Movie black technology

Although the video released by NASA can only see the full picture of the Tibetan antelope when it is zoomed in to the maximum multiple, but the public has no thought of disgusting it at all. They just envy and hate the Tibetan antelope in the video.

"Look at its graceful figure when it spins, like an elegant swan dancing on the lake!"

"Why is it the result of that genius again? Is there no one in the global scientific community? It took him less than a year to develop this unimaginable engine. Why did humans do it in the past few decades? Chemical rockets to death?"

"Although I have to admit, we probably took the wrong path in the past few decades. Liquid rockets and solid rockets are all wrong paths. Only electric propulsion is the real master of space in the future..."

"Look at other people's electric push spacecraft, and then look at our latest space command. Are you joking with the world? Although the rocket is thicker, longer and bigger, but want to use this thing to beat the electric push? Illusion fighters commute to and from work, right? Pure fantasy!"

"From the moment Chen came into my field of vision, I knew that this young man would definitely be able to support the future of mankind. He first developed AI and medical care, and now he has set his sights on space, the future treasure..."

On the space station.

The astronauts didn't know that the video captured by the space station just now had been released and caused an uproar. They were still discussing the Tibetan Antelope they had just seen.

But soon they have to move on to the next task.

That's radio talking to the ground.

It's just that this call is not with the ground station, but with the students on the ground.

This is a science and technology education project of NASA called "International Space Station Amateur Radio Communication Program". Young students from all over the world can have English questions and answers with astronauts on the space station as long as they apply for an appointment.

This is a very clever plan.

One can stimulate young people's interest in learning space exploration technology.

Second, this is also an excellent invisible talent attraction plan.

Educational organizations that can communicate with the space station through this plan are generally good schools and good students in big cities in various countries, or they are rich and backed.

The space dialogue between the two sides through the atmosphere, coupled with the designated dialogue language and the background of the space station, can not only arouse students' interest, but also establish a strong impression of Western technology in the students' minds, which will strongly attract them. In the future, as long as there is Opportunities, the chances of these students studying abroad will increase greatly.

Those who are attracted in this way are either high-end talents or rich and powerful.

Academic, economic and political win-win.

This plan has been carried out many times, and the astronauts are also very familiar with the process, and they quickly established a radio communication with the ground.

"Na1ss, Na1ss..."

A call to the International Space Station ham radio station came from the stereo.

Taylor was the first to respond.

"This is the International Space Station..."

After simply confirming their identities, the two sides quickly entered the question-and-answer session. Since the space station continues to operate in space, and radio waves are easily blocked and absorbed, this kind of radio call usually takes ten minutes. There are two or three minutes or tens of seconds.

The first few questions are common questions, nothing more than asking astronauts about life and feeling in space, and some space phenomena.

But Taylor soon heard a small commotion on the ground, and then the voices of the inquiring students suddenly became agitated.

"I just saw a video, did you meet the Tibetan Antelope in space?"

"Yes." Taylor and the others don't know about NASA's release of the video, but there is no need to hide this kind of thing. Any student in the second grade of elementary school can infer that they have a car. observe.

"Then, have you seen the transformation of the spaceship? I heard people say that the Tibetan antelope can transform into a mecha, and the Great God has hidden the mecha into a spaceship!"

The child's English is not very accurate, only the two nicknames "Great God" from abroad are very clear.

Taylor in space couldn't help being stunned, and it took a few seconds to realize what the ground was saying.

There is no child in this age group who is not interested in mechs. Compared with astronauts like them, the genius on the ground has much greater influence.

It wasn't really a space question at all, but Taylor couldn't possibly refuse to answer.

Because even she couldn't forget the sight she just saw, Taylor relished: "NO, I didn't see it transforming into a mech, it looked very shocking, it flew from the dark space, With the dazzling blue light, it's like opening a new era for us..."

Taylor wanted to continue talking, but the signal had gradually weakened, and the call was not over until the other party's voice could not be heard clearly.

Flight Control Hall.

The real-time situation of the spacecraft on the big screen changed, which immediately attracted everyone's attention.

"The spaceship has begun to slow down."

"Begin descent procedure..."

Chen Shen also looked up, the speed of the spaceship displayed on the screen had begun to decrease, and at the same time the spaceship was still maneuvering, as if it was about to turn around.

The staff in the hall also stepped up their vigilance again, always paying attention to the readings on their computers.

Chen Shen was not surprised, this was expected by everyone.

Because the time now has come to start the descent procedure of the Tibetan Antelope.

The speed of the spacecraft is now more than 8 kilometers per second, and the speed is more than 30,000 kilometers per hour. If it re-enters the atmosphere at this speed, the heat insulation layer outside the spacecraft will rub against the atmosphere violently, resulting in unbearable high temperatures.

After all, from the beginning of the design, the Tibetan Antelope did not consider entering the atmosphere at super high speed, so its insulation layer standard is not as good as that of ordinary spacecraft in some indicators, and it cannot withstand the high temperature generated by friction at all.

If you want to land safely, you must first decelerate in space to the acceptable range of the heat insulation layer before entering the atmosphere, and use the atmosphere and its own aerodynamic shape that is not conducive to gliding to decelerate further.

It can be seen on the screen that the Tibetan Antelope turned its head directly, and the plasma thrusters started at full power in the opposite direction of inertia.

The long wake reappeared in space, leaving traces even longer than the length of the spaceship itself.

This is the only way to slow down.

It is very simple to accelerate in space, even if you keep blowing air, you can slowly accelerate several tons of things, but it is not so easy to slow down.

A thing of dozens of tons flies with huge inertia, and it requires far more effort than when it was accelerated before.

Even if the plasma propulsion has been activated at full power, the speed cannot be reduced in a short while.
