These are the two most important questions in front of Chen Yue's eyes.

The importance of robots and equipment at the Mars base is self-evident. This is the foundation for Chen Yue's future plans.

It's like the start-up capital for a person who wants to start a business. There is no start-up capital, no matter how grand the business plan is, no matter how brilliant the business talent is, it is useless at all.

Mars must go, must go!

However, the fuel is not enough, and if you turn around and go to Mars in the middle, when the time comes, you don't even have the fuel to break free from the gravitational pull of Mars, and you can only be trapped in the orbit of Mars in the end.

Chen Yue thought quickly again.

"Huh? By the way, there are about 37 tons of metamethylhydrazine in the Mars base, and we have to find a way to get our hands on the fuel. But it's not easy...... What's more, even with these supplements, the fuel is still not enough. ”

Metamethylhydrazine is a high-performance rocket fuel that is now used as a propellant by the Glowing spacecraft.

Obtaining this fuel is the same as acquiring the robots and equipment on the Martian base.

The Glowing spacecraft could only stay in orbit around Mars, and could not land on the surface of Mars.

A starship is not the same as a landing spacecraft. There is no way for the Glowing spacecraft to land, and if it is forced to land, it will be like an airplane without landing gear, and crashing is almost the only outcome.

It is equipped with a landing module, which is usually used to travel to and from the surface of Mars and orbit around it.

In the original plan, Chen Yue also planned to stay in the orbit and remotely direct the robots and equipment on the surface to be built and produced according to his own plan.

Now, if you don't stay on Mars, you can only find a way to send those fuels, robots, equipment, and other things to space to meet with you.

However, if you only do this by remote control, you can imagine how difficult it is.

In particular, even if you do this, with the supplement of those metamethylhydrazine fuels, it is enough to break free from the gravitational pull of Mars, but it is still not enough to accelerate yourself to a sufficient speed.

At most, it can accelerate itself to about 10 kilometers per second. And at this speed, it will take about 4 years to get from Mars to Jupiter, including the time it takes to accelerate and decelerate.

Before that, it would take at least two years to get to Mars from where you are now. Add in at least half a year to Mars, for a total of six, a half to seven years.

And that piece of earth wreckage is about to hit the sun in five years......

It's too late.

Chen Yue's brain began to run wildly again.

After a long time, he sighed secretly.

With the help of the huge computing power of the central computer of the Glowing spacecraft, he found a plan that could theoretically take into account all aspects and had a certain feasibility and success rate.

Change course to Mercury, and then, with the help of Mercury's gravitational pull, use the gravitational slingshot effect to accelerate itself and change course to Venus.

In Venus, once again, the gravitational slingshot effect is used to "catapult" itself to Mars, and finally stay on Mars.

After that, get fuel, supplies, and equipment, break free from the gravitational pull of Mars, accelerate yourself, and travel to Jupiter, where you will finally be sheltered by Jupiter's magnetic field and avoid the influence of the raging solar wind.

If all goes well, the entire voyage will be completed within about 4 years and 11 months, and it will be safe from the influence of the solar wind.

It's an extremely complex route. The whole voyage involves many times of extremely high accuracy requirements, time requirements for extremely high course and speed adjustment, the slightest mistake, the whole route will be chaotic, no return.

And that's not even the hardest. The hardest part is that Mercury is too close to the Sun.

Mercury is less than 50 million kilometers away from the Sun at its closest point. Fifty million may seem like a lot, but it's still too close for a star as powerful as the Sun.

The solar radiation and electromagnetic interference there are extremely violent, and the Glowing spacecraft will be constantly scorched by the sun's heat, which may lead to equipment failure.

This is because the Glowing spacecraft was originally designed to land on Mars, which is relatively far from the Sun, not on Mercury. It doesn't have enough heat resistance.

But Mercury is an extremely important part of Chen Yue's entire plan, and it is impossible to avoid it.

"No matter, if you can't pass this level, you will die, and there is still a little hope to live if you pass it. The sword mountain and the sea of fire are also going to go away. ”

Chen Yue secretly gritted his teeth and made up his mind.

But even if the plan is so difficult, there is still a prerequisite for it to be implemented. Otherwise, Chen Yue would not even be qualified to carry out this plan.

That is, weight loss.

That's right, it's weight loss. Now Chen Yue's "body" is too "fat".

The Glowing Monster is a manned spacecraft. There is a large amount of equipment necessary for the survival of human beings. These devices occupy a large amount of mass. And the more mass there is, the more fuel is needed to propel it to accelerate or decelerate.

It's a pretty obvious thing.

Now, if you want to save fuel, you have to lose weight first.

Tear down the temporarily useless facilities and throw them away as a way to save fuel, speed up, and save time.

Chen Yue first made a comprehensive assessment of himself, made a table based on the importance of the equipment and the difficulty of demolition, and made a final decision in a few seconds.

Some of the equipment is no longer useful, such as kitchen tools. However, the galley is located in the center of the ship, and there is no way to dismantle it, so it can only be preserved.

After all, at this moment, Chen Yue could only use a few mechanical arms.

Some of the facilities located on the outside of the ship, such as isolation cells and passages, can be dismantled.

The isolation chamber is used when the astronauts are walking out of the capsule. But now that even the astronauts are gone, what else do you want to do, just dismantle it.

There are also astronaut cockpits, bathroom facilities, etc., all of which have been dismantled.

And, when judging the medical room, Chen Yue made a difficulty.

The medical room is a place where patients are treated, and there are some medical equipment and medicines in it. For the current Chen Yue, of course, it is useless and can be demolished.

But...... His own "corpse" is still inside.

This may be the only human corpse in the universe that is still intact......

In the future, when our technology is developed, we may be able to extract human DNA from it, clone new humans, and then rebuild the entire civilization.

If it is to be preserved, the medical room cannot be dismantled. Because at the moment, there are only a few robotic arms at his disposal, and there are no internal tools that can be used to move it out of the medical room.

If you want to throw it away, you must throw it away with your own body. To be retained, it must be kept along with the medical room.

According to estimates, the total mass of all the equipment in the entire medical room is about five tons.

Chen Yue sighed faintly.

"Let's take care of the present. If you can't even get through the difficulties in front of you, how can you talk about the future. Five-ton mass...... It's too fuel-intensive, and it's too much of a drag on me. ”

The inner hatch was closed, and outside, the robotic arm slammed down into the medical room.

It took about five hours for several robotic arms to smash the connection between the medical room and the hull without causing too much damage to the hull structure. With a slight push, the medical room containing his body inside slowly drifted away into the depths of the universe, gradually disappearing, and was never seen again.

Chen Yue knew that he had completely lost it.

Even if you develop technology in the future, you won't be able to find it back. Because according to the current orbit of the Glowing spacecraft, if it is not intervened, it will crash into the sun in about twenty years.

Before, Chen Yue was in a state of self-abandonment, even if he knew that he would crash into the sun, he did not interfere with the orbit of the Glowing Confusion spacecraft.

Now, the Glowing spacecraft is about to change its orbit and head in the direction of Mercury. The dismantled medical chamber and the rest of the space will still be in the same orbit as the Glow.

They can't escape the fate of crashing into the sun.

"Ugh."

With a light sigh, Chen Yue calmed down a trace of sadness in his heart.

It took him a total of five days to complete his weight loss.

A large number of unnecessary facilities were dismantled, so the total mass of the Glowing spacecraft at the moment was reduced from about 600 tons to 500 tons, a full one-sixth reduction.

If it weren't for the fact that some internal facilities were not easy to dismantle, he would have been able to reduce another 100 tons or so.

As a result, fuel consumption is significantly reduced.

Then, it's time to plan for the next step.

Chen Yue issued a command, and the engine of the spaceship, which had been silent for several months, immediately ignited, pushing it to start slowly accelerating in a certain direction.

The vastness of space, the vastness of the vastness. Except for the great and bright sun and the starry sky, everything else was pure darkness. Here, there is no up and down, no left and right, and no front and back.

No matter which direction you drive, it's like the same place. Whether you move or not, no matter how fast you move forward, it looks like you're stationary.

In space, far away from any star, without a reference, only the gravitational accelerometer could tell Chen Yue whether he was stationary or moving forward at the moment.

Of course, high-precision locators can also do this. It measures the relative position of several standard neutron stars to itself to achieve the purpose of pinpointing its own coordinates. But it consumes too much power, and Chen Yue has already turned it off at this moment.

The ship moved slowly, and in the blink of an eye, months passed.

After a long period of accumulation, it finally showed obvious results after a few months. At this moment, the remnant planet that split from the disintegration of the earth was much clearer and brighter in Chen Yue's vision. Even it is no longer a dot-like structure, but can be seen on the surface of the disk.

Looking at Mars with the naked eye on Earth is a point. Looking at the moon is a face. That's where distance comes in.

At this moment, Chen Yue is about 260,000 kilometers away from the wreckage planet.

This is the closest thing the two are in this vast space. After that, the two will pass by.

The Glowing spacecraft continues to Mercury, and the wreckage planet continues to run towards the Sun.

Looking at it from this closest distance, Chen Yue's heart was full of complicated thoughts.

At this moment, through the telescope, Chen Yue could clearly see that the wreckage planet was still dark red.

That means extremely high temperatures. Obviously, it hasn't completely cooled down at the moment.

The high temperature at the time of the disintegration and explosion, and the high temperature at the core of the original earth, will take a certain amount of time to cool down.

Chen Yue saw that the surface of this planet was full of vertical and horizontal magma, the ground was black and gray, with high mountains, canyons, and cracks, like hell.

There are also a large number of holes in the ground, and the holes are constantly spewing out magma or gas, like fountains.

These gases ejected from the inside are composed of nothing more than water vapor, carbon dioxide, carbon monoxide, nitrogen, oxygen, and so on.

These gases even form a thin atmosphere around the wreckage planet.

You know, such a small planet generally does not have an atmosphere. Because the denudation of the solar wind will ruthlessly blow the atmosphere away. Only a large planet like the Earth, which has a magnetic field and can withstand the solar wind, can retain its atmosphere.

But even so, the Earth's atmosphere continues to lose mass.

At this stage, it is nothing more than the internal gas of the wreckage planet is too abundant, and the amount of gas eruption is greater than the amount of loss, so that a thin layer of atmosphere will appear.

But this is unlikely to last long. When the gas inside it is finished, the atmosphere disappears.

But it shouldn't have to think about that much later. You know, it's going to hit the sun in a few years......

Skimming over the wreckage planet, the two drifted apart. It also became smaller and smaller in Chen Yue's field of vision, and eventually became a dotted star again.

And Chen Yue is getting closer and closer to Mercury.

The closer you are to Mercury, the closer you are to the Sun. As a result, Chen Yue clearly felt that the radiation encountered by the Luminous spacecraft was getting stronger and stronger, and the temperature was getting higher and higher.

In order to preserve his own facilities as much as possible and improve the survival rate, Chen Yue had no choice but to turn off most of the equipment. Even the computer I'm on has most of the functions turned off.

At this moment, the sun looks the size of a millstone, and it is extremely bright and dazzling. Even the surrounding sun can be clearly seen.

They are like hairs around the ball, fluttering and waving wildly, releasing an astonishing amount of energy.

Chen Yue only glanced at it and didn't dare to look at it again. If you look at it again, the telescope will be burned.

He just silently "curled" himself, silently endured the high temperature radiation and scorching, silently looking forward to the torture passing as soon as possible.

But soon, Chen Yue had to "wake up".

Because Mercury is already coming. If you want to use Mercury's gravity to accelerate yourself, you must adjust the Glowing spacecraft to the right course and speed, and you must also have the right attitude.

This meant that he had to activate some equipment to measure a few of the most critical parameters.
