Here in the Jiuquan Aerospace Command Center, Li Fu and Liu Shiying looked at the huge display and saw that the reverse deceleration plasma engine of the aerospace aircraft was installed very smoothly, and the two of them were also lightly 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 public, and as the top aerospace scientists, the two are also on standby at any time, once there is any emergency, it is natural that many top scientists need to negotiate together to come up with a response plan.

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

"After the construction of the moon base is completed, I must go to the moon once, haha, I didn't expect that I, Liu Shiying, would be able to see the huge leap forward development of our China in the field of space."

Liu Shiying said to Li Fu with a smile.

"Lao Liu, is your goal just to go to the moon once? Don't you want to go to Mars to see it? ”

Li Fu on the side smiled slightly, obviously very optimistic about the future development of Huaxia in the field of space, it has just begun, and it will not take too long to go to the moon to play, and when the moon base is perfect enough, it should be open to the people, and then lunar tourism is also a very simple thing.

"Mars? It's too far, I'm already old, so I'll leave it to you young people to toss, and when the moon base is built, go to the moon for a walk, and there will be 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 Huaxia's space science and technology would develop so rapidly, and now he is about to land on the moon and establish a lunar base, and in the future, there will be an aerospace plane to and from the moon every week, and there will be a chance for scientists like him to land on the moon in the future.

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

The space plane continued to orbit around the earth, first testing the reverse deceleration plasma engine, which was perfect, without any problems, and everything went according to the established plan.

"Fly to the moon!"

With the help of the earth's gravitational pull, the "Houyi" aerospace plane obtained an initial velocity of 20 kilometers per second, and after identifying the direction, it flew directly out of its original orbit towards the moon.

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

In an instant, the tail behind the "Houyi" faintly flashed and fluctuated, and its speed continued to accelerate, in the universe, because there is no air friction, there is no resistance, and the speed of the spacecraft can theoretically be added 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 exponentially.

Therefore, the "Houyi" space shuttle accelerated to a speed of 43 kilometers per second and then chose to turn off the engine and fly to the moon by inertia, such a speed is strictly calculated, on the one hand, it can ensure that the time to reach the moon will not be too long, if it only flies at this speed over the distance of more than 360,000 kilometers between the earth and the moon (at this time the moon is close to the earth), it only takes less than 3 hours.

But time can't be so simple to calculate, this acceleration takes time, deceleration takes time, so the arrival time planned by Qingquan Technology is 4 hours, that is, about 15 o'clock on October 1, 2019 to reach the lunar orbit.

At the same time, because deceleration is also very energy-consuming, the speed of 43 kilometers per second is accurately calculated to ensure that the flight time is not too long, and the energy consumed when decelerating and accelerating is within the control range!

"Rest well, the control center will wake everyone up at the right time!" Nan Junpeng, who turned off the engine, informed his teammates through the virtual machine to have a good rest, and there was still the heavy task of landing on the moon waiting for everyone, and everyone must maintain the most perfect condition to meet the challenge.

"Sleep!"

Nine astronauts gently pressed a button of the sleep 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, people are fluttering, not to mention that the position is more comfortable, how to sleep as you want.

However, in order to allow astronauts to have a good sleep in space, this chair is specially designed to be slightly curved to wrap the astronauts in it, and sleeping in it has a feeling of being in the mother's belly, and the astronauts especially like this invention design.

Everyone else also knows that this time is their rare rest time, all of them seize the time to rest, and soon 9 people fall into a deep sleep, this is the best astronaut must practice the skill, anytime, anywhere into a state of sleep, full rest, so as to maintain vigorous energy and peak state.

The speed of the "Houyi" is very fast, but in the context of the entire universe, and without any reference materials, it is as if it is quietly suspended in space.

The ground command and control center here, the "Tiangong" space station on the earth and the "Yuegong" space station on the moon are constantly in contact with each other and the "Houyi" aerospace aircraft, constantly confirming the location of the "Houyi", and the supercomputer is constantly calculating 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, and the ground command center did not hesitate to choose to launch instructions to the "Houyi" aerospace plane.

Soon, nine astronauts including Nan Junpeng and Li Yang woke up from their sleep, and when they looked back at the direction of the earth, the whole earth had become extremely bright, and the sun's light reflected through the earth, making the earth look like a huge full moon.

On the other hand, on the side of the moon, the originally bright moon has become very huge, but at this time it looks bumpy and speckled, and it is not as beautiful as it looks on the earth.

"There are still 2 hours to reach the orbit of the moon and start slowing down!"

The gravitational pull of the Moon is obviously not as strong as that of the Earth, so the speed must be reduced to the extent that it is captured by the gravitational pull of the Moon, the engine is restarted, especially the reverse plasma engine in front of it begins to work, and the speed of the "Houyi" begins to slowly decrease.

The real energy consumption of spacecraft in the space is the initial acceleration and deceleration when it is about to arrive, and the energy consumed in these two stages accounts for more than 90% of the total energy consumption, because according to the mass-energy formula, both deceleration and acceleration require huge energy, but the middle relies on inertial flight basically does not consume energy.

Two hours later, the speed of the spaceplane had been reduced to just a few kilometers per second, and the moon was zooming in on the horizon to a ruler.

On this side of the earth, through the high-definition camera carried on the "Houyi", people all over the world have seen a very clear picture of the moon, compared with the moon landing in the last century, the high-definition camera carried by the moon landing can take pictures completely different, more high-definition, or color.

"Prepare to enter lunar orbit!"

Whether it is the nine astronauts on the "Houyi" or the ground command center, all of them are starting to get nervous, because they have reached the most critical link, although the speed of the "Houyi" has been reduced to the extent that it is enough to be captured by the moon's gravity, but it still needs to be very careful, and it is very troublesome to accidentally pass by the moon.

The "Houyi" aerospace aircraft slowly approached the moon at a very low speed, was captured by the moon's gravity very smoothly, and began to fly around the lunar orbit, and at the same time began to constantly adjust the orbit and speed, preparing for the "Moon Palace" space station on the lunar side, once again replenishing energy and compressed air to prepare for the moon landing.

"Audience friends, the Houyi space plane has been successfully captured by the moon's gravity, and successfully passed the most dangerous moment, at this time it is constantly adjusting its orbit, preparing to dock with the Moon Palace space station, and carry out the final energy and compressed air supply at the Moon Palace space station, and once the supply is completed, it will land on the moon."

At this time, on the Chinese side of the earth, almost all TV stations are broadcasting the manned lunar landing activities in China throughout the whole process, and it is naturally indispensable to invite some experts and scholars in the field of aerospace to interpret on the spot.

On the moon side, the "Houyi" aerospace aircraft flew slowly, getting closer and closer to the "Moon Palace" space station, and finally docked very smoothly, the energy capsule and compressed air cabin on the aerospace plane slowly opened, and the mechanical arm on the "Moon Palace" space station began to replace with new energy batteries and compressed air.

On the other hand, several astronauts on board the "Houyi" aerospace plane began to enter the "Moon Palace" space station, completing some things that cannot be done mechanically and that require astronauts to complete, in preparation for the "Moon Palace" space station to be used as a transit space station between the Earth and the Moon in the future.

According to the plan, the "Moon Palace" space station will also be manned for a long time in the future, becoming an existence similar to that of the "Tiangong".
