Nie Yun: "Can't a globe work?"
This altitude is quite satisfactory for manned spaceflight. Generally, manned spaceflight activities in low-Earth orbit are completed in areas below 400 kilometers, and Lu Zhou does not intend to let Xiangrui fly too far for its first flight.
Nie Yun, who was sitting next to her, nodded.
"The altitude is approaching the critical value and it is time to switch to flight mode."
I'll go away with my headache.
Standing next to the passenger seat, Lu Zhou looked at himself in the mirror.
"clear."
Knowing this in his heart, Nie Yun could only nod.
"This is the Xiangrui Hao..."
At this time, changing the flight plan at will will increase the mission risk.
Lu Zhou smiled and said, "After all, that is a conclusion drawn by others, and there is still a difference between the shock of seeing it with your own eyes."
"Continue sailing, the flight plan remains unchanged... but please make sure Professor Lu is safe."
MPP…
Just when Nie Yun hesitated to ask how to deal with it, Hou Guang continued.
Forget it, never mind.
After hesitating for a moment, Nie Yun reported the situation to the ground.
After a while, it was replaced by Hou Guang's voice.
Although the acceleration of this space vehicle, which is similar to an aerospace plane, is not very high. Strictly speaking, it only requires the protection of the spacesuit in the cabin during the return phase. However, considering that this is the first flight after all, even if sufficient preparations have been made, Be prepared, there are still many uncertainties.
The ground command was silent for a few seconds.
Almost at the moment he pressed the shutter, a light blue window faintly appeared in his field of vision.
Want a reason
For the sake of safety, everything must be strictly followed. This bulky space suit inside the cabin cannot be taken off until at least it enters orbit.
Speaking of which, this seemed to be the most expensive piece of clothing he had ever worn.
Thinking of this, Lu Zhou suddenly had an idea.
You can’t say that you just wanted to go up there and see the scenery, so you just took a ride on it? Although the scenery up here is really beautiful.
The arc light that lit up behind the Xiangrui began to weaken, changing from a shining dagger to a flickering candle. Finally, as the sound of "successful entry into orbit" reached his ears, the controllable fusion on the Xiangrui The engines shut down at the same time. As the power unit is shut down, the circuit in the cabin is also switched to the lithium-sulfur battery power supply system.
"Of course, I practiced it countless times at home."
only…
[Secondary mission: Overlooking the earth.]
Why don't you take a photo
It's a long journey from the surface to space.
"...Some accidents happened on our side."
However, although the mission description is not very central, the mission rewards are still quite delicious.
Although he couldn't hear it with his ears, Lu Zhou could feel in his heart at this moment, the cheers that echoed through the ground command headquarters, the national anthem that played in the launch center, and the pride that echoed in the hearts of all the personnel on site.
[Reward: 50,000 free experience points, one lucky draw opportunity. (Settlement after completion of the first phase)]
"Yeah... so beautiful."
[Explanation: Exploring science requires not only excellent vision, but also the courage to devote oneself to science!]
Uh, got it
Compared with the kind of extravehicular spacesuit that comes with its own power system and portable life support system, the indoor spacesuit is barely light, but it is not much better. As for the cost, it is naturally cheaper than an extravehicular spacesuit, probably around 10 million.
At this point, although it has not yet left the exosphere, the resistance of the air is already so weak that it can be ignored.
How should I explain it when I get back
Looking at the mission description, Lu Zhou shook his head and stuffed his phone back into his pocket.
It turned out that it had been planned a long time ago!
that is it
"I finally made it into orbit... Oh my god, this thing is quite easy to put on, but it's really not a hassle to take it off."
emmmm…
Finally, he released the lock from the passenger seat and connected it to the cabin environmental control and life-saving system. Lu Zhou, who took off his spacesuit in the cabin, slowly floated up from the seat. He was not very skilled but it was acceptable. The way it moved, it floated to the side of the space shuttle's porthole.
Nie Yun: “…”
Strictly speaking, altitudes from 100 kilometers (the upper limit of national airspace) to 2,000 kilometers are considered low-Earth orbit. The altitude of this test flight is based on the 419 kilometers of the International Space Station. The total flight time is about two hours. It is expected to stay in low-Earth orbit for 24 hours before returning to the surface.
Without Nie Yunduo's reminder, Lu Zhou had already walked to the side of the crew seat, opened the metal door connected to the bulkhead, and laboriously dragged out the bulky spacesuit inside.
The people at the ground command were probably in chaos at this moment.
The five engines behind him were at full power, like a retrograde meteor, dragging the blue arc of the Xiangrui as it continued to climb. The three people sitting in the cabin can clearly feel the increase in gravity, but the increase is so weak that once they get used to it, they can hardly feel it.
After ending the communication, Nie Yun took a deep breath, looked back at Lu Zhou who was packing the coffee cups into the storage box, and said a reminder.
[Requirements: Located at an altitude of 100-2000 kilometers, manually operate camera equipment to take photos of the Earth. (Limited to host completion)]
Nie Han: “…”
Also overlooking this blue planet, the shock brewing in Nie Han's heart was completely different from the emotions in the two men's hearts. What she sees is more based on beauty, or sensibility, than on the rational side.
According to the air pressure and temperature change curves, when the altitude reaches more than 20 kilometers, the density of the outside atmosphere will quickly decay to a very low value. At this time, it is no longer possible to rely on the wings to provide upward power. It needs to rely on engine thrust to fight gravity. The space shuttle will fly upward at a larger tilt angle.
"Professor Lu is here with us."
It took him a while to digest the shock in his heart before he sighed softly.
After all, wearing this thing makes it really difficult to operate a mobile phone, so I might as well forget it.
But after thinking about it, he finally gave up this plan.
This mission is really...
After reaching the airspace at an altitude of 20 kilometers, the output power of the engine behind the Xiangrui gradually increased. At the same time, the nose of the aircraft began to rise significantly, and it began to speed towards outer space along a trajectory that was almost tangent to the earth. And go...
"Okay, I know."
He had no obligation to explain this to anyone.
"I know."
Lu Zhou, who had finished putting on the various pipelines on the cabin's spacesuit and the cabin's environmental control and life-saving system, looked back at Nie Yun and raised his eyebrows.
Especially in a weightless environment...
It took her a long time, looking at the planet outside the porthole window, before she let out a sigh.
"… What a nice view."
…
After Lu Zhou thought about it for a moment, he finally shook his head and threw the thought to the back of his head.
After breaking through the 100-kilometer limit, the spacecraft has entered the warm layer from the mesosphere. About 60 kilometers further, you can reach the lowest altitude of orbiting the earth-160 kilometers orbit.
At this time, the crew can no longer move around in the spacecraft.
Seeing Lu Zhou's somewhat labored movements, Nie Yun hesitated and asked, "A space suit... can you wear it?"
It was as if he was about to devote himself to science.
"...Only by standing here can we most intuitively feel the fact that the earth is round."
Looking at the distant planet outside the window, Lu Zhou's pupils dilated slightly with a look of shock. The blue sea and thick clouds merged into one, and the lights of thousands of houses were like stars in the cold night, connecting with the morning glow that connected to the edge of the horizon.
Looking at the blue earth, Lu Zhou held his breath for two seconds at this beautiful scene, then took out his phone from his pocket and took a photo.
