I Have a Little Black Hole

This is the 'Xuantu', the preparations for the moon landing are completed, and we will officially start the moon landing when the next round of flight arrives at the detachment position!

'Gaia' command center, please confirm whether the lunar landing procedures are normal! As the commander of this lunar landing mission, Tong Huamin started the final lunar landing confirmation with Earth after the system self-check was successfully completed.

At this time, there was a tense and busy scene in the command center of the 'Gaia' base. At this last moment, it would be strange if they were not nervous at the moment!

Even various probes that have been launched to the moon many times before have verified the reliability of the manned lunar landing spacecraft many times, but the mentality when there are no astronauts can be compared to when there are real astronauts landing with the spacecraft. The mentality is completely different, not to mention that your own boss is still on it!

No. 2, is the lunar landing procedure normal? Zhao Feiyang, the commander-in-chief of the lunar landing project, rang in the control center.

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

Hearing this answer, Zhao Feiyang nodded with satisfaction and then connected to the 'Xuantu' lunar space station, and said in a certain tone: This is the 'Gaia' command center! The ground manual review is normal, and the origin review is normal. The moon landing program can perform moon landing operations!

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

The atmosphere on their side is the most relaxed, because the entire lunar landing program is completely controlled by the set intelligent program when there is no abnormal situation, so before landing on the lunar surface, what they can do rare.

It is not a simple thing to operate the 102-ton 'Houyi' lunar spacecraft assembly to accurately land on the predetermined landing platform. This kind of 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 heavy guy to make a safe soft landing on the lunar surface, because if the lunar surface is not treated and reinforced, even if such a heavy spacecraft is well controlled by the operating program, it will land on the ground. Later, it will sink into the moon surface, because the moon surface is as soft as the earth's soil.

Although the structure and physical and mechanical properties of the lunar soil layer on the lunar surface are hard,

There is absolutely no need to worry that the lunar astronauts will sink into the lunar soil, but this does not mean that it can withstand such a heavy big guy with 6 supporting legs.

And once the spacecraft assembly sinks in after landing, there will be many more uncertain situations. Therefore, for the safety of astronauts, in the early construction process, in addition to building a large number of solar panel arrays on the lunar surface outside the base In addition, a platform for the landing of large-tonnage spacecraft was specially built in the main landing area of ​​the spacecraft.

However, because building materials are very precious, this landing platform only used mechanical equipment to beat and crush this area. More professional platforms can only be built when resources are sufficient in the future.

And now, in the eyes of hundreds of millions of people on the earth, the 'Houyi' lunar landing spacecraft assembly successfully escaped from the 'Xuantu' space station at the predetermined orbital position, and officially began the journey to the moon!

The first thing to do is to adjust the direction of the auxiliary engines. Under the control of the program, they precisely adjust the orbit and direction of the spacecraft assembly and begin to fly along the planned landing curve.

At a height of 6,800 meters from the lunar surface, the main deceleration engine was successfully ignited. Under its huge reverse thrust, the descending speed of the assembly began to decrease rapidly, and the direction adjustment auxiliary engine was also constantly fine-tuning the position of the assembly. Aim the behemoth precisely at the landing platform.

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

So many successful landings have allowed the Infinite Gravity Group to accumulate rich experience in landing on the lunar surface, so at this time, whether it is the Earth Control Center or the 'Xuantu' space station, the people at most are a little nervous, but more Emotion is anticipation!

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

At this point, everyone's mood is relieved, because even if there is a problem with this distance and the speed of descent, it will not affect the safety of the astronauts in the spacecraft.

Lei Tiantang and the others' 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 outside the spacecraft with the people watching the live broadcast on Earth, because at this time it is really Nothing needs them to do.

Of course, the main deceleration engine did not stop working at this time, but continued to provide reverse thrust for the entire assembly. It did not begin to reduce thrust until the spacecraft assembly was only 5 meters away from the moon. The speed of descent has been reduced to 05 meters per second.

After Lei Tiantang and the three astronauts felt a slight vibration, the landing process of the entire spacecraft assembly was completed smoothly. Everyone who watched the entire landing process was excited to celebrate, because the mission was here. Said it was a complete success!

Of course, it's still a little bit worse now, because it has always been said that the moon landing spacecraft is a combination. Of the 102 tons, the combined weight of the command module and the return module is only 25 tons, and the rest of the weight is Materials and scientific research equipment used in the construction of forward bases.

Now the entire assembly has indeed landed on the moon safely, but because the landing method of the entire assembly adopts the safest vertical landing mode, the command module where Lei Tiantang and the three astronauts are located is still far from the lunar surface. There are 8 meters high.

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