The third day was the same pain!!

Little sister B is not as talented as Li Li, according to the book, read the place where there is a word in the book, and when the book says to watch the video or picture, she will put the video away.

What Earth to Mars takes 16 months, Mars orbit calculation method, the Earth to Mars was originally a dynamic distance, now it is only three months at the near point, and if it flies at the far point, it will take decades to arrive. Methods for measuring the relative position of the landing site on Mars, methods for geological soil sampling and analysis, methods for selecting camp sites.

In the back, Fang Wenjing has already entered the state of entering the left ear and leaving the right ear, and he remembers a flight time of three months in all four hours... What movies and games should you bring to play in the past three months? Damn, it's better to read the book yourself, and when you encounter a problem, just take the Pad out and check the fuck!

During lunch, she saw Li Li eating with two boys who looked like engineers, so she walked over and waved the plate and said, "Uncle, I want to eat with you!" ”

The two engineers looked at them with a confused expression, and Li Li had no choice but to say, "I'll go to you in the afternoon, I'm sorry, my sister's child." ”

The two little engineers hurriedly withdrew, and kept looking at Fang Wenjing, who was wearing work clothes.

"What's wrong?" Li Li asked while eating fried bananas.

"The two women upstairs have no educational talent at all, and all the information in the theoretical part is directly given to me and I can read it myself." Fang Wenjing said.

"Okay, what did you learn in the morning? Geology? ”

"Uh-huh."

"They are not geologists, so they don't have to go there in the afternoon. Come with me after eating. ”

"Oh?"

After eating, Li Li led Fang Wenjing to the 12th floor, and swiped his card into an office full of blackboards, bottles and cans, and some medium-sized machines.

"Xiao Zhang!" Li Li shouted as soon as he entered the door.

"Huh? Mr. Li? Is there something wrong? A young man in a white lab coat and a short, bespectacled woman straightened up from a noisy pile of machines.

"The new astronaut candidate, teach her about geological analysis methods and astrogeology. You have to teach her well, I'm going to test her when I go back! Li Li smiled.

"Okay, no problem!" Xiao Zhang said. "That's right, Mr. Li!" He suddenly screamed, startling all three people in the room.

"Huh?" Li Ligang's leg trembled in fright and shrank back.

"The Explorer ground probe has discovered a large gold mine beneath the surface of Mars! I mentioned it in my briefing on Monday. Have you seen it? ”

"Oh? I didn't pay attention. When was this? What about the current situation? Is the geographical location and mining conditions met? ”

"Wow, boss, you don't read my briefing! What happened last Friday! Nasa immediately changed their communication encryption method, and our wire report was interrupted. Then the geographical location is there, of course, the mining conditions are also met, and everything that can be detected by the ground detector is easy to collect. ”

"Well, my my, you asked the assistant to mark all the resource points on Mars now with information on the map and send me a copy."

"Okay, do it right away." Xiao Zhang raised his head at the glasses woman beside him.

"Miao Miao, come out for a while." Li Lidao.

I am most afraid of the sudden silence of the air.

Li Li had to snap his fingers next to Fang Wenjing's head in a daze, "Wang Simiao? What do you think? Come out with your uncle. ”

it! Are you calling me?! Fang Wenjing woke up like a dream, and walked outside with him.

"Hey, can you be more professional, nephew Queen Simiao?"

"Yes, you suddenly changed the words and didn't react."

"Be smart. The discovery of gold will definitely accelerate the US plan to colonize Mars. You have to go faster. ”

"...............," Fang Wenjing said, "You're a tease sent by the monkey, right?" He looked at Li Li with an expression.

"You trust my military judgment, they changed the encryption technology to show that the Ministry of Defense was involved. As soon as the Ministry of Defense participates, there will definitely be military operations at the national level. ”

"Oh." Fang Wenjing paused. "Excuse me, you're busy, I'm back to work." turned around and left, and was pulled back by Li Li.

"Holy! Tap Boss! Fang Wenjing was pulled 270 degrees in a flash.

"Where are you going?" Li Lidao.

"Didn't you say that the United States is going to launch a military operation against Mars! Then don't you have to send an army too? Oh no, my country's foreign policy is to make a fortune quietly and can't afford to resolve conflicts peacefully, so let's not go?? Lest people think we're going to fight and shoot us down? ”

"No, I don't know if my country will send troops, but you have to hurry up and send you two more soldiers."

"How tight is it? Two are pronouns, right? Referring to some? A platoon? ”

"Seven days at the earliest and ten days at the latest, we still have to prepare for launch and ignition tests. I have two soldiers in my hands who can be absolutely obedient to you, and that's enough. ”

"How obedient? It's hard to say if you're out! What should I do? What should I do if I'm pregnant and want to have a baby? ”

"No, I'll talk to you in detail in the evening in a small class, so let's go to your geology class first."

"Damn, why are you talking to me so much irritating remarks and expecting me to be able to go to geology class??"

"If you don't get in, you'll die on Mars, let's do it. Your life is on the horizon for these last few days of class. ”

"I'm not doing it, I'm not going to do it!"

"If I say this again, I will promise to imprison you for life, no internet, no sweets, no books, no sound, you can't survive, you can't die." This was the first time Li Li threatened Fang Wenjing, Fang Wenjing was frightened by his demeanor and tone, she believed that dogs that bite people don't bark, she felt that Li Li was fully capable of doing what he said, muted, and walked back to the address office with a cold sweat.

"Teacher Zhang, let's start the class......"

"Okay, little sister, what do you call it?"

“.... Wang Simiao. ”

"OK, just call me Xiao Zhang. I'll teach you how to analyze the ingredients directly, and go straight to the dry goods! Right. ”

"Do you have any courseware?"

"Well, yes, we still have to get it done."

"Hmm."

"The traditional measurement methods mainly test the following items: pH value, organic matter content, total nitrogen and inorganic nitrogen content, nitrate nitrogen (NO3-N), total phosphorus and available phosphorus, total potassium and available potassium, as well as soil conductivity, water and soil trace elements.

Traditional measurement methods include chemical analysis methods, photoelectric color separation methods, and indirect soil conductivity determination methods, but in recent years, we have used near-infrared spectroscopy analysis methods. ”

"Well, now one instrument can basically do it. It's the spectrometer in front of you. ”

“...”

"Put the soil that needs to be tested in this way, and then, press here to light, the light will be scattered by the soil and the spectrum will be fed into the computer, and then the computer will compare and model the soil composition, which is quite simple." Zhang fiddled with a machine in front of him.

"It seems to be quite simple, so what are the main ingredients to look for?"

"We mainly look for organic matter, but this seems unlikely, so we look for nitrogen and phosphorus in the soil, which are relatively versatile fertilizers and industrial raw materials, and basically more crops can be grown in that area."

"OK, understood, then the class here is over?"

"You can try it."

Fang Wenjing filled some soil in a slot and poured it on the position pointed by Xiao Zhang, pressed the button, and saw a messy spectrum appear on the computer, and then a number of clear spectrums appeared, and then there were component indices under each spectrum.

"Yo, is this a Fourier transformation?"

"Yo, do you know about the Fourier transformation? Yes. (Note: The Fourier transform is a set of formulas used to deal with spectral superposition and inverse superposition)

"That's OK?"

"Okay, I'll send you other information about the geological characteristics of Mars. If you're interested, see for yourself. ”

"Aren't you going to teach me how to fix your broken machine?"

"Hahaha, this is too complicated, you won't be able to teach it, if it's broken, I'll give you a remote call to the ground."

Mom, I've finally met a normal person! This is the scientific attitude of scientists! Not... So what if the communication equipment fails... It seems that the most important thing is to learn this.

"Okay, I'll get a copy of the courseware."

"Okay, Wang—thinking thoughts? What second? ”

"Uh, you send it to Mr. Li and let Mr. Li send it to me, right? I don't have an internal message account yet, I just came here today. Fang Wenjing then remembered that she was not called Wang Simiao, damn, every time you tell a lie, you always have to tell ten more lies afterwards to fulfill this lie, why don't you tell the truth directly.

After Fang Wenjing exited, he opened the Pad and said to Li Li, "It's over, looking for you." After looking at the time, only half an hour had passed, and I thought: Just like at work, the engineering man is really good at talking and practical.

Li Li: "Go to the simulation room on the 7th floor to simulate the rocket control by yourself, I have something to do." ”

At this moment, Fang Wenjing has accepted her predetermined fate and began to work hard to drive herself in order to go to Mars. She went to the 7th floor and swiped her card into the simulation room, where a 1-to-1 size operation room was made.

After pressing the power button, the computer on the console in front of me started up, and the screen displayed: "Welcome to Rocket Driving Simulator 1.0, please select the project you want to simulate." 1. Arrow body control, 2. Lightsail control, 3. Manual landing guide. She selected 1, and the menu popped up "1, arrow body control in flight, 2, arrow body control after landing." ", selected 1, "The control of the arrow body in flight is mainly used to avoid meteorites and meteors, the normal turning speed of the arrow body is 10 degrees per second, the sideways speed is 20 degrees per second, the adjustment of the head is mainly used to dodge the damage to the arrow body, and the sideways body is mainly used to avoid the damage to the light sail." Under normal circumstances, locking obstacles can automatically dodge ......"

Fang Wenjing felt like playing a simulation game, and learned it seriously, she kept giving herself psychological hints: "I can do it, it's not difficult, it's not as difficult as high math, it's not programming it's difficult, and it's not as difficult as EVE......."

When Li Li came to look for her in the evening, she had already made the final manual landing.

"Didn't eat?" Li Li asked.

"Yes." She said.

"I saw that you didn't go out when you came in, and I brought you something to eat." Li Lidao. Pull out a cookie and a toothpaste.

"Thanks, just hungry." She tore open the biscuit and ate it, looking at the package that said, "Ten years of shelf life?" ”

"It depends, like anything, some are bad in less than 10 years, some are still edible in 20 years."

"What is this toothpaste?"

"It's gelatinous water."

"How did I do it?"

"Chemistry. Don't ask me, I don't understand. ”

"You know what?"

"Military. Politics. Engineering. Computer. ”

"...... you?" Fang Wenjing swallowed the last bite of the biscuit.

"How?"

"Yes, you can. This cookie is so delicious. Fang Wenjing.

"This is your main dry food in the future."

"Wow, I'll die if I eat this at every meal."

"If you have the opportunity to build a dome environment, you can hatch the animals yourself. I'll give you some frozen fertilized eggs, which are poultry's. ”

"Ahem, building a dome sounds heavy ,,,?"

"It's not going to be heavy, you put the bracket up, and then the reinforcement and sealing have machines to help you."

"Okay, learn to build a house tomorrow?"

"Okay, see you at eight."

“OK。”

That night, Fang Wenjing learned to manually land until 11 o'clock in the evening. After everything is done, go back to the house to rest. The next day, she got up at six o'clock and went to the seventh floor to review the previous day's operations. Li Li came to the simulation room at eight o'clock and brought her breakfast.

The two of them went to the engineering department on the second floor, entrusted her to an engineer and left.

This engineer named Xiao Liu is very thin, and Fang Wenjing is also very thin, and the two hit it off at first sight.

Xiao Liu: "Do you know a toy, it's a ball?" He pulled out a colorful ball. But if you shake it off, it will become a big ball. With that, he shook it, and the solid ball in his hand unfolded into a hollow ball supported by a large plastic pull ring.

Fang Wenjing: "..... Now I know. ”

Xiao Liu: "It's the same with setting up a camp in space. The standard ratio of our bracket is 1 meter 3 apiece, light material, only 50 grams per piece, according to the single room, double room, 4 rooms, 8 rooms, 13 rooms on the manual with the connector splicing, directly to the ground throw, the connector will automatically open the adjacent bracket, and then cover it with a magnetic cloth. There are strong magnets on the bracket to hold the magnetic cloth. Basically, it takes about 2-4 hours to set up a campsite. ”

"I've heard that there are often big storms on Mars. This camp will be blown away then, right? ”

"After each build, the camp is fixed in the ground with rivets. That's it. Xiao Liu lifted a large iron nail one meter long.

...... "Fang Wenjing." How do I nail this, do you have to swing the hammer 3 meters high! Am I going to stand on a table and nail it! Hahaha,, you made me laugh. ”

"This is also electric, as soon as you twist here" Xiao Liu twisted the tail, and the head of the nail began to rotate. "You see, bring your own electric drill, and you can get in with a little effort in the back."

“……”

"Also, the best thing to do when the storm comes is to put the cloth away and put it back on when the storm is over."

"That's a lot of trouble!"

"Well, it's better to build an underground base." Xiao Liu said.

"You didn't say it sooner! Then why did I take the time to learn this scaffold! Fang Wenjing shouted.

"You'd better use a bracket for the underground base, do you want to live directly on the earth? There may be bugs. Xiao Liu said.

"How is it possible, doesn't it mean that there is no life on Mars?" Fang Wenjing said.

"One, that's not necessarily, and second, you have to close the camp to lock in the gas composition, and there is no oxygen in the Martian atmosphere." Xiao Liu said.

"Oh yes, I forgot about it."

"So you have to live in a confined space, whether it's underground or above." Xiao Liu said.

"Hmm."

"Here, I'll teach you how to use this rig."

“………”

"What's the matter, what's that look on your face?"

"I feel like I've come to New Oriental."

"Ahh Hahaha drilling rigs are easy to drive, much simpler than excavators and forklifts. ”

“………”
