Die on Mars - Chapter 218

c218 Day 327 (4) Position of the Third Division

When Tang Yue got the calculation results, he was very excited, thinking that he had the handle of fate. Lao Mao once said that the outcome of the United Space Station was already doomed, but they couldn’t see it – but now Tang Yue saw it, and he calculated A very rough result was obtained, and there is hope in this result.

As long as there is hope, then he can work hard to make it a reality.

“Tang Yue, you and Mr. Cat are each more crazy than the other.” Maidong said, “It was very bold to use the Orion spacecraft as a lander before, but now you want to use the cargo spacecraft as a fighter jet.”

The implication is that you are too wasteful.

The Orion spacecraft and the Joint Space Station were lost in this way.

“If it gets out of control, it will be an irreversible situation…” Maidong expressed his worries.

“We have been doomed for a long time. Now we can live one more day and earn one more day.” Tang Yue waved his hand. To be honest, he cared more about Maidong’s life than the Tianzhou cargo spacecraft. If the latter could not land safely, the Tianzhou spacecraft would explode. Just fry it, since he doesn’t like lobster anyway.

Based on several estimated orbital altitudes of Maidong, it is inferred that the altitude of the Joint Space Station is continuing to decline, and the rate of decline is getting faster and faster. The simulation result of the workstation is that it dropped to a range of 100 kilometers to 110 kilometers on the seventh day. , the altitude fell below 100 kilometers on the eighth day, the orbit could remain above 90 kilometers on the ninth day, and it would fall below 80 kilometers on the tenth day.

This rate of decline is slower than Lao Mao expected. This is because the northern hemisphere has entered spring, and the position of Mars in its orbit has changed. The activity of the lower atmosphere has gradually intensified, the temperature of the upper atmosphere has dropped, and it has begun to sink. The edge of the atmosphere is closer than ever. Thin, causing less resistance to the space station.

But atmospheric activity is almost completely random and no one can accurately predict it.

On the tenth day, the Tianzhou 37 cargo spacecraft will arrive and dock with the space station at an altitude of about 80 kilometers.

Unfortunately, the distance estimated by the eye-jumping method is not very accurate. In such a difficult operation as docking, the entire plate will be smashed if there is even a slight difference. However, the data in Tang Yue’s hands may have a huge error of several kilometers, so the calculation needs to be more precise.

“Well – I have reached the limit of this step. Further steps will require more complex mathematical models… This is beyond my ability…” Tang Yue held the pen in his hand and stared at the paper for a long time. calculation, and then scratched his head. When he encountered a real hard problem, his nature as a scumbag with a non-major background was exposed.

He checked his calculations repeatedly to make sure there were no mistakes.

“I can try to be a little more precise. I should be able to do it with a decimal point. I think back then I scored 138 in mathematics and 96 in physics in the college entrance examination. The foundation is quite solid.” Tang Yue raised his pen again and frowned, ” The bottom should be… below…”

“Leave it to Old Cat now.”

The old cat came back after checking the landing site.

Tang Yue handed it the draft paper in his hand.

Old Mao took the manuscript paper, raised his eyebrows, and scanned it with narrowed eyes, “Is this the result of your busy work on the table in the past two days? You were so busy that you didn’t even eat well… The predicted orbit of the United Space Station… ”

The old cat suddenly laughed.

“Tang Yue, you are just an electrical engineer.”

“What’s wrong with the electrical engineer?” Tang Yue was very dissatisfied with Lao Mao’s tone, “Can’t electrical engineers be counted as such?”

“Yes, yes, of course, you can do it as long as the law prohibits it. Not only can you calculate this, you can also calculate the lifespan of the big black hole in the center of the Milky Way… Let me see, let me see.” Old Cat put on his headphones , pulled a chair over and sat down, crossed his legs, stared attentively, and began to examine Tang Yue’s calculations, “Let me see…”

Tang Yue was a little nervous, as if he had just handed in his homework and the teacher was correcting it.

He believed that his calculations were correct, but only Lao Mao’s admission could truly finalize his results and become a valid basis.

“How about it?”

The old cat was silent for a long time without speaking. It turned the draft paper in its hand over and over, and finally rolled up its eyes and glanced at Tang Yue. At this moment, it really looked like an old teacher correcting homework. .

“According to your calculations, by the tenth day, the United Space Station has fallen to an altitude of 80 kilometers.” Old Mao said in an inquiring tone, “At this time, you let Tianzhou come up, you know what this means ?”

“Know.”

“You know shit.” Old Cat rolled his eyes, “Imagine asking a fighter jet flying at hypersonic speed to open the cockpit cover during the flight and let the pilot climb into another plane not far away. Do you think this is… Is it Mission: Impossible? The man trapped in the space station is action veteran Tom Cruise?”

“The Tianzhou spacecraft is just a big steamed bun without any aerodynamic control surface. How do you accurately control it to dock with the space station in the atmosphere?”

“The United Space Station is such an irregular thing, how do you control its posture? What if its posture is too weird?”

“If there is a conflict between these two things, do you know what the consequences will be?”

Lao Mao’s questions were very sharp and he asked them one after another, leaving Tang Yue speechless and merciless.

“Your idea is too anti-human and anti-social, and the probability of failure is 99%.” Lao Mao finally commented on the paper while patting it.

Calculation is one thing, actual implementation is another.

“I… mine won’t work, but you can come up with a feasible plan.” Tang Yue was anxious, “What problem can be solved by finding faults?”

“This is my plan.” Old Cat returned the draft paper in his hand to its original owner.

Tang Yue was stunned.

“Your plan is actually the same as mine. I was originally going to tell you the detailed plan steps tomorrow, but since you figured it out yourself, there is no need for me to wait until tomorrow.” Old Cat’s serious face Suddenly he relaxed, “It’s just that your calculation results are too rough. This result cannot be used as a guide for the action plan. We still need more and more accurate data to improve it.”

“So this is feasible?” Tang Yue asked, “You just said that the chance of failure is 99%…”

“This is not a question of whether it is feasible or not.” Lao Mao shrugged, “If there are conditions, we will do it. If there are no conditions, we will create conditions to do it. Since the design allows it, then we will try to squeeze the performance limit of the Tianzhou spacecraft… Although it There is no consecration from the Patriarch, but the spirits of the chief masters in heaven will bless us.”

“We can set up three divisions. The chief engineer will ensure that the spacecraft program runs normally and completes the instructions. The chief designer will ensure that the spacecraft’s aerodynamic control is perfect and there will be no mistakes. The chief craftsman will ensure that the spacecraft body is strong enough and there will be no mistakes.” Old Mao continued. Said, “This is your strength, Tang Yue.”

“Can you handle the docking operation?”

“It can’t be done.” The old cat said simply.
