Time passed slowly. In the evening, the few scientific research ship girls who were going out were all in their seats and were ready.

Xu Xingchen also followed Yuanwang 1 and the on-duty ship girl from the launch base to have dinner at the canteen here, and then directly entered the launch waiting time.

Xu Xingchen followed the ship girls who were not on duty and climbed to the roof of the tallest building in the launch base except for the launch tower - the base apartment and canteen.

Although the ship girls around them are basically native ordinary transformed ship girls except Chaoge, Yuanwang 1, and Neptune, they have been working here for so long and already know what the rocket is.

They have been busy here for more than three months, and now it is finally time to officially start, and they are waiting very excited and excited.

The rocket is nearly 60 meters high, like an eighteen-story building weighing 900 tons, and can catch up with some small frigates.

It stood quietly on the launch pad. Even if it opened enough distance, it still felt very shocked. When this thing really flew up, the picture was unimaginable...

The key is that more than 900 tons of things can fly into the sky. Can they also fly into the sky when you unfold your hull? It’s exciting to think about it.

It was just because Xu Xingchen, the leader, was a little restrained, tried hard to control his emotions and movements, and stood and waited honestly.

Neptune and Yuanwang 1 both opened the ship's ship, and all the relevant equipment on the body was running, maintaining the working observation record.

Seeing the sun completely disappearing and the sky gradually darkened, Xu Xingchen and others were a little anxious, but they felt that they were not professionals, so they did not disturb the attentive Sister Yuanwang.

Like those ordinary ship girls, Xu Xingchen was patient with his curiosity and looked at the rockets in the distance waiting for time.

When night falls completely, the launch time node finally arrives.

Yuanwang No. 1 looked at Xu Xingchen beside him, and his expression was rare and very serious. He said:

"Commander, the current time window is appropriate, the parameters and status of the rocket and payload have been calculated again. It is completely normal and can be launched. Please order it."

Xu Xingchen didn't think too much, and was even a little worried that his ink tracks would affect his work, so he said two words without hesitation:

"ignition!"

Yuanwang No. 1 immediately repeated the instructions:

"ignition".

When the North Star in the control center receives the message, immediately press a launch button on the operating table in front of you and repeat:

"ignition!"

After Xu Xingchen gave the instructions, he immediately stared at the Rocket with all his attention.

The words from Yuanwang 1 and Polaris came out almost at the same time, so as the two of them spoke, surging white smoke had already flowed out from the rocket.

The smoke formed by the combustion of fuel almost enveloped half of the launch pad, which was nearly ten floors high.

Then the big rocket surrounded by rolling eyes, this 18-story-high big guy, also rose slowly from the launch pad with blazing flames.

It gives people the feeling of a building flying up under the flames.

The harsh flame ejection, along with the total out of control, echoed throughout the launch site.

Watching the big guy slowly take off, Xu Xingchen couldn't help but shout, and along with the cheers around him, he kept sending the big guy up to the sky.

Watching it go further and further away, from a ball of fire to a ball of light, from a ball of light to a spot of light, and then a line of fire was drawn on the deep dark sky

When the rocket turned into a spot of light, with the fluorescence reflected by the sky, it turned from rising to flying eastward, Xu Xingchen's mood calmed down a little.

Then Xu Xingchen realized that the rocket flew directly. He didn't seem to hear the countdown. He was not in the control center, so he didn't?

However, when Yuanwang 1 responded, the Rockets ignited directly, and there was no time to add a countdown...

Xu Xingchen was a little surprised and confused. He subconsciously turned his head behind him and asked Yuanwang No. 1 with uncertainty:

"Well, Sister Yuanwang, we don't seem to have a countdown... Is there any problem with the control?"

Yuanwang No. 1 was stunned for a moment, and then immediately couldn't help but smile:

"No problem, commander, don't worry, we didn't design this link.

"The function of countdown is to remind and guide personnel from various departments to enter the final working rhythm simultaneously.

"There are only a few of our relevant personnel in total, so there is no need to coordinate through countdown and passwords."

Xu Xingchen confirmed that there was no problem. He breathed a sigh of relief and asked with regret:

"In other words, in the future, we will not have countdowns like this when we launch rockets?"

Yuanwang No. 1 smiled and said:

"If the commander likes it, you can add it, which will not affect the pace of work."

Xu Xingchen shook his head after a very brief hesitation:

"Forget it, don't bother, come as you can, how can you do it conveniently? I'll see the Rocket. Now it's going to fly east? It's going to the equator behind it, right?"

Yuanwang No. 1 nodded and explained:

"Yes, with the planet's rotation from west to east, providing the initial acceleration of the rockets and spacecraft, our rockets will continue to fly eastward.

"At the same time, the lower the latitude, the greater the acceleration provided by the planet's rotation, so for most spacecraft, the closer the launch base is to the equator, the better.

"And the first time we launched a synchronous satellite, which must be directly anchored above the equator, so there will be a process of transferring orbits..."

Xu Xingchen subconsciously said:

"If the launch site is directly built on the equator, will there be no orbital change process?"

Yuanwang No. 1 smiled and said:

"It's theoretically, but during the launch process, the satellite enters orbit, and the orbit conversion process, fine-tunes must be made.

"Even if you take off directly at the equator, you must confirm that the position of its upwards is indeed the equator, and there is no natural deflection due to problems such as wind direction.

"There are basically certain deflections, so you basically need to adjust it slightly, and the adjustment process cannot be saved.

"At the same time, there may not be a suitable launch location at the equator. It is better to find a place with a more complete industrial foundation and living conditions to launch at a relatively south location."

Xu Xingchen suddenly realized:

"So the launch base of the earth was chosen on Qiongzhou Island, and there was no magical work that continued to go to Nanyang..."

Xu Xingchen talked with Yuanwang 1 for a while, continued to learn and become familiar with the basic knowledge related to aerospace, and time was passing rapidly.

Half an hour later, Yuanwang No. 1 suddenly blinked hard, and reported happily:

"Commander, our spacecraft has successfully entered orbit! We have begun to fly around the planet, and the animals on the ship are now completely normal!"

Xu Xingchen breathed lightly:

"Okay, great, is the satellite going to wait for the second half of the night..."

Yuanwang No. 1 nodded and said:

"Yes, we launched four synchronous satellites at a time, and the earliest one has to wait until our local time to enter orbit in the early morning, so the commander will go and rest first."

Xu Xingchen immediately shook his head and said:
Chapter completed!
