Chapter 421

Do your best and obey destiny!

Gu Lu has done everything he can.

The rest can only be obeyed by fate.

Gu Lu couldn't tell how sure he was.

Because in the face of that extremely low error tolerance rate.

Even the slightest influence from external factors may cause the entire moon landing process to fail.

Perhaps, this time, I really have to believe in metaphysics!

By the way, when talking about metaphysics, Gu Lu suddenly thought of a person.

Taking out his cell phone, Gu Lu dialed Su Xi's number.

The time now is six o'clock in the morning.

Su Xi probably hasn't woken up yet.

The phone rang for a while before it was answered.

"Teacher Gu, what's the matter? You called me so early in the morning. You don't know that you disturbed my sweet dream!" Su Xi's confused voice rang on the other side of the phone.

"Say, wish me luck!" Gu Lu's voice was heavy, with a hint of hoarseness in his voice.

Hearing Gu Lu's tone, Su Xi's sleepiness disappeared instantly.

Su Xi no longer meant to be joking, and asked nervously and worriedly, "Gu Lu, are you in any trouble?"

"Don't worry about this for now, just say, wish me good luck!" Gu Lu had a severe headache and said in a serious tone while sucking in the air-conditioning hissingly.

"I wish... I wish you good luck!" Su Xi said these four words stumblingly, and then asked in an anxious tone, "Gu Lu, where are you now? I'll be there right away!"

"You don't have to come over. Besides, you can't come over either. Forget it, hang up now. I have some very important things to do here. I'll call you back later."

Gu Lu, who had received the blessing buff from Su Xi, the European Emperor, decisively hung up the phone after saying this.

…………

Command center.

Gu Lu leaned back in his chair, rubbing his swollen temples, and raised his head to stare at the big screen in front of him.

Now more than three minutes have passed since Gu Lu sent the signal command.

The Chang'e-4 detector has yet to receive the new command from Gu Lu.

The detector is still performing the main deceleration stage according to the original operation.

You can see it clearly on a large screen.

The probe is gradually slowing down, and the distance from the lunar surface is constantly shortening.

The distance of nearly 200 kilometers is now only about 150 kilometers.

Twenty seconds later.

Exactly four minutes and thirteen seconds had passed since Gu Lu's order was issued.

Theoretically, at this time, the detector's control and navigation system has received new operating instructions.

Gu Lu and Wu Zheng simultaneously turned to look at the person in charge of the GNC system not far away.

The person in charge glanced down at the computer and said excitedly, "The detector command and navigation system has received a new command!"

Successfully received the command!

Everyone in the command center breathed a sigh of relief at the same time.

But no one had a smile on their face.

It is one thing to receive operating instructions, but whether this new set of operating instructions is feasible is another matter!

People don't think so.

This new set of operating instructions designed by Gu Lu in just seventy-two seconds has the ability to support a building that is about to collapse!

but……

Just like Wu Zheng said.

No matter what happens, the result cannot be worse.

It would be better to wait for Gu Lu.

What if a miracle happens?

…………

Three seconds later.

The main deceleration phase of the probe's moon landing process is completed.

Next, we will enter the second stage of rapid adjustment.

The hearts of everyone in the command center were tense.

They all knew that in the original operating instructions, the engine responsible for this stage was the No. 2 engine.

Now, the No. 2 engine is damaged.

Everyone is unclear about how Gu Lu solved this problem in the new operating instructions.

On the big screen.

The detector ends the main deceleration stage and enters the rapid adjustment stage.

Everyone could clearly see that the No. 1 engine that was originally scheduled to break away at this moment did not break away.

Instead, after the rapid adjustment phase begins, a thrust force of different angles and sizes is immediately generated.

At the same time.

Engine number four starts.

The variable thrust generated by the No. 4 engine and the thrust of the No. 1 engine are superimposed to achieve rapid adjustment of the detector.

this……

Everyone's eyes widened at the same time.

Because the scene where the detector crashed directly as everyone imagined did not happen.

The detector descends smoothly and adjusts its angle according to a certain acceleration.

If the No. 2 engine is not damaged.

The trajectory of the detector at this stage should be almost like this!

Things have become obvious.

That is, Gu Luzhen used a brand new set of operating instructions to let the No. 1 engine and the No. 4 engine complete the work that originally belonged to the No. 2 engine.

Everyone turned to look at Gu Lu.

Gu Lu was seen leaning on the back of the chair, with a rare smile on his face.

…………

The rapid adjustment phase only lasts about three minutes, which is shorter than the main deceleration phase.

The detector undergoes a rapid adjustment phase two minutes later.

Fuel ran out in engine number one.

According to the operating instructions input by the law in advance, the No. 1 engine separated from the detector to reduce the load on the detector.

Engine No. 1 detached.

The remaining work in the rapid adjustment phase is all taken care of by the No. 4 engine.

Since Gu Lu had designed the operating instructions a long time ago, the transition was quite smooth.

only.

The expressions on the faces of everyone in the command center immediately became ugly.

They know it very well.

Engine No. 4 is responsible for providing variable thrust during the hover phase.

But now most of the fuel is consumed in the rapid adjustment phase, and the remaining fuel in the No. 4 engine is definitely not enough to support the probe to hover in the air for too long.

If it cannot hover for too long, how can the detector reach the sky above the Von Kármán impact crater.

Everyone was full of hope just now.

I really thought Gu Lu could create miracles.

But now it seems that Gu Lu's behavior is really no different from the behavior of tearing down the east wall to repair the west wall!

That’s right!

The rapid adjustment phase was successfully completed.

But if the probe cannot land smoothly in the Von Kármán impact crater, all previous efforts will still be in vain!

"Professor Gu, do you know that your design will reduce the time the detector spends in the hovering phase, and the detector will not be able to reach the sky above the Von Kármán impact crater during the hovering time?" the person in charge of the propulsion system,

The expert wearing glasses found Gu Lu and asked urgently.

He had no intention of raising an army to accuse him.

But Gu Lu's operation of giving them hope and then making them despair the next second really made him feel very uncomfortable.

The successful completion of the rapid adjustment phase made Gu Lu feel a lot more relaxed.

Gu Lu looked up at the person in charge with a faint smile on his lips.
Chapter completed!
