How to carry 100,000 people to break through the earth's gravity and provide a safe living space for 70 years is the most difficult problem to solve in the entire migration.

After visiting the Survival Research Center, Carlson took John and his party to take the elevator again and continue to descend.

After a descending time of several tens of seconds, the elevator stops.

As soon as the door opened, John stepped out of the elevator and was immediately shocked by the sight in front of him, and the others behind him were all like him, one by one, with long mouths and couldn't believe what they were seeing.

Carlson on the side smiled slightly, obviously knowing that John would have such a reaction.

"Sir!" Carlson shook John up slightly, "This is the Space Station and Craft R&D Center. He introduced.

John Mumu nodded, and the scene in front of him was really incredible.

The vast underground base was as bright as day, and under the illumination of the light, a behemoth stopped quietly in the base.

It's a lot bigger than the Pentagon where John had just been.

The entire behemoth is made up of four huge rings, each of which is connected by four cylinders, and the outermost ring has two strange cone-shaped devices that look like two tails.

"Is this the space station?" asked John, dumbfounded.

"To be precise, it's just a model. Carlson explains: "The main station is made of wood, with a total area of 8.756 million square meters, and the outermost ring is a storage center, a plant center, a breeding center, and an oxygen production center...... The two cones outside the outermost circle are power units, the second and third rings are residential and leisure areas, and the innermost ring is the command center, the entire space station can accommodate 8,000 thousand people, of course, this is the main station so it can accommodate fewer people, and the number of people in other space stations can reach 23,000 people. ”

"I have a question!" John asked, pointing to the space station, "how do we get it into space with such a large area and weight?"

It is difficult for John to imagine how to transport a space station larger than the Pentagon into space, you must know that the strongest launch vehicle, Saturn 5, has a carrying capacity of 100 tons, but the space station in front of him is at least 10 million tons, and such a weight cannot be carried into space even if ten Saturn 5 launch vehicles are tied together.

"Sir, look at ......" Carlson took John and his party to the front of the space station, pointed to an interface and said: "The entire space station is composed of 166 boxes, which can be disassembled like a train carriage, and when it is built and operated, we will transport it into space one by one and reassemble it in space." ”

"I see!" John was an eye-opener, but he still had doubts: "Even if it is disassembled, a section has a lot of weight, and at present, our launch vehicle can carry a maximum weight of about 100 tons, and this section should exceed 100 tons!"

"Yes, the lightest section of the space station is 165 tons, the heaviest can reach 420 tons, and the power plant can reach 752 tons.

The Saturn 5 has a lunar orbital capacity of 45 tons and a low-Earth orbit capacity of 118 tons.

It is simply impossible to complete the transport task with such a conventional rocket, so we are experimenting with nuclear-powered rockets. Carlson replied.

"Oh, what's the result of the experiment?" John was surprised that Area 51 was actually working on a nuclear-powered rocket.

"At present, we have mastered the technology of nuclear fission rockets, and after dozens of experiments, nuclear fission rockets can fully undertake the carrying mission. Carlson further explained: "The larger the carrying capacity of a conventional rocket, the heavier its own weight, taking Saturn 5 as an example, a Saturn 5 has a take-off weight of more than 3,000 tons, while our nuclear fission rocket is three times as large, but it is comparable to its weight, and the carrying capacity is eight times that of it."

And we are now developing nuclear fusion power technology, if the research and development is successful, the carrying capacity of the rocket can be increased by about 5 times, and more importantly, if the nuclear fusion power technology is successfully developed, then we can develop space transport aircraft to undertake transportation tasks.

And our space station can also be powered by nuclear fusion, and then the space station can travel at as low as 8% of the speed of light, at this speed from Earth to Mars in only 65 days, then we can make short trips in space, and we can visit many planets in 70 years. ”

"Not bad. John nodded appreciatively, then suddenly asked, "How did those 100,000 people get on the space station?"

Transporting 100,000 people into space is a big challenge.

"We are developing a manned space vehicle, and after all these years of test flights, we can now carry 200 people into the space station in one aircraft, but I believe that the number of people will increase in the future as technology improves. ”

"Yes. John nodded, the problem was settled, and then asked, "When will the space station be finalized and start construction?"

Before building the physical object, it is common to make a replica of wood first, so that it is easy to alter and the cost is low.

"The current space station has been basically finalized, only a few still need to be improved, it is expected to start construction in 2000, 2050 no later than 2060 at the latest five space stations can be built, 2075 can all be put into space. Carlson gave the entire project timeline.

John couldn't help but sigh after hearing this: "I'll be 105 years old in 2075, and it seems that I won't see the space station go into space." ”

Carlson felt that John was regretting that he couldn't board the space station, so he immediately comforted: "Sir, although this space station is a replica, it is made according to the appearance of the real space station, and this space station is the main station, which is the government residence and the office and residence station of high-level government personnel, so we have also prepared a room for you inside, do you want to go in and have a look?"

"Oh!" John was a little surprised, although he knew that he would definitely not be able to take a space trip to the space station in his lifetime, but it was also a comfort to look at the room that Area 51 had prepared for him: "Lead the way, see what room you have prepared for me." ”

"This way, please!" Magnus immediately smiled and led the way.

Under the leadership of Carlson, John and his entourage walked into the space station, which is very large, with white as the main color, which looks concise and clear and full of technology.

Through the two passages, John and his party entered the third ring residential recreation area, and Carlson introduced to John and others as he walked: "The third ring of the main station is divided into four independent areas, one is the government office station, one is the high-level government residence, one is the Morgan family station, and the other is the Rockefeller family station. ”

Carlson said and led John and his party to the residence belonging to the Morgan family, and continued to introduce: "The entire station is divided into residential areas, leisure and entertainment areas, which can accommodate 1,000 people, and leisure and entertainment areas include theaters, bars, sports halls, libraries, art galleries, ....... ”

The bigwigs need to live in the empty space for at least 70 years, in order not to let the bigwigs get bored, the staff racked their brains to move the leisure and entertainment projects that can be moved to the space station.

That's why other space stations can accommodate 23,000 people, while the main station can only accommodate 8,000 people.

The 15,000 people who are missing have absolutely all their living space for the bigwigs.

Therefore, as long as humanity is not destroyed, this thing will always exist.
