Chapter 707 Change Track and Return Home! (2/3)

Chapter 707 Change track and return home! (twenty three)

New Year's Day.

Regardless of whether they know about spaceflight or not, almost half of China is rejoicing at the launch of the auspicious ship. Ordinary people may not understand the difference between electric propulsion and chemical propulsion, nor do they understand what Hall thrusters are, but as the first aerospace plane that can safely travel between the surface and outer space, the auspicious auspicious can be said to fill the role of China in the This piece of blank.

However, on this happy day, the "New York Times" suddenly released a report that poured cold water on many people who were still excited.

In the report, the "New York Times" excerpted some of the remarks of the NASA spokesman for processing, while citing the views of other aerospace engineers in Silicon Valley, that the Xiangrui has serious flaws in design.

And this fatal flaw may cause it to be easy to go up and down to be difficult.

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

This interview has just been released, and it has caused widespread heated discussions on social media such as Twitter and Facebook.

And when the "New York Times" report came back to China, it caused a big uproar. Especially just in time for the 25-second video congratulating New Year's Day, which immediately cast a cloud over the overwhelming reports about the successful launch of the auspicious spacecraft.

Excited is not excited.

Even many people are sweating for Professor Lu who is still in the sky.

【paralysis! The Americans are just uneasy! Seeing our plane go up and curse it down! 】

[Can the plane still be cursed down? This is also a kind reminder! 】

【not necessarily! I think this Yankee must be planning something. Could it be that he wanted to shoot down with a missile secretly? 】

[MiG-25: As long as I run fast enough, the missile can't catch up with me (funny)]

[Pray for God Lu (candle) (candle) (candle)]

[I would like to use all of the above for a lifetime of singleness for the auspicious landing of the auspicious ship (candle)]

【…】

Related topics were quickly topped by hot searches.

It's also a pity that Lu Zhou can't play with his mobile phone at this moment, and he can't swipe his scarf, otherwise he would definitely not be able to stop laughing.

Can't go back?

how is this possible……

Taking 10,000 steps back, even if he really can't return to the flight, there are spare escape pods to use, and he won't really make fun of his own life.

At this moment, it is far above the altitude of 400 kilometers.

Auspicious, running in low-Earth orbit, has completed a series of basic operations including orbital change flight, pressure regulation in the spacecraft cabin, backup health system testing, sleep in a weightless environment, eating, etc., and 20 cases of vegetable and fruit seeds were exposed. .Exposure to the space environment and 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, the Auspicious Rui restarted the engine under the instruction of the ground command and was ready to return.

Sitting in the passenger seat, Nie Han imitated the voice of the flight attendant while checking the operation of the power supply components.

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

"I know, you don't need to remind me." Lu Zhou said with a smile, giving a thumbs up to the two of them, "Come on, I'll leave it to you to return."

He was in a pretty good mood at the moment.

This time, God was overdone.

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

Even if it is just for the 50,000 free experience, the cost of this test flight is not a loss.

Nie Yun turned his head and forced a smile, but his palms were already sweating.

The difficulty of returning is no less difficult than that of launching.

Although the return strategy of the auspicious spacecraft is theoretically much safer than that of general re-entry spacecraft, no one can guarantee that there will be no accidents. After all, it was the first time for him and the Auspicious to fly so high...

"Professor, can you promise me something?"

Lu Zhou: "What's the matter?"

"If this time I return safely..."

"Stop!" Lu Zhou hurriedly raised his hand, interrupting Nie Yun's half-sentence, "Don't rush to set up the flag right now, I'll promise you everything when it's on the ground."

Just don't overdo it.

Don't urge marriage.

However, Nie Yun did not appreciate it.

Seeing that Lu Zhou was obviously perfunctory, his hands suddenly left the console and said with a look of grief and indignation.

"No, I must say it now!"

Lu Zhou: "..."

MMP!

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

Sighing, Lu Zhou reluctantly spoke.

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

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

Hearing this, Lu Zhou immediately had a constipated expression.

how can that be!

He is still alive!

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

"The most I can promise is that this is the last time I will take your plane to the sky."

Nie Yun thought for a while, and nodded reluctantly.

"also!"

Anyway, just don't get on his plane.

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

For so many years in the army, this is the first time he has ever been so afraid of death.

"Okay bro, enough is enough for you!"

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

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

"The change of track is ready."

Returning to his usual composure and calm, Nie Yun closed his eyes and took a deep breath, then reopened his eyes.

"ignition!"

...

Whether it's a space shuttle or a space shuttle or any other manned spacecraft, returning from low-Earth orbit is always a technical task.

As the co-pilot, Nie Han first determined the "fuel" status of the auspicious ship. Among them, the remaining amount of deuterium-tritium mixed gas is quite sufficient, even if it is more than enough to go back and forth to the surface again, the only loss is the solid xenon in the working medium cabin, and the remaining amount is only 21%.

After all, there is no certain thrust to climb the gravity well. If you want to fly from the surface to the low-Earth orbit, you must increase the ejection amount of the working medium, and increase the thrust of the engine at the expense of a certain specific impulse.

However, if it is just a return flight, this working 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 to successfully complete the orbit change and entered the transition orbit from the operating orbit.

At the same time, in NASA's satellite control room, an exclamation sounded in front of the semi-arc console.

"Target begins to return."

"May the Pacific be their home," Aiden added viciously after staring at the green dot on the screen, "except for spacecraft, it's best not to leave whole bodies. "

The brows of several workers monitoring the movement of the spacecraft twitched fiercely.

For astronauts, this curse is too vicious.

Even for competitors...

Staring nervously at the green dot close to the dense boundary of the atmosphere, the engineer sitting in front of the console suddenly said.

"The trajectory of the Xiangyun number is abnormal..."

Aiden slammed his hands on the table, and said overjoyedly: "Did they fail?"

Could it be that God heard his prayer?

If they do fall in the Pacific, the fleet based in Guam will be happy to help salvage them.

"The way they return is different from what we know of..."

The excitement in his heart gradually subsided, and Aiden, who realized that the situation might be different from what he thought, gradually frowned.

"What's the meaning?"

"...There is only one possibility."

"what exactly is it?"

"Their fuel is still left..." Swallowed, the engineer said in a difficult tone with an unbelievable expression on his face, "And there is a lot left."
