In the few seconds when Tang Yue was stunned, the light outside the porthole dimmed, like a huge pitch-black curtain covering his head, and the sunlight disappeared immediately, Tang Yue, a child born and raised in a southern city, had never seen a sandstorm in his life.

Not to mention the sandstorms on Mars.

Tang Yue was dumbfounded for a moment.

Is this the end of the world?

The next second, the howling wind came to the face, and the lander was immediately engulfed.

Although Tang Yue and the old cat were in the command module, they were still involuntarily frightened, the sand and gravel swept by the wind scraped on the outer wall of the lander, the floor of the command module was trembling slightly, and I don't know what parts outside the spacecraft were blown and were rattling.

The Eagle is a masterpiece of ergonomics and materials science, but it is like a shaky building with broken planks in the midst of a storm, as if the roof will be torn off in the next moment.

"Mr. Tang Yue! Mr. Tang Yue...... You can hear ......."

A violent murmur of electricity surged up from the headphones, and Mai Dong's voice was drowned out.

"Mai Dong? Mai Dong! ”

Communication was interrupted.

"Hell!"

Tang Yue held the dashboard with one hand, leaned back on the chair to fix himself, and the old cat was a meter away, it was tightly attached to the inner wall, sitting on the floor, one paw clawing at the seat belt.

It was so dark outside the porthole that he couldn't see his fingers, the lander seemed to be thrown into deep water in an instant, and the roaring outside was not the air flow but the water flow, Tang Yue never knew that the sandstorm could be like this, covering the sky and the sun without seeing the sun, as a southerner, his imagination of the sandstorm was the sand flying in the sky.

The only light source in the command cabin was the light above Tang Yue's head, and Tang Yue crawled over to grab the old cat.

"Sandstorm." The old cat said, "It's a sandstorm!" ”

"Why wasn't there an early warning?" Tang Yue asked.

"The earth is gone." The old cat replied, "Who gave you the warning?" ”

Tang Yue sat on the floor, leaning on the porthole and looking out, it was pitch black outside, but the weather was still sunny just a few minutes ago.

"Will the lander be blown over?"

"No, it won't." The old cat shook his head, "It's okay if the wind speed is twice as big, the atmosphere on Mars is very thin and very low-density, and the force on the lander is actually very small, and it won't blow the lander down like in a certain movie." ”

It climbed into the commander's seat and turned on the monitoring system on the main console with a quick movement, and the blue numbers on the screen began to jump.

"The wind speed is ...... right now Thirty-two meters per second, and still rising. ”

Tang Yue got up and stood behind the old cat's chair, "What is the concept of this speed?" ”

"Equivalent to a Category 12 typhoon on Earth."

Tang Yue was taken aback.

Category 12 typhoon?

As a southerner, he has a deep impression of typhoons, which make landfall several times every summer, bringing a lot of rain and flooding, and then uprooting street trees and billboards on both sides of the road, causing billions of dollars in economic losses to the city.

Strictly speaking, a typhoon is a serious natural disaster, but it comes regularly every year, so the people of the south have become accustomed to it.

"The wind speed is now 39 meters per second." The old cat said in a solemn tone, "The speed is equivalent to a thirteen-level typhoon, and the wind speed is still slowly rising." ”

Tang Yue was frightened and looked around, for fear that the Eagle spaceship would be overturned by the strong wind.

"The wind speed is 44 meters per second, and it is a 14-level typhoon." The wind finally stabilized, and the old cat pushed the chair back and turned its head.

"Tang Yue, I'm afraid we will have to abort the launch plan."

The old cat and Tang Yue sat in the command cabin, neither of them spoke, and they were silent for a long time.

Tang Yue took off his extravehicular suit, this time he heard the wind whistling outside, it was as dark as thick ink outside the porthole, they were trapped in the lander, and no one dared to go out at will in this situation.

"We're going to have to stay here for the time being." The old cat said, "Now the visibility outside is less than three meters, and going out is a dead end." ”

"How long will a sandstorm last?" Tang Yue asked.

"I don't know." The old cat shook his head, "It may pass in a day or two, or it may last for a month or two, and if you are a little unlucky, it may take half a year." ”

"How did the previous expeditions deal with sandstorms? How did they deal with this thing? ”

"We can't solve it, we can't deal with sandstorms." The old cat replied, "Once the earth sends a warning, then the expedition team must stop all work, abandon all tasks, evacuate immediately, and return to the space station." ”

Tang Yue tugged at his hair vigorously and let out a long sigh.

Damn, what's this called?

The supplies have been packed and transported to the cargo hold, and we are waiting for the launch of the Eagle spacecraft tomorrow, everything is ready, only the east wind is owed.

It didn't turn out to be the east wind.

It's a typhoon.

The sandstorm that came out on the way disrupted all the plans, he and the old cat were trapped in the Eagle spaceship, Kunlun Station could not go back, and he lost contact with Mai Dong.

"Old cat...... Can the Eagle be launched in a storm? ”

The old cat was taken aback, "What are you thinking?" ”

"Can you?" Tang Yue's expression was so serious and solemn that it was terrifying, he grabbed the old cat's shoulders and stared at the latter's pair of cat eyes.

"You want to launch a lander in a sandstorm? Tang Yue, are you crazy? The wind is now 44 meters per second outside! And it's so dark that you can't see your fingers! Do you want to continue working in this situation? Don't you want to die? We have to abandon the launch plan. The old cat pointed out the window, and his tone became fierce, "Wait until the storm has passed before starting." ”

"Nope." Tang Yue shook his head, "We don't know when the storm will end, if this sandstorm doesn't stop until two months later, then we have to wait two months?" Mai Dong can't wait that long, I ask you, can the lander be launched in the storm? ”

The old cat stood there and gritted his teeth, "Theoretically, yes. ”

Tang Yue's eyes lit up.

"The Eagle spacecraft is designed to resist crosswinds of 50 meters per second, the density of the atmosphere on Mars is low, the force on the lander is not large, and the attitude can be controlled by relying on rocket engines." "But it's too risky, the Eagle has never been ......launched in such bad weather conditions before," said the old cat.

"That's it!"

Tang Yue interrupted the old cat, turned around and got into the Mingguang armor, "The Eagle spaceship lifted off as originally planned, and I will continue to carry supplies." ”

"Fuck your uncle! Don't you want to die? ”

The old cat grabbed him, pulled out a cable, tied one end to himself, and locked the other end around Mingguang Armor's waist.

"If you don't want to die...... Right after me. ”
