headscarf, cooking vegetables.

Seeing Wu Hao come in, Lin Wei immediately pinched a piece of shredded meat with her hands, fed it to Wu Hao and said with a smile: "You are hungry, the food will be ready soon."

Wu Hao smiled and shredded the meat with his mouth, chewed it, then opened his mouth and fanned it with his hands.

so spicy!

This is Lin Wei's specialty dish, shredded pork with sharp pepper, which is actually stir-fried with two wattle sticks and green pepper. For those who are used to eating spicy food, the spiciness is not a problem, and they may even find it unspicy.

But for people like Wu Hao and Lin Wei, who can tolerate spicy food and like spicy food but are not very intolerant of spicy food, this level of spiciness is just right.

Hurry up and drink some water. I put too many vitex trees today. I'm looking for Shuyuan www.zhaoshuyuan.com. It's a bit spicy! Lin Wei couldn't help but urged when she saw the sweat on Wu Hao's forehead.

It’s okay, it’s okay, the spiciness is appetizing! Wu Hao said with a smile.

Lin Wei didn't insist when she saw this, but said while busy: "I fried shredded pork with pepper, beef with potatoes, steamed anchovies, broccoli with garlic, and tomatoes and eggs. and mushrooms and green vegetables, and finally made a stewed beef bone soup with Bawang flowers.”

That’s enough, they are all my favorite dishes! Wu Hao smiled and praised.

Okay, bring it to the table, it will be ready in no time! Lin Wei looked at Wu Hao's eagerness to try, and then said with a smile.

So cool! After receiving the instructions, we excitedly put the prepared meals on the table, then picked a bottle of red wine, took it out, opened it and introduced it into the decanter.

Lin Wei walked out of the kitchen carrying the last dish, looked at Wu Hao who was sobering up, and then laughed: "It seems that someone is in a high mood today, and he insists on being calm."

Haha, I’m happy today, let’s drink some! When Wu Hao heard this, he did not refute, but picked up the decanter and started to drink!
