I have a little black hole

"Here is the "Xuantu", preparations are completed before the moon landing, and we will officially start the moon landing when the next round of flying arrives from the position!

'Gaia' command center, please confirm whether the moon landing procedure is normal!"As the commander of this mission to the moon, Tong Huamin started the final confirmation of the moon landing with the earth after the system self-check was successfully completed.

At this time, a scene of tension and busyness in the command center of the'Gaia' base. At this last moment, it would be strange if they are not feeling nervous at the moment!

Even if various detectors have been launched to the moon many times before, the reliability of the overloaded manned spacecraft has also been verified many times, but the mentality when there is no astronaut can be the same as when there are real astronauts and landed with the spacecraft. The mentality is completely different, not to mention that my boss is still on it!

"No. 2, is the moon landing procedure normal?" Zhao Feiyang, the commander of the moon landing project, rang in the control center.

"Report No. 1! There is no problem with the manual inspection, and the origin re-examination has also passed smoothly, and the moon landing operation can be carried out!" Station No. 2 responsible for the program inspection reported loudly.

Hearing this answer, Zhao Feiyang nodded with satisfaction and connected to the "Xuantu" lunar space station, and said with a certain tone: "Here is the "Gaia" command center! Everything on the ground is re-checked, and the origin re-check is normal, The lunar landing program can perform lunar landing operations!"

After hearing this reply, Tong Huamin issued a command to execute the lunar landing order with firm tone. Lei Tiantang and three other astronauts who had entered the command module of the lunar spacecraft also confirmed all normal responses respectively. The mission-critical node has arrived!

The atmosphere here is the easiest, because the entire moon landing procedure is completely controlled by the set intelligent program when there are no abnormalities, so before landing on the moon, what they can do Very little.

It is not a simple matter to operate this 102-ton "Houyi" lunar spacecraft assembly to the landing platform accurately. This complex and delicate operation is still left to the reaction speed. Microsecond-level intelligent program to control well.

Under normal circumstances, it is almost impossible for such a big guy to want a safe soft landing on the lunar surface, because if the lunar surface is not strengthened by treatment, such a heavy spaceship is considered to be no matter how good the operating procedures are, and it is landing. It will also sink into the lunar surface later, because the lunar surface is as soft as the earth's soil.

Although the structure and physical and mechanical properties of the lunar soil layer on the surface of the moon are hard, there is no need to worry about the lunar astronauts falling into the lunar soil, but this does not mean that it can bear such a heavy big guy with 6 support legs To support.

Once the spacecraft assembly is trapped after landing, the uncertain situation will be more, so for the safety of astronauts, in the early construction process, in addition to the construction of a large number of solar panel arrays on the moon surface outside the base In addition, a platform for large-tonnage spacecraft landing was specially constructed in the main landing area of ​​the spacecraft.

However, because the construction materials are very precious, this landing platform only uses mechanical equipment to beat and compact the area. A more professional platform can only be built when there are sufficient resources in the future.

Now, in the eyes of hundreds of millions of people on Earth, the "Houyi" spacecraft assembly successfully separated from the "Xuantu" space station at the predetermined orbital position, and officially began the journey to the moon!

The first thing to start with is the auxiliary engine for direction adjustment. Under the control of the program, they precisely adjusted the track and direction of the spacecraft assembly and began to fly along the planned landing curve.

At a height of 6800 meters from the moon, the main deceleration engine successfully ignited. Under its huge reverse thrust, the descent speed of the assembly began to decrease rapidly, and the auxiliary engine for direction adjustment was also constantly fine-tuning the position of the assembly. Aim this giant monster precisely at the landing platform.

Fortunately, the moon landing process has been verified by 7 successful landings, and 3 times have successfully simulated the manned landing. If you add the previous lunar probes and various forward bases, The number of landings of construction materials, then this number has increased to 22!

After so many successful landings, Infinite Gravity Group has accumulated a wealth of lunar landing experience, so at this time, whether it is the Earth Control Center or the "Xuantu" space station, there is at most some tension, but more Emotions are looking forward to!

At a distance of 300 meters from the lunar surface, the speed of the entire assembly has dropped to 10 meters per second, and this speed is still decreasing rapidly. When the assembly is 100 meters from the lunar surface, the speed drops to 6 meters per second, now this descent speed is already safe to land.

At this point, everyone's mood is relaxed, because even if the distance and descent speed are in trouble, the safety of the astronauts in the spacecraft will not be affected.

Lei Tiantang's attention at this time has changed from observing various landing data, to watching the final landing process of the spacecraft assembly through the ultra-clear camera on the outside of the spacecraft with people watching live broadcast on the earth, because this time is really No need for them to do anything.

Of course, at this time, the main deceleration engine did not stop working, but continued to provide reverse thrust for the entire assembly, until the spacecraft assembly was only 5 meters away from the moon, it began to reduce the thrust, this time the spacecraft assembly The descent speed has been reduced to 0.5 meters per second.

After Lei Tiantang and the three astronauts felt a slight shock, the landing process of the entire spacecraft assembly was completed very smoothly. Everyone who watched the entire landing process was excited to celebrate, because the mission can be here Say it has been a complete success!

Of course, it is still a little bit worse, because it has been said that this moon landing spacecraft is a combination. Of the weight of 102 tons, the weight of the command cabin and the return cabin is only 25 tons, and the remaining weight is Construction of materials and scientific research equipment used in the forward base.

Now the entire assembly has landed safely on the moon, but because the entire assembly is landed in the safest vertical landing mode, the distance between the command module where Lei Tiantang and the three astronauts are located is still It is 8 meters high.

From here to the moon, they have to go down the ladder. Even if the gravity of the moon is only one-sixth of the earth, the distance between these two floors is a little dangerous if they are not careful.
