Die on Mars

dismantle!

kick!

Smash it!

shoot!

Lao Mao's methods are always so crisp and clear, and hit people's hearts directly.

Tang Yue read the "Guidelines for Earthquake Resistance and Disaster Prevention of Kunlun Station" in his hand, and the first item was to dismantle the Kunlun Station.

"The complete Kunlun Station cannot withstand an earthquake. We cannot guarantee the airtightness of the bulkhead materials. Once they are torn, it will be very troublesome to repair them." Old Mao pointed to the dome above his head, "If the Kunlun Station loses Without air tightness, it’s hard to say how much longer we can hold on.”

"I think it's not just Kunlun Station that will be torn apart, but also us."

Tang Yue could not imagine what kind of disaster an earthquake with a magnitude of 17 on the Richter scale would be. He had never heard of a magnitude 17 on the Richter scale in his life. If such a strong earthquake happened on the earth, it would probably tear the earth apart. The Eurasian continental plate is split, and the Arabian Peninsula can sink to the bottom of the sea.

Every two levels on the Richter scale increases the energy by a thousand times. The strongest earthquake recorded in human history was the 1960 Valvidia earthquake in Chile, measuring 9.5 on the Richter scale. This disaster left two million people dead. Returning home, dramatic geological changes even raised three brand new volcanoes, and seismic waves spanned the entire Pacific Ocean, causing huge tsunamis in Japan and the Philippine Islands on the west coast.

If the magnitude of the earthquake caused by the Tomcat-Tang-Mai comet hitting Mars exceeds 17 on the Richter scale, the energy released will be 1000000000000 times that of the Chilean earthquake.

Tang Yue doubted whether he could survive such a earth-shattering disaster. He was really frightened by this magnitude 17 earthquake.

"What are you thinking about?" The old cat looked at Tang Yue and waved his paw in front of his eyes, "What are you thinking about?"

"I'm wondering what a magnitude 17 earthquake is...if it happened on Earth, would it sink the Eurasian continent?"

"It's not that exaggerated. Seventeen on the Richter scale is just a rough calculation. In fact, the real earthquake intensity will definitely be smaller than this, because the energy of the earthquake comes from outside, not from the interior of the earth's crust itself." Old Mao said, "Comet impact When it reaches the surface, it itself has been torn apart by the gravity of Mars. There is a high probability that it will not be a complete individual, but will probably break into several pieces - when its internal gravity cannot resist the tidal force, The comet will fall apart."

"When the impact occurs, the energy carried by the comet will be released in various ways. Part of it is high-temperature thermal energy, which can melt all the deserts hundreds of kilometers around into glass, and a considerable part of the energy will be thrown high into the sky or even into the sky. The material in the orbit is taken away - Mars will have a halo after this collision, and the rest will propagate along the crust and cause strong earthquakes." Old Mao continued, "I estimate that the actual magnitude of the earthquake was about ten on the Richter scale. Between level five and level seventeen.”

"The difference between level fifteen and level seventeen is a thousand times." Tang Yue asked, "Can't you estimate it more accurately?"

"Sorry, there's really no way to accurately estimate this." Old Cat spread his hands, "Now we don't even know where it will land. Different geological conditions will lead to different consequences. Some places are hard and dense large basalts. , the soil in some places is soft, loose and porous, and the pain will be different if you kick it on a steel plate or a sponge."

"Strictly speaking, this thing cannot be accurately predicted because the ground beneath our feet is not uniform. The computer at Kunlun Station does not have this simulation capability. Unless you bring a supercomputer as big as the Pentagon, I can still try. Try... But based on my current observations, if it falls on the Sabah Highlands, I estimate that the magnitude should be 16. If it falls on the Arabian Highlands, the magnitude will be about 15.5. If it falls on Daser Tis Plateau...then there’s no need to estimate.”

"Why?"

"Then we're dead."

The Great Sertis Plateau is at the doorstep of the Ixi Plain. If the comet falls here, the entire Ixi Plain will be violently wiped off the map by the demon star.

The main materials in the nucleus of Comet Tomcat-Tang-Mai are ice and carbon dioxide, which will quickly evaporate during the collision, leaving a huge impact crater.

This will be the largest new crater on Mars this century.

"You don't have to worry about the magnitude of the earthquake. We don't have high-rise buildings anyway. No matter how big the earthquake is, as long as it is not big enough to overturn the earth's crust, we don't have to be afraid of it." The old cat suddenly revealed a feeling, "We are barefoot and are not afraid of wearing it." The "hooligan" temperament of the shoes comes, "When we lie down on the ground, it is like lying on a trampoline. It is strong and it is strong. The breeze blows on the hills and it is on its side. The bright moon shines on the river."

Tang Yue imagined such a scene in his mind: a man and a cat lying on the sand with two birds facing the sky, arms and legs spread out in a large shape, bumping up and down in the violent earthquake.

A bit gangster indeed.

"What about Kunlun Station? What should I do about Kunlun Station?"

"Put it away." The old cat got up and walked around the hall of Kunlun Station, reaching out to touch the inner wall. "Before the impact, break it into pieces. How did we put it up back then? How do we put it up now? Take it apart...and tear it down into a pile of frames and fabrics. What can an earthquake do to me no matter how powerful it is?"

Tang Yue looked up and looked around.

The roof of Kunlun Station is more than two meters high and is lined with pure white composite materials. The curved panels fit together to form the inner wall of the Kunlun Station hall.

The lining is screwed to a lightweight skeleton, the half-metal, half-carbon fiber frame that forms the basis of the Kunlun Station and is filled with foam insulation.

"The establishment of the assembly and assembly Kunlun station was the seventh and eighth landing missions. I heard them say that it took a long time."

"That's because I wasn't there at the time." Old Mao shrugged, "I can demolish this house into a pile of junk within sixteen hours... Don't look at me like that, in fact you can too, Kunlun Station itself is simple Modular design. In order to reduce your workload, the engineers on Earth did not design the one-click installation and one-click disassembly functions. Two or three of us can completely install the Kunlun Station within eight hours. Break into a shell.”

Tang Yue understood what Lao Mao meant.

"Wait until the earthquake passes and then reinstall it."

"That's the only way to do it." Old Mao nodded, "Otherwise, how can you withstand an earthquake of 16 or 17 magnitude? With your head?"

"During the time when the Kunlun station is being dismantled, I can only stay in the extravehicular suit, right?"

"Yes." Old Mao nodded, "Until the Kunlun Station is rebuilt, you can only wear an extravehicular suit. You must also wear it when charging and replenishing water and changing compressed gas bottles."

"What about eating?" Tang Yue suddenly remembered this incident.

Without Kunlun Station, how would he eat? You can't open the mask to eat, right? Besides, the mask of the extravehicular spacesuit cannot be opened.

"Will you starve to death if you don't eat for a day?" The old cat shook his ears. "You can replenish fresh water. Forget about eating. Just eat before you work."

Tang Yue's heart skipped a beat. Old Mao's tone sounded like "Let's have a good meal before we go on the road."

The next part of the "Kunlun Station Earthquake Disaster Prevention Guide" is personal protective measures.

This is what Lao Mao wrote:

When an impact occurs, use the terrain for protection as soon as possible. When there is a large bunker nearby, you should hide behind the bunker and lie down sideways, cross your hands on your chest, lower your head and close your eyes, draw in your abdomen and close your mouth, and straighten your legs and keep them together. .

Tang Yue felt that this description seemed familiar, as if he had seen it somewhere.

"Old cat."

"Um?"

"Do you know how to protect yourself when you're near a nuclear explosion?"

"When a nuclear explosion occurs, use the terrain for protection as soon as possible. When there is a large bunker nearby, you should hide behind the bunker and lie down horizontally, cross your hands on your chest, lower your head and close your eyes, draw in your abdomen and close your mouth, and straighten your legs. Let's get together." The old cat said without thinking.

Tang Yue patted the guide in his hand in front of Old Mao's eyes.

"What you copied was actually the "National Safety Education Manual for Primary and Secondary School Students"?"

The old cat looked away: ...I don't know anything, I'm just a pitiful, weak and helpless repeater.
