It is absolutely exciting for humans to travel through space in a normal state of gravity.

For safety, there was also a pilot in the cockpit, and with the help of the pilot, Li Cheng, who was in actual combat for the first time, slowly drove the spacecraft off the ground.

"Accelerate."

……

After a smooth flight, the spacecraft flew at top speed and broke through the atmosphere in less than ten minutes.

When he felt the spacecraft stunned, the experienced pilot immediately asked Li Cheng to turn off the fuel and change to electric propulsion.

"Set a coordinate, and then you're ready to drive autonomously."

"It's really easy." After setting up the autopilot, Li Cheng got up from his seat and said to Xu Ziling and Yang Kaiming.

The spacecraft is designed with an autopilot system that has more advantages than the fighter in terms of avionics system, and it is more comfortable to pilot, especially outside the atmosphere, due to the problem of obstacles, there is basically no problem of route selection, and compared with the aircraft in the atmosphere and still need to fly according to the prescribed route, this kind of navigation is undoubtedly more simple.

"Simple is simple, but you still need to pay attention to one thing in the process of driving, there is a lot of space junk in near space." From his design, Xu Ziling certainly understands this.

Space junk, also known as space debris or orbital debris, is a man-made object in space in addition to the working spacecraft, which includes the debris generated by launch vehicles and spacecraft during the launch process, scrapped satellites, the peeling off of spacecraft surface materials, and the paint plaques that fall off the aging of the surface coating; solid and liquid materials leaked from spacecraft; Debris from explosions and collisions of rockets and spacecraft.

These things are big and small, but don't look at these things scattered, but their lethality is definitely not to be underestimated.

You must know that these things are moving at a speed of 7-8 kilometers per second in an orbit of 300-400 kilometers, and at a geostationary orbit at an altitude of 36,000 kilometers, they are moving at a high speed of 3 kilometers per second, and the relative speed of collision can even reach more than 10 kilometers per second according to the inclination of the orbit.

With such a high-speed operation, you can imagine how strong its impact force is.

According to accurate calculations, a space junk with a diameter of 10 centimeters can completely destroy a manned spacecraft or satellite.

The hull of their spaceship is made of super strong alloys, but once they come across these things, although they will not destroy the ship, they will definitely be severely damaged, think about the result of the ship's damage in the space where the front and back of the village are not in the back......

Therefore, you still need to be extremely careful when piloting the spaceship.

These problems are the problems that must be paid attention to when piloting a spacecraft, so there is corresponding training when on the ground, and for serious consequences, Yang Kaiming and Li Chengshen think so.

"The system will avoid the space junk field!" Let the accompanying pilot take over the pilot, and Li Cheng sat in the back seat.

"Hmm." Xu Ziling nodded, "Connected to the Eagle Eye satellite, space junk within 100,000 kilometers will be detected under normal circumstances, but once it exceeds the range of satellite scanning, we can only use the spacecraft's own radar system, and we need to pay attention to it at that time." ”

The distance between the Moon and the Earth is 380,000 kilometers, and once a spacecraft lands on the Moon, beyond the distance detected by the Eagle Eye satellite, it must use its own radar system, which means that it is the most dangerous in the last leg of the journey.

However, space junk formed by debris such as spaceships and satellites will not appear in this area, and this distance is actually safe.

This time, the few people were just interested in test driving the spacecraft, and they were not ready to land on the moon, so they wandered around space for a while, took some photos, and then returned to Earth.

So far, the ship has been a real success.

Back on Earth, Xu Ziling told Fan Yi about it.

Fan Yi knew that Red Star was working on the spaceship for a while, but he didn't know the progress, someone told him a few days ago that Red Star had been turning on the shielding system for a while, and he guessed that the spacecraft might have been built, but he didn't expect that it had reached the point where it could land on the moon.

When he heard Xu Ziling say that the spacecraft could already land on the moon, he was taken aback.

"You've gotten this far?" At this time, the shock in his heart was incomprehensible.

It's a spaceship!

And it's a spaceship with a normal gravitational field in the cabin!

Not the so-called spacecraft of those space companies now!

"Are you sure that you can go to the moon with a man, and when you are in space, you will be the same as you are on Earth, and there will be no gravitational problems?" Even if Xu Ziling said it very clearly, he still couldn't help but ask again.

"No problem, we just walked around space." Xu Ziling told Fan Yi about the space trip just now, "According to our previous speed, it only takes more than ten hours from takeoff to landing on the moon. ”

"Ah......h

Fan Yi was surprised again.

Whether it is a manned spacecraft or a lunar probe will not walk a straight line distance when launched, but fly to the moon according to a large elliptical orbit, so the least time spent is hundreds of hours, and now I heard Xu Ziling say that the spacecraft only took off to land on the moon for more than ten hours, and the shock in his heart can be imagined.

"No wonder you've been turning on the shielding system for more than a month." It was a long time before he said that.

Xu Ziling was not surprised by this situation, and there was nothing he couldn't figure out in his heart.

He had long known that there was a monitoring of the Red Star from above, and it had never concealed this from above, which was an open secret.

"It's not that I'm worried that my own people will know, but to prevent other countries' reconnaissance satellites." Even though he knew that the above could understand their actions, he explained.

"It's okay, it's the right thing to do." Fan Yi calmed down his mood, "I will report this news immediately, you make preparations, it is estimated that someone will come to you soon, and some specific arrangements will be talked about later." ”

In some things, the company is neither more powerful than the government, and he didn't report the news of the spaceship to the top before, but he just thought that once the progress of the spaceship was known to the above, they would not be able to control it.

Now that the report has been given to the above, he naturally has such preparations.

What about this ship for the country now? The technology is in their hands, and they can build another one at any time, just a few months at most.

"No problem."

Xu Ziling still underestimated the country's attention to spacecraft, originally thought that it would take several hours to react at the earliest, but what he didn't expect was that less than two hours later, a military plane landed directly at their airport.

"This is still the first one?" After receiving the notice, he rushed to the airport as soon as possible, but what he didn't expect was that the person in charge of the airport tower told him that in the past two hours, he had received five notifications that he would land at the airport within an hour.

"How many people are going to be up there......"

[The book has entered the end and will be over soon.] Because of the contract with the website, work, family and many other reasons, this book has been delayed for several years to finish, once again to the many book friends who have been chasing this book to say sorry, the new book has signed a buyout contract, it will definitely not be like the old book so procrastinated, I hope to get everyone's support at that time! Thank! 】
