The old cat said this quite hardly, and seemed to be confident.

But Tang Yue was very uneasy, the old cat's plan was more unreliable than the other, and the other was more bizarre than the other, and it was already a whimsical method to let Orion II land vertically, and now the old cat claimed to let the Eagle lander tie the inflatable capsule into the atmosphere?

"I don't think there's a problem." Mai Dong was eating, and she rarely had time to rest.

Since the landing plan began, Mai Dong has become the busiest person, she is alone on the United Space Station, no one can ask for help, everything has to be done by herself, these days the girl's sleep time is getting shorter and shorter, and she has little time to take care of the plants in the space station, she always carries dry food and wrenches, and she nibbles when she is hungry.

The Joint Space Station has a separate galley, located in the Harmony service module, with a large dining table with its own heater, water gun and oven, which can seat six people in a circle, and all the utensils and plates are made of metal and held in place by a magnetic tabletop. When supplies are plentiful, crew members can heat up food in the kitchen and even fry steak and tuna meat.

But Mai Dong didn't need it, she sat in the chair, her feet held in place with straps, and only compressed biscuits, sandwiches, and tomatoes in front of her.

"Of course there won't be any problems." The old cat said, "As long as we tie it firmly enough, the thrust of the rocket is strong enough, and the descent speed is slow enough, the balloon will not fall off, do you know how to tie it most firmly?" ”

Tang Yue shook his head.

Mai Dong also shook his head.

The old cat smiled smugly.

"Look at you two little rookies, compared to your Captain Wang, it's really still far behind, Lao Wang is experienced, he knows how to tie it the strongest."

"What did the old king say?" Tang Yue and Mai Dong asked at the same time.

The old cat shook his ears and recalled.

"He said tortoiseshell binding."

Tang Yue cut the biscuits on the plate horizontally, then vertically, then horizontally, and then vertically again.

"No matter how much you cut it, the pickled cuttlefish-flavored biscuits will still be pickled cuttlefish-flavored after all." The old cat sat on the side, "It won't become the smell of braised pork." ”

Tang Yue sighed, for him, eating had become a burden.

Compressed biscuits have long been tired of eating, Tang Yue suspects that the taste buds on his tongue have been completely killed, so no matter what he eats, it tastes like chewing wax - there are so many compressed biscuits in Kunlun Station, Laotan sauerkraut flavor, braised beef flavor, fresh shrimp and fish plate noodles, salted cuttlefish flavor, he can't eat the difference.

If it weren't for the fact that he had to replenish enough carbohydrates every day, Tang Yue really didn't want to touch these things anymore.

"How much fresh water do we have?" Tang Yue threw the knife on the plate, and he decided to eat half a tomato first.

"One thousand and one hundred liters."

"A hundred liters have been consumed?" Tang Yue calculated, "On average, 0.36 liters of fresh water are lost per day, which is different from the previous estimate, I remember the old cat, you said that Kunlun Station loses 0.28 liters of fresh water per day." ”

"Obviously, the fresh water recovery situation at the Kunlun station is not as ideal as we imagined, and it is impossible to recycle every milliliter of wastewater in the presence of gravity." "In fact, the rate of fresh water loss at the Kunlun station is more than 0.36 liters per Martian day, and we currently have 1,100 liters of fresh water, thanks to the replenishment of the descending stage of the Eagle spacecraft, otherwise we would have lost more water." ”

"Then if the loss continues at this rate, the fresh water in Kunlun Station can hold on ...... longer."

"Three thousand Martian days."

"When I counted half a year ago, there were still 4,000 Martian days, but only more than 200 days have passed, and there are only 3,000 Martian days left." Tang Yue muttered, "This water level drop is not a uniform motion, this is a uniform acceleration motion." ”

"It's a uniform acceleration in itself." The old cat turned his head, "The efficiency of the fresh water recycling system will gradually decrease over time, and you have to be glad that the water recycling device is very reliable and has not had any problems so far...... If it fails badly, the situation will be worse than the damage to the OGS's temperature-controlled processor. ”

"What is the worst failure of the water recycling system?" Tang Yue asked.

"The tank is broken." The old cat said, "1,100 litres of fresh water are all lost. ”

"Then I can die."

Tang Yue finished gnawing on the tomato in his hand, I don't know when he no longer shy away from the word "death", from a certain point of view, Tang Yue is fighting for his life with God, and he will earn one day if he lives more.

"If we can successfully carry out Miss Mai Dong, then the fresh water consumption in the Kunlun station will be doubled, and I estimate that the current fresh water retention in the Kunlun station can last for a maximum of 1,000 Martian days." The old cat calculated, "If there is no comet Tomcat-Tang-Mai." ”

"yes, if it weren't for that comet, we would still be able to live a thousand days on Mars." Tang Yue threw the cookie pieces into his mouth, "Didn't you say that the comet crashed down, trillions of tons of dust filled the atmosphere, and the entire Mars would be dark?" The solar panels at Kunlun Station are useless, right? What do we generate electricity from? Generate electricity with love? ”

"Let's rely on the pedals of the bicycle to pedal the generator." The old cat points to the gym bike in the corner with his toes.

The bicycle in Kunlun Station is used for fitness, Tang Yue has to ride five kilometers on it every day to ensure that his muscles and bones will not atrophy and decline, such fitness equipment is available on the Kunlun Station Joint Space Station, the main purpose is to ensure the health of the team members.

But later, an engineer surnamed Tang felt that the team members were pedaling on the bicycle every day, and it was a pity that this energy was wasted, so he installed a self-made generator on the bicycle pedal axle, and the energy output of a strong muscular man like Lao Wang could light up the light bulb in Kunlun Station.

"How much power does that thing have?" Tang Yue was dumbfounded, "Can you use it to generate electricity for wool?" Am I going to have to sit on it 24 hours a day? ”

"You're an electrical mechanical engineer, how can these little problems be difficult for you?" The old cat showed full confidence in Tang Yue, "Make a gear set, and then make a few parallel generator sets or something, as long as there is enough torque, the speed is not a problem!" ”

The old cat described to Tang Yue his future life: after the comet hit Mars, the whole world was pitch black, the wind roared, and there was no daylight.

The friction between the rotor and the brushes of the generator burst out of sparks, outputting a steady stream of current to charge the battery of Kunlun Station, while Lao Mao and Miss Mai Dong sat under the warm light, blowing the soft heating of OGS, and drinking tea comfortably.

"Are you going to use me like a cow or a horse......

Tang Yue remembered the hamster scurrying in the wheel.

"How can you be a cow?" The old cat waved his hand and said in an uplifting tone, "You are electricity, you are light, and you are the only myth!" You're our only Superstar! ”8)
