Chapter 592
Wang Yifei's Desperate Situation, Panoramic Effect, Despair in Deep Space
Harbin, the Ice City, and Harbin Institute of Technology.
"Hey, where did Big Fish go? We can't get through to him on the phone, and he hasn't sent us any messages. Even if he's in seclusion, we can't just not contact him, can we?"
In the living room, Wang Yifei sat on the soft sofa and said with a troubled expression.
Her younger sister, Bai Doufu, was completely oblivious, entertaining herself on the tablet and ignoring her older sister.
As for the siblings Wang Junxian and Wang Sixin, they went out to play wildly.
At four years old, a child should be chasing chickens and dogs; how could they possibly stay at home?
Liu Xiaoli didn't pay any attention because she was taking care of her child.
Huang Huiru became pregnant again. Not long after the Qingming Festival, three days after Wang Duoyu announced his seclusion, Wang Junhong and his wife went to the hospital for a check-up and found that she was already more than five weeks pregnant.
Therefore, Liu Xiaoli will take care of Wang Ruoxi's child.
Actually, Liu Xiaoli usually takes care of the child, and Wang Ruoxi will be two years old in two months, so she's not young anymore.
Babies over six months old are generally easy to care for; babies under six months old are not.
"Xiaoli, you really don't care about your man anymore, do you?"
"Can I control this? Do you need your Big Fish Brother's help if you have something to do?"
"Sister Xiaoli, can you help me? Hehe~"
Wang Yifei immediately rushed over with delight, but before she could reach her mother's side, she heard a crisp and decisive refusal:
"I can't help, I have to take care of my child, and I don't have any money."
"No, Sister Xiaoli, you can't just stand by and watch someone die, can you?"
However, Liu Xiaoli didn't give her daughter a chance to pester her. She picked up Wang Ruoxi and went outside, leaving Wang Yifei staring blankly.
snort!
With May just around the corner, Hollywood is getting restless again.
As a star about to enter Hollywood, Wang Yifei naturally wants to take action.
Investing in the movie "Fast & Furious" may not necessarily bring her much profit.
If she wants to make big money, she still has to rely on her old father.
Unfortunately, her elderly father was in seclusion, so she didn't even have the chance to ask him for advice.
Ugh!
Los Angeles, Hollywood – the prelude to the summer blockbuster season is about to begin.
Before that, it was the off-season for Labor Day, or rather, a slightly popular period.
After all, some movies can achieve very good box office results during such a slow season.
For example, in May of this year, Paramount released "The Hangover"!
This movie is a low-budget comedy about a groom who has a bachelor party in Las Vegas with his three groomsmen two days before his wedding. After waking up from a hangover, he finds that his groom has disappeared.
Then the three groomsmen searched for clues by recalling their memories and found the groom.
The plot is simple, but the story is rich and engaging, making it a very interesting and surprisingly good comedy film.
Wang Yifei doesn't know yet whether this movie will be a hit, but even if she did, it wouldn't matter because Paramount isn't a publicly listed company, so she can't invest in it.
However, she needs to evaluate the film to decide whether to invest in 20th Century Fox.
This is simply because the company also released a movie during the May Day holiday: Kingdom of Heaven!
Most of the characters in the film are based on historical figures, so it's hard to say whether it will be successful or not in terms of box office performance.
Although The Hangover is a low-budget film, it has Paramount backing.
Although Kingdom of Heaven was a big-budget production, 20th Century Fox films are known for their inconsistent quality.
Therefore, Wang Yifei hesitated and thought about discussing it with her father.
Ugh!
However, at this time, her father was wandering in space.
The spacecraft is escaping Earth's orbit at speeds exceeding the second cosmic velocity, heading towards deeper into outer space.
Once it reached a suitable orbital position, the spacecraft slowly entered lunar orbit.
At this point, Earth's gravity weakens while Moon's gravity strengthens, and the flight trajectory gradually deviates from its initial elliptical orbit.
When the Earth enters a radius of only 66,000 kilometers from the Moon, the Moon's gravity becomes dominant, rather than the Earth's gravity.
At this point, the spacecraft's flight trajectory completely changed; it was no longer an ellipse around the Earth, but a hyperbolic orbit around the Moon.
Furthermore, the orbital plane gradually improved, no longer lying on the same plane.
There is no simple way to easily describe this process, whether from a mathematical or physical perspective.
Theoretically speaking, there are countless possible orbits in space, but there is only one orbit that consumes the least amount of energy.
Before Wang Duoyu and his group set off, or rather, before all those previous flight paths, they had all followed this calculated path.
Long ago, Wang Duoyu and his technical team had already found and calculated the Earth-Moon flight trajectory with the least energy consumption.
This is because interstellar travel is subject to interference from various forces, such as microgravity, propulsion and acceleration, cosmic radiation, micrometeoroids and space debris, gravitational gradient (tidal force), Coriolis effect, and so on.
Therefore, every time a spacecraft travels to the moon or returns to Earth, it is necessary to design one or more flight paths in advance, calculate the time and energy required, and anticipate any unexpected risks.
Because disturbances such as microgravity may be controllable, but micrometeoroids and space debris are uncontrollable.
Space may seem vast and empty, but it contains a large amount of high-speed moving micro-dust and man-made debris.
These objects travel at speeds of several kilometers per second, or even higher. If they collide with a spacecraft, they could cause structural damage, threaten mission safety, or even the lives of astronauts.
Therefore, many unexpected events need to be carefully considered.
"Reporting, Professor, we have now reached the entry point of the Earth-Moon transfer orbit and are about to enter the Moon."
Upon hearing this, Wang Duoyu nodded, but did not make any move.
The flight paths of spacecraft carrying out manned space missions are all pre-set.
Before encountering any danger, Wang Duoyu and the other six astronauts will not operate the spacecraft in any way.
The lunar transfer orbit entry point refers to the spatial location of the spacecraft when the engine shuts down during the third perigee maneuver; this is a term commonly used for chemical-powered spacecraft in the past.
Although the spacecraft used by Wang Duoyu and his team has now changed its energy source, the name remains the same.
The spaceship continued its rapid journey toward the moon at a speed exceeding the second cosmic velocity.
However, at this point, the distance was already very close, and they were slowly slowing down.
As time went on, the spaceship slowed down and flew toward the lunar surface.
And as it approached the lunar surface, the spacecraft's speed had already decreased significantly. Boom!
After a slight impact, the spacecraft finally landed slowly on the lunar surface and came to a steady stop.
At this moment, after confirming that they had landed safely, Wang Duoyu and his team immediately sent a signal to the command center on Earth to confirm their safe landing.
After finishing all the safety work, Wang Duoyu finally had a moment to take out his phone and take a selfie.
The subject of the photo is, of course, himself, but the background is the Earth seen through the spaceship's transparent window.
The enormous Earth, the scenes I witnessed firsthand, were completely different from the photos of Earth from the moon's perspective in textbooks.
The difference is huge!
Absolutely stunning!
Just like when the spacecraft left Earth and entered Earth orbit, especially geostationary satellite orbit, when he looked back at Earth, he felt a sense of awe and despair at the insignificance of humanity in the face of nature.
And when you see space, the 'bottomless blackness' is such a huge psychological shock that even 'a bottomless abyss' is not enough to describe it.
Some timid people have gone snorkeling at the beach, from the shallow waters of small islands to the deep sea outside, with the sheer cliffs and abysses in between, all of which are equally despairingly dark.
Many people are afraid of this kind of snorkeling, especially those who are seeing it for the first time.
But this kind of black is completely different from the panoramic black seen from space.
Astronauts standing in space, with their backs to Earth and facing the endless universe, experience a panoramic effect that can only be triggered after leaving Earth.
The brain will be temporarily unable to process the amount of information contained in this image, and at the same time, a series of concepts such as the universe, space, oneself, and humanity as a whole will be refreshed.
Many abstract concepts will become practical at this moment.
Wang Duoyu felt that his life had not been in vain.
He has a very strong mental fortitude, but he was still stunned for a second when he saw such a scene for the first time.
I'm already able to face it calmly now.
"Let's get to work!"
After taking the selfie, Wang Duoyu gave the instructions.
In fact, the other five astronauts already knew their missions, so they didn't need him to give them instructions.
In addition to the fixed mining mission, this space mission also includes several other experimental and exploration tasks.
Wang Duoyu's own task was to conduct reconnaissance.
He needs to acquire enough data, just like a civil engineering student, measuring everywhere.
At the same time, he also needs to obtain a sufficient number of experimental samples.
Once a result that meets the criteria is found, the next step is to establish a base on the moon.
Of course, establishing a base on the moon is not easy; the first problem to be solved is the lunar soil.
But none of this is urgent; let's take it one step at a time.
On the moon, Wang Duoyu and his six companions spent a total of seven days, a mission that lasted several days longer than their previous missions.
Before leaving, Wang Duoyu and his team placed several pieces of equipment in a specially made box, then dug a pit and buried it on the lunar surface.
This is an experiment to see how these devices placed on the moon will change when we come back next time.
Because there is various cosmic radiation in the universe, and the moon does not have an atmosphere to protect it like the earth, various cosmic radiations can pass through the moon.
One of the biggest potential risks of future lunar bases is high-energy particle radiation from space.
Astronauts will face two sources of radiation when traveling between stars and on the lunar surface: one is the Milky Way cosmic equipment, which serves as a continuous background radiation source.
Its ion velocity can reach close to the speed of light, but the flux changes relatively slowly and is modulated by the solar magnetic field and is inversely related to changes in solar activity.
Second, it occurs occasionally, but with a higher flux of high-energy solar particles, produced by solar flares or shock waves.
Its frequency of occurrence is positively correlated with solar activity, but predicting its timing and intensity remains difficult.
On their return journey, Wang Duoyu and his friends were quite bored, so they started discussing how to avoid cosmic radiation, including high-energy particles from the sun.
"We have already developed so many models about high-energy particles in space. Although we do not yet have data on their evolution over time, I believe that space radiation at depths of five meters below the lunar surface will not pose a radiation hazard to astronauts on duty."
"Moreover, we can also ensure that the radiation exposure they receive does not exceed the occupational or annual limits by frequently rotating astronauts."
"We might even develop better anti-radiation suits."
As science and technology advance, establishing a lunar base becomes increasingly urgent, and many technological products will gradually emerge.
Want Want Group is incredibly powerful and controls a massive amount of money.
However, this amount of money is indeed insignificant in projects such as deep space exploration and space tourism.
Perhaps after returning, Wang Duoyu really needs to consider allowing the Super Dollar Factory to continue expanding its business.
The United States is a huge malignant tumor.
Especially those capitalists, who will do anything for profit.
Starting in the 1980s, Reagan and his ilk, for the sake of their positions, the interest groups behind them, and to make the data look better, had to cut public services and reduce very good welfare spending.
For example, in healthcare!
So that's how the kill threshold came about.
Wang Duoyu needs money, and the Morgan Group has money. If he doesn't get involved with them, he doesn't know where else to get money.
Anyway, the super dollar factory has been around for over ten years, so making more money won't hurt.
"Not necessarily, Professor. We've conducted experiments before. All the cosmic ray particles that hit the lunar surface can interact with the lunar soil to produce a large number of secondary particles. The flux of secondary particles, especially neutrons, reaches its peak at about half a meter below the surface."
One of the astronauts objected:
"We all know that neutrons can easily reach radiation-sensitive organs inside the human body and cause complex damage."
"A depth of five meters below the lunar surface is not necessarily the safe shielding depth, so I believe the deeper the better, at least ten meters."
As for other high-energy particles from the sun, no one has discussed them.
Because the energy range of high-energy particles from the sun is relatively low, they are less likely to produce high-energy secondary particles and can be more effectively shielded by lunar soil.
Generally speaking, a shielding depth of a few tens of centimeters is sufficient, so there is no need for further discussion.
Clang!
At that moment, the entire spacecraft shook violently. Except for Wang Duoyu, the other five astronauts' expressions changed drastically, as if something extremely frightening had happened. (End of Chapter)
