Sailing in deep space, the Xiaguang slowly approached the silver-white "port".

Immediately afterward, a pair of long strips of "landing gear" slowly stretched from under the nose of the Glow, pointed to the module with the interface at the end of the space station, and then slowly approached.

Sitting in the cabin, watching the approaching space station outside the porthole, Johnson's heart almost rose to his throat, and sweat oozed from his nervous palms.

The docking of space vehicles has always been a difficult point in space technology.

This not only tests the "hardware strength" of a country's industrial camera accuracy, spacecraft material strength, engine and its control technology, but also tests a series of software strengths such as computer vision measurement technology.

In particular, the requirements for the orbital altitude and speed accuracy of the spacecraft are even more demanding to an outrageous degree, and often the window period of engine ignition will be compressed to less than one second, and one second earlier and one second later will lead to docking failure.

At the beginning, when the Gemini manned space program of the United States first came out, it took nearly a year for Gemini 6 and 7 to achieve rendezvous. However, after 20 minutes of flight at a distance of 30 centimeters, the two spacecraft did not dock. It was not until Gemini 8 the following year that it successfully docked with an unmanned target spacecraft, and the United States could be regarded as mastering this technology in the true sense.

As for the docking of manned spacecraft, it was not until the mid-70s that the United States and the Soviet Union "shook hands and made peace" in the field of space, and it was finally realized with the concerted efforts of the two superpowers.

One of the main reasons why the Apollo program did not choose to launch the lunar landing components in batches and went to the moon after the "rendezvous" in high orbit was that the docking was too difficult. In contrast, high-thrust rockets are more acceptable in terms of risk and cost.

Johnson has served in NASA's astronaut corps for much longer than Tywi and Jones, and he knows how difficult it can be.

However, before he could react, the pair of "landing gear" of the Xiaguang had been inserted into the underside of the multi-functional docking module of the Yuegong.

With a slight tremor that was barely felt, the Xiaguang, which had successfully connected the "landing gear" to the space station, slowly pulled itself towards the space station as the "landing gear" contracted.

In the end, the docking devices of the two spacecraft, one large and one small, were closely combined.

And then......

There is no then.

The entire docking process of the spacecraft did not give people a sense of tension at all, and it was even so simple that it was a little difficult to accept.

“…… WTF？ ”

Staring blankly at everything outside the porthole, Johnson was completely stuck there as if he had never seen the world.

Having been trained in this area in NASA's astronaut corps, he knows very well that the docking of spacecraft is not like this at all!

The correct posture for docking a spacecraft in outer space should be to fly the spacecraft in front of the space station, then turn around and slow down, and wait for the space station to "catch up".

The operation of directly releasing the landing gear and taking the initiative to fly up to the space station like the Xiaguang is simply unheard of for him!

Just then, the signal light of the hatch came on.

As the door of the room was unlocked, Tai Wei, who floated out of his room by holding on to the door frame, moved his lower limbs, and then saw Johnson who was stunned there, and couldn't help but ask in confusion.

"Dude, what's wrong with you?"

Johnson looked at him strangely and spoke.

“…… Didn't you see that just now? The operation of those Chinese docking spacecraft. ”

Facing the captain's strange gaze, Tai Wei scratched his head with a sad face and shook his head.

"I don't quite understand what you're talking about."

Johnson sighed,

“…… When I didn't ask. ”

Ask a fool such a complicated question, he must be crazy.

According to the indicator light, the three colonists who had returned from Mars walked to the cabin to assemble. Immediately after that, the alloy door in the middle of the cabin slowly opened, and Liu Biao, who was wearing a spacesuit in the cabin, floated in.

"Xiaguang has successfully docked at the Moon Palace lunar space station, we will check your physical condition in half an hour, and at the same time disinfect the space inside the spacecraft......"

At this time, Liu Biao suddenly noticed that the white male astronaut had a ghost-like expression on his face, so he looked at him with a smile and greeted, "Are you okay?" ”

"I ...... Very good," Johnson came back to his senses, and Johnson's Adam's apple moved slightly, and finally he couldn't help but ask, "How did you do it?" ”

Liu Biao looked at him confused: "What and how?" ”

Johnson opened his mouth, not knowing where to start or how to speak.

Do you just ask "how did you do the docking of spacecraft"?

Perhaps for them, it is just a matter of course to go directly to the access station, just like his understanding of spacecraft docking technology.

It's just that he still can't accept such a reality, Huaguo's aerospace technology has advanced to the point that any detail will make him feel jaw-dropping.

Looking at the friendly Chinese astronaut, Johnson stiffened his expression and chuckled dryly.

"Nothing...... When I didn't ask. ”

Although it was the same sentence, he was in a completely different mood at this moment......

After the connection between Xiaguang and the multi-functional docking module of the Moon Palace, the three Martian colonists, led by Liu Biao, passed through the connection port and entered the airlock chamber of the multi-functional docking module.

When there is no docking spacecraft, it serves as a buffer zone for on-site astronauts to enter and exit the space station. Astronauts who go to work outside the capsule will change their spacesuits, inspect their equipment, and adjust to the air pressure......

However, now that the spacecraft is connected, the airlock chamber is used as a zero-hour checkpoint.

“…… You wait here, there will be a professional doctor to check your body in a while, and when your health is confirmed, I will consider taking you into the Moon Palace for a spin. ”

Looking at Liu Biao standing at the door of the cabin, Johnson, who had just taken off the spacesuit in the cabin, asked, "Then what do you need us to do now?" ”

Liu Biao smiled and said, "Eat something, drink something, and then ...... The medical team from the United Nations may need a little bit of feces from you. Poop and urine. Liquid. ”

Jones blushed and asked, "Here?" ”

"Of course it can't be here," Liu Biao coughed lightly and pointed to the alloy door embedded in the wall next to him, "There is a separate toilet next to it." ”

It didn't keep the colonists waiting long.

With the help of two staff members stationed on the Moon Palace, Johnson and the others quickly completed their physical examinations. At the same time, the metabolite samples collected from the three people were also sent to a special experimental cabin.

The samples were tested by Professor Leslie from the Institute of Microbiology at the Lehmana Health Center in Switzerland, and researcher Shuxuan Zhao from the Institute of Biomedical Sciences of the Chinese Academy of Sciences.

Both scholars are well-known in the field of biology and have published many articles in the field of astrobiology, which is an unpopular branch. Although he is not the most authoritative bull, he is also a top first-line scholar.

And the most important thing is that both of them are under the age of forty-five, which is relatively young, and their physical fitness is also good. Although many authoritative bulls also want to seize this opportunity, they are too old, so they can only stare at the weightlessness simulation device of Star Technology.

Minutes and seconds passed.

Whether outside the experimental chamber or inside the experimental chamber, everyone was nervously waiting for the results of the assays.

At this moment, Professor Leslie, who was sitting in front of the electron microscope, suddenly whispered a word, and a trace of surprise and ecstasy was written in his eyes.

"Oh, Shet......"

"What did you find?" Walking quickly to the side of the electron microscope, Zhao Shuxuan pushed down the glasses on the bridge of his nose, approached the computer screen, and frowned, "...... This is? ”

"A very strange anaerobic bacterium with a thick cell wall and membrane...... Wait, let me correct it, it's a spor! No wonder it can survive on Mars," Professor Leslie's expression grew excited, constantly adjusting the magnification of the electron microscope, staring at the screen, "God...... Unbelievable. ”

Staring at the image on the screen, Zhao Shuxuan's eyes also flashed with a hint of excitement, but soon became solemn.

"We might be in trouble."

Leslie glanced back at Zhao Shuxuan with a smile and pushed down the glasses on the bridge of her nose.

"That's true in theory, but exciting? Isn't it? ”

Sitting in the isolation chamber and waiting quietly, but no movement came from it for a long time.

Just when Johnson and the others began to fidget, the hatch suddenly opened. It wasn't just the Chinese man who had brought them here who had walked in, but beside him was a man who looked a little more dignified.

Johnson vaguely remembers that he seemed to have seen this when he was on the Glow, and if he was not mistaken, he was probably the captain of the Glow.

Before he could ask what was going on, Tai Wei, who was sitting next to him, took the lead and hurriedly stood up and asked.

"What happened? What is it that takes so long for a medical check-up? When are we going to go home—"

"Sorry, guys."

Raising the volume interrupted the black brother's barrage of questions, Xu Zhenghong's face was a little solemn, and he said in a heavy voice.

"I'm afraid we'll have to postpone our home."
