Surprisingly, the planetary spacecraft in Moon City turned out to be a spacecraft powered by liquid fuel thrusters.

This can be seen by looking at the aero engine at the stern of the spacecraft.

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

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

Faced with the questions from engineers, the newly appointed lunar city mayor Burton claimed that the spacecraft could fly to Mars in three months!

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

Burton ignored these doubts and asked the PDC to first settle the scientific research budget for the next three years, and then announce the detailed Mars plan.

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

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

The representatives of the PDC countries have some toothache. The Declaration stipulates that the PDC needs to continue to provide scientific research funds to the Moon City, but for these old political players, it has never been said that they cannot be deducted or reduced year by year.

This is a detail that Jiang Yu and Bill had never thought of before. As the saying goes, "Burton, who specializes in his profession, discovered this loophole and designed this routine after taking office.

With the signing of this contract, the wishful thinking of various countries was overturned.

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

Give Moon City three years, will there be a chance to hold on to them in the future?

But now PDC has a request for Moon City, so he can only sign the contract first and talk about what happened in the future.

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

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

The speaker is Bill, who starts with the first plan.

The first thing Bill's group argued was the acceleration method used in the "Stair Plan", but they soon discovered that the space sails that dragged the spacecraft might be as big as one-third of the moon.

Moreover, because it is dragging, it is difficult to control. Whether the space sail can be successfully closed after approaching Mars is also a difficult problem.

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

When the hydrogen bomb behind the spacecraft explodes, the shock waves and radiation generated are absorbed by the metal plate at the rear of the spacecraft. The force absorbed by the metal plate is used as the driving force for the spacecraft to advance.

However, after careful calculations by the members of the project, they found that the speed of this method was too slow.

The shock waves generated by the explosion of the hydrogen bomb will scatter in space. Even if the metal plates at the stern of the spacecraft are of square kilometers, there is little thrust.

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

Besides, metal plates are difficult to install. After all, the diameter of the spacecraft is only a few meters, and the widest part is only thirty or forty meters. There is a metal plate with a diameter of several kilometers behind it, which looks like a thumbtack at first glance.

The key is that it is not practical, and it is better to use traditional liquid fuel rockets to speed faster.

So the problem returned to the starting point. The spacecraft needed too much fuel to go to Mars, astronauts needed too much supplies and necessary living facilities on the way.

In the end, Bill's group got inspiration from the "stair plan". The solution they gave was: replenishment in batches!

First, two to three supply tanks are fired onto the booked orbit. When the spacecraft sets off, it only carries one-third of the fuel and supplies for the entire operation, and completes new supplies through docking with the supply tank on the way.

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

Bill called this supply method the "Martian Ladder Plan"!

After hearing the news, all the scientists at PDC breathed a sigh of relief. Just by listening to this plan, they knew that the feasibility was very high.

The technology of liquid fuel aircraft engines and space docking technology are already very mature, and there are no technical difficulties, and the relevant operating astronauts are also familiar with it.

As long as the spacecraft is assembled, you can set off immediately.

Then everyone began to be glad that Lunar City had a plan to land on Mars, otherwise this would not be possible in a day or two. In addition to the construction of the spacecraft, etc., time would definitely not be enough.

At the same time, some people also think that all this is a bit coincidental?

But I just thought about it this way. After all, it is difficult to connect the advanced intelligence signals of Mars with Jiang Yu, Bill, and the Moon City.

The spacecraft doesn’t need to worry about it, and then we need to solve the problem of astronauts landing on Mars.

Before planning to land on Mars, most people actually had no idea about sailing between planets.

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

In everyone’s previous concept, Mars seems to be very close to the earth, but this “very close” is 90 million kilometers!

Even perigee is about 60 million kilometers!

The circumference of the Earth's equator is only 40,000 kilometers, and the distance between the Earth and the Moon is only 380,000 kilometers.

This time the itinerary to land on Mars is more than 200 times the farthest itinerary of the "Moon Landing" that humans have achieved!

That feeling is like thinking that the child who has just learned to walk is going to run a five-kilometer cross-country trip.

Then someone began to be a little excited, and humans were finally about to step out of their cradle.

...

What surprised Jiang Yu was that the PDC actually invited him to participate in the selection meeting of Mars spacecraft astronauts.

Originally, Jiang Yu thought that after the Moon City was autonomous, PDC would definitely have to let him sit on the bench for a while.

Unexpectedly, everyone still maintained the most basic respect for the wall-faced person.

Jiang Yu defeated the Wall-Breaking Man and cleaned up the mess for Taylor, so he still had a lot of energy to face the Wall-Breaking Plan.

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

After all, who knows whether Jiang Yu’s actions will be part of his plan?

In addition, as long as Jiang Yu did not cause substantial harm to the human world and did not do anything similar to challenging the authority of PDC, PDC would not break up with the "real master of Moon City" at this time.

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

There is actually nothing to talk about about the selection of astronauts, it is just a meeting of division and compromise!

There are only six crew members of the Mars spacecraft. Moon City has to go to a spacecraft construction engineer to prevent the spacecraft from "breaking up" halfway.

The remaining five places are one for China, the United States and Russia, one for Britain and France, and one for Germany and India.

Only in the "Seven Constant Virtues" will the quota be divided up.

During the break of the meeting, the rotating chairman of the PDC asked Jiang Yu to talk to him alone.

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

But when they met, the rotating chairman said: "All countries have reviewed and arrested some of the tough-minded 'anti-escape' demonstrators.

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