Today's science and technology, you don't need to accelerate to how fast, and it won't take a few days to fly back to Earth, the star is speeding up very fast, it is installed with the maximum strength that Mars technology can support, and the two furnaces are called "energy furnaces", and two decomposition furnaces, people call these two furnaces "regeneration furnaces" - human beings are always vain, like to make up some inexplicable names to come out to bully others, such as the "birth committee", damn, isn't it the family planning office at this time? Fusion is fusion, decomposition is decomposition, why can't it be more straightforward?

Hydrogen, deuterium, and tritium are the basic energy sources of the Star, but these things often do not exist alone in interstellar space, and the two disintegration furnaces are used to do this, decomposing all the materials that can get these three things into the fuel that the Star can use, and they are doing a little mining work in the asteroid belt, and a little lithium is used as fuel. Theoretically, if there is no accident in the operation of the calciner, the Star can fly indefinitely in space, because the fuel it needs is inexhaustible in the universe. It can compress fusion energy into a tiny jet, allowing the spacecraft to gain velocity – a terrifying acceleration that has been kicked out of its original orbit forever by Martian scientists who have conducted fusion energy experiments on an asteroid and kicked an asteroid 100 kilometers in diameter out of its original orbit and into the outer solar system.

This force also acts on the spacecraft itself, although space flight is a less active science on Mars, people still invented a nano bodysuit, everyone on the spacecraft has such a set of nanorobots on the spine, its role is to counteract the reaction force when the spacecraft accelerates. The crew used this nanosuit to develop a ridiculous game, similar to bowling, where a group of people stood in a row trying to fix themselves, and one person stood in front of them when accelerating, and as soon as the ship accelerated, this person would hit the row of people like a cannonball, and the more people they knocked down, the more beautiful - the crew used this little game to gamble on working hours, on their bodies, on maternity points, etc., because government coins on Mars were meaningless and there were very few transactions, so the crew gambled on something of value that they could have.

This game is not harmful, but it once formed a kind of sociological problem: some crew members lost their working hours before they could go to work, and some people lost their bodies or reproductive rights - on Mars, space exploration is a non-mainstream job, and after serving on a spacecraft in any form of spacecraft for ten years, you can submit a fertility application to the Fertility Committee, and there are indeed people who serve on the spacecraft for this reason, and when he loses this, he has no incentive to continue to serve, so, There will be people sneaking around in some strange places - note that in today's solar system, Mars is the largest human settlement, the most prosperous, but not the last place where human beings live - losing the right to have sex on Mars does not mean that he has lost the right to survive and have children on Pluto, as long as this person can abduct a woman, he can actually fly to Pluto in a heavy spaceship and have a large number of children, as long as he can live.

The Martian government ignores this kind of slippery person, and it's useless to be too lazy to take care of you, as long as you don't come to Mars, and the rest as long as you have the ability, you can go to the sun to be born. In the view of Zhang Tianhe, who has been flying for many years, this is just human curiosity, in fact, sometimes the crew members don't know that he will lose the motivation to work on the spaceship after losing the maternity rights points, but he wants to do this, and see what impact he has on his short life that is not easy to find meaning - in fact, it has no effect, you can still go to work in Mercury Mining Company and continue to live, but when you get there, you still have to work for free to earn reproductive rights. And no matter how desperate you try, you can only be born on Mercury at best, and if you go back to Mars, you are an illegal immigrant, and you risk being launched into space beyond Saturn's orbit - in the popular phrase "cooled" - and the outer solar system is quite cold.

So when Zhang Tianhe was accelerating, he knew for sure that someone was playing this kind of boring game in the space under the spacecraft, but he didn't plan to ask, the solar system was too big, and people could still live without Mars and the stars, what was there to ask - as long as they didn't fight on the spaceship.

"Captain, do you want to fly by Mars?" Shi Kening asked him from the communicator at this time.

"Why?"

"Gravitational slingshot, you can save fuel, anyway, ......"

"Anyway, if you can do it, you're going to rub it off? Why take advantage of Mars? Who did you learn this kind of hand from you, can't you fly straight to the moon? ”

"Absolutely!" Shi Kening replied, and he was silent for a while, "Captain, do you need to chat?" ”

"Enough talk today, thank you for your kindness."

Shi Kening followed Zhang Tianhe all the way to do space travel to become the first mate, you know, there is no low-culture person like him in this position, so culture is a good thing at any time, and something is better than nothing. But Shi Kening is the person who knows Zhang Tianhe best, and when Mars was still promoting the Star Project, no second person knew that Zhang Tianhe had long been holding back an evil fire against the Martian government, only Shi Kening knew, and he was tight-lipped. Another point, Shi Kening's flight record is quite beautiful, and he has been involved in the Star Project since the design, if Zhang Tianhe is the person in the solar system who loves and knows the stars best, then Shi Kening may be the second, this kind of love has a contrast - the two of them have one thing in common is that they love the stars more than they love Mars, this meaning is very subtle, sometimes words can't express it - love can never be expressed exactly.

So in other words, Zhang Tianhe and Shi Kening have a similar position, if there is any major decision on the Star, Zhang Tianhe believes that Shi Kening and his decision will be similar, this kind of loyalty is irreplaceable, it is based on time and experience, so he tried his best to fight for Shi Kening for a first mate position, and to be honest, this position is far more technical than political, so it doesn't matter to the Martian government, for them, what is in Zhang Tianhe's mind is much more reliable than an outsider.

Shi Kening didn't know that Zhang Tianhe had this kind of thing in his mind to monitor emotions, this thing was installed before the flight, and Zhang Tianhe could only let them be safe at that time, otherwise, wouldn't the Star go to the sky? In the past, he had the habit of chatting with Zhang Tianhe, every night before the lights went out, whether they were flying or resting on Mars, whether they were talking about humans or the universe, whether they were together or on the communicator, they always had to talk for a while, but now Zhang Tianhe has changed this habit, and he has to change it - strangely, it seems that now he only has emotional ups and downs when he talks about something with Shi Kening, and he sometimes wonders if he is in love with this first mate. The long and boring space flight career made Zhang Tianhe gloomy and suspicious, and it seemed that he could only speak freely when communicating with Shi Kening, and now the Martian government has deprived him of this kind of fun.

But...... It doesn't seem to matter, Zhang Tianhe has flown many times as a captain, and this experience makes him feel as calm as water as soon as he sits in the position of captain, and no matter how the crew gambles, the Martian government entanglement, and Jenny Yang's weird theories can't bother him, let alone Shi Kening. They had already talked about their interests and views on the universe, there was nothing new to discover from each other's brains, and now it was only left to carry out the act of exploration and discovery, when the spacecraft accelerated and felt that weightlessness, the stars pulled the ground of the asteroid and took off towards a dark universe, Zhang Tianhe felt that a part of himself was flying behind him forever, and it was slowly retreating.

Maybe I don't need to study it, but I know why people lose their will if they are too fast...... He thought to himself as he looked at the orbiter. It's just that the body flies too fast and the brain can't keep up, I bet, if we can go faster, humans can just throw away all the souls, that is, just die?

He didn't want to go on anymore, it didn't mean much to him, about life and death, about the philosophical and theological explanations of human beings in the past, it had nothing to do with him, for him, these fantasy things were just like the selection criteria of the Fertility Committee, if people didn't want you to understand you, you would never understand, and you would be stupid to use your brain for it - if you don't let me be born, I won't give birth, I'll get a spaceship and fly out to give birth - so you have to find a way to overcome this system, not to ponder its standards......

But having said that, he just comforted himself like this, because after all, the planning of the stars plan was in the front and was rejected by the birth committee, and for him, as long as he could fly out, it was not impossible to be sterilized.

The Star quickly stabilized and flew towards the moon at a smooth speed. One of the nice things about Mars is that its day is about the same as that of Earth, so the biological clock of Martians is still about the same as it is on Earth. After the spaceship lifted off, Zhang Tianhe looked at the indicators, sent a signal to Shi Kening to turn off the lights, and then turned off the day holographic and entered a resting state. Many crew members have symptoms of mild holographic addiction, and the holographic communicator can simulate most of the scenes you want, so to speak, most of them rest with their beloved image every day, although it is only an image, but it is better than nothing - the intelligence of the Martian will slowly be seen by everyone. The Martians developed a real somatosensor, that is, you can not only see but also feel the various feelings in the hologram you want, but soon this device was monopolized by the government, and it is now used as a reward or medical device, and the holograms of the crew can only be seen but not touched. At the beginning, the Martian government wanted to install some phantom instruments for the Stars, but Zhang Tianhe decisively refused.

"Wouldn't it be nice to stay on Mars for the sake of comfort? You can have anything! He said it when he was arguing with Nick Ma about it.

"It can't be uncomfortable at all......

"Don't worry, no matter where you go, you will desperately look for a comfortable one that suits him, but it's just a matter of finding the problem that you can't find...... Somatosensory devices are not suitable for heaven, so you should keep them for your own use. ”

"You're sarcastic......" Nick Ma replied to him.
