Die on Mars

"Mr. Cat? Mr. Cat, Mr. Cat, is that you? I can hear it! I heard it, I heard it!" Maidong's tone burst out with huge surprise, as if he had grasped a life-saving straw, "Mr. Cat, you guys Are you okay? Where is Mr. Tang Yue?"

"Everything is normal at Kunlun Station." Old Mao replied, "Tang Yue is also safe and sound."

"It scared me to death... It really scared me to death. You suddenly lost contact. There was no response no matter how many calls you made. What happened underneath?"

"Sandstorm." Old Cat said, "The weather interfered with communications. Fortunately, it didn't cause any damage. We have solved the problem."

Maidong breathed a sigh of relief.

"Miss Maidong, how is the situation over there?" Old Cat asked, "How many survival supplies do you have on hand? How many days are enough?"

"I had eaten the last piece of compressed biscuit fifteen minutes ago. I originally wanted to save it for tomorrow, but... I am so hungry that I can't sleep. There is nothing to eat on the space station now. Something." The girl whispered, as if she had done something wrong, "I... I also tried to chew on the thermal lining in the living cabin... Later I found that I couldn't chew it through at all..."

Ophiopogon japonicus's voice became smaller and smaller, and the old cat couldn't laugh or cry.

I bet this girl is a foodie, she even ate the food in the space station when she was hungry.

Tang Yue leaned on the door of the airlock and sat on the ground. He adjusted the brightness of the Mingguang armored headlamp to the maximum, but it still only illuminated the area one meter in front of him. Tang Yue felt as if he was in a On the dark seabed, the only place on earth that can resemble the current environment is the deep sea. As long as the depth exceeds two hundred meters, all light will be absorbed by the seawater, and further down you will be unable to see even your fingers.

Tang Yue thought to himself that if there was a diver on earth sitting on the bottom of the Pacific Ocean, with the dark water more than a thousand meters deep above his head, then the situation would be similar to his... just as dangerous, just as dark, and just as isolated.

But how could anyone sit so deep on the ocean floor? Human beings have the ability to land on Mars, but so far no one has been able to dive into such a deep seabed alone. Billions of tons of seawater will crush any living thing into a meat pie...except Spongebob.

Tang Yue was stunned.

He thought that if SpongeBob sat on the bottom of the sea, looking up at the sea alone, would he be waiting for someone?

"Tang Yue!" Old Cat's call came from the headset, "Adjust the antenna and fine-tune the signal reception direction to the east!"

Tang Yue stood up with great effort. He was really destined to do rough work. He was in tears just talking about it. Old Mao was sitting in Kunlun Station chatting with the little girl, while he stood outside wearing Mingguang Armor and blowing in the wind. While blowing the wind, he was thinking about sponges. Baby. I think it was the same when he was watching TV in his hometown when he was a child. It was always someone else who stayed in the room staring at the TV, and he always came out to spin his pennies.

The communication antenna stood at his feet, and the green indicator light flashed regularly. Tang Yue gently turned the tripod and made subtle adjustments to the direction of the antenna.

"How is it? Are you clear?"

"Turn east about two degrees...wait, fine-tune back and slow down a little, you've turned too far!"

"You can stand and talk without waist pain! Try performing millimeter-level operations in a sandstorm of thirty to forty meters per second!" Tang Yue counterattacked unceremoniously, "It's not easy for me to hold this thing steady! I If you don’t support the wall, just support this thing!”

"One and a half degrees! Just adjust the circumferential angle by one and a half degrees..." As the commander, the old cat obviously would not pay attention to Tang Yue's complaints. Its purpose was to keep the communication open and make demands using it, not to mention three times per second. Fourteen meters, even if the wind speed is three to four hundred meters per second, it should be one millimeter.

"What the hell is once and a half?" Tang Yue was going crazy. This old cat was becoming less and less talkative.

"One and a half degrees is one and one-half degrees, and half a degree is thirty arcminutes!"

"I know it's thirty arcminutes! But I have to tell you that my hand is not a goniometer! I can't give you an accurate unit like minutes!" Tang Yue shouted.

"How accurate can you be?"

"I can be precise to the extent of 'approximately', 'almost' and 'looks like'." Tang Yue replied.

"Then you can adjust the antenna eastward, almost at an angle that looks like 32 minutes and 15 seconds!"

Tang Yue:......

The Joint Space Station flies at a speed of 3.5 kilometers per second in low-Earth orbit. Its position changes all the time, so the antenna direction must also change. Tang Yue is a human motor and an equatorial mount. He has to adjust the direction of the antenna every once in a while to prevent the signal from being interfered with and attenuated by sandstorms.

The old cat is telling Maidong all the precautions for tomorrow's launch. It must hurry up. The current communication is only barely maintained and is very unstable. It is not known when it will be interrupted.

"Listen, Miss Maidong, at the end of the rendezvous between the Eagle spacecraft and the Joint Space Station, that is, the last one hundred meters of approach, the docking structure of the Eagle spacecraft and the space station will conduct precise positioning and relative posture assessment. This process It is fully automatic, but it is particularly important because it directly determines whether the docking can be successful. The circle fitting method is used on the space station for precise positioning..."

"Yeah, yeah, yeah."

"CRDS will capture the characteristics of the target aircraft during rendezvous. There is a target marker on the Eagle spacecraft. This marker is six LED lights. It will illuminate independently when approaching the space station. But you have to pay attention to the autonomous light-emitting marker. It is easily affected and interfered by ambient stray light, especially strong sunlight, so be careful to avoid direct sunlight.”

"Yeah, yeah, yeah."

"The docking port of the Eagle spacecraft is on the back of the fuselage. It is an allomorphic peripheral docking mechanism. That is to say, the docking port of the Eagle spacecraft is the same as that of the space station, except that one is positive and the other is reverse. The docking lock is designed to prevent reverse transmission. The docking mechanism will be locked only after the computer issues a locking command. After the docking is successful, you must ensure that there are no problems with the locking and air tightness..."

"Yeah, yeah, yeah."

"The entire rendezvous process, from long-distance guidance, short-distance guidance, to approach, approach and docking stages, must be completed by the space station itself. Originally, during the long-distance guidance stage, we could provide guidance on the surface, but It’s impossible to look at the weather now. The microwave radar on the space station was originally used for short-range guidance, but now you have to use it for full guidance..."

"Yeah, yeah, yeah."

The old cat spoke very quickly and told Ophiopogon japonicus everything he could think of.

"During rendezvous and docking, the two-way link between the Eagle spacecraft and the space station must be kept open."

"Yeah, yeah, yeah."

"After receiving the feedback signal from the space station, the Eagle spacecraft will start the rocket engine according to the distance and gradually slow down. The maximum speed during final docking cannot exceed five meters per second."

"Yeah, yeah, yeah."

The old cat was silent for a few seconds, "Ms. Maidong, you were um um um um the whole time, did you understand what I said?"

The girl looked innocent and confused.

"I can't understand it at all."

The old cat held his forehead.

"Then why do you keep humming?"

"Then...then I have to say something?"

The old cat groaned and covered his chest. He felt that he had been internally injured and his motor had a myocardial infarction.
