Everything is normal, Ye Han stretched his waist and stood up: "Let's go, leave one person on duty, and everyone else will go back to wash and sleep." ”

"Is this over?" Luo Qi's mind was a little confused.

He was called back by Ye Han temporarily, and he didn't have time to see the project plan.

Ouyang Ping stretched out his hand and dragged him up: "Let's go, it's going to be a few days, I'll be on the first shift first!" ”

Luo Qi's gaze fell on the screen, and he suddenly figured out what Ouyang Ping meant.

The spaceship travels between Earth and Europa, and the speed must not be slow, otherwise it will take too long to make a trip.

The speed of ordinary spaceships is very fast, not to mention fast transport ships, so fast that they can't get to the edge of Europa Zero, and they can't rely on it, and the gravitational force of Europa can't catch the spaceship so fast, it must be swept by, and I don't know where it flew.

Therefore, every spaceship flying towards Europa must slow down a few days in advance to reduce the speed to the point that Europa can catch it, so that it can successfully cut into orbit and circle around Europa.

This is the law of nature, and no matter whose ship it is, it must abide by, and the same is true for Kuaijiu and Cable.

The fast-nine ship that tows the cable is like a locomotive, but the cable is soft, and the fast-nine ship can slow down, but the cable must continue to float forward.

There are only two ways to slow down the cable, one is to turn around and throw the cable forward, and then the spacecraft slows down to pull the cable.

The second one is to use that one just now, and then the ship will be slowed down synchronously.

Beidu also found a few aerospace experts here, and everyone agreed that the second method was more reliable, so today's incident was born.

Now the ship and the cable are a bit fast, and it will take a few days to slow them down.

After figuring out his joints, Luo Qima slipped back to sleep, and the next day he slept full, so he got up and asked for the engineering plan of the rail elevator, and read it carefully from beginning to end, and finally had a score in his heart.

In the next few days, the most important task of the forward base is to pay attention to the progress of the deceleration, and the command room will not leave people 24 hours a day, for fear of problems with the cable.

Thankfully, everything went well, and a few days later, the speed of both ships and the cable dropped below the standard line at the same time, and by this time, they were also flying near Europa.

The two spacecraft flew to a stop in synchronous orbit, and while circling around Europa, they adjusted the orientation of the cables, to be specific, the two spaceships continued to keep their distance, keeping the cables roughly straight, and then the fast three ships slowly approached the Tianhe.

The Tianhe was no longer in its original position, and it was moved to the synchronous orbit of Europa in advance, and after the three ships approached, they directly spit out all the things in the belly of the ship and handed it to the Tianhe.

Tianhe receives the outer end of the cable, drags the fixture into the depths of the space station and secures it, and finally locks the fixture, and from then on, unless the fixture is blown up, it doesn't matter whether it is automatic manual or remote control, don't want to get the cable out of the space station.

After completing this step, there was nothing to do with the No. 3, and the Tianhe began to change orbit to a higher orbit, and the Kuai-9 ship at the other end was not idle, opening the bilge and releasing the ground station hidden in the belly of the ship.

The ground station placed in the cabin was in a state of disassembly, and the mechanical arm of the fast nine ships took out the parts needed for the ground station one by one and assembled them together outside the ship.

The Kuai-9 ship also completed its mission, and after speeding away, another transport ship approached to fill in and continue to assemble the ground station.

There were also two transport ships that flew nearby, but did not get close to the ground station, but directly opened the cabin, took out the parts in the cabin, and then released a few engineering boats, dragged the parts along the cable, and flew to a place more than 100 kilometers away from the ground station, and then put down the parts and assembled them one by one to the cable, and 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, and in addition to the main body of the assembled ground station, which resembled a diving bell, it was also covered with a ring sleeve like a swimming ring, which looked like a flying saucer tied to the bottom of the cable.

At this point, all the preparations were completed, and the base gave an order, and the flying saucer was activated, pushing the ground station out of the synchronous orbit and slowly flying towards Ganymede.

At this time, the cable was still roughly straight, and the Tianhe poked in the synchronous orbit was like the foot of the compass fixed to the center of the circle, and the ground station at the other end drew a large arc, slowly approaching Europa.

As the altitude decreases, the linear velocity of the ground station becomes lower and lower, and it is gradually pulled by Europa's gravitational pull and begins to fall like a free fall.

At this time, the role of the flying saucer is no longer to push the ground station, but to support the ground station so as not to fall too fast.

The whole process lasted more than three hours, and finally the ground stood firmly outside the atmosphere, about 145 kilometers above the ground.

Due to the effect of gravity, the cable at this time has been pulled straight, the Tianhe is suspended more than 24,000 kilometers away, and the ground station is hanging under the head and dangling vigorously, reminiscent of the broken ball used to demolish the house.

Everything was ready, the situation was reported to the forward base, Ye Han gave the Tianhe an orbit change order, and the Tianhe started the engine and slowly approached Ganymede at a steady low speed.

The ground station was pulled by the gravitational pull of Europa, descended as the Tianhe changed orbit, and after a while, it burrowed into the atmosphere and slowly fell to the ground.

At this point, the rail elevator has been successful, as long as the strength of the cable does not go wrong, the success is nailed.

The critical moment was coming, Ye Han couldn't continue to stay in the base, and with a group of subordinates wearing armor, he rushed out of the base as fast as possible, rushed to the base of the rail elevator in one breath before stopping, looking up at the sky and looking at 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 the Tianhe, and the Tianhe adjusted the engine output, and the ground station slowed down its descent until it was only a few dozen meters away from the ground before maintaining suspension.

The ground station is so big that it hangs in the sky, and there is a feeling that no matter where you hide, you will be detained.

Ye Han gestured to Zeng Rui, Zeng Rui sent a message, and the aliens who rushed over to help immediately flapped their wings and flew high and held the ground station in the sky.

As the Tianhe continues to descend, a group of aliens vibrates their wings and aligns the lower end of the ground station with the base, causing the ground station to jam at the base without error.

Ye Han hurriedly rushed with the soldiers, turned on the locking equipment, and firmly locked the ground station...... The locking equipment on the ground is not completely locked like the Tianhe, but can be unlocked in the team, and if necessary, it can be unlocked at any time, allowing the Tianhe to pull the ground station into space.
