Chapter 131, Landing on the Moon
At the Jiuquan Aerospace Command Center, Li Fu and Liu Shiying looked at the huge monitor, seeing that the reverse deceleration plasma engine of the aerospace plane had been installed very smoothly, and they were also slightly relieved.

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, and as the top aerospace scientists, the two are also on standby at any time. Once any emergency occurs, they will naturally need many top experts Scientists negotiate together to come up with a response plan.

Of course, for such an important matter, almost all aspects have been carefully considered. All possible situations and corresponding countermeasures have already been thought out, and now the two of them can be regarded as idle and have nothing to do.

"After the construction of the lunar base is completed, I must go to the moon once, haha, I never thought that I, Liu Shiying, would be able to see the great leap forward development of China in the space field."

Liu Shiying said to Li Fu with a smile.

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

Li Fu on the side smiled slightly. Obviously, he is very optimistic about China's future development in the space field. It has only just begun. Li Fu does not think it will take too long to go to the moon to play, until the moon base is complete enough. At that time, it should be open to the public, and lunar tourism will also be very simple.

"Mars? It's too far away. I'm already old, so I'll leave it to you young people to make troubles. When the moon base is built and you go to the moon, you will have no regrets in this life."

Liu Shiying shook his head slightly, not to mention going to Mars, even the moon. He didn't dare to imagine it before, but he didn't expect that China's space technology is developing so fast. Now it will land on the moon and establish a lunar base. There are space planes going to and from the moon every week, and there will be opportunities for scientists like him to go to the moon in the future.

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

The aerospace plane is constantly orbiting the earth. First, the reverse deceleration plasma engine was tested. It was perfect, without any problems, and everything went according to the established plan.

"Fly to the moon!"

With the order from the ground command center here, the aerospace plane began to prepare for the flight to the moon, continuously flying around the earth in space, and the flying speed became faster and faster. With the help of the gravity of the earth, the "Houyi" aerospace plane The plane gained an initial speed of 20 kilometers per second, and after confirming its direction, it left its original orbit and flew towards the moon.

On the Houyi space shuttle, after aligning the direction and getting the consent of the space station and the ground command center, Nan Junpeng gave the order to continue to accelerate!

In an instant, the tail fin behind the "Hou Yi" flickered and fluctuated, and its speed continued to increase. In space, 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 increasing the speed will increase geometrically.

Therefore, after the "Houyi" space shuttle accelerated to a speed of 43 kilometers per second, it chose to turn off the engine and fly to the moon by inertia. This speed is strictly calculated. On the one hand, it can ensure that the time to reach the moon will not be too long. If you only fly over the distance of more than 36 kilometers between the earth and the moon at this speed (the moon is close to the earth at this time), it will take less than 3 hours.

But the 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, that is, it will reach the lunar orbit at around 2019:10 on October 1, 15.

At the same time, because the 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 also be controlled within the control range!
"Everyone, take a good rest. The control center will wake you up at the right time!" Nan Junpeng, who turned off the engine, notified his teammates to take a good rest through the virtual machine. There is still a mission to land on the moon waiting for everyone. Stay in perfect condition to meet the challenge.

"go to bed now!"

Nine astronauts lightly 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 people are all floating. That position is more comfortable, and I can sleep however I want.

However, in order to allow astronauts to have a good sleep in space, this chair is specially designed to be slightly curled, wrapping the astronauts in it, and sleeping in it has a feeling of being in the belly of a mother. Astronauts I really like the design of this invention.

Everyone else knew that this was their rare time to rest, and everyone seized the time to rest, and soon 9 of them fell into a deep sleep. This is the skill that the best astronauts must practice, anytime, anywhere Go to sleep and get enough rest to maintain vigorous energy and peak state.

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

Here in the ground command and control center, the "Tiangong" space station located on the earth and the "Yuegong" space station located on the moon keep in touch with each other and constantly confirm the location of the "Houyi", super The computer constantly calculates the arrival time of the "Houyi".

"Wake up the astronauts!"

Soon the time came to 15 o'clock, that is, two hours after the departure of the "Houyi" aerospace plane, the ground command center here chose to send instructions to the "Houyi" aerospace plane without hesitation.

Soon, Nan Junpeng, Li Yang and other nine astronauts woke up from their sleep. Looking back at the direction of the earth, the whole earth has become extremely bright. The light of the sun is reflected by the earth, making the earth look However, it is like a huge full moon.

On the other hand, on the side of the moon, the original bright moon has become very huge, but now it looks bumpy and spotted, not as good-looking as it looks on the earth.

"It will reach the moon orbit in 2 hours, start to slow down!"

The gravitational force of the moon is obviously not as strong as that of the earth, so the speed must be reduced enough to be captured by the gravitational force of the moon. The engine is restarted, especially the front reverse plasma engine starts to work, and the speed of "Houyi" starts to slow down. decrease.

The place where the spacecraft really consumes energy when navigating in the universe is 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 Both require huge energy, but relying on inertial flight in the middle basically consumes no energy.

Two hours later, the speed of the aerospace plane has been reduced to only a few kilometers per second, and the moon is constantly zooming in in the field of vision, and it is 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 pictures of the moon. Compared with the moon landing in the last century, the high-definition camera carried on this moon landing can capture The pictures are completely different, more high-definition, or in color.

"Ready to enter lunar orbit!"

Whether it is the nine astronauts on the "Houyi" or the ground command center, everyone is starting to get nervous, because the most critical link has been reached, although the speed of the "Houyi" has slowed down enough to be captured by the moon. The degree of gravitational capture still needs to be very careful, and it will be very troublesome to accidentally pass by the moon.

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

"Friends from the audience, the Houyi aerospace plane has been successfully captured by the moon's gravity and passed the most dangerous moment smoothly. At this time, it is constantly adjusting its orbit and preparing to dock with the Moon Palace Space Station. Compressed air resupply, and once resupply is complete the lunar landing will take place."

At this time, almost all TV stations on China's side of the earth are broadcasting China's manned moon landing activities live. Naturally, it is necessary to invite some experts and scholars in the field of aerospace to interpret on the spot, and every step and every link can also be said. One, two, three, it can be regarded as a popular science education for the whole of China.

On the side of the moon, the "Houyi" aerospace plane flew slowly, getting closer and closer to the "Moon Palace" space station, and finally docked very smoothly. The energy cabin and compressed air cabin on the aerospace plane slowly Open, the mechanical arm on the "Moon Palace" space station began to replace the new energy battery and compressed air.

On the other side, several astronauts on the "Houyi" aerospace plane began to enter the "Moon Palace" space station, where they completed some things that could not be done by machinery and could only be done by astronauts. Prepare for the transit space station in between.

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