Mai Dong took several deep breaths repeatedly, inhaled the air in the mask into her lungs, and then exhaled it for a long time, and she turned down the temperature in the cabin suit, which could keep her feverish mind clear.

"Miss Mai Dong, the temperature inside your cabin suit is decreasing." The old cat monitored Mai Dong's condition, "At the same time, your heart rate is rising. ”

"yes, I know." Mai Dong replied, "Because the temperature in the spacesuit is too high, it's a little hot, and I'm sweating all over...... I must take a bath when I go back, I haven't taken a bath in a long time, and my body is about to ferment. ”

"The water circulation system on the space station is still normal, right?" Tang Yue asked.

"Normal." "The water and air circulation are in good condition, and unlike your ground station, the space station is completely confined and there is basically no water dispersion...... I really miss the feeling of showering on the ground, it's so cool, but the bath water doesn't run down at all on the station, all that comes out is mist and sticks to my skin. ”

The girl snorted, apparently very unhappy with the bathroom inside the United Space Station.

"I've forgotten what it's like to take a shower." Tang Yue said dryly.

"The folding bathroom in Kunlun Station may not have been opened for half a year." The old cat said lightly, "When I checked it yesterday, I found a layer of dust on it. ”

"I haven't taken a bath for half a year......," the girl said, "won't it get moldy?" It's also uncomfortable to wear. ”

"Have you forgotten?" The old cat said, "This thing doesn't usually wear clothes. ”

"Wow...... Boys are terrible. Mai Dong stared at the screwdriver in her hand, she was disassembling the screws on the shell, "I can't imagine what kind of life it is, is Kunlun Station like a garbage heap now?" It is said that cockroaches will grow in dirty clothes...... I had to take a shower every once in a while, so I cut my hair short to save water. ”

"Hi Hi girl, it's a man's natural talent to stay clean without taking a bath, even if we don't take a bath for a long time, we're still spotless." Tang Yue said, "Lin Qingxuan once said that spotlessness is not that there is no dust, but that the dust makes it fly, and I am my own sunshine." ”

"Yo." The old cat glanced at him, "You're quite philosophical. ”

"I am a critical philosopher of the new generation of bachelors like Kant." Tang Yue said.

"You're just a ball...... the old cat sneered.

"You're a ball!"

"What balls? Vulgar. The old cat looked dazed, "I said you were just a faint sad person." ”

Damn it.

Tang Yue scolded in his heart, this ghost cat is learning more and more well.

Holding an electric screwdriver, Mai Dong sucked out the third screw and carefully packed it into the bag.

Due to weightlessness, everything will float around, so the pocket must have a lid, and the larger tools cannot be stuffed into the bag, so they are inserted into the protective case to be fixed.

"Mr. Cat, Tang Yue, the shell of the sensor can be opened...... There is one last screw left. Mai Dong also removed the last screw, and then put the electric screwdriver into the tool bag, "All four screws have been removed, and now the lid can be opened." ”

The girl's movements were very slow, and the old cat and Tang Yue were watching the surveillance video of the camera in Kunlun Station, as if they were watching slow motion.

The extravehicular suit used for spacewalking is even more bulky and bulky than the Mingguang armor, but with the super boom transport, it saves a lot of effort, otherwise it would be too laborious to use a spacebike or climb over it step by step.

Mai Dong opened the sensor's housing, revealing the wiring inside.

"Mr. Cat, I need to move a little further to the left."

The old cat manipulated the mechanical arm to move slowly, Mai Dong adjusted her posture, approached the opening on the sensor shell, in order to avoid observation blind spots, she also tied a small mirror in the palm of her right hand, which is also a skill taught to her by Tang Yue, with a mirror can go deep into the corners that many eyes can't penetrate.

"Mai Dong, adjust the lens of the camera, we need to assess the damage to the line."

Mai Dong nodded, pointed the camera at the maintenance opening, as the field of vision moved, the old cat and Tang Yue could also see the control lines inside the sensor, the complex cables of various colors were densely arranged together, each line had a white number, they extended from different positions, and went to different places, Mai Dong was not a professional electrician, she couldn't read the letters and codes on these wires.

Tang Yue sat in front of the computer monitor, holding the action plan in his hand, and instructed Mai Dong to use a long tweezer to pull through the surface cable and find the C1002 line.

"How's it going?" The old cat asked.

"A disconnect between the data processor and the actuator." Tang Yue pondered for a few seconds, "The best repair plan is to replace it, replace this line, Mai Dong, you see...... This crimson wire is connected to the sensor data processor, and the next is connected to the actuator control unit, do you see that wire? ”

"See."

"What you want to replace is this wire, I suspect that the cause of the failure is that the core is broken, the end of this line is fixed with a hexagonal nut, you need to unscrew this nut when replacing the wire, the other end is the same, the operation is very fine, it will be a little difficult." Tang Yue asked, "Can it be done?" ”

"No problem." Mai Dong nodded.

"Twenty minutes until the sun goes down, continue the operation or return to the space station?" The old cat glanced at the time.

"I can continue." Mai Dong blinked, beads of sweat stuck to her eyelashes, she subconsciously wanted to raise her hand to wipe the sweat, and then she realized that she was wearing an extravehicular suit.

"That's it." Tang Yue shook his head, "The stage goal of the first exit from the cabin has been completed, you need to rest now, disassemble the wires and come back when you go out of the cabin for the second time, we have time, don't rush at this time, the sun is about to set on your side, it is very inconvenient to operate in the dark, and it is easy to have problems...... Old cat, pull Mai Dong back. ”

Mai Dong let out a sigh of relief, put away all the tools, and then leaned back in the extravehicular suit to rest, waiting for the super arm to start.

She looked up, and the girl was close enough to see the towering solar panels, the height of a thirteen-story building, second only to the main truss in the space station.

Mai Dong didn't feel their enormity when she stayed in the core cabin, but when she really got closer, she realized the grandeur of these giants, there were eight solar sail panels in total, and when the eight forty-meter-high sail boards were neatly lined up in front of you, you would be amazed from the bottom of your heart.

When you realize that this is the orbit of Mars, 100 million kilometers away from Earth, the amazement turns into shock.

The super boom activated, and slowly moved away from the battery pack with Mai Dong.

Sunlight shines through the gaps in the solar panels, and the rugged trusses, rectangular solar cells, and cylindrical cabins form a complex composition in Mai Dong's eyes:

Against a dark and indifferent empty background, the cutting-edge creations of human heavy industry occupy most of the painting, with a clear demarcation between light and shadow, pure machinery, pure coldness, pure physics and engineering, like a monster born directly from the rules of the universe.

The sun is a bright source of light, it seems distant and warm, slowly passing between the void and the machine, casting a faint golden glow over the painting.
