Ye Han didn't know whether Beidu had the idea of tricking the resistance organization, but he knew that Beidu had never let down its guard.
Not only does the locking device have hidden mechanisms, the design of the ground station itself also hides mechanisms, with a fully enclosed structure, thick outer walls, its own energy supply equipment, and several hidden arsenals inside!
If the resistance organization breaks out, Ye Han only needs to hide in with a group of men, and the ground station will instantly turn into a firepower fortress. Unless the aliens use naval gun-level heavy weapons, don't even think about it.
What about ground stations.
The successful landing of the ground station means that the main body of the orbital elevator project has been completed, and the remaining parts are just corners.
However, neither Ye Han nor the resistance organization had any intention of delaying the construction period. Ye Han led the soldiers to put in the finishing work overnight, directing a large group of aliens to move smoothly - opening the ground station, paving the exit,
Then use the building materials that were transported to Jupiter in advance to build two symmetrical simple platforms. At dawn, the main work will be completed and they can be put into use after the concrete is dry.
At this time, the ground station had changed its appearance. Two symmetrical doors were opened on the diving bell. Outside each door, there were two straight electromagnetic tracks leading to the simple platform. It looked strange.
The aliens don't care whether the ground station is strange or not, let alone whether the concrete is dry or not. As soon as the project here is completed, a group of aliens over there will drive the car bugs over.
They also know that orbital elevators can make ground-to-air communication easier and more convenient, so this time they sent more carbon fiber vines than before.
The containers in the base have long been used up, and Ye Han can't let them take the vines back, so he can only organize the soldiers to receive the vines, sort them according to quality after inspection, and temporarily pile them near the ground station.
Luo Qi found an opportunity to get close to Ye Han: "Boss, is it okay to pile it up here? What if it rains and it's all over?"
"It's okay, we won't be able to get it down for a while, and we'll transport it away at noon at most," Ye Han said.
Military engineering uses quick-drying cement. In the most extreme cases, the initial setting only takes one to five minutes, and the final setting takes five to ten minutes.
The cement used on the platform is not that exaggerated, but the setting time does not take more than an hour.
Luo Qi suddenly thought about it and asked again: "Boss, I will return to the center of the earth in a while, or..."
"We'll talk about it later," Ye Han said, "Let's just pay this one first."
He thought it wouldn't take long to finish harvesting the vines, but he didn't expect that after the resistance organization got the order from Beidu, they worked hard to expand the original planting area several times, and they harvested several more crops during this period.
Back home, the accumulated vines were not as large as usual, so the vehicle transport team made one trip after another. Ye Han and the soldiers were busy all morning. The accumulated vines were almost piled up into a hill, but there was still a steady stream of vehicles.
The insects are coming.
Now Ye Han was also dumbfounded. Seeing that it was almost noon, Ye Han had to stop receiving the goods. After leaving two soldiers to guard the vines, he took the others and rushed to the airdrop site.
While the ground was busy collecting vines, there was no idleness outside. Several transport ships left the synchronous orbit and flew around Europa for more than ten times before reaching low-altitude orbit. They then flew to the designated coordinates to carry out airdrops.
A few minutes later, the sky train with a parachute tied to its tail successfully landed.
The strong alien laborers continued to play to their strengths and worked together to lift the heavy trains back to the ground station. They placed the trains end to end, and then Ye Han led the workers to assemble the trains.
The special design made assembly very simple. The four sky trains were quickly assembled, and Ye Han immediately organized manpower to inspect the trains.
The assembled train is like a sausage cut vertically and divided into two halves. There is a semicircular groove running through the front and rear at the bottom of the train. The soldiers drilled in and out of the train, on and off the ground, regardless of the car body or the car.
Check all the bottom doors and equipment.
The sky train is very heavy and the risk of airdrop is extremely high. Even if the fleet has many experiences of airdropping heavy equipment, it still cannot guarantee the safety of the train.
However, without airdrop, we can only send the train to Tianhe, and then descend all the way along the cable. The distance is long and it will waste time.
Some people may say, why not send the train to a low-rail terminal? In that way, the train can reach the ground after traveling 200 kilometers, and it is much safer than airdrop.
Although the idea is good, it is very impractical.
The orbital altitude of the low-orbit dock is only more than 200 kilometers. The spacecraft must maintain sufficient speed at this altitude to remain stable on the orbit, otherwise it will fall into the atmosphere like a weight, so the transport ship cannot approach the low-orbit dock at all.
Currently, the only human spacecraft that can hover in low orbit is the Skyhook, which has only eight main engines.
Then can’t we use the Skyhook to send the train up?
It still doesn't work, because the eight engines of the Skyhook are all on the side of the battleship, and the propulsion force is a micro-nuclear explosion triggered by a laser. It is very dangerous for such a heavy spacecraft to get close to the cable. Any operation error will cause the laser emitted from the reaction chamber to be damaged.
Risk of cutting the cable.
Not only the Skyhook, but also any spacecraft powered by a nuclear-powered engine must keep a sufficient safe distance from the orbital elevator.
Various factors accumulated together, and Beidu had to weigh it again and again, and finally chose the airdrop.
In order to ensure that there would be no problems, the fleet also specially invested a few extra carriages, so that even if they were broken, they would be replaced, so as not to delay the main business.
After a while, the self-inspection and external inspection of the train were all completed, and no problems were found. The site immediately began to move the vines. The aliens once again played a major role and contracted all the loading operations. It only took half an hour to transport all the vines.
The carriage is full.
Ye Han led the soldiers to carefully check the carriage to make sure there were no aliens hiding in the carriage.
Everything was ready, but there was no departure ceremony or other irrelevant things. Ye Han simply announced the departure and announced that the orbital elevator was officially put into operation.
The two rails were started at the same time, and the heavy sky train immediately levitated. The guide cable tied to the front of the train was tightened, and the train was slowly pulled into the ground station.
Two space trains, one on the left and one on the right, entered the ground station at the same time. After entering the station, they went up along the inclined track. When they reached the upper end of the slope, they were already perpendicular to the ground. Then the chassis of the two vehicles were locked together relative to each other. The grooves on the chassis
It happened to be stuck on the cable, and the two cars became one car, climbing up the cable like a bug clinging to a tree.
Only then did aliens understand why the space train was designed like a large semicircle within a small semicircle.
Looking at the train climbing higher and higher, Ye Han breathed a long sigh of relief and suddenly felt that all his efforts had been rewarded.
Not only that, he was also full of expectations in his heart, looking forward to the early completion of the orbital elevator on the earth... But without the raw materials, everything was useless. His current task was to collect the vines sent by the aliens first.
