With the blessing of rocket recovery technology, the "Magic Arrow" series of rockets has shown a launch efficiency that is indeed not at the same order of magnitude.

The ability of artificial intelligence, which uses quantum computing power, to calculate launch orbit data has also been greatly improved.

So just 8 days later, the backup star of the first lunar exploration satellite of Flint Space was ready to be launched again at the insistence of Jian Yushu.

Ye Ziheng looked at him helplessly: "You know, it's not a particularly good launch window now." This time, the requirements for fuel are higher. There are far fewer opportunities to adjust the track like last time. Now it's too late to postpone the launch. ”

Jian Yushu shook his head: "The same two launches, with one experience, after a comprehensive review and analysis, the team is confident." Even if it fails, it makes sense. Mr. Gu said, take the money to burn, and also train this team. ”

Ye Ziheng no longer persuaded him.

This is obviously the top, and it is not this way to burn money.

He only said: "What if it fails again this time? What will you do next time? Will you still carry out your 'month-by-month' plan?"

Jian Yushu's expression was solemn: "Of course it will be executed!" But don't worry, if it doesn't succeed this time, Mr. Gu decided to assemble a giant satellite in low-earth orbit first, the kind with special thrusters, and then go." ”

Ye Ziheng opened his mouth wide: "Assemble? Want to play space docking?"

Jian Yushu nodded: "That's right!"

Ye Ziheng really didn't know what to say.

Even the Chinese officials have not mastered the space docking technology now.

On the ground, the brother company Aerospace Science and Industry Group has been tackling key problems in this area for 13 years. Although the official sample was produced as early as eight years ago, the docking experiment and separation experiment have been done hundreds of times, and it cannot be said that it has been completely mastered.

Everything will have to wait until a real space docking experiment, which was originally planned to be carried out the following year.

This involves the proper operation of hundreds of sensors, thousands of gears, and tens of thousands of components.

Just to realize that "month-by-month" plan, now even space docking has to start playing?

Ye Ziheng felt that the times had really changed.

It's true that how much money people have, how much they swell.

There were too many places to complain, and he was silent all of a sudden.

Forget it, as far as his position is concerned, such a Party A is a good Party A.

To Party A, we must serve well.

So he once again told the commander of the launch command hall to do his best.

For now, let's hope that this launch will be successful.

If it fails, it is possible to harvest a mission to launch a giant satellite that can be docked and assembled in space, but it is also possible that Mr. Gu suddenly figured it out and felt that it was better not to play like this first.

It's still more secure to succeed.

At least after the successful launch of this time, the original "month-by-month" plan still has a lot of tasks, and Mr. Gu will at least continue to implement it with great confidence.

When it was time to launch, the launch phase of the rocket in just a few minutes was still successful, and the first stage of the rocket was recovered.

In low-Earth orbit, at least the satellite is in orbit.

But Ye Ziheng did not relax, because it was like this last time.

To launch a spacecraft to the moon, under the current technical conditions, it is first necessary to fly around the earth several times, change orbit through the engine, and then pull the apogee of the orbit farther and farther away, and finally fly to the moon.

This is the most fuel-efficient.

This process will be very long, only twenty or thirty hours to fly around the earth.

So...... Ye Ziheng said: "It's normal now, let's go rest first, and come back when it's time to change tracks." ”

Jian Yushu nodded, this is the case.

Ye Ziheng glanced back at the orbit data on the big screen, hoping that after the next orbit change, it would still fly according to the established orbit.

……

After 57 hours, after a successful second orbit change, the satellite is now back to its closest point to Earth.

This time, the orbit change will be carried out at perigee, and if successful, the satellite will enter the lunar orbit and reach the moon after more than 80 hours of flight.

Last time, it was in this place that the problem occurred. Because of the deviation of the lunar orbit, under the amplification of such a long-distance flight, after the satellite reached the moon and slowed down, it never adjusted its orbit well, and finally lost contact.

Now, the critical time has come again.

Ye Ziheng couldn't help but feel a little nervous, and glanced at Jian Yushu, but this guy looked very calm.

"You are really calm, and Mr. Gu really trusts you, so you can arrange it like this. Ye Ziheng couldn't help but say.

Jian Yushu glanced at him strangely: "I don't understand technology, I'm just a supervisor." ”

Ye Ziheng was choked.

Well said and makes sense. Sure enough, it was just that Mr. Gu was not admitting defeat and set such a risky launch plan.

Jian Yushu sighed: "Actually, I'm nervous, but it's useless for me to be nervous." Let's hope the team can learn from the lessons of last time and make more precise controls. They did find out some of their own reasons as well. ”

Ye Ziheng nodded, stopped talking, and waited quietly for him to change the track.

The first two orbit changes were not wrong, so the satellite is in the right orbit, and it only needs to start the engine according to the predetermined plan and complete the acceleration at the predetermined time with the predetermined thrust.

It's a very delicate computational work.

While the propulsion is being carried out, the spacecraft is also losing mass on the other side. Speed is related to mass, so the entire calculation needs to be calculated for multiple variables that are constantly changing.

Ye Ziheng doesn't care about these, he only needs to see if there is any deviation between the recalculated orbit data and the scheduled orbit data after the orbit change acceleration is completed.

If there is a deviation, the next adjustment plan needs to be recalculated and the new data will be sent.

So, if there is no problem, it is the best.

The process of orbit change acceleration is very fast, and after the orbit change is completed, new orbit data is being calculated and generated.

Ye Ziheng and Jian Yushu both looked at the big screen expectantly.

After a while, there was a deathly silence in the command hall for a few seconds.

Ye Ziheng's face was ugly, and sure enough, he ...... There was another deviation.

But it has not yet reached the point of irreversibility, and this time the deviation is much smaller than the last time.

Now, you need to wait for the track adjustment scheme to come out.

To calculate the remaining fuel, it is necessary to calculate the optimal time to change orbit and the standby time to change orbit.

He patted Jian Yushu on the shoulder: "It's much stronger than last time." ”

Jian Yushu nodded, but sighed slightly: "However, the launch window is worse than last time, and the fuel consumption is ...... It's a lot better than last time. ”

Ye Ziheng complained in his heart: Now that I know that I am worried about this, I have already advised don't be so anxious.

With the blessing of quantum computing and artificial intelligence, the calculation is indeed much faster.

The answer was not long in coming: fuel left, three more chances!

When you get to the moon, slow down once.

If the deceleration phase is successfully completed according to the new data, only one minor adjustment is needed to get into the predetermined track.

If this adjustment doesn't work out, there's only one chance left.

Ye Ziheng's face was not very good-looking.

In fact, if you really want to count it, there are only two chances.

He really can't trust the young team of Flint Aerospace.

But at this time, you can't make rash suggestions.

After all, there is a question of responsibility involved.

He looked at Jian Yushu and asked solemnly, "What do you say?"

Jian Yushu said in a deep voice: "Of course, it will be implemented according to the adjustment plan! It's all come to this point, can it still be suspended?"
