A genius remembers "Love to go ÷ small? Speak → Net" in one second to provide you with wonderful novel reading.
"Zhenghe", like other large aircraft, still first orbits the earth a few times, relying on the gravity of the earth to obtain a faster initial speed, which can greatly reduce the fuel consumed by acceleration.
The initial speed of 20 kilometers per second, according to Einstein's mass-energy conversion formula, plus the huge mass of the "Zhenghe", we can obtain astronomical huge energy requirements, and use the gravity of large-mass celestial bodies to fly. This is a course that space navigation must learn.
"Zhenghe" relied on the earth to obtain a good initial velocity, and identified the direction of Mars. The powerful nuclear fusion engine began to start, relying on temperatures exceeding hundreds of millions of degrees to directly ionize the air into gas, producing an unparalleled driving force.
Even though the quality of the "Zhenghe" is very large, under such a powerful power, the speed has also accelerated rapidly, and it has not reached long enough to reach a speed of 100 kilometers per second, and the speed is constantly increasing. After all, this voyage is really too far, the farthest voyage in human history!
The first station of the "Zhenghe" was Mars. The distance between Mars and Earth was close to 55 million kilometers, and the longest distance was more than 400 million kilometers. Close contact between the two occurred approximately every 15 years. once. The two planets were last close in 2008, with a distance of 57.6 million kilometers between them.
Obviously, the distance between Mars and Earth at this time is not the shortest 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 take into account the acceleration and deceleration time, it will be even longer!
An hour later, "Zheng He" and the Moon hurriedly passed by without stopping. The energy consumed for deceleration was greater than the acceleration. The acceleration can rely on the gravity of the earth. There is no way to decelerate.
"Report to the captain, everything is working!"
Li Jun nodded, and then personally checked all the data again. The communication was normal. The quantum pass technology is still very powerful. The power system has been shut down and the speed has reached more than 100 kilometers per second. The energy consumed for further acceleration will increase geometrically. It is very uneconomical, and it is better to fly down by inertia.
The system was checked one by one, and the state was perfect. It was not a scientific research ship costing a lot of money and the efforts of many scientists in the research institute. This "Zhenghe" can be said to be the highest human spacecraft at present. The crystallization of science and technology.
"Let's take turns to rest! Pay attention to the meteorites and meteors in the void at all times! Notify me of any circumstances!"
The long journey is very boring, there is nothing in the void, except for the inconspicuous meteorites that pass by occasionally, it is really a void. The bright earth in the distance with its little friends is still huge in the distance. Under the gravitational force of fireballs, they follow the trajectory of billions of years, but their outlines are getting smaller and smaller.
After Li Jun ordered it, he returned to his room. The "Zhenghe" was very large, but only carried 1,000 people. Each person had a relatively good small space, 3 meters long, 4 meters wide, and 2 meters. It's high and close to the edge of the spacecraft, so you can see the scenery at any time.
According to the usual practice, Li Jun first had a video call with his wife. The long and boring journey was a torment for people's hearts, and only the contact with their family members could soothe.
More than an hour of talking, Li Jun couldn't help but smile. Dong Qian had been very good under the care of both parents. The son was very obedient. He always remembered that he had to help his father take care of his mother and his baby. By his side, the usual mischievous personality was very different, which made Li Jun's eye-catching look.
After closing the communicator, Li Jun sat down on his knees and started Yuanli practice. This is also a good way to polish time. When immersed in Yuanli practice, he can't feel the loss of time at all.
For the cultivation of Yuanli, this is something that the whole company attaches great importance to, especially on the "Zheng He". All people are compulsorily required to practice for more than 2 hours a day.
Because "Zhenghe" travels in the void for a long time, it will lead to bone loss for a long time without the influence of gravity. If you don't exercise every day, the lost bone will never return for a long time. At that time, it was already over. People would be very difficult to walk back to the ground, even severely paralyzed.
So the international solution to this kind of problem is to let astronauts strap things like belts for at least 2 hours of physical exercise every day in space, so as to keep the bone in the bones and return to the ground only Can be 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 cultivation, so all people are forced to perform 2 hours of cultivation. This is for their own bodies. Naturally, no one will object, not to mention that the cultivation of the power of the people is full of spirit and full of state.
After practicing Yuanli, Li Jun came back to the control center to check and inquire about the conditions of the spacecraft. Without any problems, Li Jun went to rest assured.
If there is something in the space that is more painful than loneliness, then it must be a meal. All foods are first of all about nutritional balance and easy to store for a long time. As for the taste is not what they consider.
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.
As for the taste, it can only be said to be ordinary. Unlike the Moon Base or Changan Space City, there is no supply here, everything can be saved, and it can be done in food.
A toothpaste-like food is the amount of Li Jun's meal. Although the taste is average and the amount is not large, the nutrition contained in it is not less than enough to ensure the human body's demand for all substances.
The crops in the agricultural area emit an unknown atmosphere. Staying here is very reassuring. Many people like to sleep here quietly or read a book!
Time goes by day by day, the outline of the earth is getting smaller and smaller, and a fiery red disk is getting bigger and bigger and clearer.
After more than ten days of sailing, the scientific research ship "Zhenghe" finally reached its first stop, Mars!
