"Mars is too far away, and it's certainly not as convenient as the Moon." Xu Zhengping said, "I have thought about the plan to land on Mars this time, with the school as the lead, organize 10,000 people, not only to land on Mars, but also to build a beam channel generator in Martian orbit, as well as a permanent base on Mars, so as to pave the way for the future development of Mars." ”

"Ten thousand! It does take so many people, and we have the ability to do it. Fan Xiaoming said.

"Nice plan." Su Zhe said.

The three of them discussed the landing on Mars for a while, and it was tentatively determined that they would land on Mars around December.

And Su Zhe, Fan Xiaoming, and Xu Zhengping went together.

After talking about the landing on Mars, the three of them talked about the Sanmen plan and the development of the moon.

After ending the call, the time for Su Zhe and Fan Xiaoming to be in orbit was almost up.

At this time, the main engines of the solar energy collection station and the light energy transmission station in synchronous orbit were started.

At the same time, countless blue beams of light were shot out of the earth, and these blue beams irradiated the solar energy collection station and the light energy transmission station without interruption.

Driven by the main engine, the two were out of synchrony orbit one after the other.

Fan Xiaoming looked at the countless blue beams of light and sighed: "It's just us, if it were those small countries, it was estimated that this amount of energy would not be able to provide it." ”

"That's the truth!" Su Zhe said as he looked in the direction where the countless blue beams were coming from.

In the past, when you look at the country from space, the whole piece is bright, but now it is completely dark.

"This is just one time, and there will be a steady stream of cheap energy available in the future." Fan Xiaoming said.

The two looked at the surface for a moment, then adjusted their attitudes to look at the accelerating solar energy collection station and light energy transmission station.

The destination of the solar collection station is the orbit of Mercury, which is 92 million kilometers away in a straight line.

In the beginning, it was necessary to rely on the continuous replenishment of energy from the outside to accelerate.

However, as it gets closer to the sun, the solar energy it collects can be used for its own use, and there is no need for external supplementary energy.

Compared to solar energy collection stations, solar energy transmission stations need to continuously supply external energy and consume much more energy than solar energy collection stations.

After all, the destination of the light transmission station is no longer on the ecliptic surface.

After just a moment of watching, the solar energy collection station and the light energy transmission station have flown far, far away.

The two could only see two shining bright spots.

At this time, the time for the two to be in orbit has arrived.

The two began to fly towards the Blue Sparrow flying saucer docked in synchronous orbit.

In the Blue Sparrow UFO in the beam channel, Su Zhe and Fan Xiaoming were sitting on their seats, and their armored helmets were displaying images of the solar energy collection station and the light energy transmission station flying.

At this moment, both are more than a million kilometers away from the Earth, the former has reached a speed of 1,000 kilometers per second, and the latter has reached a speed of 1,500 kilometers per second.

And the two are still accelerating at an acceleration of 100 g and 150 g.

In the end, the former flew at a speed of two thousand kilometers per second, and the latter at a speed of three thousand kilometers per second.

"To be honest, I can't wait." Fan Xiaoming said, "If you want to talk about what is limiting the speed at which we can develop the solar system now, it is not technology, not resources, not that there are not enough people, but energy, for now, it is energy that limits our ceiling." ”

"Yes!" Su Zhe said.

"That's right! The space agency has built a new space station, so let's take this opportunity to go and have a look! Fan Xiaoming said.

During this time, they were not idle, and neither were the space agencies and relevant departments.

The space agency took the lead in building a brand new space station in orbit at an altitude of 500 kilometers above Earth.

To be honest, it's a bit inappropriate to call it a space station, but it's still called a space station, and it's called the Sky Space Station.

With a total mass of one million tons, it is capable of accommodating 30,000 people for a long stay.

As far as he knew, when they were planning to land on the moon and the simplified version of the heavy photonic aerospace engine had not yet been developed, the space agency was planning and making preparations.

To say that the strength of the country is strong, the construction of the transport belt of the Sky Space Station with a total mass of one million tons took only a month and a half as soon as it was emptied.

The Sky Station is a long giant in shape.

It is three kilometers long, eighty meters wide and fifty meters high.

The main ones are all kinds of laboratories.

"Yes! I really need to go and see it, it's been a week since the construction was completed, and I haven't been there once. Su Zhe said.

During this time, they were busy with the Sanmen program, and every time they went up and down space, they often saw the Sky Space Station.

Relative to schools and research centers, the space agency, or the country, is really powerful.

At the time of the construction of the Sky space station, there were 30,000 professionals in orbit and 100,000 remotely controlled humanoid robots.

Without such strength, it would not have been possible to complete the construction of the Sky space station in a month and a half.

"Yes!" Fan Xiaoming said, "In five minutes, we will be able to get out of the cabin." ”

Five minutes later, Su Zhe and Fan Xiaoming stood in front of the opening hatch in armored spacesuits.

After the hatch was fully opened, the two flew out with a slight leap.

After the two of them flew out of the beam channel, they adjusted their attitude and looked at the Blue Sparrow flying saucer in the beam channel behind.

When the Skeet flies out of the Blue Sparrow, its altitude is 800 kilometers, and the Skeet is slowing down at this time.

Su Zhe looked at the fast altitude displayed on his helmet, as well as the Sky Space Station, and said, "There are still two hours until dinner, don't delay dinner." ”

The main engine of his and Fan Xiaoming's armored spacesuit did not start, and the speed of their flight was constantly increasing due to the influence of the earth's gravity.

As for the location of the Firmament space station, the straight-line distance from them is 9,000 kilometers.

"I'm going to have a good walk around the Sky space station, as for dinner, I can eat it there, the space meal was still eaten when I landed on the moon, and now I kind of want to eat it, such as sauce radish, potato roast beef." Fan Xiaoming said.

"Stay on the Sky Station for dinner, when are you going to go back?" Su Zhe asked.

At this time, the main engine of the two men's armored spacesuits started and began to fly towards the Sky space station.

The upgraded armored spacesuit not only has a greatly improved battery life, but also has an automatic cruise function.

As long as the destination is selected, the armored spacesuit can automatically optimize the flight path to fly there in the most time-saving and safest way.

"The size of the Sky space station is equivalent to ten 100,000-ton aircraft carriers, how can such a large space station be able in one or two hours, I think about it, we will go back at eleven o'clock in the evening." Fan Xiaoming said.

"Eleven o'clock is too late, don't forget that we have to get up early tomorrow." Su Zhe said.

At around 4 a.m. tomorrow, the solar power collection station will reach its destination, which is the orbit of Mercury.

The light transmission station then arrives at its destination.

They are involved in commissioning.

You know, this is the first attempt at the light pillar project.

"Yes! I forgot about it. Fan Xiaoming said, "Then go back at nine o'clock, and it will be almost the same if you can sleep for six hours." ”

"Good! Then go back at nine. Su Zhe said.

Five minutes later, an elongated behemoth appeared in front of the two.

The closer you go, the more huge it feels.

In the distance, the two saw that the docked platform was full of people, all of whom were wearing indoor spacesuits.

As the distance approached, the cheers of everyone sounded in the ears of Su Zhe and Fan Xiaoming.

"Warmly welcome Professor Su and Professor Fan to visit the Sky Space Station."

"It was an honor for me to meet Professor Su and Professor Fan."

"This armored spacesuit is so powerful, I really want to equip it sooner."

……

Su Zhe and Fan Xiaoming came to the platform, and the people who greeted them were either staff of the Space Agency, or teachers and students from other universities, among which they were most familiar with Professor Si Wenbo of Qing University.

After the two greeted everyone, the two entered the Sky Space Station under the leadership of Si Wenbo.

The two first took off their armored spacesuits and began to visit them in indoor spacesuits.

The Firmament space station is fifty meters high and is divided into six floors, including work areas, entertainment areas, rest areas, and so on.

The workspace is mainly the lab.

Su Zhe and Fan Xiaoming followed Si Wenbo to visit.

The first place to visit is the rest area.

The rest area is simply a place where people sleep.

Everyone has a small private room.

This small single room is three meters long, two meters wide and three meters high, and it has a bed, chairs, table, and so on.

Of course, these things are different from those on the ground, they are fixed.

Si Wenbo looked at the bed in front of him and said: "These single rooms are actually used now, when your light pillar project is almost completed, the energy problem is solved, and the armored spacesuit can be popularized, we will be able to travel back and forth between the ground and the space station every day, after all, it will only take a few minutes for us to go up and down." ”

Now, everyone stays on the space station because of the energy shortage.

When you have enough energy, you can get on and off in an armored spacesuit.

Who would want to stay in space at that time.

Unless it is an experimental need, they are not willing to stay in space warfare.

Fan Xiaoming nodded and said, "The energy will soon be able to be used freely, and the armored spacesuit will soon be available to everyone." ”

"Five hundred kilometers! It's quite convenient to get on and off in an armored spacesuit. Su Zhe said.

Next, visit the entertainment area.

There are cinemas, chess and card rooms, etc., and most of them are game cabins.

Now the virtual universe is starting to partially open, and people can play games, learn knowledge, and so on in the virtual universe.

After visiting the entertainment area, the three of them came to the work area, and the first laboratory they visited was Si Wenbo's.

According to Si Wenbo, he took his entire research team to the space station.

"I envy you!" Si Wenbo said, "This Sky space station is what our universities have asked the space agency to build with the power of the country, then like you, do it yourself, I have heard, your school is going to build a space city in space that can accommodate one million people, who is the test city of Penglai Space City, as for the same level as the Sky Space Station, you have completed the design, and are in the process of manufacturing, just wait for the completion of your three-door plan, you will build three in an orbit at an altitude of 800 kilometers, and build a stronger hadron collider in space, And many, many more. ”

"This can't be helped, who told us to stand on an innate advantage." Fan Xiaoming said with a smile, "Besides, when the five beam channels built by the space agency are completed next year, you colleges and universities will not be able to play freely, and it is not up to you to do what you want." ”

"Then we have to wait until next year, it's too late!" Si Wenbo said with some envy, "The construction of the permanent lunar base in your school has not yet been completed, and you have begun to plan to go to Mars, and you will land with 10,000 people, not only landing, but also building a permanent Martian base and beam channel generator." Ay! I can't compare to you. ”

"This ...... Even you know this, it's spreading very fast! Fan Xiaoming sighed.

"Isn't it fast! Your school is giving half of it, which is 5,000 places. Si Wenbo said, "Everyone is competing for a place to go to Mars." ”

"Okay!" Fan Xiaoming nodded.

As he spoke, the three of them toured the laboratory and discussed related projects.

The reason why these laboratories were built in space was to repeat all kinds of experiments on Earth in a microgravity environment.

This is the most basic, and then there is the research of science and technology.

Soon, it was time to finish eating.

The three of them came to the cafeteria.

Fan Xiaoming got the space meal he wanted.

After eating, Si Wenbo said: "In this kind of microgravity situation, it is not very convenient to eat, drink, go to the toilet, etc., we should simulate the earth's gravity, so that there is no difference from the earth, and we can live in space for a long time." ”

"This ...... At present, gravity is simulated without centrifugal force simulation or continuous acceleration simulation. "As for the rest, it is almost impossible to achieve at this stage." ”

Fan Xiaoming and Si Wenbo nodded.

"We humans are quite fragile and can only survive in the same environment as the earth." Fan Xiaoming said with emotion, "If you don't have oxygen, you can't do it, air pressure, water, gravity, temperature, etc., if you lack one, you either die immediately, or you don't die after a while, even if you don't die, there will be problems." ”

"There is no way around it, who told us to be born on the earth and grow up on the earth." Si Wenbo said.

Su Zhe nodded and said seriously: "It is foreseeable that if human beings want to go out of the earth and go to the starry sky, they must either change themselves to adapt to the cosmic environment, or change the environment and make their environment the same as the earth." ”

"What did you say!" Si Wenbo thought for a while and said, "Just change yourself!" If you think about it, you can know that the first generation of transformation may still think of itself as a human being, and by the second or third generation, it is estimated that they will not think of themselves as human beings, so that they will not feel that they are human beings either mentally or physically, and they will ...... by then."

"I think so too." Fan Xiaoming nodded.

Su Zhe nodded and said, "Then you can only change the environment!" ”

After chatting for a while, the three of them left the dining room to continue their visit to the Firmament space station.

It wasn't until nine o'clock in the evening that Su Zhe and Fan Xiaoming left.
