The bridge suddenly fell silent, and Luo Qi nodded violently: "It's possible, it's very likely!" ”

He Lu said: "It's not a day or two that Europeans want a rail elevator, and it's not a day or two that the United States is worried about it......

"Yes, that makes sense!" Luo Qi nodded violently again, "For such a long time, the two track elevators have been built, and there must be a story about the failure to deliver, plus the matter of catching up with Mars...... Hehe, the European side can't agree with it if you want to. ”

Ye Han frowned and said: "I don't care how this rail elevator came about, I just want to know, just one elevator, how to distribute it in the future!" ”

Everyone wants to know the answer, who can answer?

At this time, Leishan was located over the northern hemisphere of Mars, and soon after, Leishan drilled into the shadow of Mars, and when the battleship came out of the shadows, the south pole of Mars came into view.

Ye Han and the others were surprised to find that the survey of the South Pole had ended, and there was no half of a figure in the entire South Pole.

Luo Qi's mouth was fast, his eyes were round, and he turned his head high: "Didn't you say that the South Pole has set a good location?" ”

He Lu raised his eyebrows: "Look at what this means, it should be a location first, and it's hard to say when it will be used." ”

"Focus on building the Arctic first, and then use the resources of the Arctic to build the Antarctic...... That's a good idea. Ye Han said.

From the earth to Mars, it can be as short as half a month, or more than two months, and the transportation cost is frighteningly high.

On the contrary, if the Martian resources can be used to build a Mars base...... There must have been some trouble at first, but as long as the resource development is on track, the cost or anything is not a problem at all.

Thinking of this, Ye Han suddenly realized that the withdrawal of the base group from the Antarctic may also have the factor of concentrating forces to develop Arctic resources.

Building Antarctic ...... with Arctic resources This may well be one of the costs of prioritizing the construction of the Arctic.

Maybe the northern capital will have to provide a rail elevator for the South Pole......

When Leishan turned back to the North Pole, the rail elevator had changed from vertical to flat, and the 20,000-kilometer-long cable was pulled straight by centrifugal force, like a crane rotor with only one blade tied to the North Pole of Mars, and like a red fruit connected to a straight and slender branch.

At this time, an air train had already left the space station, and it was like a small insect lying on a tree branch, slowly but surely wriggling towards the fruit.

In general, the space train only runs between the ground and the low-gauge terminal, but this does not mean that the space train cannot run to the space station.

"Why don't you leave the car in the dock?" One of the bridge officers said curiously.

"Do you need to ask?" He Lu's face was full of helplessness, "It's strange that there is still a place to put the train in such a long cable dock!" ”

Thinking about the internal structure of the low-orbit wharf, Ye Han felt that the low-gauge wharf must have been hollowed out to fit so many cables into it, and the wharf might be busy repairing.

20,000 kilometers is not close, it is equivalent to running half a circle around the earth's equator, and it takes the train three full days to land. To speed things up, the three sky trains on the space station departed one hour apart, and the small bugs on the branches went from one to three.

At the same time, the fleet continued to airdrop supplies into the Arctic, with engineers building three platforms near the platform with great efficiency, as well as a two-kilometer track along the cable.

The herringbone track starts at the platform and gradually extends towards the cable, leaning on either side of the cable a few hundred meters away from the platform, and ending along the cable for another kilometer.

This strange design attracted Ye Han's attention, and after some observation, he finally figured out the purpose of the herringbone track.

The space train is equivalent to a cylinder that is cut vertically, separated when it is on the ground, and closed when it is connected to the cable.

But those track elevators are all perpendicular to the ground, and Mars, which lies directly on the ground, is essentially different from the previous track elevators, and the method of the train landing naturally has to be changed, and the closing process that was originally carried out in the ground end is changed to the extended track.

Ye Han didn't know how many technical difficulties there were, but since the above had the courage to put the rail elevator in the North Pole, the technical difficulties that should have been solved must have been solved.

The more he pondered, the deeper he went, and suddenly he felt that the ground end of the Martian North Pole should be a little different, it seemed to be just a strong anchor.

The size of that thing is not small, the diameter accounts for more than half of the platform, and you don't need to ask to know that the strength is very high, but compared with the total mass of the rail elevator and the tensile force generated during operation, the ground end of about six meters seems to be a little lacking in strength.

Well, the ground side may be made of some special metal, maybe it's still a legendary alien formula!

In other words, I have been researching alien technology for several years, but except for the nuclear engine, I have never heard of any extraterrestrial technology used, and the research progress of the military seems to be a bit slow!

Just when the sky train was always crawling towards Mars, Ye Han finally received a notification from Jizhou: The asteroid belt task force led by Nanzhou has arrived in the asteroid belt a few days ago and is about to join the left-behind fleet, and it is expected that the fourth will head towards Ceres!

This news immediately attracted everyone's attention, not because everyone was too bored, but because the left-behind fleet had been hovering near Ceres, and converging with the left-behind fleet was equivalent to encountering an alien fleet.

Today is August 2nd, and if the Jizhou news is accurate, the asteroid belt task force fleet will encounter the alien fleet the day after tomorrow!

The success or failure of the Nanzhou ship group is not only related to the ownership of Ceres, but also to the success or failure of the exploration of Mars.

Ye Han immediately left Mars behind and ordered the Thunder Mountain to focus the camera on Ceres.

The panoramic helmet was very powerful, Ye Han only felt that the scenery in front of him had changed, and the sparks under his feet had disappeared, replaced by a pitch-black void.

Twelve pitch-black human warships were in front of Ye Han and the others, they were the twelve warships left by the task force in the asteroid belt, and all of them were covered by the camera.

When the Thunder Mountain returned, the Beihai was also ordered to return to Beiyuezhou, and there were only six human warships left in the entire asteroid belt, just three in Beidu and three in Washington.

These six warships are all the forces left by humans in the asteroid belt, and together they form the asteroid belt left behind fleet.
