Chapter 706: Return to orbit! (Two / three)

On New Year's Day.

Regardless of understanding space, almost half of China is rejoicing for the launch of the Xiangrui. Most people may not understand the difference between electric propulsion and chemical propulsion, nor do they understand what a Hall thruster is. However, as the first air-space aircraft that can safely travel between the surface and outer space, Xiangrui can be said to fill China This piece of blank.

On this happy day, however, a report released by the New York Times suddenly poured cold water on many people who were still excited.

In the report, the New York Times extracted some of the comments made by NASA spokespersons and processed them. At the same time, it quoted several paragraphs of other Silicon Valley aerospace engineers' views that the auspicious aeroplane was seriously flawed in design.

致命 And this fatal flaw may make it easier to get up and down.

The final result is likely to disintegrate in the atmosphere like Columbia ...

刚刚 This interview was just released, and it has been widely discussed on social media such as Twitter and Facebook.

When the report from the New York Times returned to China, it was even more outrageous. In particular, the 25-second video of the New Year's Day from Daohe just came out, and immediately overwhelmed the overwhelming reports about the successful launch of the Xiangrui.

Excitement is not getting excited.

Many people even sweated for Professor Lu who was still in the sky.

[Paralysis! Yankees just feel uneasy! Seeing our plane go up and cursing it! 】

【Can the plane be cursed? This is also a kind reminder! 】

【May not! I think this Yankee is definitely planning something, shouldn't he want to secretly hit it with a missile? 】

[Mig-25: As long as I run fast enough, the missile will not catch up with me (funny)]

【Pray for Lu Shen (Candle) (Candle) (Candle)】

【Wish you to be single for a lifetime to land safely (candle)】

【……】

Related topics quickly became hot search.

I also lost that Lu Zhou couldn't play with his mobile phone and couldn't brush his neckband, otherwise he would certainly be unable to help laughing.

不 Can't return home?

how is this possible……

10,000 steps back, even if he really can't return, and there is a spare escape cabin available, he can't really make fun of his own life.

At this moment, at an altitude of 400 kilometers.

The Xiangrui, which is operating in low-Earth orbit, has completed a series of basic operations, including orbital flight, pressure regulation in the spacecraft capsule, testing of the standby sanitary system, sleep under weightless environment, eating, etc. Exposed in space, observe the possible effects of cosmic rays on life activities.

After completing a series of flight tests and scientific expeditions, the cruise time has reached 23 hours and 50 minutes.

As planned, Xiangrui restarted the engine under the direction of the ground command, and was ready to return.

Sitting in the co-pilot position, Nie Yan, while checking the operation of the energy supply components, said in the voice of a flight attendant.

"Professor Lu, please put on your spacesuit and lie on the crew seat. This flight will return soon ..."

"I know, don't remind me." Lu Zhou smiled and said, gave a thumbs up to the two, "Come on, come back and let you go.

He's in a good mood now.

This time God is considered an addiction.

Of course, the most important thing is the 50,000 free experience and lottery opportunities.

Even if it is only for the 50,000 free experience, the cost of the test flight is not lost.

Bian Nieyun turned his head and smiled with a strong smile, but his palms were already sweating.

The difficulty of returning is no less difficult than launching.

Although the return strategy of Xiangrui is theoretically safer than that of ordinary reentry spacecraft, no one can guarantee that there will be no accidents. After all, he and Xiangrui flew so high for the first time ...

教授 "Professor, can you promise me one thing?"

Lu Luzhou: "What is it?"

"If you return safely this time ..."

"Stop!" Lu Zhou hurriedly raised his hand and interrupted Nie Yun's speech. "Don't hurry to stand now, I will promise you everything when I'm on the ground."

Just don't go too far.

Do not urge marriage.

However, Nie Yun did not appreciate it.

He squinted to see that Lu Zhou was obviously perfunctory, his hands suddenly left the console, and said with a sad expression.

"No, I must say now!"

Lu Luzhou: "..."

MMP!

A big man, can't you wait for an hour or two?

Sighing, Lu Zhou barely spoke.

"Okay ... then you say, but if I speak now, I can't promise you anything."

Yun Nieyun: "My request is very simple, promise me that this is the last time to go to heaven!"

Upon hearing this, Lu Zhou's expression of constipation suddenly appeared.

how can that be!

He is still alive in this life!

Looking at the determined expression on Nie Yun's face, Lu Zhou reluctantly compromised.

"At best, I promise you, this is the last time to fly on your plane."

Nie Yun thought for a moment, and nodded reluctantly.

"also!"

只要 Anyway, just don't be on his plane.

要 If something happens to this Nima, it must be nailed to the shame pillar of history.

After joining the army for so many years, he was so afraid of death for the first time.

"Okay, you are enough!"

Nie 晗 shook his head, reached out and pressed a few buttons on the control panel.

"The navigation system has been started. It is confirmed that there are no abnormalities in the channel, the energy supply device has been warmed up, and the No. 1 and No. 2 engines are on standby."

"Ready for derailment."

I restored the usual calmness and calmness, Nie Yun took a deep breath with her eyes closed, and opened her eyes again.

"Ignite!"

Uh ...

Regardless of whether it is a space shuttle, an aerospace aircraft or any other manned spacecraft, returning from low earth orbit is always a technical task.

As a co-pilot, Nie Yan first determined the "fuel" status of the Xiangrui. Among them, the remaining amount of deuterium and tritium mixed gas is quite sufficient, even if it is to go to and from the ground again and again, the only major loss is the solid state xenon in the working fluid compartment, and the remaining amount is only 21%.

After all, there is no certain thrust that cannot climb out of a gravity well. If you want to fly from the surface to near-Earth orbit, you must increase the amount of working fluid to increase the thrust of the engine at the expense of a certain specific impulse.

But if I just return to the sea, this work quality is more than enough.

Under the dual guidance of the ground command and the spacecraft's intelligent navigation system, Nie Yun controlled the Xiangrui successfully completed the orbital change, and entered the transitional orbit from the operating orbit.

At the same time, a stunning sound sounded in front of the semi-curved console in NASA's satellite control room.

"Target starts to return."

"May the Pacific be their destination," staring at the green dot on the screen, Aiden added viciously after the sentence, "except for the spacecraft, it is best not to leave the whole body. "

工 Several workers watching the movement of the spacecraft frowned fiercely ~ www.wuxiaspot.com ~ For the astronauts, this curse is too vicious.

Even if it's against competitors ...

I stared nervously at the green dot near the dense border of the atmosphere, and the engineer sitting in front of the console suddenly said.

"The movement track of Xiangyun is abnormal ..."

Aiden slammed his hands on the table, exulting: "They're out of order?"

Could it be that God heard his prayer?

If they really fall in the Pacific Ocean, the fleet stationed in Guam will be happy to help salvage.

"The return method they use is different from what we know ..."

The excitement in Xun's heart faded gradually, and Aiden, who realized that the situation might not be the same as his own, gradually frowned.

"What do you mean?"

"... only one possibility."

"what exactly is it?"

"They still have fuel left ..." They swallowed, and the engineer said with an incredible expression on his face.
