Die on Mars

"Old cat——!"

Tang Yue howled in the channel again.

"What's wrong?" Old Cat stood on the ramp of the Eagle spacecraft, frowning.

"Damn, this box is too big and heavy. I can't move it alone!" Tang Yue groaned and tried his best.

He was wearing the Mingguang Armor at Kunlun Station and had to move boxes. This was an impossible task. He couldn't even bend down while wearing the Mingguang Armor's bulky extravehicular suit.

"Find your own solution!"

"Old Cat, you are really not a fucking human being." Tang Yue scolded angrily.

"I'm not a human being." The old cat shrugged, then checked the lander's rocket, "I'm just a cat."

Tang Yue was helpless. To be honest, Lao Mao might not have time to help him. The Eagle spacecraft would be launched soon, and both Tang Yue and Lao Mao were very busy.

Tang Yue needed to transport supplies, and Lao Mao needed to inspect the spacecraft. They had a mountain of work on their hands and couldn't spare any time to help each other.

Short of manpower, they must race against time.

Tang Yue bent down and tried to move the box for the third time but failed. He had to take off his Mingguang Armor to do it again.

"Old cat!"

"What's wrong with you?"

"I can't move anything while wearing Mingguang Armor!" Tang Yue panted, "Help me take this thing off."

"Take it off yourself!"

The Mingguang armored extravehicular suit is designed so that it cannot be put on and taken off by one person, because the openings and life support system of this space suit are at the back. A second person must be present to help when putting on and taking off the suit.

But just in case, Kunlun Station has also designed a self-service extravehicular suit donning and doffing system... This thing is installed on the wall and looks like a metal claw. When he needs to take off his extravehicular suit, Tang Yue only needs to lean against it. , let the claws jam the life support system behind it, and the turtle shell can be removed.

"Mingguang Armor is out of program, level one preparation, turtle shell locked!" Tang Yue grunted with a serious face.

There was a "click" and the indicator light came on, indicating that the life support system had been jammed and locked.

"Mingguang Armor is out of program, Level 2 preparation, turtle shell is unloaded!"

Tang Yue pressed the button on his wrist to interrupt the connection between the life support system and the Mingguang Armor, then untied the straps and completely got rid of the huge box.

"Start disengaging!"

Tang Yueping lay on the floor, and then began to squirm slowly, his buttocks slowly arched.

This is not Tang Yue letting himself go and kissing the ground when no one is around. This is his usual escape posture... Since the entrance and exit of the Mingguang Armor is behind his back, Tang Yue finally felt that after repeatedly trying various escape postures, The butt first method is the most convenient.

The old cat said that this posture is quite like a bastard coming out of his shell.

Tang Yue would never dare to do this while the rest of the scientific expedition team were still there.

The other four old gay guys are here and sneer. You lie on the floor and arch your butt?

Have you thought about the consequences?

Tang Yue emerged from the Mingguang Armor, and suddenly he was as light as a swallow. He jumped up and turned around to move the box. He opened the door of the airlock, carried the box to the end of the airlock, and then returned to the hall to put on the Mingguang Armor.

He cannot directly open the outer hatch of the airlock, otherwise the loss of pressure will kill him in an instant.

Tang Yue had to put on and take off the Mingguang Armor every time, which was very troublesome.

But there was nothing we could do about it. Once we left Kunlun Station, we had to put on the extravehicular suit. This must not be done carelessly, otherwise Tang Yue would die before the supplies were delivered.

A few minutes later, Tang Yue came back wearing Mingguang Armor. He opened the outer hatch of the airlock and struggled to push the box out of Kunlun Station.

Old Cat is inspecting the second-stage rocket in the ascent stage of the Eagle spacecraft.

There are two stages of rockets in the ascent stage. The first stage rocket is two Raptor 3C liquid oxygen methane engines. The function of this stage rocket is to push the Eagle spacecraft away from the surface of Mars and into the LMO orbit. It will be exhausted after working for 200 seconds. propellant, separated from the payload on top.

The second stage rocket, which is the upper stage rocket, is a Russian-made RD-0172 engine. Its role is safety and maneuverable orbit change.

In order to reduce the weight as much as possible, the lander does not have an escape tower, so only this stage of the engine can provide safety guarantee for the command module. Once there is a problem with the Eagle spacecraft during launch, the upper stage rocket can immediately bring Escape from the command module.

If the Eagle spacecraft can successfully lift off, the role of the upper-stage rocket is to perform maneuverable orbit changes to assist the command module in rendezvous and docking with the Joint Space Station.

In a two-stage rocket, there can be no problems with either stage.

If there is a problem with the first stage rocket, the Eagle spacecraft will hit the ground.

If there is a problem with the upper-stage rocket, the Eagle spacecraft will not be able to successfully dock with the Joint Space Station and become space junk floating in the low-Earth orbit of Mars.

Old cats must be careful.

Fortunately, the liquid rocket engine itself is not a particularly complicated structure. In essence, the basic structure of a liquid rocket is a pump, a combustion chamber, and a nozzle. The pump sends propellant into the combustion chamber, and the propellant is in the combustion chamber. It is ignited in the middle and finally sprayed out through the nozzle. It is simple and crude, and it is a disposable thing, so old cats can still play with it.

But if what is in front of it at this moment is an aero engine used on an aircraft, such as a complex and sophisticated thing like the F119 turbofan engine, with several stages of compressors and several stages of turbines, then the old cat will be scratched.

It's not an engine designer after all.

"Tang Yue!" Old Cat shouted.

"What's wrong?" Tang Yue pushed the trolley towards the lander and raised his head.

"I'm short of a No. 7 penta wrench." Old Cat stood on the gangway, looking down at Tang Yue on the ground not far away, "Bring it to me!"

Tang Yue was stunned and thought to himself, Old Cat, are you going to ask me for help one day?

You are finally in my hands.

Tang Yue sneered twice in his heart.

"Get it yourself!" He cleared his throat and said righteously, "Don't you see what I'm busy with? How can I find the time to help you get a wrench?"

"You won't take it?"

"No!" Tang Yuexin said, "I can't cure you anymore?"

"Are you sure you don't want to take it?"

"Sure!" Tang Yue said harshly, "If I help you get the wrench, I will pronounce your name backwards from now on!"

"Okay." The old cat nodded and patted his paws, "If you don't want to take it, don't take it. I have no objection, but without this wrench, I can't complete the next work. When will you help me get the wrench?" Come here, I’ll continue anytime.”

Tang Yue was stunned.

"I am not responsible for delaying the launch timing." The old cat continued, "Now the life of the little girl above your head is in your hands. It's up to you."

"you!"

"What are you?"

"You're awesome."

Tang Yue pushed the car forward hard, then turned around and went back to get the wrench.

"The wrench is in the second cabinet under the table! Note it's number seven!" Old Cat shouted behind him, "Yuetang!"
