"We have completed five orbit changes." as the chief engineer of the whole flight plan, Mr. Qi is very excited: "we have gone through raising the perigee, correcting the deviation of the orbital plane, raising the apogee, orbital roundness and combination correction. Now, we have reached the position five kilometers behind the Mir space station and are about to meet and dock."
On the large screen on the left, you can see the spiral curve of Shenzhou III. now it is gradually approaching the Mir space station and waiting for the final docking time.
"Now, ask Mir to adjust its posture."
Flying in space is very complex. It is not that simple jet propulsion will change the direction, because there is gravity. For example, when jet backward, the spacecraft will not only accelerate, but also make centrifugal motion and raise the orbit. Therefore, the overall control is more difficult.
Now, it is necessary to adjust the posture of Mir, turn the interface to your side, and turn to the back!
Our side is catching up from the back, so the interface is at the back, which is the easiest to connect. If it is at the front, it is equivalent to holding a relay race in space and passing the baton, but it is not so easy.
Now, on the screen, looking at the huge Mir adjusting its posture, it is quite spectacular. The two compartments in front of and behind slowly ejected airflow towards the side, only a small part of it, and the Mir began to rotate.
In space, everyone is a Hercules. Even with a little finger, it can push hundreds of tons of Mir, because it is completely weightless here.
The Mir turned very slowly. When it turned slowly, its huge posture appeared on the screen, and everyone held their breath. This is the artificial heavenly palace, which is the largest celestial body in space. China is also looking forward to having its own space station!
Now the Han state has also met this condition. The maximum carrying capacity of the Han state's Long March 5 rocket can reach 25 tons, so the weight of each segment can be 25 tons. This 100 ton celestial body can be launched and assembled four times.
Assembling in space is definitely a technical job. It needs many out of the cabin operations and carefully controlled attitude adjustment. Of course, it's best to have a mechanical arm!
Only the space shuttle has a manipulator. In space, the manipulator can quickly push the position of each component, making it easier to assemble.
In the attentive gaze of Qi Lao and others, the space station completed the attitude adjustment, and then ejected gas again to prevent it from continuing to rotate. Otherwise, the space station will rotate endlessly.
At this time, the rear pair of interfaces appears in the lens. The lens starts to zoom in and aim at the pair of interfaces, which is also to prepare for the final docking.
"You already have graphics processing technology?" ilyushenko was surprised again.
The docking mainly depends on microwave radar and laser radar. These radars can control the error to centimeter level, so as to complete the autonomous intersection and docking. However, there are other means that can be used outside these systems.
Like images!
When the video captures the image, we know the exact location of the target, just like the human eye can see it, then analyze the target in the brain, and finally complete the docking and threading, which is similar to this.
However, that is the contribution of the human brain. If it is a computer, it needs the computer to have the ability of graphic recognition. It can analyze the pictures in the lens, what is the interface, what is the starry sky, etc. now, neither Eagle country nor bear country can do this ability, but Han country has done it!
In this regard, the state of Han has been far ahead.
Graphics processing? Of course, we have mastered it. Han has long begun to study this technology. What PS is backward. We can directly beautify our face, turn fat people into thin people, round chin into sharp chin, and small eyes into big eyes. What else can we do?
When applied to the aerospace field to improve the accuracy of docking, it is naturally transplanted.
"Attention, the spaceship starts. The distance is 400 meters!"
The passwords began one by one.
According to the plan, before the formal rendezvous and docking, the spacecraft will slow down and adjust at four berths 5 kilometers, 400 meters, 120 meters and 30 meters away from the Mir space station.
Now, the spacecraft is approaching a little bit, from five kilometers to 400 meters, berthing slightly at a distance of 400 meters, adjusting its attitude, and then further reaching a distance of 120 meters.
At this point, the lens adjusts the focal length, first zooms in to the entire space station, then zooms back to the docking point, and then to the next docking point!
"Thirty meters away!" when they heard this command, everyone held their breath and looked at the picture in space.
I saw the front orbital module of Shenzhou spacecraft, stretched out the capture lock like a hand, slowly approached, approached, and finally successfully penetrated into the card board of Mir. The first step is completed!
No one spoke and even stopped breathing. When we looked at the picture, although we could only see part of it, we still felt thrilling.
The capture lock slowly retracts backward and slowly pulls the two closer, one meter by one meter. The distance to the interface has been close to one meter, half a meter! Then, with a slight impact, the butt ring corresponds exactly! Then, the 12 hooks in the butt ring are tightly connected with the lock.
The green light flashes.
"Successful docking, now adjust the air pressure on both sides!"
"The air pressure is normal!"
"Open pair interface!"
"Check the tightness!"
"Everything is normal!"
Yes, yes! Up to now, there has been applause in the whole command hall. Finally, the docking was successful, and all the procedures were correct. Shenzhou III and Mir in space have become a celestial body! As long as we master the extravehicular technology, Han can build the space station!
"Han's spacecraft has been docked. We can retreat. Let's go first..." as the commander, Ramon began to assign. He planned to let several astronauts in charge of maintenance go back first. They insisted until the end. However, is there any difference? The first one to go up is the spaceship to the Han country. After all, the Han country has not carried out successful manned spaceflight. What if there is a fault when landing?
"NASA's mission order is coming!" just then, the communications officer said.
Ramon looked at the display on the screen and ordered Ramon to take two people to the spaceship of Han state!
Ramon put on his spacesuit, put on his helmet, and then floated out of the airlock, first into the crystal cabin, then across the airlock, and from the core cabin into the Han spacecraft that had been docked on one side.
When he floated in, he was stunned. Is this too advanced?
