Nine Hundred and Thirty-Four Sky Train
Ye Han didn't know whether Beidu had any intention of pitting the resistance organization, but he knew that Beidu had never let down its guard.
Not only was there a hidden mechanism in the locking device, but the design of the ground station itself also had hidden mechanisms. It had a fully enclosed structure, a thick outer wall, and its own power supply equipment. There were also several hidden arsenals inside!
If the resistance organization broke up, Ye Han would just take his men and hide in there, and the ground station would instantly become a firepower fortress. Unless the aliens used heavy weapons of the ship gun level, they would not be able to do anything to the ground station.
The successful landing of the ground station meant that the main project of the orbital elevator was completed, and the remaining tails were all minor details.
However, neither Ye Han nor the resistance organization had the idea of delaying the construction period. Ye Han led the soldiers to work overnight to finish the work, and commanded a large group of aliens to run around - open the ground station, pave the exit, and then use the building materials transported to Jupiter's moon to build two symmetrical simple platforms. At dawn, the main project was completed, and it could be put into use after the concrete dried.
At this time, the ground station has changed its appearance. Two symmetrical doors are opened on the diving bell. Outside each door, there are two straight electromagnetic tracks leading to the simple platform, which looks weird.
The aliens don't care whether the ground station is weird or not, let alone whether the concrete is dry or not. As soon as the project is finished, a group of aliens drive the bugs over.
They also know that the rail elevator can make ground-to-air communication simpler and more convenient, so this time they sent more carbon fiber vines than any other time.
The containers in the base have been used up long ago, and Ye Han can't let them take the vines back, so he can only organize the soldiers to receive the vines, classify 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, can we pile them here? What if it rains, won't it all be gone?"
"It's okay, it won't rain for a while, and it will be transported away at noon at most." Ye Han said.
Military engineering uses quick-drying cement. In the most extreme case, it only takes one to five minutes for the initial setting and five to ten minutes for the final setting.
The cement used for the platform is not that exaggerated, but the solidification time does not exceed one hour.
Luo Qi suddenly realized, thought about it and asked again: "Boss, I will go back to the center of the earth later, or..."
"Let's talk about it later." Ye Han said, "Just pay this wave first."
He thought it would not take long to harvest the vines, but he did not expect that the resistance organization would work hard after getting the order from Beidu, expanding the original planting area several times, plus several harvests during this period, the vines accumulated were not ordinary, so the car bug transport team ran again and again, Ye Han led the soldiers to work for a whole morning, and the piled vines were almost piled into a small mountain, and there was still a steady stream of car bugs rushing over.
Ye Han was also dumbfounded. Seeing that it was almost noon, Ye Han had to stop receiving, leaving two soldiers to guard the vines, and took others to the airdrop site.
While the ground was busy harvesting vines, the outside was not idle either. Several transport ships left the synchronous orbit and flew around Jupiter's moon Zero for more than ten circles before reaching the low-altitude orbit, and then flew to the designated coordinates for airdrop.
A few minutes later, the space train with a parachute tied to its tail landed successfully.
The alien strong laborers continued to use their strengths and worked together to lift the heavy trains back to the ground station, and then put them together. Ye Han led the team to assemble the trains.
The special design made assembly very simple. The four space trains were quickly assembled, and Ye Han immediately organized people to check the trains.
The assembled trains were like sausages cut in half by a knife. There was also a semicircular groove running through the front and back of the train. The soldiers drilled in and out of the train, on and under the train, and checked the shell, bottom, doors and equipment.
The space train is very heavy and the risk of airdrop is extremely high. Even if the fleet has had experience in airdropping heavy equipment many times, it still cannot guarantee the safety of the train.
But if it is not airdropped, the train can only be sent to Tianhe and then descended along the cable.
The distance is long and it takes time.
Maybe someone will say, why not send the train to the low-orbit dock? In that case, the train can reach the ground in 200 kilometers, and it is much safer than airdrop.
Although the idea is good, it is very impractical.
The orbital height of the low-orbit dock is only more than 200 kilometers. The spacecraft must maintain a sufficient speed at this height to remain stable on the orbit, otherwise it will fall into the atmosphere like a weight, so the transport ship cannot get close to the low-orbit dock at all.
Currently, the only human spacecraft that can hover in low orbit is the Skyhook with eight main engines.
So can't the Skyhook be used to send the train up?
Still no, because the eight engines of the Skyhook are all on the side of the warship, and the propulsion is a micro-nuclear explosion caused by lasers. It is very dangerous for such a heavy spacecraft to get close to the cable. Any operational error will cause the laser emitted from the reaction chamber to cut the cable.
Not only the Skyhook, but any spacecraft driven by a nuclear-powered engine must keep a sufficient safe distance from the orbital elevator.
With all the factors accumulated together, Beidu had to weigh them again and again and finally chose airdrop.
In order to ensure that there would be no problems, the fleet also specially deployed a few extra carriages, so that even if any were broken, there would be replacements to avoid delaying important matters.
After a while, the train's self-inspection and external inspection 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 took only half an hour to fill all the carriages.
Ye Han took the soldiers to carefully check the carriages to ensure that there were no aliens hiding in the carriages.
Everything was ready, but there was no departure ceremony or other irrelevant things. Ye Han simply announced the departure and announced that the rail elevator was officially put into operation.
The two rails started at the same time, and the heavy space train immediately floated up. The guide rope tied to the front of the train was tightened, slowly pulling the train into the ground station.
The two space trains entered the ground station at the same time, one on the left and one on the right. After entering the station, they went up along the inclined track. When they reached the top of the slope, they were already perpendicular to the ground. Then the chassis of the two cars were tightly buckled together. The grooves on the chassis were just stuck on the cable. The two cars became one car and climbed up along the cable like a bug attached to a tree.
It was not until this time that the aliens understood why the space train was designed to look like a large semicircle inside a small semicircle.
Looking at the train climbing higher and higher, Ye Han breathed a sigh of relief and suddenly felt that all his efforts were rewarded.
Not only that, he also had a lot of expectations in his heart, looking forward to the early completion of the orbital elevator on Earth... But without the raw materials, nothing would work, and his current task was to harvest the vines sent by the aliens first.
