What is the most convenient way for ordinary people to go to space for sightseeing?

The answer is simple - the hero in the previous chapter rides in a space elevator. Pen Γ— fun Γ— Pavilion www. biquge。 ο½‰ο½Žο½†ο½

However, this seemingly simple plan was not easy to achieve. This is a very huge project, with large investment and high technical requirements. Despite this, the chief designer of the space elevator, Yu / Oakley Ford, rose to the challenge and built a space elevator within 60 years, which can carry 30-50 passengers to 3 to 60,000 kilometers from the earth at a time.

--The idea of using a ladder to ascend to the sky has been around for a long time. The Bible says that in 2100 B.C.E., there was an intention to build a tower of Babel in Babylon out of bricks and tar. By 1900 B.C., Jacob, the ancestor of the Israelites, had a dream to ascend to heaven with a ladder, which was called "Jacob's。。。。。。

Therefore, the idea of building a tower of Babel, a ladder or a space elevator from the surface of the earth to the sky has been a long-term dream of mankind. Professor Ling of the Institute of Aerospace Special Materials said with confidence: "From the late 21st century to the middle of the 22nd century, the development of human high technology may be like building highways and railways, building a space elevator to transport a large number of people and a large number of materials to the sky. ”

Professor Woo Oakley Ford, a researcher at cosmic materials, also thought that "the time was ripe" and formally proposed a plan to build a space elevator and drew up a sketch.

The main material of Oakleyford's vision is precisely carbon nanotubes. Carbon nanotubes have good physical properties, the tensile strength is 100 times that of steel, but the density is only 1/6 of steel.

-- According to Oakleyford's vision, the elevator is staggeringly tall, reaching 3 to 60,000 kilometers, about 40,000 times the height of the world's highest peak, Mount Everest. Why build 3 or 60,000 kilometers high? This is the altitude of the spacecraft in geosynchronous orbit, which reduces the damage caused by the Earth's rotation to the space elevator. To support such altitudes, the space elevator has a longer cable of 9 to 60,000 kilometers, which is a quarter of the gap between the moon and the earth.

Despite the use of carbon nanotubes, the base of the space elevator will not be too small, and in order not to occupy valuable land resources, the space elevator will be built in the desert or on the sea. In order to reduce the use of conventional petroleum energy sources, the space elevator will mainly use solar energy (and a 3,000-meter cloud lightning effective safety receiving device). These solar panels will be installed at the terminal station in space, and the power generation efficiency will be high due to the absence of cloud cover.

According to the motor power and technology that may appear in the middle of the 22nd century, and taking into account the viewing needs and comfort of passengers, the speed of the space elevator is initially preset to 200 kilometers per hour, which is about the same as the speed of China's bullet trains. In this way, compared to a spaceship with a speed of tens of thousands of kilometers per hour, passengers can take a leisurely view of the scenery in the space elevator. However, if the speed is slow, the travel time will inevitably increase. According to the average speed of 200 kilometers per hour, it takes 7 or 5 days for the space elevator to reach the terminal of 3 to 60,000 kilometers, and it takes exactly half a month to make a round trip. If you stay for a few days at the terminal, the travel time is even longer.

--Running in the air all the time, will the journey become monotonous? Oakley Ford said that if you keep staring out the window, it may be a bit monotonous, after all, the scenery of space does not change much; The high-altitude telescope offers an unobstructed view of mountains, rivers, oceans and even the pyramids of Egypt and the Great Wall of China. For example, if you look at the changes in the atmosphere within 1,000 kilometers, and when you go to space 1,000 kilometers away to see the changes of the sun, moon and stars, the feeling is completely different from that in the low sky. At the terminal, passengers see the full view of the Earth, which is slightly larger than the Moon. As the elevator rises, passengers can also feel that their bodies are getting lighter and lighter, and they can float freely in the elevator when they reach the terminal, which is a state of weightlessness.

According to Oakleyford's vision, the space elevator will be like a small space hotel, divided into several small cabins, where viewing, entertainment and rest will be mainly carried out. The space elevator can carry 30-50 passengers at a time, with several passengers sharing a separate small cabin. There are a variety of entertainment facilities in the cabin to pass the long journey to space. Of course, there are also corridors in the elevator where everyone can visit each other.

Don't think that Oakley Ford's plan is just a picture on paper, he has a strong international consortium and companies behind him. According to the plan announced by the Aerospace Administration, this space elevator will take 40-60 years and is expected to be completed in 2088-22 AD, with a total investment of more than 100 billion US dollars. Once completed, the elevator ride to the city won't be too low, but it's much cheaper than a 21st-century private space tour. Oakley Ford said that due to the rapid development of science and technology in the future, the construction cost of the space city is expected to be lower than expected.

--Why is it the most convenient for ordinary people to take the space elevator? In addition to the huge cost of flying a spaceship to space (about 3 to 60,000 kilometers above the ground, an altitude of 60,000 kilometers above the ground, which only billionaires can afford), spacecraft travel is very arduous and has to go through an unbearable process of acceleration and deceleration. The average person has to fly in a space vehicle and endure months of grueling training before traveling to space. However, once built, the space elevator can be used repeatedly and has a large number of passengers, so that the cost per traveler per trip will quickly come down. Space can rise at a constant speed so that visitors don't need to take part in long periods of special training before taking off.

Elevator travel to space, dreams of the past, reality of the future. The development of technology is limitless, can you imagine what will happen tomorrow? Maybe in the near future, we and the male and female protagonists of the book will be able to board the elevator and have a walk-and-go trip!

--Lucy didn't take the elevator to Space City, she was at the satellite ground station with her family and work. As soon as he got to work the next day, Ling Xiao called Lucy, the mechanic assistant of "Aerospace 2", and made an appointment. At the same time, "White Cloud Knight" and Liu Qing both drove to Lucy's house, and Lucy's uncle, Mike the Fishman, was ordered to go to the Devil's Triangle region of Bermuda, and only her mother was at home.

As soon as the "White Cloud Knight" entered the door, he first introduced himself, saying that it was Liu Qing's current boyfriend - that is, Professor Ling's latest research and development can also be said to be a positive "replica" of Oakley Ford's life spores; --The Lucy sisters are said to have been born with a negative life spore "replicant" (-- it is said that she and Lily will also be cyborg cold-faced female killers who explore outer space).

Mary was very happy when she heard this, and said, I said that I haven't seen Ms. Liu for many years, otherwise I don't know her so well, hello!

Okay, okay, I miss you and Mike, too. Liu Qing said.

yes, she suffered a lot to interview us, and if it weren't for her, maybe Mike would still be lying on his stomach in Monster Lake.

That's the credit of the police, and I'm just running errands.

Do you think it's easy to run errands, don't forget that you had a big belly at the time. Come to think of it, your child should say that he is the same age as our Lucy?

The kid didn't keep it - this doesn't teach "cloning" a "White Cloud Knight"。。。。。。 I now want to write a book about genius. Lucy is said to be a brilliant genius in the fields of painting and aerospace design。。。。。。

According to their nonsense, she is just a general assistant to the special materials of the universe - mainly space technology, and occasionally makes some astronomical observations.

Have you seen anything new in the near future?

It's like- what, little Lulu is having trouble with her research? Mary was vigilant.

No, I just wanted to learn about her career and family.

Hey, don't talk about family, she's a big girl of eighteen or nineteen, she doesn't even have a boyfriend, she is with her mother all day long, and she nests in her boudoir after work, and she doesn't know what she's tinkering with.

Has there been any recent mood change in her?

She's just like that, depressed, with a cold face and doesn't like to talk to people. Actually, she was quite lively and cheerful when she was young. Most of the reason for the formation of her character is me, I have locked her at home since she was a child, and I sent her to school when she was more than ten years old, and she developed her loneliness and arrogance. But I can't help it, her sister is lost, how dare I leave her alone in school。。。。。。

Mary said, her eyes reddening. Liu Qing knew that she was sad again, so she said: Let's talk about it here today, and I and the "White Cloud Knight" will come again when we have time in the future. Liu Qing and the "White Cloud Knight" left, Mary thought to herself, the "White Cloud Knight" who came with Ms. Liu was so sensible and handsome, it would be good if Xiao Lulu married him, and when Xiao Lulu and her uncle came back to discuss with him.

In fact, Mary has never forgotten what happened in Monster Lake more than 20 years ago, it was like a nightmare, it has been haunting her, making her unable to calm down and unable to face it. At that time, when interviewed by reporters and investigated by the police, she flatly denied what happened, however, she really could not confirm what she experienced when she miraculously returned to the hotel three days after her disappearance. Those three days were only a brief moment for her, and in that moment she had a dream that she had gone to a place she had never been, as if it were another world, which she could not describe in words, and those half-human, half-beast "lizardmen". The "lizardmen" are about 1 meter tall, have a pair of large red eyes, are covered in green scale armor, and only have 3 fingers on each hand. They lay her flat on a weird bed that seemed to float in weightlessness, and a "lizardman" courted her。。。。。。

Thinking of this, Mary still has a feeling that the past is unbearable.
