In Kunlun Station, Old Cat and Mai Dong are pounding tomato seeds.

"We need a sprout bed to keep the tomato seeds moist during germination, either with soaked cotton cloth or gauze...... Is Tang Yue back? Mai Dong on the screen saw Tang Yue entering the door and said hello, "The battery panels have been moved?" What's the weather like today on Kunlun Station? ”

"The panels have been moved, it's a sunny day." Tang Yue unloaded the life support system of the Mingguang Armor and threw it there to recharge, "There is a benefit in this ghost place, don't worry about rain when drying pickles, if I am a dried radish, I will definitely like Mars." ”

The old cat found an iron dinner plate, put ten tomato seeds in it, and then opened a package of medical gauze and soaked it with water.

Tang Yue got out of the bloated Mingguang armor, found a corner that the girl couldn't see, took off the clothes on his body cleanly, put on a thermal blanket, and once again turned into a cave man on the top of Mars.

The old cat carefully wraps the tomato seeds in moist yarn cotton and places them on a dinner plate.

"When the seeds germinate, remember that the temperature must be kept at about 25 degrees Celsius, and the low temperature is not good for the germination of seedlings." "After germination, you only need to wait for three to five days for the seeds to germinate, and you can plant the seedlings in the soil after the seeds are white." ”

"What do you mean by Lubai?"

"Lubai is the bud that has emerged, and you can see the white germ." Mai Dong explained.

The old cat nodded, put the wrapped tomato seeds on the shelf, the room temperature of Kunlun Station is twenty-five degrees, this temperature is very suitable for tomato growth, the old cat rubbed his paws, very excited, it will soon be able to see these cute little lives emerging.

Mai Dong breathed a sigh of relief, and the preliminary process of planting tomatoes came to an end here, and then Lao Mao and Tang Yue had to continue to make fresh water and fertilizer while waiting for the seeds to germinate.

"By the way, old cat, I just remembered something." Tang Yue hung the Mingguang armor on the wall, "When I was checking Kunlun Station outside, I found a crack...... It's about that long, on the outer wall to the left of the airlock chamber. ”

Tang Yue gestured with both hands to show the old cat, about thirty centimeters in length.

"Paint off again? When was it discovered? The old cat turned his head.

"Yesterday afternoon."

"Crack?" Mai Dong was a little nervous, "There won't be any problems, right?" ”

"Don't worry, it's a common thing, it's no big deal." Tang Yue shook his head, "It's just that the outer layer of paint is cracked, there is no problem with the main structure, Kunlun Station is also an old house for some years after all, and it is normal to drop paint." ”

Kunlun station is indeed a scientific research station for quite a few years, it has been standing on the surface of Mars for almost ten years, it is the same as the United Space Station, are the product of the early landing missions of the Mars program, since then every Mars landing mission astronauts will maintain the Kunlun station, replace the internal equipment, do some upgrade work and tinkering, the outer wall of the Kunlun station is coated with a layer of white polyester coating to protect the internal structure, this layer of paint will be constantly worn, so regular maintenance is required.

"Do we have any extra paint?" The old cat asked.

"It's gone." Tang Yue spread his hands.

"Is there still clear glue? Patch it up with duct tape. The old cat sighed, "Three years of sewing and three years of sewing, and another three years of sewing and mending." ”

"There's not a lot of tape...... There are a few volumes left, damn it, are those guys eating duct tape? Or did Lao Zheng play with some bundle PLAY? ”

"Who can he play with?" The old cat asked.

"Lao Wang." Tang Yue replied.

"Oh......" the old cat imagined the scene, "Tie Lao Wang's strong gluteus maximus with tape, the picture is so beautiful." ”

Tang Yue pulled open the cabinet and took out the tape, raised his head, saw the girl's depressed expression on the screen, and smiled, "Mai Dong, you don't have to worry about Kunlun Station, this dilapidated house is very sturdy and has a long lifespan, it can boil the old cat to death, and it won't be bad in our lifetime." ”

Tang Yue is telling the truth, among so many things in Kunlun Station, the longest life is Kunlun Station itself, oxygen circulation, fresh water circulation and temperature control system are very delicate and delicate equipment, the use time limit is only more than ten years at most, but the life span of Kunlun Station is to run for hundreds of years, Tang Yue will not see the day when Kunlun Station is damaged and collapsed in his lifetime.

Mai Dong nodded.

Tang Yue put on the Mingguang armor again, carried a large roll of tape, and opened the hatch of the airlock room.

He was going to repair the cracks in the outer wall of Kunlun Station.

“Good Luck！” The old cat waved his paw.

Tang Yue suddenly stood still.

"What's wrong with you?" The old cat turned his head.

"." Tang Yue scolded, "My leg cramps again." ”

Mai Dong tapped lightly on the keyboard, she was managing the various modules in the United Space Station, and during this time Mai Dong tried to learn how to manage the behemoth she was in, adjusting the power of the solar panels and batteries to maximize the life of the space station.

The Mars Joint Space Station is by far the most expensive and complex research facility ever built, and it has many unique advantages that laboratories and ISS on Earth do not have.

The original success of the Mars Joint Space Station was borrowed from the name of the Deep Space Laboratory, promising to provide a good and long-term experimental site, and attracting a large number of strong support from basic disciplines and scientific research institutes - at first, the congressional lords did not agree to spend such a large amount of money to build a space station in Martian orbit, because the Orion spacecraft itself can be used as a transit for landing.

Far from all human interference and noise, the Joint Space Station is an excellent place for electromagnetic and radiation observations, like a quiet chamber in deep space, where any subtle sound in the universe is amplified hundreds or thousands of times.

The space station is large enough to carry large observation equipment, so projects in cosmology and theoretical physics are rushing to squeeze in, and there is a very sensitive neutrino trap in the Dawn module, which is not large, but it kills the results of the Super Kamiokande probe.

There is also an X-ray telescope, which was originally designed to verify Hawking radiation, and by the way, the Hubble constant is reduced to a few decimal places.

There are also large spectroscopic and remote sensing devices that follow the Joint Space Station around Mars and accurately determine the distribution of water and methane on Mars.

And Lao Mai, he brought a lot of scratch paper, and if it hadn't been for Lao Wang's Elder Scrolls and accidents, maybe Goldbach's conjecture would have been solved.

It's just fruitful.

The academic community happily said that the results of the Nobel Prize in physics in the next 20 years will come from the Joint Space Station.

The next mission to Mars is said to be equipped with gravitational wave observation equipment, which is a thin metal pole two kilometers long - to be honest, Mai Dong doesn't know how they are going to send that thing into the sky, but how bold a person is, how big a rocket is.

Mai Dong turned off most of the probes, but she still retained some of the observation equipment to turn in the direction of the Earth, while maintaining the search and tracking of the Orion 1 spacecraft, Mai Dong has not given up the search for the Earth and the Orion spacecraft, she still has a faint hope in her heart - one day when she wakes up, a greeting from the Earth or the Orion 1 spacecraft will pop up on the computer screen.

The space station was still tirelessly collecting radio waves from all directions, and the girl was silently staring at the screen, all she could see was a blank space.

Mai Dong shook his head, this kind of waiting is pointless.

She turned to leave the crystal pod.

Mai Dong passed through the interface of the cabin, and suddenly there was a faint sound of "drop-" behind her, and the girl was stunned, turned her head, and did not move.

Did you hear it wrong?

A few seconds later, there was another "drip-" sound in the core cabin, this time she heard it clearly, Mai Dong's brain was almost blank, and a sudden ecstasy surged into her heart, this was the signal! The space station has received an unfamiliar radio signal!
