"Demolition! Dismantle! Tear it all down——! The old cat waved his paws and shouted like the director of the demolition and relocation office, "Shantytown reconstruction!" Leave nothing behind! ”

“OK.” Mai Dong buried his head in the command compartment of the Eagle lander, with a screwdriver in his mouth, a tool bag hanging from his body, and a flashlight, "The fourth nut has been removed, and the number is MOYU-2A." ”

The girl held a flashlight in her arm and stuffed the screws floating in the air into the bag, the last screw on the protective cover, and when she removed the cover, she could see the bayonet connecting the seat to the floor. Mai Dong was removing the seats inside the command module of the Eagle lander, and in order to reduce the weight as much as possible, the old cat asked her to remove all the irrelevant things on the Eagle spacecraft.

There are a total of six seats in the command module of the lander, the two chairs in front of the center console belong to the commander and the co-pilot, and the remaining four chairs are the passenger seats.

Mai Dong only needs one chair, and the remaining five can be dismantled.

"Mr. Cat, where do you put the removed chair?" Mai Dong wiped the sweat from his forehead with a towel, "These seats are big and take up a lot of space. ”

"Put it in the Silence cabin first, find something to hold it in, and when you remove all the chairs, throw them outside." The old cat replied.

"Thrown out of the cabin?" Mai Dong asked, "Do you want to push it out directly?" ”

"It's too dangerous, you might hit the station's battery panels, and we're going to have to use our super arms to push them far enough away when throwing garbage."

Mai Dong removed the seat and dragged it around through the ship's interface.

"If a chair is 20 kilograms, the mass of five chairs is 100 kilograms, and if rounded up, it is one ton." The old cat leaned back in his chair with a pen in his mouth, "This is a large number, and the total mass of the upgrade on the Eagle lander is only fifteen tons, which is reduced by one-fifteenth in this moment." ”

Tang Yue was too lazy to take care of the old cat's mustache, as long as it didn't round up so much when calculating.

"Once the demolition is complete, how much mass will the Eagle lander be able to lighten?" Tang Yue sat across the table and was writing "A Brief Examination of the Development of Modern Art Genres".

The old cat slid the mouse and rotated the upgraded structural model on the Eagle lander on the screen, "Everything that can be dismantled is dismantled, this is to reduce weight, but also for safety reasons, the spacecraft is bound to bear a great impact when landing, which is the same as a car rear-end collision, seat belts and airbags are not enough, we also have to remove all the parts that may threaten the safety of the occupants, otherwise a small plastic fragment in high speed is as lethal as a sharp knife." ”

The mouse marked the structure of the lander in red one by one, "Eighty percent of the mass of the Eagle spacecraft comes from its own structure, that is, this shell, this shell is the only barrier that can protect Miss Mai Dong in the harsh environment, except for this shell, everything else is unnecessary." ”

"Twelve tons?"

"Thirteen tons." The old cat said, "Plus that chair that weighs a ton if rounded." ”

"Control computers, life support systems, and the like, don't you have to keep them?"

"Not kept." The old cat shook his head, "It's useless to keep it, because the batteries and compressed gas cylinders must be removed, there is no power supply, any electronic products are bricks that add weight, and life support can only rely on Miss Mai Dong's extravehicular suit." ”

"The problem is that the extravehicular suit can't last too long, and its self-sustaining ability is too weak."

"Eight hours, as long as it lasts eight hours." The old cat said in a deep voice, "I tried my best to control the Orion spacecraft to fall within a radius of 30 kilometers from Kunlun Station, and then we dismantled the battery of Kunlun Station and drove the stray dog to save her. ”

Tang Yue stopped what he was doing, "The communication system can't be preserved, so isn't it a state of disconnection...... That's a lot of risk. ”

"The whole plan is very risky from start to finish, and losing contact is nothing." The old cat said, "The control and positioning during the landing process are handed over to the Orion computer, and I believe that it will work until the end, and the Eagle spacecraft will not have to do anything, just protect Miss Mai Dong." ”

Tang Yue let out a sigh of relief.

"When this plan is completed, we will probably have nothing left except Kunlun Station."

"This is the price of saving people, exchanging all the resources in your hands for the survival of another person, I told you how those pioneers did back then, and hundreds of tons of propellants and rockets in exchange for a small fraction." The old cat said, "The quality of life is much heavier than Orion plus the space station." ”

Mai Dong unloaded the second seat, her speed was very fast, her work efficiency was quite high, and her hands-on ability had been fully exercised during this time.

"Miss Mai Dong, you have to carefully check whether the parts are missing, and there can't be any loose parts in the command cabin, understand?"

Mai Dong dragged the seat into the Silence cabin, then turned to get into the interface, "Can't you leave anything behind?" ”

"Yes." The old cat nodded, "These will be serious safety hazards during the landing, and the lander will withstand severe impact in the final stage of landing, and a loose screw is as powerful as a pistol bullet." ”

"Okay, I see."

Mai Dong began to disassemble the third seat, according to the order given to her by the old cat, first remove the seat, then remove the lining, and finally dismantle the computer and control panel, in the extreme environment The buttons and switches on the control panel are potential killers that threaten the girl's life, Mai Dong had better disassemble the command cabin into an empty shell.

"Mr. Cat, what about the supplies?"

"Supplies?"

"There's still some food and fresh water on the space station, and these tomatoes and plants I planted, can they be brought down?"

"I'm afraid not." The old cat shook his head, "Miss Mai Dong, we must put your life safety first, and everything else will be postponed...... To be honest, even if we try our best, we may not be able to guarantee your safety, and carrying other things can greatly increase the uncertainty, I hope you understand. ”

Fresh water and food in the space station are not carriable, except for Mai Dong himself, the old cat is not ready to put any movable objects in the Eagle spacecraft, Orion 2 has extremely high requirements for attitude control when re-entering the atmosphere, and a slight deviation is the consequence of the ship's destruction and death, so the center of gravity of the spacecraft cannot be affected in any way.

The food and fresh water in the cargo hold can shake and disrupt the balance during the high-altitude landing.

At this time, if you can lose one kilogram, you will lose one kilogram.

"I understand."

"Hey, old cat, can we discuss this again, maybe we can find an opportunity." Tang Yue interjected, he knew that Mai Dong had a deep affection for those plants, and letting Mai Dong abandon the ship alone to escape was like letting a mother abandon her own child, "If it really doesn't work, Mai Dong can bring down the remaining seeds, you can't bring the plants and other things that have grown up, and the seeds can always be brought in the pocket of the spacesuit, and you can take them down and plant them." ”

"Hmm." Mai Dong nodded.

The old cat crossed the table and cast a helpless look, it took off its headphones, "Tang Yue, the safest way is to bring nothing." ”

"I know." Tang Yue also took off his headphones, "But plants are also precious life on earth, and it is a life to be able to save one more life, do you know what is the biggest insight when I stay on Mars for so long?" ”

"What is it?"

"I am no more noble than a tomato, our lives are equal." Tang Yue replied, "With the weight of a few grams of plant seeds, does it really have any big impact if you carry them in your pocket?" ”

The old cat stared at Tang Yue and gave in after a few seconds.

"Well, it really won't make a difference...... However, except for plant seeds, nothing else is allowed. ”8)
