In the picture, Wanjie-1 began to slowly fly towards Mars.

Since the gravitational pull of Mars is smaller than that of Earth, you can see from the picture that the speed of the free fall of Wanjie-1 is relatively slow.

Of course, this slowness is also relative to the earth, and in fact, the speed is also very fast.

Because Wanjie No. 1 is loaded with an ultra-clear camera researched and produced by Wanjie Technology.

It can effectively prevent bright light and blurred images.

It can be said that it is difficult for them to see clearly in this picture, which means that the speed has reached the point where it is not clear to the naked eye.

In this way, everyone looked at this fast-moving picture, and their eyes couldn't help but be full of anticipation.

Once the picture stabilizes, it means that Wanjie No. 1 has landed.

What they want to see is whether Wanjie No. 1 can land smoothly, whether the equipment can operate normally after landing, whether the signal can be stably connected, and so on.

Because it has been falling from outer space, the speed is very fast, and the impact force formed is also very large, and it is very likely to damage Wanjie One.

Although the gravitational pull of Mars is much smaller than that of Earth, it is not careless at all.

Not only the spectators and experts, but even the staff of the Qiongdao launch center have this concern.

Looking at the people with melancholy faces, Lu Yuan couldn't help but smile slightly, his eyes were full of calm and indifference.

He has full confidence in Wanjie 1, and has tried countless times in the true simulation system, without a single failure.

This has proven that Wanjie 1 is perfect, and as long as it lands normally, there will be absolutely no problems.

Basically, the landing of Wanjie No. 1 has attracted the attention of people all over the world, not only the major domestic channels are broadcasting, but also many foreign influential media are also broadcasting.

After all, it is the first probe in human history to arrive on Mars in only half a month, which represents great significance and deserves everyone's attention.

After looking at the time, aerospace experts from some countries couldn't help muttering: "It should be almost time to turn on the buffer system." ”

The buffer system, as the name suggests, is a device that provides landing cushioning for these detectors.

If it lands directly at this speed, I am afraid that no matter how awesome the detector is, it will be smashed to pieces in an instant.

Therefore, there is a buffer system involved in these detectors, and when the detector is about to land, the bottom of the detector will release a recoil force downward, which will gradually cancel out the gravitational pull of the detector falling from the sky.

It's the same principle as rockets and jets.

The reason why the rocket can be lifted off is a jet propulsion device that uses the hot air generated by burning fuel to eject backwards at high speed and uses the generated reaction force to move forward.

In other words, as long as the combustion direction is pointed downward, an upward reaction force is formed, which prompts the rocket to lift off.

The principle of jet is similar, it uses the recoil effect of the gas produced during fuel combustion to be injected backward at high speed to make the aircraft fly forward.

The rocket is placed underneath and uses the reaction force to fly into the sky, while the airplane is placed on the tail and pushed forward by the reaction force.

In the same way, this device can also be installed under the detector, and only need to set the upward reaction force to be a little smaller than the force when landing.

Why a little smaller? It's because the probe is always going to land, and if the two forces are the same, it's suspended in the air.

Only a little more gravity than the reaction force will make a safe, slow, and stable landing.

Sure enough, when the detector descended to a certain altitude, the radar mounted on the detector had already detected the distance from the ground.

Therefore, the buffer system was automatically activated, and the huge energy energy carried by itself was used to generate a steady stream of upward reaction force.

At this time, you can clearly see that the picture paused obviously, and then you can see that the picture gradually slowed down.

And it's getting slower and slower, and everyone can't see the specific scene in the picture, but after this reaction force, the speed of the probe descent drops sharply, so everyone can also see some specific scenes.

But when they saw those scenes, their eyes were full of shock and amazement.

This is the first time they have seen the scene on Mars so intuitively, the new planet, the strange world makes them extremely curious.

As the altitude gets lower, the probe descends more slowly, and they see the scene more clearly.

It's just that the light at this time is not very good, so the picture is not too bright, and everyone does not see too much of the face of Mars.

It didn't take long for the picture to suddenly shake slightly and shake slightly.

Looking at this scene, the people in the entire command room were nervous, staring at the two lights in the command room.

One green light and one red light.

If everything is normal and there are no faults after Wanjie 1 lands, then after Wanjie 1 completes its self-inspection, it will pass back the information and light the green light.

If there are some minor problems, then the red light is lit.

If there is a big problem, it may be that Wanjie One will not be able to light these two lights at all, and even the picture will be lost.

So they were all nervous at the two lights at this time.

Although Lu Yuan was full of confidence, he was also quite looking forward to the two lights.

Suddenly, the green light came on!

"Good!"

Seeing that the green light was on, everyone in the command room was in good spirits, and then stood up and clapped their palms excitedly to celebrate the successful flight.

As soon as the green light is on, it means that Wanjie No. 1 has landed safely, and there is no error in all equipment and devices, and everything is perfect.

And this also means that this launch has been a complete success, and everyone's hearts have been hanging for half a month, and they have finally returned to their original position.

It can be said that everyone is very excited and happy.

Because this launch was so meaningful, the world's first probe to fly from Earth to Mars in such a short time and land perfectly was produced in their hands!

"The landing is normal, all the equipment is normal, the signal is normal!"

Subsequently, the person in charge of the briefing read out the message.

Suddenly, the audience, experts, and heads of state who were watching the live broadcast all knew the news and the news of the perfect landing of Wanjie No. 1.

After hearing the news, the whole world was in a stir.

There may have been such and such possibilities before, the failure rate, but now Wanjie-1 has landed firmly on the ground of Mars, and all the equipment is normal.

Thinking that Wanjie No. 1 only took half a month, the world was full of shock.

However, just when everyone was shocked, they suddenly saw a change in the picture, which was originally one screen, but now it has become two screens!

Seeing this scene, the corners of Lu Yuan's mouth finally showed a faint smile, and a touch of tenderness flashed in his eyes.

The third watch! There is also a change! Ask for a recommendation ticket! Ask for a monthly pass!
