Like other large aircrafts, the Zheng He still flies around the earth a few times, relying on the earth's gravity to obtain a faster initial velocity, which can greatly reduce the fuel consumption for acceleration.

The initial speed of 20 kilometers per second, according to Einstein's mass-energy conversion formula, coupled with the huge mass of the Zheng He, an astronomical huge energy demand can be obtained, and the gravitational force of the massive celestial body can be used to fly, This is a lesson that space navigation must learn.

Zheng He relied on the earth to obtain a good initial velocity, identified the direction of Mars, and the powerful nuclear fusion engine began to start. Relying on the temperature of more than 100 million degrees, it directly vaporized and ionized the air, producing an unparalleled driving force.

Even the Zheng He has a very large mass, but with such a powerful power, the speed also accelerated rapidly, and it didn't take long for it to reach a speed of 100 kilometers per second, and the speed is still increasing. , after all, this voyage is really too far, it is the longest voyage in human history!

The first station of Zheng He is Mars. The distance between Mars and the earth is about 55 million kilometers at short distance, and the farthest distance is more than 400 million kilometers. The close contact between the two occurs about every 15 years. once. The last time the two planets came together was in 2008, and the distance between the two was 57.6 million kilometers.

Obviously, the distance between Mars and Earth at this time is not the closest distance. The distance between Mars and Earth at this time is about 100 million kilometers, such a long distance, even at a speed of 100 kilometers per second. Flying for nearly 300 hours, more than 12 days, if you count the time spent on acceleration and deceleration, it will be even longer!

An hour later, the Zheng He hurried past the moon without stopping. The deceleration consumes more energy than the acceleration. The acceleration can rely on the earth's gravity, and there is no way to decelerate.

Report to the captain, everything is running normally!

Li Jun nodded, and then checked all the data in person. The communication is normal, the quantum pass technology is still very good, the power system has been turned off, the speed has reached more than 100 kilometers per second, and the energy consumed by accelerating it will increase exponentially. , very uneconomical, it is better to rely on inertia to fly down.

After checking the systems one by one, the state is very perfect. It is not a scientific expedition ship built by spending a huge amount of money and many scientists in the research institute. This Zheng He can be said to be the most peak spacecraft of human beings at present. The crystallization of science and technology.

Everyone, take turns to rest! Always pay attention to meteorites and meteors in the void! Let me know as soon as anything happens!

The long journey is very boring. There is nothing in the void, except for the inconspicuous meteorite that occasionally passes by. Under the gravitational force of the fireballs, they are running on a trajectory of billions of years, but their outlines are getting smaller and smaller.

After Li Jun finished his instructions, he returned to his room. The Zheng He was very large, but it only carried 1,000 people. Each person had a relatively good small space, 3 meters long, 4 meters wide, and 2 meters wide. It is high and close to the edge of the spaceship, so you can watch the scenery outside at any time.

According to the usual practice, Li Jun first made a video call with his wife. The long and boring journey is a torment for people's hearts. Only contact with family members can comfort them.

The phone call for more than an hour made Li Jun smile. Dong Qian had a good life under the care of both parents. Her son was very obedient. Beside him, he was quite different from his usual mischievous personality, which made Li Jun look up to him with admiration.

After turning off the communicator, Li Jun sat cross-legged and began to practice Yuanli. This is also a good way to polish the time. When immersed in Yuanli practice,

You can't feel the loss of time at all.

Regarding the cultivation of Yuan Li, this is a matter that the whole company attaches great importance to, especially on the Zheng He, all people are forced to cultivate for more than 2 hours a day.

Because the Zheng He has to travel in the void for a long time, it will cause bone loss in people without the influence of gravity for a long time. If you don't exercise every day, the lost bone will never come back over time. , at that time it was over, and it would be very difficult for people to even walk when they returned to the ground, and in severe cases they would even be paralyzed.

Therefore, the international solution to this kind of problem is to let astronauts wear a belt or the like to perform physical exercise for at least 2 hours a day in space, so as to maintain the bone in the bone and only when they return to the ground. normal activities.

For the attention of employees, Qingquan Technology is naturally equipped with sports equipment, but the effect of this kind of transportation equipment is far less than that of Yuanli training, so all people are forced to do 2 hours of training, which is a benefit to their own bodies. Of course, no one would object to the love and care of Yuan Li, not to mention that Yuan Li's cultivation makes people more energetic and full of energy.

After cultivating Yuan Li, Li Jun came out to the control center again to check and inquire about the situation of the spacecraft. There were no problems, and Li Jun went to eat with confidence.

If there is anything in space that is more painful than loneliness, then it must be a meal. All foods are nutritionally balanced and easy to store for a long time. As for the taste, it is not what they consider at all.

At this time, Li Jun was in the agricultural area. He was holding a book Physics of the Universe in his left hand and a toothpaste-like thing in his right hand. He kept squeezing out some toothpaste-like things and eating them!

As for the taste, it can only be said to be average. It is different from the Moon Base or Chang'an Space City. There is no supply here. Everything can be saved as much as possible. In terms of food, it is not bad to be able to do this now.

A piece of toothpaste-like food is the amount of Li Jun's meal. Although the taste is average and the amount is not large, it contains a lot of nutrients, enough to ensure the human body's needs for all substances.

The crops in the agricultural area exude an unknown atmosphere. Staying here is very reassuring. Many people like to come here to sleep quietly or read a book!

Day after day, time is slowly running away, the outline of the earth is getting smaller and smaller, and a fiery red disk is getting bigger and clearer.

After more than ten days of voyage, the Zheng He scientific research vessel is finally about to arrive at its first stop, Mars!

PS: Happy weekend everyone~~ (To be continued.)
