The genius remembers the address of this site in a second: []https://The fastest update! No ads!

As ten o’clock approached, the atmosphere in the command and control hall of Xinyuehu Aerospace became tense.

All the staff are staring at the big screen, waiting for the last moment. This last 14-minute journey will determine the success or failure of the entire project, and determine whether the investment of hundreds of millions of yuan is in vain.

Does this descent process not require your intervention? Zou Xiaodong, who was sitting next to Zhang Jun, asked.

Yu Chengwu, who was staring at the screen in the front row, leaned on the back of his chair, turned around and explained to Zou Xiaodong: “No need, the whole process is completed by the system itself.

Although we have set up a series of automatic programs before this, the entire lander only needs to follow the steps set by the program. However, considering some emergencies encountered during the entire descent and landing process, some emergency measures are required.

Therefore, we have added an artificial intelligence system, which can perform corresponding processing according to the real-time data changes during the descent and landing process, so as to control the lander to land on the lunar surface safely and smoothly. ”

Speaking of this, Yu Chengwu turned his head and glanced at the big screen, then turned around and continued to preach: “Actually, in addition to the autonomous landing mode, we also have a manual mode, but this is only a backup for emergency use plan.”

Everyone nodded after hearing the words, and everyone looked at the big screen again. On the big screen is the real-time picture taken by the external camera of the lander. In the picture, the entire lander is flying slightly on the surface of the moon at a very fast speed. Below are some large and small craters and craters. It looks like Very desolate.

And beyond the arc-shaped horizon is a pitch-black space. Under the promise of the strong light of the moon, the starry sky cannot be seen, only one side is black.

Of course, we can see our earth from a suitable angle, but the earth we see is the same size as the moon when we stand on the earth, but it is blue.

This external surveillance camera actually shoots black and white images. This is mainly because black and white images do not take up the loan, and more image information is stored, so basically the external surveillance cameras on each spacecraft and satellite have special The remote sensing lenses are basically black and white photos and video images, only a small part are color images.

The reason why some of the photos and videos we see are in color is the product of post-grading. Of course, there are some color videos and photos taken directly, such as the real-time images taken by the external camera of the space station, which are in color.

However, the external functional camera on this detector takes black and white images, which is enough for scientific researchers.

The reason why the video images on the big screen are now in color is that it has been processed by the artificial intelligence system, so it can restore images comparable to color videos and photos.

And these are the pictures and photos, and they are just for the look and feel. They don’t mean much to scientists. In half of the cases, they are more willing to pay attention to those black and white videos and photos.

Get ready for a power down, five, four, three, two, one, engine start.

The engine started, the speed of the lander began to slow down, and with the help of the moon’s gravity, the lander began to continue to fall downward. Under the control line of the attitude engine, the attitude of the lander changed from a horizontal state to a vertical state.

Of course, it is not completely vertical, but has a downward arc or oblique angle. The lander will gradually adjust its attitude during the process of continuous descent and deceleration, and then gradually land.

clap clap clap…

There was a burst of applause in the hall, and Lin Wei and the other guests who didn’t understand it immediately applauded after seeing this.

But the applause fell quickly, and these researchers continued to stare at the big screen. For them at this moment, it is the most tormented. Because they can’t do anything except staring at the real-time beating data and pictures on these big screens. This should be their most helpless time. All their hopes are placed on the lander and the intelligence on the lander. control system.

The time on the big screen is increasing second by second, the countdown to landing is decreasing second by second, and the height from the ground is also decreasing.

Through the demonstration screen, you can see very clearly how long the lander is from the ground at this moment.

During the landing process, the pictures sent back by the external camera on the lander also began to become stuck. Of course, the freeze time was only a minute or two, and after that, it became smooth again.

Through the external camera installed on the bottom of the lander, the surface of the moon that is getting closer and closer can be seen very clearly.

The “Wangshu-2” lunar surface inspection rover has not done nothing these days. It has opened up a huge landing field for the entire lander on the lunar surface, and it also uses the trajectory of the inspection rover and the robotic arm. A large landing mark was drawn in the middle of the landing field.

But at this moment, in the picture sent back by the external camera at the bottom of the lander, the planned big landing bid h is clearly visible. And the intelligent control system of the lander has also captured and recognized this landing mark, and began to adjust the descent angle of the lander according to this landing mark, so as to achieve precise landing.

Fourteen minutes seemed very short, but at this moment, it made everyone feel extremely long, as if every minute and every second was suffering, but they were both afraid and looking forward to the arrival of the final landing moment.

At this time, Yu Chengwu, who had been staring at the big screen, suddenly leaned back in his chair, turned around, smiled at the crowd and said, “When the lander descends to a height of about 100 meters from the lunar surface ~www.mtlnovel.com~ will There will be a short hover. This process lasts about two or three seconds. On the one hand, of course, it is for the need of deceleration, and on the other hand, it is the final identification of the landing site, so as to determine the final landing site.

In fact, not only our lander is like this, but other probe lunar landers are like this. It will draw a radar picture of the lunar terrain during the hovering process, and then automatically avoid those craters and rocks. Find a flat place to land.

Although our landing site was developed and explored by the Wangshu-2 lunar surface inspection vehicle, we still added this procedure to ensure that the lander can land safely. ”

The lander begins to hover.

When Yu Chengwu introduced it, the landing screen on the big screen suddenly stopped, and then, about two or three seconds later, the whole screen continued to change again.

I saw that the picture was getting closer and closer to the moon’s ground, and finally in the picture of a mock lake, the picture turned dark black.
