"Old cat——! Old Cat ——! ”

Tang Yue howled in the channel again.

"What's wrong again?" The old cat stood on the gangway of the Eagle ship, his brow furrowed.

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

He was wearing Mingguang armor in Kunlun Station, and he had to move boxes, which was an impossible task at all, and he couldn't even bend down in such a bloated cabin suit as Mingguang armor.

The old cat's face was full of black lines, "Figure it out yourself!" ”

"Old cat, you're not a fucking human!" Tang Yue scolded angrily.

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

Tang Yue was very helpless, to be honest, the old cat really didn't have time to help him, the Eagle spacecraft would soon be launched, and Tang Yue and the old cat were very busy.

Tang Yue needed to carry supplies, and the old cat needed to check the spaceship, and their own work was piled up, and they couldn't spare their hands to help each other.

With a shortage of manpower, they had to race against the clock.

Tang Yue bent down for the third time and tried to move the box but also failed, and he had to take off the Mingguang armor to do it again.

"Old Cat ——!"

"What's wrong with you?"

"I can't move anything in Mingguang armor!" Tang Yue panted, "Come and help me take this thing off." ”

"Take it off yourself!"

The Mingguang armor extravehicular suit is designed to be impossible for one person to put on and take off, because the opening and life support system of this spacesuit are behind the back, and a second person must be present to help when putting on and taking off.

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

"Mingguang armor is out of the program, first-level preparation, the turtle shell is locked!" Tang Yue hummed with a serious face.

There is a "click" and the indicator light is on, indicating that the life support system has been stuck and locked.

"Mingguang armor is out of the program, secondary preparation, turtle shell unloading!"

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

"Start disengaged!"

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

This is not Tang Yue's self-kissing and kissing the earth when no one is around, this is his usual detachment posture...... Since the entrance and exit of the Mingguang armor were behind him, Tang Yue finally felt that the way to go first was the most convenient after repeatedly trying various detachment postures.

The old cat said that this posture is quite like the style of the king out of the shell.

When the rest of the expedition team was still there, Tang Yue would never dare to do this.

The other four old GAY sneered and were present, you were lying on the floor arching your ass?

Have you thought about the consequences?

Tang Yue got out of the Mingguang armor, suddenly light as a swallow, jumped up and turned around to carry the box, he opened the hatch of the airlock room, carried the box to the end of the airlock room, and then returned to the hall to wear the Mingguang armor.

He couldn't open the outer hatch of the airlock directly, or the loss of pressure would kill him in an instant.

Every time Tang Yue had to put on and take off the Mingguang armor back and forth, it was very troublesome.

But this is no way, once you leave Kunlun Station, you must put on an extravehicular suit, this sloppiness must not be half a point, otherwise the materials have not been sent, Tang Yue himself will hang up first.

A few minutes later, Tang Yue returned in the Mingguang armor, he opened the outer hatch of the airlock chamber, and struggled to push the box out of Kunlun Station.

The old cat is inspecting the second stage rocket of the ascent stage of the Eagle spacecraft.

There are two stages of rockets in the ascent stage, the first stage is two Raptor 3C liquid oxygen methane engines, this stage of the rocket is to propel the Eagle spacecraft away from the surface of Mars and into low earth orbit, it will run out of propellant after two hundred seconds of operation and separate from the payload on the top.

The second stage of the rocket, that is, the upper stage rocket, is a Russian-made RD-0172 engine, which plays the role of safety and maneuvering and changing orbits.

In order to reduce the weight as much as possible, the lander does not have such a thing as an escape tower, so the only engine that can provide safety for the command module is this stage, and if the Eagle spacecraft has a problem during launch, then the upper stage rocket can immediately detach from the command module.

If the Eagle spacecraft can be successfully launched, the role of the upper stage rocket is to maneuver and change orbit and assist the command module in rendezort and docking with the United Space Station.

Two-stage rockets, no one can have problems.

If something goes wrong with the first stage of the rocket, then the Eagle spacecraft will crash to the ground.

If the upper stage rocket fails, the Eagle spacecraft will not be able to successfully dock with the United Space Station and become space junk floating in Mars' low-Earth orbit.

Old cats must be cautious.

Fortunately, the liquid rocket engine itself is not a particularly complex structure, in essence, the basic structure of the liquid rocket is a pump plus a combustion chamber and a nozzle, the pump sends the propellant into the combustion chamber, the propellant is ignited and burned in the combustion chamber, and finally sprayed out through the nozzle, simple and crude, and it is a one-time thing, so the old cat can still play.

But if what is in front of it at the moment is an aero engine used in an airplane, such as the F119 turbofan engine, a complex and sophisticated thing, several stages of compressors and several stages of turbines, then the old cat will have to scratch blind.

It is not an engine designer after all.

"Tang Yue!" The old cat shouted.

"What's wrong?" Tang Yue was pushing the small cart towards the lander, and raised his head.

"I'm missing a seven-size inner pentagonal wrench here." The old cat stood on the gangway and looked condescendingly at Tang Yue on the ground not far away, "Help me get it!" ”

Tang Yue was stunned for a moment, and said in his heart, Old cat, you also have this day to ask me for help?

You're finally in my hands.

Tang Yue sneered twice in his heart.

"Take it yourself!" He cleared his throat and said sternly, "Don't you see what I'm busy with?" Where do I have the kung fu to help you get a wrench? ”

"You don't take it?"

"Don't take it!" Tang Yuexin said I can't cure you anymore?

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

"Sure!" Tang Yue said fiercely, "If I help you get the wrench, I will pronounce my name upside down from now on!" ”

"That's fine." The old cat nodded and patted his paws, "If you don't take it, don't take it, I have no opinion, but without this wrench, I can't complete my next work, when will you help me get the wrench, when will I continue." ”

Tang Yue was stunned.

"I am not responsible for delaying the launch." The old cat continued, "Now the life of the little girl above your head is in your hands, you can watch it." ”

"You!"

"What are you?"

"You're awesome."

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

"The wrench is in the second cabinet under the table! Note it's number seven! The old cat shouted behind him, "Yue Tang! ”
