Universe dominance

Here at the Jiuquan Aerospace Command Center, Li Fu and Liu Shiying looked at the huge display and breathed a sigh of relief when they saw that the reverse deceleration plasma engine of the aerospace plane had been successfully installed.

Here in the command center, the two of them can naturally see a lot of pictures and information that will not be disclosed to the outside world. As the top aerospace scientists, the two of them are on call at any time. Once any emergency occurs, many top experts will naturally be needed. Scientists worked together to come up with a response plan.

Of course, almost all aspects of such a major matter have been carefully considered, and all possible situations and corresponding countermeasures have been thought out. Now the two of them have nothing to do.

"After the construction of the lunar base is completed, I must go to the moon for a walk. Haha, I didn't expect that I, Liu Shiying, would be able to see China's huge leaps in development in the space field."

Liu Shiying said to Li Fu with a smile.

"Old Liu, is your goal just to walk on the moon? Don't you want to go to Mars?"

Li Fu on the side smiled slightly. It was obvious that he was very optimistic about China's future development in the space field. It had just begun. Li Fu estimated that it would not take too long to go to the moon until the lunar base was fully developed. It should be open to the public by then, and lunar tourism will be very simple by then.

"Mars? It's too far away. I'm already old, so I'll leave it to you young people to worry about. Once the lunar base is built and you go to the moon for a walk, you won't have any regrets in this life."

Liu Shiying shook his head slightly. He didn't dare to imagine going to Mars, or to the moon, not to mention going to Mars. He just didn't expect that China's space technology was developing at such a rapid pace. Now it was about to land on the moon and establish a lunar base. In the future, it would be every There are space planes flying to and from the moon every week, and there will be opportunities for scientists like him to land on the moon in the future.

At this time in space, the "Houyi" aerospace plane, which had replaced its batteries, compressed air, and installed its reverse deceleration plasma engine, had slowly left the "Tiangong" space station.

The aerospace plane kept circling the earth's orbit. First, it tested the reverse deceleration plasma engine. It was perfect, without any problems. Everything went according to the established plan.

"Fly to the moon!"

As the orders from the ground command center were issued, the aerospace aircraft began to prepare for flying to the moon, constantly flying around the earth in space, flying faster and faster. With the help of the earth's gravity, the "Houyi" aerospace aircraft The aircraft acquired an initial speed of 20 kilometers per second. After finding its direction, it immediately left its original orbit and flew towards the moon.

On board the Houyi Space Shuttle, after aligning its direction and obtaining the consent of the space station and the ground command center, Nan Junpeng issued the order to continue accelerating!

Instantly, the tail fin behind the "Houyi" flashed faintly, and its speed continued to accelerate. In the universe, because there is no air friction, there is no resistance. The speed of the spacecraft can theoretically be increased infinitely, but According to Einstein's mass-energy formula.

The faster the speed, the greater the energy, so when the speed reaches a certain level, the energy required to continue to increase the speed will increase geometrically.

Therefore, after the "Houyi" space shuttle accelerated to a speed of 43 kilometers per second, it chose to shut down the engine and rely on inertia to fly to the moon. This speed was strictly calculated. On the one hand, it can ensure that it will not take too long to reach the moon. If it were to fly over the distance of more than 360,000 kilometers between the earth and the moon at this speed (when the moon is close to the earth), it would only take less than 3 hours.

But time cannot be calculated so simply. It takes time to accelerate, and even more time to decelerate. Therefore, the planned arrival time is 4 hours, which is to arrive at the lunar orbit around 15:00 on October 1, 2019.

At the same time, because deceleration also consumes a lot of energy, the speed of 43 kilometers per second is obtained after precise calculation to ensure that the flight time will not be too long and the energy consumed during deceleration and acceleration can be within the control range!

"Everyone, please have a good rest. The control center will wake you up at the right time!" Nan Junpeng, who shut down the engine, informed his teammates through the virtual machine to have a good rest. There is still the important task of landing on the moon waiting for everyone, and everyone must Stay in top shape to meet challenges.

"go to bed now!"

The nine astronauts gently pressed a button with a sleeping pattern next to their seats, and the seats automatically adjusted to the most suitable sleeping position. Of course, there is no weight at all in space, and everyone is drifting, so it is impossible to talk about it. That position is more comfortable and you can sleep however you want.

However, in order to allow astronauts to have a good sleep in space, this chair is specially designed and can be slightly curled to wrap the astronauts in it. Sleeping in it will give the astronauts the feeling of being in their mother's belly. I particularly like this invention and design.

Everyone else also knew that this was their rare rest time. Everyone took the time to rest, and soon all 9 people fell into a deep sleep. This is the skill that the best astronauts must develop, anytime and anywhere. Go to sleep and get enough rest to maintain high energy and peak performance.

The speed of the "Houyi" is very fast, but in the context of the entire universe and without any reference objects, it seems to be quietly suspended in space.

Here at the ground command and control center, the "Tiangong" space station located on the earth and the "Yuegong" space station located on the moon are constantly in contact with each other and the "Hou Yi" aerospace aircraft, constantly confirming the position of the "Hou Yi", super The computer continuously calculates the arrival time of the "Hou Yi".

"Wake up the astronauts!"

Soon the time came to 15:00, which was two hours after the "Hou Yi" aerospace plane set off. The people at the ground command center did not hesitate to choose to send instructions to the "Hou Yi" aerospace plane.

Soon, Nan Junpeng, Li Yang and other nine astronauts woke up from their sleep. At this time, looking back in the direction of the earth, the entire earth had become extremely bright. The sun's rays were reflected by the earth, making the earth look like Just like a huge full moon.

On the other hand, looking at the moon, the originally bright moon has become very huge, but now it looks bumpy and speckled, not at all as beautiful as it looks on the earth.

"We will reach the lunar orbit in 2 hours, start slowing down!"

The moon's gravity is obviously not as strong as the earth's, so the speed must be slowed down enough to be captured by the moon's gravity. The engine is restarted, especially the reverse plasma engine in the front starts to work, and the speed of "Houyi" begins to slow down. of reduction.

The places where a spacecraft really consumes energy when traveling in the universe are the initial acceleration and the deceleration when it is about to arrive. The energy consumed in these two stages accounts for more than 90% of the total energy consumption, because according to the mass-energy formula, whether it is deceleration or acceleration They all require a huge amount of energy, but relying on inertial flight in the middle basically consumes no energy.

Two hours later, the speed of the aerospace plane had dropped to only a few kilometers per second. The moon continued to magnify in the field of vision, and was already close to the ruler.

On the Earth side, through the high-definition camera carried on the "Houyi", people all over the world have seen very clear images of the moon. Compared with the moon landings of the past century, the high-definition cameras carried on this moon landing can capture The pictures are completely different, more high-definition and still in color.

"Get ready to enter lunar orbit!"

Whether it was the nine astronauts on the "Hou Yi" or the ground command center, everyone began to get nervous, because the most critical link had been reached. Although the speed of the "Hou Yi" had slowed down enough to be hit by the moon, The degree of gravitational capture, but you still need to be very careful. If you accidentally miss the moon, it will be very troublesome.

The "Houyi" aerospace plane slowly approached the moon at a very low speed, was captured by the moon's gravity very smoothly, and began to fly around the moon's orbit. At the same time, it began to continuously adjust its orbit and speed, preparing to face the moon." The Lunar Palace space station once again supplies energy and compressed air to prepare for the moon landing.

"Dear viewers, the Houyi aerospace plane has been successfully captured by the moon's gravity and has successfully passed the most dangerous moment. At this time, it is constantly adjusting its orbit and preparing to dock with the Yuegong Space Station, where it will conduct final energy and energy refueling operations. The supply of compressed air will be carried out once the supply is completed. "

At this time, on the Chinese side of the earth, almost all TV stations are live broadcasting China's manned moon landing activities. Naturally, some experts and scholars in the aerospace field are invited to interpret on the spot, and they can explain every step and every link. One, two or three, it can be regarded as a popular science education for the entire Chinese people.

On the side of the moon, the "Houyi" aerospace plane flew slowly, getting closer and closer to the "Yuegong" space station, and finally docked slowly and smoothly. The energy capsule and compressed air capsule on the aerospace plane slowly Opened, the robotic arm on the "Moon Palace" space station began to replace new energy batteries and compressed air.

On the other side, several astronauts on the "Houyi" aerospace plane began to enter the "Yue Palace" space station, and completed some things inside that could not be completed by machines and required astronauts to complete. This will pave the way for the "Yue Palace" space station to serve as a space station between the earth and the moon in the future. Prepare for the transit space station.

According to the plan, the "Moon Palace" space station will be stationed for a long time in the future and will become an existence similar to the "Tiangong".
