&' /rz 7 tmx U H0 Q _eK Uy ' v GO} H months and 5 days, Lin Feng finally ended the days of watching the sunrise 15 or 6 times a day, and returned to the ground to enjoy the life of a normal person.

Before falling to the ground, he replenished the water and various salts according to the prompts.

Ordinary astronauts can't stand at all after returning to the ground, and the weightlessness will put the joints in a state of no load, so once they return to the gravity environment, if they barely stand up, they will feel back pain, and it will take at least one to two weeks to recuperate.

Lin Feng's physical fitness is strong, and he completely adapts to it after a few minutes, but he is obviously a little uncomfortable when he walks, and he feels a little fluttering, because his height has obviously grown several centimeters.

Sima Lili could originally reach the height of Lin Feng's ears, but now she could only touch his chin position, and she naturally knew that this was because of long-term weightlessness.

But she still felt a little incredible: "You...... Did you really go to space this month?"

"And where do you think I've gone?"

"I thought it would take a few months," said Sima Lili, "after all, it's a big project." ”

Lin Feng smiled and didn't speak, but walked with her on the bluestone road covered with peach blossom petals in the ancient city of the Lin family.

Huaxia has entered winter, this year's winter seems to be particularly cold, the sun has been out for a long time, and the hoarfrost on the city wall has not yet melted.

Lin Feng seemed to have the feeling of returning to his childhood, when there would be a few snowfalls in winter, and a snowman with no visible shape would be piled up at the door of each house.

"It's been cold this year. ”

"According to the Bureau of Meteorology, the temperature this year has dropped by 1.2 degrees compared to the same period in the past, basically returning to the level of 25 years ago. "It's all your credit." ”

"What does it have to do with me?" Lin Feng asked deliberately.

"First of all, the improvement of the desert environment, the absorption of a lot of carbon dioxide, then the reduction of carbon dioxide emissions, and the trade-off. ”

"But I've heard people say that if all the world's deserts were greened, the earth would enter an ice age?"

"It's alarmist. ”

When the two came to the door, the mother was holding Xiao Lin Fei in the sun, this little guy hadn't seen him for a month, and he had obviously grown a lot. My mother always felt a little weird when she looked at Lin Feng, but after watching it for a long time, she couldn't tell what was different.

While teasing Xiao Lin Fei, Lin Feng listened to Sima Lili's report on the results of the past month.

The global positioning system independently developed by the laboratory has theoretically achieved all the functions of the celestial pole system, but Sima Lili found that microquantum technology is far more than just communication and planetary surface monitoring.

However, there is a lack of relevant research conditions, so it can only be temporarily abandoned.

"Let's put the positioning system in the sky first," Lin Feng said after hearing this, "As for the follow-up research, we will do it again." ”

"Okay, I'll contact the General Space Administration in the afternoon to prepare a launch plan. ”

Lin Feng smiled and shook his head: "I'm ready, you just need to be ready to prepare what you need, and we can go to space in a few days." ”

Sima Lili thought he was joking, how could such a thing as going to space be done without a launch vehicle?

It will take more than half a year for a launch to go from planning to implementation to liftoff at the earliest.

Lin Feng didn't explain too much to him, after lunch, the two went to the laboratory together, and Lin Feng saw the small satellites that had been prepared, densely arranged on the ground.

There are 7,000 small satellites in the Tianji system, 3,500 of which Lin Feng bought for research, and 33,000 of them independently developed by Sima Lili.

They will operate in a geosynchronous orbit at a distance of 35,786 kilometers from the ground, and conduct all-round monitoring and positioning of the entire earth, including space and near-Earth space.

It is no exaggeration to say that if this positioning system, named "Magic Eye", is working normally, the actions of an ant on the surface of the earth will not escape its surveillance.

Of course, the cost of the magic eye is also extremely high, the production cost alone is as high as 50 billion, if the traditional rocket is used to launch these small satellites into space orbit, the total cost will be at least more than 5 trillion, and the time will reach 20 years.

This is too much in line with Sima Lili's style of acting, and Lin Feng was very surprised, how did she build so many small satellites in such a short time.

He looked at Sima Lili's emaciated face with a little distress, knowing that she must have been working overtime day and night again this month.

"I don't believe you'll be able to build a space station in a month, but I'm ready if you succeed?"

This is the reason why Sima Lili is working overtime desperately, and Lin Feng is angry and funny when she hears it.

After a few days of rest, Sima Lili's preparations were in place, and the first batch of 300 small satellites were loaded on the Shenxiang.

After saying goodbye to Xiao Lin Fei, the two boarded the Shenxiang, and then gradually disappeared above the white clouds.

"Where are we going?" asked Sima Lili.

"Go to the space station. ”

"Just use this plane?" Sima Lili was shocked, she had been on the Shenxiang many times, but she never knew that it could fly into space.

"Fasten your seatbelts, we're going to speed up!"

With a dense shudder, Shenxiang successfully broke through the atmosphere and soon reached the orbital altitude of the space station.

Sima Lili looked at the earth in front of her through the glass window in disbelief: "My God, we really came to space!"

Lin Feng shrugged his shoulders: "I told you a long time ago, in fact, we can go to the moon for our honeymoon, but you choose to go to the bottom of the sea." ”

The space station orbits the Earth in an hour and a half, so it is not in this position at this time. Lin Feng didn't want to wait, so he flew towards it with the Shenxiang.

Ten minutes later, a huge disc-shaped space station appeared in the sight of the two.

"What's that?"

"It's our space station. Lin Feng said with a smile.

"But...... But ...... with me? It doesn't seem to be quite the same, at least it's a lot bigger. ”

Lin Feng parked the Shenxiang in the No. 1 hangar, personally put on a protective suit for Sima Lili, and then turned off the simulated gravity of the Shenxiang, and the two floated like feathers.

It was the first time that Sima Lili felt weightless, and although it was new, she was even more anxious to see what the space station was like.

Lin Feng took her out of the cockpit of the Shenxiang and came to the living area of Area 1, where 300 special operations soldiers were doing various trainings, and when they saw Lin Feng coming, Li Guangping immediately walked out of the team.

Last time I took them to visit, Lin Feng didn't go to the main control room of the space station, but after Sima Lili came this time, as the security director of the space station, Li Guangping would enter the main control room with her to confirm the permission.

The main control room is located in Area 0, which is the most heavily protected place in the entire space station, and needs to pass through 3 high-strength alloy doors, and then there is 3 automatic defense system certifications.

It is not a large space, but it gathers all the monitoring signals of the entire space station, and is aggregated and processed by independent defense systems, which can predict various dangers in time.

After introducing the functions of the main control room, Lin Feng asked Sima Lili to give the space station an official name.

"How about calling it the Advance Number? It means that we will be based once and for all, heading towards the depths of the universe. ”

The name of the space station was so simply decided, Lin Feng entered the name into the main control computer, and then set the highest level of control authority for Sima Lili and the second level of control authority for Li Guangping.

Sima Lili asked again: "What if someone comes to attack us? It's only 400 kilometers above the ground. ”

"That's why he's here. Lin Feng smiled and pointed at Li Guangping.

"Aren't you going to let a few of us fly into space to deal with the enemy's lasers or missiles?" Li Guangping's eyes widened.

"Then how could it be," Lin Feng opened an extinguished light curtain, which was the computer that controlled the space station's weapon system, "You don't have to worry about the defensive ability, if you don't believe it, you can find a place to try it with a high-speed particle gun and see if you can make a hole in the shell."

"As for the attack weapons, there are only 8 ion cannons prepared at the moment, I hope you like it.
