From the perspective of the earthlings, Kunlun Station is undoubtedly a desert shack with a simple structure, and the entire Kunlun Station is composed of two parts.

The core of the main station is a low round tortoise shell, an aluminum alloy truss structure, the shell is a high-strength engineering plastic, deeply rooted in the soil on the surface of Mars, about 15 meters in diameter, from the appearance of a white yurt flattened.

The core cabin is Tang Yue's main activity venue, which is the hall, kitchen, warehouse, gym, conference room, laboratory, and main control room of Kunlun Station - it has most of the functions of Kunlun Station.

Seven small chambers are radially attached to the outer part of the core module, six of which are members and one is an airlock.

The area of the member cabin is pitifully small, and it is not a rigid structure, in the words of the captain Lao Wang, that is, even if you fart, you are worried about breaking through the wall...... The six compartments are inflatable, modular and replaceable, and they were all flattened and packed in boxes when they were first shipped.

The second part of Kunlun Station is the garage, which is simpler than the structure of the main station...... It's a shipping container, and the rover usually stops in the container.

Tang Yue first checked the charging status of the battery.

The batteries were already fully charged, and this power mainly provided energy for the life support system at night, and the solar panels were useless when the sun went down, so Tang Yue had to put them away.

"Are you going to collect the panels?" The old cat asked.

Tang Yue took off the extravehicular suit hanging on the wall, "Yes, it's going to be dark soon, and you have to put the battery board away." ”

"Stay safe." The old cat nodded.

Tang Yue unzipped the back of the extravehicular suit, and then bent down to get in, the extravehicular spacesuit is a very heavy thing, weighing sixty kilograms, but fortunately, the gravitational pull of Mars is only forty percent of that of the earth, that is to say, sixty kilograms of things are worn on the body, which is only equivalent to twenty-four kilograms on the earth.

The old cat came over to help Tang Yue zip up, and then buckled the huge life support system.

The life support system is a thing shaped like a trolley box, this box integrates all the functions that can keep Tang Yue alive, as long as he leaves Kunlun Station, Tang Yue has to carry this turtle shell wherever he goes.

The green indicator light on the inside of the mask is on, indicating that the life support system is switched on and the spacesuit is in normal condition.

"The Mingguang armor is in normal condition, and the air tightness is intact." Tang Yue talked to the old cat through the headset and gave a thumbs up.

The old cat patted Tang Yue's mask and gave a thumbs up on his paws.

Mingguang armor is the nickname of the scientific expedition team's extravehicular activity clothes, because this suit is really too bulky and bulky, it is a semi-rigid structure, the entire upper body of the extravehicular suit is a hard shell, the helmet and shoulders are fixed together, and the limbs and joints are connected by alloy bearings and steel rings, so it looks like ancient armor.

Wearing Mingguang armor to go out of the cabin, there is a feeling of going out to fight the Martians.

Tang Yue didn't like this outfit, he couldn't even bend down in Mingguang armor.

“Good Luck！” The old cat's voice came out of the earphones, Tang Yue raised his head, saw the old cat standing in the hall and waved his hand.

Tang Yue nodded, turned around and laboriously opened the hatch of the airlock chamber.

Once he put on the extravehicular suit, Tang Yue seemed to be isolated from the world, on the one hand, because the sound insulation effect of the helmet was so good, Tang Yue put his head into the mask, and the surrounding noise immediately disappeared. On the other hand, because the extravehicular suit was too thick, Tang Yue felt that he had not put on a set of clothes, but had entered a house.

The airlock chamber is a cylindrical cabin that is horizontally placed, connected to the core module at one end and the exit from Kunlun Station at the other.

The airlock chamber was six meters long, nearly three meters in diameter, and there was a safe-like hatch at each end, Tang Yue bent down into the airlock chamber, turned around and closed the hatch behind him, and confirmed that the hatch was locked.

Through the glass viewing window on the hatch, he could clearly see the old cat inside.

Tang Yue walked through the airlock room step by step, and then opened the exit of Kunlun Station, the airlock room was connected with the Martian atmosphere outside the moment the door was opened, the red warning light overhead lit up, and the air pressure dropped rapidly.

The atmospheric pressure of Mars is less than one percent of that of Earth, and if he is not directly exposed in an extravehicular suit, then Tang Yue will not survive for a minute.

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

"I'm out of the cabin and feeling good."

Tang Yue took a deep breath, the majestic and magnificent desert of Mars spread out in front of his eyes, the sun was already setting in the west, and the sky was getting dark.

Not far away is the rover's garage, and a little further away is the tall Eagle spacecraft, its white lander standing on the sand, its smooth and soft curves at odds with the rough and wild desert around it.

In the open space in front of Kunlun Station is an array of solar panels.

The intensity of sunlight on Mars is less than half that of Earth, which means that more and larger solar panels must be used on Mars to meet the needs of the Kunlun station.

The main source of power for the Kunlun station is the solar panel array, which has more than 40 panels with a total power of 9 kilowatts, and needs to occupy an area the size of half a standard 400-meter playground when fully deployed.

Every morning, Tang Yue had to manually unfold them piece by piece, and at night, before the sun set, Tang Yue had to take them all back indoors.

Once the sun sets, the surface temperature of Mars drops to minus 80 degrees Celsius, and sometimes even minus 100 degrees Celsius, which can greatly deplete the life of the panels.

There is no spare solar panels, and if they are broken, they will be missing, so Tang Yue must take good care of them.

Tang Yue carried a brush in his hand and began to clean the sand and dust on the battery board, and after cleaning it up, he moved it back to the garage.

Due to the thin atmosphere, the wind on Mars is usually not as strong as on Earth, but it will still raise dust, and these fine dust will fall on the surface of the panel, which may invade the gaps of the circuit board, block the heat dissipation opening, and cause short circuits or open circuits, so Tang Yue has to clean up every day.

"Tang Yue." The old cat's voice came out of the headphones.

"Huh? I'm listening. ”

Tang Yue knelt on the ground, because the extravehicular suit was semi-rigid, and the upper body could not be bent, so bending was a problem, and all the tools in Kunlun Station were long-handled, which was to let the astronauts avoid bending over as much as possible.

Tang Yue pushed the filter mask up, held a long-handled brush, and carefully cleaned the battery board.

"How many supplies are you going to send to Miss Mai Dong?" The old cat asked, "I'm going to make a plan." ”

Tang Yue stopped what he was doing and thought about it.

"Give half of it."
