Nine Hundred and Thirty-Three Landing
933 Landing
Everything is normal, Ye Han stretched and stood up: "Let's go, leave one person on duty, and the others can go back to take a shower and sleep."
"Is this over?" Luo Qi was a little confused.
He was called back by Ye Han temporarily, and he didn't have time to look at the engineering plan.
Ouyang Ping stretched out his hand and pulled him up: "Let's go, it will take several days, I will take the first shift first!"
Luo Qi's eyes fell on the screen, and suddenly he understood what Ouyang Ping meant.
The speed of the spacecraft traveling between the earth and Jupiter must not be slow, otherwise it will take too long to go.
The speed of ordinary spacecraft is quite fast, not to mention the fast transport ship, which is so fast that it can't get close to Jupiter. Jupiter's gravity can't catch such a fast spacecraft, it must have passed by, and no one knows where it flew.
Therefore, any spacecraft flying to Jupiter must slow down a few days in advance and reduce the speed to a point where Jupiter can catch it, so that it can smoothly enter the orbit and circle around Jupiter.
This is the law of nature. No matter whose spacecraft it is, it must be followed. The same applies to Kuaijiu and the cable.
Kuaijiu, which is towing the cable, is like a locomotive, but the cable is soft. Kuaijiu can slow down, but the cable will definitely continue to float forward.
There are only two ways to slow down the cable. One is for Kuaijiu to turn around and throw the cable to the front, and then the spacecraft slows down to hold the cable.
The second is to use the one just now, and then another spacecraft slows down synchronously.
Beidu has specially found several aerospace experts for this. Everyone agrees that the second method is more reliable, so today's incident happened.
Now the speed of the spacecraft and the cable is a bit fast, and it will take a few days to slow down.
After figuring out the joints, Luo Qi went back to sleep. The next day, he got up after a good sleep and asked for the engineering plan of the orbital elevator. He read it carefully from beginning to end, and finally had a rough idea in his mind.
In the next few days, the most important task of the forward base is to pay attention to the deceleration progress. The command room is always manned 24 hours a day for fear that there will be problems with the cable.
Fortunately, everything went smoothly. A few days later, the speeds of the two spacecraft and the cable dropped below the standard line at the same time, and at this time, they also flew near Jupiter.
The two spacecraft flew to the synchronous orbit and stopped, circling Jupiter while adjusting the direction of the cable. Specifically, the two spacecraft continued to keep their distance to keep the cable roughly straight, and then the Kuai San ship slowly approached the Tianhe.
The Tianhe was no longer in its original position, and moved to the synchronous orbit of Jupiter in advance. After the Kuai San ship approached, it directly spit out all the contents in the belly of the ship and handed them over to the Tianhe.
The Tianhe received the outer end of the cable, pulled the fixing device into the depths of the space station and fixed it firmly, and finally locked the fixing device. From then on, unless the fixing device was blown up, no matter whether it was automatic, manual or remotely controlled, don't think about getting the cable out of the space station.
After completing this step, there was nothing left for Kuai San. Tianhe began to change orbits to a higher orbit, and the Kuai Jiu ship at the other end was not idle either. It opened the bottom cabin and released the ground station hidden in the belly of the ship.
The ground station placed in the cabin was in a disassembled state. The mechanical arm of Kuai Jiu took out the parts needed for the ground station one by one and assembled them together outside the ship. After a while, the main body of the ground station, which looked like a diving bell, was assembled.
Kuai Jiu also completed its mission. After accelerating away, another transport ship came over to fill the position and continued to assemble the ground station.
Two more transport ships flew nearby, but did not approach the ground station. Instead, they opened the cabin directly, took out the parts in the cabin, and then released several engineering boats, dragging the parts along the cable to fly more than 100 kilometers away from the ground station. Only then did they put down the parts and assemble them one by one on the cable. After a while, the simple low-orbit dock was completed with the efforts of the engineering boats.
At this time, the ground station was also completed. In addition to the main body of the ground station that resembles a diving bell, the assembled ground station also has a ring like a swimming ring on the outside. At first glance, it looks like a flying saucer tied to the end of the cable.
At this point, all preparations were completed. At the command of the base, the flying saucer started, pushing the ground station out of the synchronous orbit and slowly flying towards Jupiter's moon.
At this time, the cable was still roughly straight. The Tianhe No. 1 stuck in the synchronous orbit was like the foot of a compass fixing the center of a circle. The ground station at the other end drew a very large arc and slowly approached Jupiter's moon.
As the altitude decreased, the linear speed of the ground station became lower and lower, and it was gradually pulled by the gravity of Jupiter's moon and began to fall like a free fall.
At this time, the role of the flying saucer was no longer to push the ground station, but to support the ground station to prevent it from falling too fast.
The whole process lasted for more than three hours. In the end, the ground station was suspended steadily outside the atmosphere, about 140 to 150 kilometers from the ground.
Due to the effect of gravity, the cable has been pulled straight at this time. Tianhe is suspended more than 24,000 kilometers away, and the ground station is hanging below, swinging back and forth, which reminds people of the wrecking ball used to demolish a house.
Everything is ready, and the situation is reported to the forward base. Ye Han issued a command to change the track to Tianhe. Tianhe started the engine and slowly approached Jupiter at a stable low speed.
The ground station was pulled by the gravity of Jupiter and descended with the change of track of Tianhe. It soon entered the atmosphere and slowly fell to the ground.
At this point, the orbital elevator has been 80% successful. As long as the strength of the cable is not wrong, success is a foregone conclusion.
The critical moment was coming, and Ye Han could no longer stay in the base. He put on armor with a group of men and rushed out of the base at the fastest speed. He rushed to the base of the orbital elevator in one breath and stopped, looking up at the sky and watching the descending ground station.
When the ground station was still a few hundred meters away from touching the ground, Ye Han issued a new order to Tianhe. Tianhe adjusted the engine output and slowed down the descent of the ground station until it was only a few dozen meters away from the ground.
The ground station was so big and hung in the sky that it felt like it would be caught no matter where it hid.
Ye Han made a gesture to Zeng Rui, and Zeng Rui immediately passed the message. The aliens who came to help immediately flapped their wings and flew high into the sky to hold the ground station.
Tianhe continued to descend, and a group of aliens vibrated their wings to aim the lower end of the ground station at the base, so that the ground station was accurately stuck on the base.
Ye Han rushed over with the soldiers, turned on the locking device, and locked the ground station firmly... The locking device on the ground was not completely locked like the Tianhe, but the team could unlock it. If necessary, it could be unlocked at any time to let the Tianhe pull the ground station into space.
