The Xiaguang, which sailed in the deep space, slowly approached the silver-white "port."

Then, a pair of long-shaped "landing gear" slowly extended from underneath the head of the Xiaguang, pointing to the section with the interface at the lower end of the space station, and then slowly approaching the past.

Sitting in the cabin, looking at the space station gradually approaching the porthole, Johnson's heart almost mentioned the eyes of the blind, the nervous palms oozing sweat.

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

This not only tests the "hardware strength" of a country's industrial camera precision, 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. The window period of the engine ignition is often compressed to within one second. One second and one second later will cause the docking failure. .

At the beginning, when the US Gemini manned space program just came out, it took nearly a year for Gemini to reach the 6th and 7th. However, after maintaining a distance of 30 cm for 20 minutes, the two spacecraft eventually did not achieve docking. It was only in the following year that Gemini No. 8 was successfully docked with the unmanned target spacecraft, and the United States was truly mastered in this technology.

The docking of the manned spacecraft was until the mid-1970s, when the United States and the Soviet Union "shake hands and talk" in the aerospace field, and finally realized under the joint efforts of the two superpowers.

The reason why the Apollo program did not choose to launch the moon landing components in a row, after going to the moon after the high-orbit "convergence", one of the main reasons is that the docking is too difficult. In contrast, large thrust rockets are more acceptable in terms of both risk and cost.

Compared to Tavi and Jones, Johnson has served much longer in the Nasa Astronauts' brigade, and he knows how difficult it is.

However, just when he had not reacted, the pair of "landing gear" of the Xiaguang was inserted in the lower side of the multi-functional docking bay of the Yuegong.

With a slight to almost imperceptible jitter, the Xiaguang, which successfully connected the "landing gear" to the space station, slowly pulled itself toward the space station as the "landing gear" contracted.

In the end, the docks of the large and small spacecrafts were tightly integrated.

then……

There's no after that.

The docking process of the entire spacecraft did not give a feeling of tension, and even the simplicity was unacceptable.

"...wtf?"

Looking at everything outside the porthole, Johnson seemed to have never seen the world, and was completely there.

He has been trained in the NASA astronauts' brigade in this area. It is clear that the docking of the spacecraft is not the case!

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

It is unheard of for him to directly release the landing gear like Xiaguang and take the initiative to meet the space station.

At this time, the signal light of the hatch lights up.

As the door of the room was unlocked, Taiwei, who supported the door frame and floated out of his room, moved his lower limbs, and then he saw Johnson, who was staying there, and asked without doubt.

"Man, what's wrong with you?"

Johnson looked at him with a strange look.

"... Didn't you see it? The Chinese people docked the spacecraft."

Facing the captain's strange sight, Tavi grabbed his head and shook his head.

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

Johnson sighed,

"...when I didn't ask."

Asking a complicated question about an idiot, he must be crazy.

According to the indicator light, three colonists returning from Mars went to the cabin to gather. Immediately after the alloy door in the middle of the cabin slowly opened, Liu Wei, wearing a spacesuit in the cabin, floated in.

"Xiaguang has successfully docked at the lunar space station of the Moon Palace. We will check your physical condition after half an hour and disinfect the space inside the spacecraft..."

At this time, Liu Wei suddenly noticed that the white male astronaut had a ghost-like expression on his face, so he smiled and looked at him and said, "Are you alright?"

"I... very good," John returned, and Johnson's throat moved slightly. He finally couldn't help but ask, "How did you do it?"

Liu Wei looked at him with a fog: "What did you do?"

Johnson opened his mouth and didn't know where to ask and didn't know how to speak.

Do you ask directly "How do you dock the spacecraft?"

Perhaps for them, it is only a matter of course to directly access the access station, just as he understands the spacecraft docking technology.

It’s just that he still can’t accept the reality that the aerospace technology in China has progressed to a casual detail, which will make him feel shocked.

Looking at this smiling, friendly Chinese astronaut, Johnson smiled stiffly twice.

"Nothing... when I didn't ask."

Although it is the same sentence, at this moment his heart is completely different mood...

After the Xiaguang and the Moon Palace's multi-functional docking station were connected, the three Martian colonists, under the leadership of Liu Wei, passed through the joint and entered the air lock chamber of the multi-functional docking cabin.

When there is no spacecraft docking, here is the buffer zone for the stationed astronauts to enter and exit the space station. Astronauts who work outside the cabin will change their space suits, check equipment, and adapt to air pressure...

But now because there is a spaceship connected, the airlock is used as a zero-hour checkpoint.

"...you are waiting here. There will be doctors from professional doctors to check your body for a while. When you have confirmed your health, I will consider taking you to the moon palace."

Looking at Liu Wei, standing at the door of the cabin, Johnson, who had just taken off the cabin spacesuit, asked: "What do we need to do now?"

Liu Wei smiled and said: "Eat something, drink something, and then... the medical team from the United Nations may need you to provide a little feces and urine."

Jones asked a red face: "Here?"

"Of course it can't be here," Liu said with a light cough, pointing to the alloy door next to the wall. "There is a separate toilet next to it."

Did not let these colonists wait too long.

With the help of two months of station staff, Johnson and others quickly completed the physical examination. At the same time, metabolite samples collected from three people were also sent to a dedicated experimental chamber.

The samples responsible for testing these samples were Professor Leslie from the Institute of Microbiology at the Lehman Health Medical Center in Switzerland, and Dr. Zhao Shuxuan from the Institute of Biomedical Research at the Chinese Academy of Sciences.

Both scholars are big cattle in the biological field, and have published many articles in the field of astronomical astrobiology. Although it is not the most authoritative big cow, it is also a top scholar.

And the most important thing is that both of them are under the age of forty-five, relatively young and physically good. Although many authoritative Daniels also want to grasp this opportunity, but the age is really too big, can only look at Star Technology's weightless simulation device to blink.

Time passes by one minute.

Whether in the experimental cabin or in the experimental cabin, everyone is nervously waiting for the results of the test.

At this time, Professor Leslie, who was sitting in front of the electron microscope, suddenly whispered a whisper, and there was a hint of surprise and ecstasy in his eyes.

"Oh, Shet..."

"What did you find?" Stepped to the side of the electron microscope, Zhao Shuxuan pushed the glasses on the bridge of the nose, approached the computer screen, frowned, "...is this?"

"A very strange anaerobic bacterium with thick cell walls and cell membranes...etc. Let me correct it, it is spore! No wonder it can survive on Mars," constantly adjusts the magnification of the electron microscope, staring Professor Leslie’s expression on the screen gradually became excited. “God...unbelievable.”

Staring at the image on the screen, Zhao Shuxuan’s eyes flashed a bit of excitement, but soon he gradually became dignified.

"We may be in trouble."

Leslie smiled and looked back at Zhao Shuxuan, pushing the glasses on the bridge of the nose.

"In theory, it's true, but it's exciting? Isn't it?"

Sitting in the cabin quietly waiting, but after a long time there was no movement.

Just as Johnson and others began to be restless, the door suddenly opened. Not only the Chinese who had brought them here before, but also followed him with a man who looked a little majestic.

Johnson vaguely remembered that he seemed to have seen this side when he was on the Xiaguang. If he did not guess wrong, he would probably be the captain of Xiaguang.

Before I had time to ask what was going on, Taiwei, who was sitting next to him, took the first step and hurriedly stood up and asked.

"What happened? What is the medical examination that takes so long? When can we go home?"

"Sorry, guys."

Raising the volume interrupted the black brother's general problem, and Xu Zhenghong's face was a little dignified, and said with a heavy voice.

"I am afraid that I will be postponed when I go home."
