Chapter 702 Overlooking the Earth

"This is the Auspicious..."

"...On our side, some accidents happened."

After hesitating for a while, Nie Yun still reported the situation to the ground.

"Professor Lu is here with us."

The ground command was silent for a few seconds.

After a while, it was Hou Guang's voice.

"Okay, I know."

uh, got it?

that is it?

Just when Nie Yun was hesitant to ask how to deal with it, Hou Guang continued.

"Continue sailing, the flight plan remains unchanged...but please make sure that Professor Lu is safe."

At this time, changing the flight plan arbitrarily will increase the mission risk.

Knowing this clearly in his heart, Nie Yun could only nod his head.

"clear."

After finishing the communication, Nie Yun took a deep breath, looked back at Lu Zhou who was packing the coffee cup into the storage box, and reminded him.

"The altitude is approaching the critical value, and the flight mode is about to be switched."

According to the pressure and temperature curve, when the altitude reaches more than 20 kilometers, the density of the outside atmosphere will rapidly decay to a relatively low value. At this time, it is no longer possible to rely on the wings to provide rising power, and it is necessary to rely on the thrust of the engine to resist gravity, and the space shuttle will fly upwards with a greater inclination angle.

At this point, the crew can't move around freely in the spacecraft.

"I know."

There was no need for Nie Yunduo to remind him, Lu Zhou had already walked to the side of the crew seat, opened the metal door connected to the bulkhead, and laboriously dragged the bulky spacesuit out of the cabin.

Seeing Lu Zhou's laborious movements, Nie Yun hesitated and asked, "A space suit... can you wear it?"

Skilled in the various pipelines on the spacesuit in the cabin and the environmental control and life protection system in the cabin, Lu Zhou, who has finished wearing it, looked back at Nie Yun and raised his eyebrows.

"Of course, I practice at home countless times."

Nie Yun: "..."

Nie Han: "..."

MPP...

It was already planned!

Although the acceleration of this kind of space vehicle similar to the space plane is not high, strictly speaking, the protection of the spacesuit in the cabin is only required in the return stage, but considering that it is the first flight after all, even if sufficient Prepare, there are still many uncertainties.

For the sake of safety, everything still has to be done in strict accordance with the procedure. This bulky spacesuit in the cabin cannot be taken off at least until it enters orbit.

Standing next to the passenger seat, Lu Zhou looked at himself in the mirror.

Compared with the extravehicular spacesuit with its own power system and portable life support system, the spacesuit in the cabin is barely light, but it is not much better. As for the cost, it is naturally cheaper than the extravehicular spacesuit, which is about 10 million.

Speaking of which, it seemed to be the most expensive piece of clothing he had ever worn.

Thinking of this, Lu Zhou suddenly came up with an idea.

Would you like to take a selfie?

But after thinking about it, he finally gave up on this plan.

After all, wearing this thing, it is really difficult to operate the mobile phone, so let's just forget it.

After reaching the airspace at an altitude of 20 kilometers, the output power of the engine behind the Xiangrui gradually increased, and at the same time, the nose of the aircraft began to rise significantly, and began to gallop toward outer space along a trajectory almost tangent to the earth. go...

...

From the surface to space is a long journey.

Strictly speaking, the altitude from 100 kilometers (the upper limit of the airspace of each country) to 2000 kilometers is counted as low-Earth orbit. The test flight altitude this time is based on the 419 kilometers of the International Space Station. The total flight time is about two hours. It is expected to return to the surface after staying in low-Earth orbit for 24 hours.

This height is quite satisfactory for manned spaceflight. Generally, manned spaceflight activities in low-Earth orbit will be completed in an area below 400 kilometers, and Lu Zhou does not intend to let the Xiangrui fly too far for the first flight.

The five engines behind it are fully powered, like a retrograde meteor, the Auspicious Auspicious, which is dragging the blue arc, continues to climb to the height. The three people sitting in the cabin can clearly feel the rise of gravity, but the rise is so weak that after getting used to it, they can hardly feel it.

Looking at the gradually receding planet outside the window, Lu Zhou's pupils slightly enlarged with a shocking expression. The azure blue sea and the thick clouds gathered together, and the lights of thousands of homes were like the stars in the cold night, connecting with the morning light that connected to the edge of the horizon.

It took him a while to digest the shock in his heart before he sighed softly.

"...Only standing here can you most intuitively feel the fact that the earth is round."

Nie Yun: "Can't the globe be enough?"

Lu Zhou smiled and said, "That is someone else's conclusion after all, and it's different from the shock that I saw with my own eyes."

Also overlooking this azure planet, the shock brewing in Nie Han's heart was completely different from the emotion in the hearts of the two men. What she sees is more based on beauty, or sensibility, than on the rational side.

It took a long time for her to let out a sigh when she looked at the planet outside the porthole.

"……What a nice view."

Nie Yun, who was sitting next to her, nodded.

"Yeah...so beautiful."

After breaking the 100-kilometer limit, the spacecraft has entered the warm layer from the mesosphere. About 60 kilometers forward, you can reach the lowest altitude of orbiting the earth - 160 kilometers orbit.

At this point, although it has not left the dissipation layer, the resistance of the air is so weak that it can be ignored.

The arc light behind the auspicious ship began to weaken, from a bright dagger to a flickering candle, and finally, with the sound of "successful entry" into his ears, the controllable fusion on the auspicious ship The engine shuts off at the same time. With the shutdown of the power unit, the in-cabin circuit was also switched to a lithium-sulfur battery-powered system.

Although he couldn't hear it with his ears, Lu Zhou could feel it in his heart at the moment, the cheers resounding in the ground command, the national anthem playing in the launch center, and the pride and pride that echoed in the hearts of all the people at the scene.

"Finally managed to get on track... Mom, this thing is fairly easy to put on, and it's really not a troublesome thing to take off."

Especially in a weightless environment...

Finally, the lock was released from the passenger seat and the connection with the cabin environmental control and life protection system. Lu Zhou, who took off the spacesuit in the cabin, slowly floated from the seat. The way of moving, floated to the side of the porthole of the space shuttle.

Looking at the blue earth, Lu Zhou held his breath for two seconds for this beautiful picture, then took out his phone from his pocket and took a photo.

Almost as soon as he pressed the shutter, a light blue window faintly appeared in the field of vision.

[Secondary mission: overlooking the earth. 】

[Explanation: Exploring science requires not only excellent vision, but also the courage to devote yourself to science! 】

[Requirements: At an altitude of 100-2000 kilometers, manually operate the camera equipment to take pictures of the earth. (Completed by the limited host)]

[Reward: 50,000 free experience points, a chance to draw a lottery. (Settlement after the completion of the first stage)]

This task is really...

Makes it seem like I'm about to devote myself to science.

Looking at the mission description, Lu Zhou shook his head and stuffed the phone back into his pocket.

However, although the mission description is not very central, the mission reward is still quite fragrant.

only……

At this moment, the people at the ground command are probably in a mess.

How should I explain it when I go back?

I can't say that I just want to go up and see the scenery, so I just hitchhike up? Although the scenery above is really beautiful.

hmmmm...

After thinking for a moment, Lu Zhou finally shook his head and threw the thought to the back of his head.

Forget it, take care of him.

He had no obligation to explain this to anyone.

Want a reason?

Go away with a headache.
