The improved version of the Long March 5 ship Niangxing was completed, and there were no uncontrollable problems.

It’s not that there are no problems and no one can achieve perfection, but as long as the problem is within a controllable range and the consequences can be withstood, it is acceptable.

Yuanwang No. 1 turned around again and took everyone to look at Xu Xingchen:

"Commander, the launch and simulation are completed, the data is normal, and it can be launched."

Xu Xingchen nodded slightly and asked:

"When exactly will it be launched?"

Yuanwang No. 1 said:

“Now…or tonight.”

Xu Xingchen asked curiously:

"Is there any difference between these two times? Is it easier to observe at night?"

Yuanwang No. 1 explained seriously:

"The selection of the time window for rocket launch actually depends on the type of payload transported by our rocket.

"If it is a reconnaissance satellite, spacecraft, and space shuttle, these payloads usually use 'LEO low-Earth orbit', which should now be said to be 'near-Star orbit', with orbit altitudes within a range of 200 kilometers to 1,500 kilometers from the planet.

"In addition to temporary reconnaissance satellites that fly down to the critical point of satellite orbit and pursue high resolution to see things on the ground, most of the normal orbits of other normal near-planet spacecraft are in the range of 500 to 1,200 kilometers.

"For payloads that are destinations with near-planet orbits, the rockets are sent directly to the target orbit.

"There are only ten minutes to half an hour in the time from launching to entering orbit. Moreover, the satellites run around the planet for more than ten laps a day, and are not sensitive to time nodes and can basically be launched at any time.

"However, if it is a manned spacecraft, in order to prevent the launch failure and facilitate the rescue of personnel, it is usually launched during the day.

"If it is a communication type satellite such as global positioning, most of them will enter the 'GEO planet synchronous orbit', which belong to the 'high-orbit' satellite.

"The height of the synchronous orbit of the earth is 35,786 kilometers, and the height of the synchronous orbit of our planet is 55,228 kilometers.

"For payloads targets with planetary synchronous orbits, rockets usually do not send satellites directly into synchronous orbits, but first send them into a 'GTO synchronous transfer orbit'.

"The synchronous transfer orbit is an elliptical orbit, with the near-planet point fitting with the near-planet orbit, and the distant star end fitting with the planet's synchronous orbit.

"This kind of satellite will start from the near-star orbit, follow the elliptical arc of the transfer orbit, fly from the near-star end to the far-star end, and then enter the planet's synchronous orbit by itself.

"This transfer process takes several hours, and the synchronous satellite will follow the planet and its position in the sky remains relatively unchanged, but the rocket launches will fly eastward.

"So if launched at night, the satellite arrives at the target orbit and unfolds the solar panels, it will soon enter the daytime and can get energy replenishment.

"If it is launched during the day, it may be at night when you arrive. The satellite can only rely on the battery it carries to survive the first night.

"Although satellite design usually meets this demand, it still reduces a certain tolerance rate, so it is usually chosen to launch at night.

"For lunar exploration satellites, lunar spacecraft usually need to land when the moon enters the morning. At this time, the moon will not be too hot. The light is conducive to confirming the lunar environment, that is, when the moon phase is a ‘new moon’.

"This time node corresponds to the beginning of each month of the lunar calendar, so the launch time of several Apollo spacecraft is within the range of the first to the sixth day of the lunar calendar.

"In fact, the opportunity to land on the moon at designated locations is only one day per month. If the launch is determined to be postponed by one day, the landing location will have to be transferred accordingly, or it will be directly postponed by one lunar month...

"There are two types of payloads we are going to launch this time. The spacecraft has to go to the near-star orbit, and the satellite has to go to the synchronous orbit, so it's OK for both day and night..."

After Xu Xingchen's brain evolved, he directly digested these general content after listening:

"I understand, isn't our spacecraft experimental in nature? There is no actual manned manned, no ship girl, only some small animals, so let's accommodate the synchronous satellite.

"Then, when the ship girl is about to take off, the satellite will be sent to the ship girl. There is no need to bring a synchronous orbit satellite separately, so it will be launched during the day."

Yuanwang No. 1 smiled and nodded:

"Then let's launch tonight. I want to watch the rocket launch with my naked eyes. Unless the distance is very close, it will still be more spectacular at night. Unfortunately, everyone went out..."

Xu Xingchen sighed slightly:

"There is still no news about the situation of the deep sea mother. Those deep seas still only know how to retreat... they are not enemies of us at all, they only look for soft persimmons..."

Speaking of this, Xu Xingchen suddenly thought of something:

"Aoge, please send a message to the Joint Fleet to remind Shoto, Yamato, Musashi, and others to prevent deep-sea raids...it should be said to be deep-sea tides..."

Chaoge immediately agreed to do it, and Xu Xingchen discussed with the scientific research ship girls the relevant plans for future transformation of the ship girls, and the plan for launching satellites.

The relevant design has been basically completed and the candidates have been basically determined. Now we will add some details to strive for safety.

Before the first rocket was launched, it started to organize manned space flight. It was really outrageous. In fact, I just felt that I could not fail...

In the afternoon of the same day, Yuanwang 2, escorted by a team of transformed ship girls, took a J-15 fighter to the Longbow Islands and unfolded its hull in the bay of the Longbow Islands.

Yuanwang 4 also went to the base in the Bay of the Flying Eagle Islands under the escort of the transformed ship girl and expanded the hull in the Bay of the Flying Eagle Bay.

Yuanwang 3 went to the small inland sea in Yingzhou. They spread their hull separately and tracked and observed the rocket launch process on the sea surface.

Yuanwang 1 and Neptune went to the launch site, and several other information reconnaissance ships such as Polaris stayed in the control center to dispatch.

There are only a few ship girls in this team, but after each ship girl unfolds the hull, her ability is equivalent to a professional space support team.

Xu Xingchen himself took Chaoge to the launch site.

The Yunhai Rocket launch site is outside the Yunhai Home Port Port Area, on the beach not too far from the pier.

Even if Xu Xingchen stood in the building of the scientific research center, he could soon see the big rocket after it took off.

However, the moment of launch cannot be seen, and at the same time, the observation from a distance is obviously not as shocking as when I arrived at the scene, so Xu Xingchen ran over.

The rocket designed by himself and the ship girls were copied and modified from Changwu, and the launch site planning was also modified from Changwu's launch site.

The launch tower also looks exactly the same as the Changwu one, but it is just a similar appearance. The core and work distance of the two are completely different.

Human launch towers are normal mechanized engineering equipment. Before launching the rocket, they must be tested and then moved to the launch pad.

The launch tower of Ship Girl is actually a Ship Girl airport console inside.

The rockets of ship girls are not produced in segments like humans. After assembly, fuel is injected before launching.

Instead, it is produced as a piece of ship girl equipment and consumes resources using manufacturing equipment. Its own characteristics are basically the same as that of ship girl equipment.

A large rocket with a normal height of nearly 60 meters and a weight of nearly 900 tons is a "model" less than one meter when it was produced as a ship girl's equipment.

Load the rocket into the airport console like a ship girl's plane, install it into the console of the launch tower to execute the deployment and expansion command, and it will become a normal rocket size.

Then the spacecraft produced in the same way and the satellites were installed and deployed, and finally the things that were scheduled to be launched into the spacecraft, and the rocket launch was ready.

The entire process does not require a large number of workers and engineering equipment. Yuanwang No. 1 and Xu Xingchen themselves can carry the rockets to install them.

A group of ship-renovated women were arranged to maintain order on the spot to prevent them from being affected by ordinary humans and ship-women.

Such production and deployment methods may have higher production costs than normal production by human industrial production, but the time, logistics and management costs are minimized.
