Chapter 553 Heroes Return
at last!

Time always flies by, and it was time for the five astronauts to leave the surface of the moon. The five astronauts saluted the tightly placed bright five-star red flag. This bright five-star red flag and the The initially completed scientific research station represents the evidence that the Chinese people came to the moon. This is the ironclad proof that the Chinese manned landing on the moon has been successful, and no one can doubt it!
The gate of the scientific research station has long been closed, waiting for Chinese astronauts to visit this scientific research station again next time and open the door!
The five astronauts returned to the lunar module through the gangway one by one, and then the gangway retracted, and Liu Yang pressed the button to close the door of the lunar module.

"Report to the commander, the ground command center, and the five of us have returned to the lunar module. The door of the lunar module has been closed. After inspection, the lunar module is normal, and no abnormalities are found. It can be started at any time!" Liu Yang inspected the lunar module. Finally, report to the command module and the ground center at the same time!
"Agree to start!"

"Agree to start!"

Nie Haisheng in the command cabin and the command center on the ground both issued orders of agreement.

"5!"

"4!"

"3!"

"2!"

"1"

"0!"

"ignition!"

As the ignition command was issued, flames were seen shooting out from the nozzle of the lunar module!
This time, it was the engine of the lunar module that ignited!
Because the moon's gravity is much smaller than that of the earth, only about one-sixth of the earth's, the power from the engine easily pushed the lunar module into the sky, and easily got rid of the shackles of the moon's gravity and returned to the lunar orbit.

Then the lunar module and the command module changed orbits at the same time, and then at the set orbit and the set location, the lunar module and the command module flew in parallel in the same direction for a period of time, then slowly approached, approached, and then Closer, and finally the docking is done.

".This is the 'Chang'e' spacecraft. The lunar module has been successfully docked. Please give me instructions on the next step!"

At the ground command center, the commander-in-chief of the manned lunar landing looked solemn, and immediately ordered: "This is the ground command center. After hearing the order, abandon the lunar module!"

"Roger that!"

After receiving the order from the ground command center, the operation was carried out, and the lunar module was abandoned, and the astronauts, equipment, and materials inside had already been transferred to the command module.For the current "Chang'e" spacecraft, returning to the earth safely is the top priority. Although the lunar module is important, it is not the time to bring it back to the earth. Maybe the technology will go further in the future, and there will be greater confidence. It is possible to return to Earth with the lunar module.

And now, ditching the lunar module is the best choice!

Of course, the lunar module is not abandoned at will. In fact, there are pre-set programs on the lunar module. After being abandoned, the lunar module will orbit the corresponding orbit and act as a satellite.

This can be regarded as taking advantage of it as much as possible!

"This is the 'Chang'e' spacecraft, the lunar module has been abandoned, request for instructions on the next step!" The 'Chang'e' spacecraft sent back a message.

"This is the ground command center. After 20 minutes, turn on the fire and return!" The ground command center issued an order.

The command module does not mean that the lunar module can be ignited and returned at any time by abandoning the lunar module. Instead, it needs to follow the corresponding procedures and return at the most suitable time. Qin Yuanqing has already calculated all these. The ground command center, monitoring center, and space The quantum communication satellites, navigation satellites, and monitoring satellites of the station also feed back the situation of the command module back to the ground command center at any time.

In the entire ground command center, every engineer showed awe, because the next step is the last step of the manned moon landing project, returning from the moon to the earth!
Only by returning to the earth safely can the manned mission to the moon be truly a complete success!

If this step fails, then I'm sorry, the manned mission to the moon is only half the success, in the final analysis it is a failure, it is a huge aerospace disaster!

As the time came to the stipulated time, after the 'Chang'e' spacecraft received the order from the ground command center, the engine began to emit sparks, pushing the 'Chang'e' spacecraft to accelerate, constantly changing orbit, and then the speed quickly reached 2.4 The moon's escape velocity of kilometers per second successfully cut into the planned earth-moon transfer orbit.

After entering the Earth-Moon transfer orbit, the plasma engine began to emit sparks continuously, accelerating the "Chang'e" spacecraft. Although the acceleration per second is very low, it cannot withstand a long time, and the acceleration given is very objective!
In the middle and second half of the earth-moon migration orbit, the plasma engine began to perform reverse injection, but it slowed down.

One of the tasks of the manned moon landing project this time is to carry out the practical application of the plasma engine. Although the experiments were carried out in the previous three times, it was not actually applied to manned after all.This time it is a practical application, so as to provide data support for the next improvement and optimization of the plasma engine.

Compared with going from the earth to the moon, it took only two days to return from the moon to the earth this time, and it entered the earth's orbit, which saved one day compared to the previous time!
After reaching the earth orbit, the "Chang'e" spacecraft did not immediately enter the atmosphere, but orbited the earth in a geosynchronous orbit, and after orbiting the earth once, when it was not far from the "Tiangong" space station, the "Chang'e" 'The service module of the spaceship began to separate, and the service module was slowly approaching the 'Tiangong' space station, constantly approaching, and then slowly completed the docking.

The supplies in the service module, as well as the equipment that can be used, will be left to the 'Tiangong' space station!It is also possible to further expand the space of the 'Tiangong' space station, and one more astronaut can enter the 'Tiangong' space station in the future!

If it were the United States, they would definitely choose to abandon the service cabin.But Huaxia is different. Huaxia used to live in poverty before, sewing for three years and three years for sewing and repairing for another three years. Although now there are more funds and more money, they will not throw away what can be used easily, but try their best. use.

After separating from the service module, the 'Chang'e' spacecraft finally changed its orbit and approached the edge of the atmosphere!
At this moment, the "Chang'e" spacecraft successfully appeared at the boundary of the atmosphere, and it suddenly attracted the attention of the world. Space centers, space enthusiasts, and the entire Chinese people all over the world were drawn to the heartstrings of that spaceship. with.

If the manned moon landing is a marathon in sports, then this is the last 100 meters of the marathon.

To successfully land on the surface of the moon is indeed something to be proud of, it is indeed remarkable.But whether the fruit of victory can be successfully brought back from the moon to the surface is the key to declaring the final victory!

Whether this manned mission to the moon is a complete success depends on this!
"This is the 'Chang'e' spacecraft, and we have successfully entered the return orbit!" In the command module, Nie Haisheng communicated with the ground command center, and said in a calm voice: "We will contact the atmosphere in 5 minutes!"

"Received in Jingcheng, I wish you good luck!" The sound of "Received in Jingcheng" from the flight control center of Jingcheng was transmitted to the spacecraft of "Chang'e" and spread throughout the whole world!

Five minutes later, the 'Chang'e' spacecraft came into contact with the atmosphere, then entered the atmosphere, fell at high speed and rubbed against the atmosphere, and the temperature rose sharply, as if it was on fire.

When descending to a certain height, the 'Chang'e' spacecraft jettisoned the protective cover and opened the parachute.When descending to a certain height, the drogue parachute was abandoned, and the parachute was opened after flying for a while. Soon the command module of the "Chang'e" spacecraft successfully arrived at the earth and landed at the predetermined place - the Inner Mongolia prairie!

Immediately, the helicopter took off from different directions, carried out vigilance, and flew towards the landing site of the command module at the same time, and arrived at the landing site in less than 10 minutes.

Heavily armed soldiers slid down from the helicopter and landed on guard, while the helicopter hovered in the air.

After a while, the vehicle drove over.

After everything was ready, the hatch of the command module was opened, and the six astronauts walked out of the hatch one by one. waving salute.

The surrounding soldiers, journalists, and medical staff saluted the six astronaut heroes one after another, expressed their lofty respect to the six heroes and warriors who landed on the moon, and welcomed the triumphant return of the six space heroes with the highest etiquette. !
Then the medical staff conducted a preliminary inspection on the astronauts' bodies, and then took the astronauts away. After returning to Earth, they will undergo a comprehensive scientific inspection, and they will not leave the medical center until it is confirmed that there is no problem.

And from the moment the "Chang'e" spacecraft successfully landed on the grasslands of Inner Mongolia, the mission of the ground headquarters far away in the capital was over. Everyone celebrated wildly, cheered, applauded, and hugged each other.

Until this moment, the manned mission to the moon has not been considered a complete success.

After a simple celebration, the engineers and technicians working here either returned to the lounge to take a nap, or fell asleep directly on the work table.

After all, many of them have been at their posts for 24 hours, and some of them have even been at their desks since the rocket was ignited and launched, eating and lodging here, not even going home!

And now, the manned mission to the moon has been a complete success, they can relax their hearts, have a good sleep, and go home to be with their families. In the next period of time, they will usher in a one-week long vacation!

But the command center is relaxed, and some departments are ushering in a busy time. For example, the medical center has to conduct a comprehensive inspection of the six astronauts to ensure the health of the astronauts. Every astronaut is a precious asset of the country.

For example, some research centers need to study the samples brought back from the moon. After all, the lunar soil and ores brought back by the previous lunar exploration projects are not as good as those taken by people this time.

Of course, the most important thing is helium 3. The helium 3 extracted in 3 days has been brought back to the earth, and these helium 3 will play a vital role in the miniaturization of controllable nuclear fusion, and will also play a role in aerospace aircraft. plays a key role.
