The Three-Body Problem: The Most Competent Wallfacer of All Time

Chapter 169 Spaceship
Surprisingly, the planetary spacecraft in Moon City turned out to be a spacecraft powered by liquid fuel propellers.

This can be seen by looking at the aeroengine at the tail of the spacecraft.

The original scientific team responsible for building the spacecraft did not disband. When the concept map of the spacecraft in Moon City was released, some engineers also found that the propulsion system of the spacecraft was too powerful, but the space for storing fuel was too small.

Although there are no specific drawings or specific parameters of the spacecraft, engineers believe that it may take more than a year to fly to Mars based on the fuel reserves of this spacecraft.

Facing the doubts of the engineers, Burton, the newly appointed mayor of the moon city, declared that the spacecraft can fly to Mars in three months!

Some scientists and engineers scoffed at this, and did not hold much hope for the spacecraft in Moon City.

Burton ignored these doubts. He asked the PDC to settle the scientific research budget for Moon City for the next three years before they announced the detailed Mars plan.

The rotating chairman of the PDC is a little speechless. Your technical disputes have nothing to do with the PDC!

Then the PDC shied away and said that there was no money now, so Burton asked the PDC to sign a contract that would not default on the scientific research budget of Lunar City for the next three years.

The representatives of the PDC countries have a toothache. The "Declaration" stipulates that the PDC needs to continue to provide scientific research funds to Moon City, but for these veterans in the political circles, it has never been said that the arrears cannot be delayed or reduced year by year.

This is a detail that neither Jiang Yu nor Bill had thought of before. As the saying goes, there is specialization in technology. Burton, a management professional, discovered this loophole after he took office and designed this routine.

Once this contract was signed, the wishful thinking of all countries was overturned.

At least for the past three years, there is no reason to take advantage of Moon City.

Give Moon City three years, is there still a chance to hold them in the future?
But now that PDC has something to ask for from Moon City, they can only sign the contract first, and let's talk about the future.

After the contract was signed, Bill announced the Mars plan of Moon City as promised.

The way of announcement is to explain the origin of the plan to everyone in the form of a video.

The keynote speaker was Bill, who started with the first program.

Beale's team was the first to demonstrate the acceleration method used in the "Staircase Project", but they soon discovered that the space sail that dragged the spacecraft might have to be one-third the size of the moon.

And because it is the force of dragging, it is difficult to control.After approaching Mars, whether the space sail can be retracted smoothly is also a problem.

So Bill's team proposed another plan, installing a huge metal plate at the tail of the spacecraft.

When the hydrogen bomb behind the spacecraft exploded, the shock waves and radiation generated were absorbed by the metal plate at the tail of the spacecraft.The force absorbed by the metal plate is used as the driving force for the spacecraft to move forward.

However, after careful calculation, the members of the project found that this method was too slow.

The shock wave generated by the hydrogen bomb explosion will disperse in space. Even if the metal plate at the tail of the spacecraft is on the level of a square kilometer, it can get very little thrust.

Moreover, the larger the area of ​​the tail metal plate, the heavier the spacecraft will be, and more thrust will be wasted.

Moreover, the metal plate was difficult to install. After all, the diameter of the spaceship was only a few meters, and the widest part was only 40 meters. However, a metal plate with a diameter of several kilometers was dragged behind it, which looked like a thumbtack at first glance.

The key is that it is not practical, and it is not as fast as using traditional liquid fuel rockets.

So this problem goes back to the starting point. The spacecraft needs too much fuel to go to Mars, and the astronauts need too much supplies and necessary living facilities on the way.

In the end, Bill's team got inspiration from the "step plan".The solution they gave was: supply in batches!
First launch two to three supply pods to the reserved orbit. When the spacecraft departs, it only carries one-third of the fuel and supplies for the entire operation, and completes new supplies by docking with the supply pods on the way.

In this way, the spacecraft can be boldly accelerated. Bill's team calculated that according to the current maximum speed of the liquid propeller, it only takes three months and two days to reach Mars.

Bill called this supply method the "Mars Staircase Project"!
After hearing the news, all the scientists of the PDC breathed a sigh of relief. Just hearing this plan, they knew that it was very feasible.

The technology of liquid fuel aero-engine and space docking technology are very mature, and there are no technical difficulties, and the astronauts are familiar with the relevant operations.

As long as the spacecraft is assembled, it can start immediately.

Then everyone began to rejoice, fortunately, Moon City had already planned to land on Mars, otherwise it would be impossible to think of this way in a day or two, plus the construction of the spacecraft, etc., the time must be insufficient.

At the same time, some people think that all this is not too coincidental.
But it's just thinking about it this way. After all, it is difficult to connect the advanced intelligence signal of Mars with Jiang Yu, Bill, and Moon City.

You don't need to worry about the spacecraft, and then we have to solve the problem of astronauts landing on Mars.

Before planning to land on Mars, most people actually had no concept of interplanetary travel.

When the distance between the Earth and Mars was placed in front of everyone, everyone realized the arduous task of this task.

In everyone's previous concept, Mars seems to be very close to the earth, but this "very close" is also 9000 million kilometers away!
Even the perigee is about 6000 million kilometers away!
The circumference of the earth's equator is only 4 kilometers, and the distance between the earth and the moon is only 38 kilometers.

The trip to Mars this time is more than 200 times that of the farthest trip "moon landing" that humans have achieved so far!
That kind of feeling, like a child who has just learned to walk, is going to run a five-kilometer cross-country.

Then some people began to get a little excited, human beings were finally going to get out of their cradles.

……

To Jiang Yu's surprise, the PDC even invited him to participate in the selection meeting for the astronauts of the Mars spacecraft.

Originally, Jiang Yu thought that after the self-government of Moon City, the PDC would definitely let him sit on the bench for a while.

Unexpectedly, everyone still maintains the most basic respect for the Wallfacers.

Jiang Yu defeated the Wall Breaker before and cleaned up the mess for Taylor, so that the Wall Facing Project still has a lot of energy.

At least for now, everyone still values ​​this plan.

After all, who knows if Jiang Yu's actions are part of his plan?

In addition, as long as Jiang Yu does not cause substantial harm to the human world, and as long as he does not do anything like challenge the authority of the PDC, the PDC will not tear itself apart from the "true owner of Moon City" at this time.

Politicians like to "leave some room" for themselves. If they really want to deal with Jiang Yu, they have to wait until Jiang Yu is really useless.

As for the selection of astronauts, there is actually nothing to talk about, it is just a meeting of carve-up and compromise!
The crew of the Mars spacecraft is only six, and Moon City needs a spacecraft construction engineer to prevent the spacecraft from "broken down" halfway.

For the remaining five places, China, the United States and Russia each have one, Britain and France share one, and Germany and India share one.

Only in the "Qichang", the places have been divided up.

During the break of the meeting, the rotating chairman of the PDC asked Jiang Yu for a private talk.

Jiang Yu thought he was going to talk about the Moon City issue again, and he had already thought of a reason to shirk.

Unexpectedly, as soon as we met, the rotating chairman said: "All countries have checked and arrested some of the 'anti-escapeism' demonstrators with a strong attitude.

"After interrogation, most of them turned out to be ETO members!

"According to the clues they provided, the French police have just arrested an ETO executive whose game ID is 'Zhou Wenwang'."

　Thanks for the 1500 point reward from [Yixiaodianwuhen].
