The day before Artemis IV flew to the moon, the last space shuttle on the Advance space station, Storm, broke away and returned to Earth with seven astronauts, including the last Li Sheng.

After the Pioneer shuttle detached, there was only one space shuttle left, and in order to send all 26 astronauts down, the H1 space shuttle was used in advance, and the 19 astronauts were sent down in two separate parts.

It wasn't until the early hours of February 24 that the last seven astronauts left on the shuttle after a thorough inspection, four days later than expected.

In the rounds of rigorous alternating inspections of humans and robots, the Advance has completely reached the rotation conditions.

Except for its initial configuration, all the other docked spacecraft have been detached, and the current mass of the Advance is almost 1,695 tons, including the various experimental equipment and large quantities of materials that it has brought with it since then.

It has now been 113 days since it was fully built, and it has taken nearly four months on the ground to examine the unprecedented man-made object and allow astronauts to adapt to life.

Now, it is about to be put into trial operation for the first time after a long period of testing.

In the ground command center in the capital, Ye Changsi is commanding the engineers of the Space Bureau and the Xinyuan Base at the same time as the commander-in-chief.

The initial design of the Qianjin space station was completed by Anderov, and after the formal construction phase, Seryov took over, and finally Ye Changsi was also deeply involved.

It stands to reason that it is more appropriate for Seryov to come now, but he is still eating sand in the Gobi Desert in the northwest, and Ye Changsi will command the trial operation work for the time being.

In addition to him, Seryov, He Ruo, and Shen Zuozhou jointly served as deputy commanders-in-chief, and now only Shen Zuozhou and Shen Zuozhou are working hard to cooperate with him.

Shen Zuozhou has not been in contact with the Advance project, which should have been the work of Academician She, but the latter has officially decided to leave the front-line work after March and enter a substantial semi-retirement state.

The Advance is unprecedented in terms of operational quality, technical level, configuration and other aspects, and even if the space agency participated in the manufacture of six important service modules, the degree of mastery of it is not profound.

Previously, when the construction of the Qianqian was officially started, the space agency showed unanimous disapproval and resistance, because its design time was too short, and Xinyuan had never had experience in the design and operation of large space stations.

The construction of a space station is not only a matter of technology, but also of gaining experience, very similar to the design of a warship.

The tonnage of a destroyer is only a few thousand tons, and an ocean-going freighter is tens of thousands of tons casually, but the design difficulty is definitely higher than the former.

The hull design of warships must consider many aspects such as protection, anti-water ingress ability, redundant power, balance between speed and endurance, and maneuverability, which has far exceeded the complexity of the design of civilian ships.

More importantly, all kinds of radar electronic equipment, weapon systems, etc., required by modern warships, and the electromagnetic compatibility test of various equipment of modern warships will take one year.

The same is true for the space station, the technical difficulty of the large cabin for pure space tourism is mainly in the materials and craftsmanship, but for a behemoth like Advance, every detail must take into account the operation of the space station as a whole.

This is definitely a super project that is too complex to measure, requiring a lot of experience and sufficient pre-validation testing, and the risk of going straight to the front is simply so high that it makes your scalp tingle.

The reason why the space agency spent a lot of money on this project is to "save" this huge investment super project and prevent it from causing the largest space accident in history due to low-level mistakes.

But as the space agency became more involved, things started to get weird.

In the construction drawings handed over by Xinyuan, there are a large number of designs that they don't understand, either because they don't know what the function is, or because they know the function but don't understand why they want to take such a design scheme.

Then the engineer sent by Xinyuan would explain the reason, and the space agency was surprised to find that the original design of the Advance was not only not rough, but rather excessively refined, taking into account almost every detail.

Shen Zuozhou was involved in the manufacture of the noise reduction part of the service module and the gravity/weightlessness adaptive ergonomic equipment in the cabin, and then found that the noise reduction design and gravity-related optimization of the main cabin of the Qianqian were much better than those of the Tiangong space station.

After the main body of the Advance was fully built, he had a strong delusion:

It is impossible for a person or a dozen people to design it in a short period of time, and it feels more like getting ready-made drawings and doing it, so that there are almost no major defects after completion.

It was designed and built in one go, and it went incredibly smoothly.

Although there have been "rumors" that Xinyuan is behind a group of overseas Chinese concentrated in the high-tech field, it is impossible to find such a level of drawings even if NACA's database is emptied.

In the end, he could only think that those researchers were too perverted, and the leaders were even science and engineering geniuses, so that they could accomplish such a miracle in a short period of time.

The space agency has been involved for so long, but no one dares to guarantee that they fully understand this space station, so much so that Shen Zuozhou, named the deputy commander-in-chief, is actually desperately trying to learn from Ye Changsi about this space station.

As for He Ruo, who only entered the capital to work later, he was even more in the stage of looking at it with his head bored.

And now Ye Changsi is focusing on the core rotary control module that is transmitted remotely from the base.

The same information is also displayed on the console of the Pilot Module of the Advance, which further demonstrates its high independence ability.

What Shen Zuozhou saw was a three-view of the Advance's frame, each part filled with different degrees of blue, and there was a constantly flashing red dot in the center of the front view, overlapping with a slightly larger green dot.

"Green is the geometric center of the Advance, based on factory data from each cabin and frame structure.

We measured their mass, size and center of gravity distribution in advance, and then wrote them into the computer, and as long as the completely unloaded advance number was installed in place, its center of gravity deviated from the center of rotation by no more than one thousandth.

And you know that all of the supplies that we provide for the Advance need to be encapsulated in a specific way, so their data can also be considered almost standard, and the current center of gravity can be corrected when it is fed into the computer.

Of course, these are all non-rigorous theoretical references, and are only used as a basis for adjustment after rotation, and the actual situation is far from so simple. ”

Ye Changsi is not only telling Shen Zuozhou and He Ruo, but also indirectly imparting experience to Li Sheng, the captain of the Advance.

The latter has just come down and it will take time to get used to it, but it hasn't stopped moving forward like a good spaceship captain.
