Great Country Academician

In the space capsule, after hearing the words of the captain Zhai Zhigang, Liu Yang came over and took a look at the data on the thermometer.

37.3℃.

This is a very subtle number. Under normal circumstances, the body temperature of an adult fluctuates between 36-37℃, and it is considered a fever if it exceeds 37.3℃.

And 37.3 degrees Celsius is just stuck in the middle.

Of course, this refers to normal circumstances.

If it is after exercise, a body temperature exceeding 37.3 or even 38 degrees Celsius is normal.

However, for the four-person team carrying out the manned Mars landing mission, there are not many tasks in the return phase, and the whole process is relatively easy.

So in theory, her body temperature should not exceed this number.

Looking at the temperature data on the thermometer, Liu Yang hesitated and said, "Captain, do you want to measure it again? I don't feel anything abnormal in my body."

Although in a state of weightlessness, a person's body temperature will be higher than that of a normal person.

This phenomenon of rising body temperature is due to the fact that in a state of weightlessness, the astronauts' bodies find it difficult to consume excess heat, causing the core body temperature to gradually rise.

And the rate at which sweat evaporates in space is slower than on Earth, which explains why astronauts' body temperature rises particularly quickly when they are active in the International Space Station.

But on the Hanhai Space Shuttle, they are equipped with the most advanced life support system. Except for the problem of weightlessness, all other conditions are simulated on Earth.

They are even luxurious enough to be equipped with a 24-hour uninterrupted ventilation and air circulation system.

This is a function that the International Space Station does not have.

So under normal circumstances, their body temperature should be kept below 37 degrees when they are resting.

And in the physical examinations in the past week, the recorded data did indeed hover between 36.8 and 37.1 degrees.

Hearing Liu Yang's request, Zhai Zhigang nodded and picked up the thermometer to remeasure her body temperature.

37.3.

The data displayed on the thermometer did not change.

"It's still 37.3 degrees." Zhai Zhigang shook his head and took the infrared temperature gun and pointed it at his forehead.

A number popped up on the temperature display screen.

37.2℃.

Seeing this number, he couldn't help but frowned, called Jiang Xinlin and Tang Haibo to the side, and measured the temperature of the two respectively.

37.2℃.

37.4℃.

Two different temperature numbers came into view, making Zhai Zhigang frown deeply, and the uneasiness in his heart began to emerge from the depths.

If it is said that Liu Yang's body temperature data has slightly increased, it doesn't mean anything.

But the body temperature of the four people who were traveling together has increased slightly compared with the previous data, which is definitely worthy of vigilance.

After a little thought, Zhai Zhigang opened the temperature table that recorded the past week and carefully examined the data.

But the past body temperature test report did not provide him with any clues.

In the last test report four hours ago, Liu Yang's temperature was still 37.0 degrees Celsius, and the temperatures of the three of them were all below 37 degrees Celsius.

Going back, the data on the temperature test report also fluctuated around this level, and there was no particularly prominent or regular change.

"Captain, what's wrong?"

Seeing Zhai Zhigang standing there with a frown on his face, flipping through the temperature report, the youngest Jiang Xinlin came over and asked.

After a long sigh, Zhai Zhigang said with some concern: "This time the temperature test is slightly higher, Liu Yang and I are both 37.3, you are 37.4, Hongbo is 37.2, which is 0.2-0.3 degrees Celsius higher than the record data four hours ago."

Hearing this, Jiang Xinlin said in surprise: "37.4 degrees? But I don't feel any obvious problems with my body?"

For astronauts who have undergone rigorous training, being keenly aware of their own physical health is one of the core foundations.

Because in space, excessive fluctuations in core body temperature can affect physical and cognitive performance, and even endanger life.

Therefore, it is a skill that everyone must master to find out whether there are health problems in their body in time.

After all, there is no trivial matter in space travel, and once an unexpected situation occurs, an elite astronaut may be lost.

Floating on the opposite side, Zhai Zhigang frowned slightly, recording today's temperature test data while saying: "Send the data back to the Earth headquarters first, and then continue to observe the situation and see what happens next."

"Everyone will draw blood and do an electrocardiogram to check the situation first."

"In addition, if there is excrement today, collect some for a simple test to see if there is any problem."

After a slight pause, he continued: "In the next period of time, everyone should keep an eye on their physical health. If any discomfort occurs, report it in time."

"Of course, there is no need to worry too much. The previous physical examination data is normal. It has been more than a week. We should have passed the safe period. Just relax a little. Don't worry about it, which will cause abnormal body temperature or something."

In the space capsule, Liu Yang and the other two nodded. They knew that anxiety would lead to a series of physical health problems.

Especially in this state, you may not have been infected, but you are more anxious and worried, and your body may simulate the symptoms of being infected.

This situation is not uncommon.

Sometimes you are not sick, but you feel that you are sick, and then you go to the hospital and can't find out, and finally your body collapses little by little.

So for astronauts, it is very important to keep their mentality calm and not panic.

At the same time, on the other side.

Jinling, Xiashu Space Base.

"Okay."

"I know."

"I will notify Academician Xu."

In the office, Chang Huaxiang hung up the phone with a serious face and quickly opened the mailbox.

In the special mailbox of the intranet of the space base, an encrypted email was flashing.

This is a signal that only appears in an emergency, which means that they have encountered something that needs to be dealt with immediately.

And the one who sent this email is the working group that maintains contact with the manned landing engineering team.

Quickly download the attachment in the email, enter the password to unlock it, and Chang Huaxiang read the entire email with sharp eyes.

Then, he picked up the red phone on the table and dialed the number of Xinghai Research Institute.

On the other side, in the office, Xu Chuan was reading the information about bionics intelligent prosthesis and brain-computer interface chip sent by Xu Xiao.

The girl was going to bring these two technologies to the market, and asked him to help see what needs to be processed or "optimized".

After all, the value of these two technologies is invaluable, and launching them rashly may cause a series of problems.

Especially the brain-computer interface chip technology, if further research is carried out, it can be expanded into virtual reality technology.

Compared with the interface chips that can only be used for medical treatment at present, virtual reality technology can change the whole world and set off a new information revolution.

Let alone Xu Xiao, even he has to treat it with caution.

At this time, a rapid call rang in the office.

Hearing this sound that was different from the usual call, Xu Chuan was slightly stunned, and then quickly picked up the mobile phone from the table.

Unlike the red phone in TV and movies, there is no so-called red dedicated line in his office.

After all, due to various reasons, his office and research locations are not fixed. Even if he stays at the research institute more often, his daily stay time will not exceed one-third of the total time, or even less.

So the red emergency hotline was directly pressed on his mobile phone.

Therefore, the mobile phone he uses is specific, and there are two types of incoming call ringtones, one is the daily call during normal times, and the other is the short and rapid ringtone now.

This work is organized and uploaded by Liujiu Book Bar~~

The latter means that someone has called him through the emergency phone, and there is something important.

And since he got this phone until now, no one has ever called him through the emergency phone. So he almost didn't react when he suddenly received an emergency call today.

"Hello."

After quickly answering the phone, Xu Chuan asked in a steady voice.

"It's me, Chang Huaxiang."

The voice of Academician Chang Huaxiang came from the other side of the phone: "Xu Chuan, are you busy now? If not, come to the space base now. The four astronauts of the Mars landing team have some abnormal conditions in their bodies, and they may be infected by the microorganisms on Mars."

Hearing this, Xu Chuan's pupils suddenly contracted. The thing he was most worried about still happened.

The microbial life on Mars may cause harm to humans.

"Okay! I'll go there right away."

He agreed directly, and Xu Chuan didn't ask about the specific situation. He hung up the phone in a hurry and got up and rushed downstairs.

"Zheng Hai, come now and take me to Xiashu Space Base."

"Okay, I'll be downstairs right away."

The half-hour journey was not considered long in the past, but today it made Xu Chuan feel anxious.

In the Red Flag car, he had already read the physical examination information of the Mars landing team sent by Academician Chang Huaxiang, but as a non-professional, he had no way to understand what happened from it.

But he could see the report that the body temperature of the four members of the Mars landing team rose and suspected Martian microorganisms were detected in their excrement.

After rushing to the Xiashu Space Base, Xu Chuan pushed open the car door and ran towards the office of Academician Chang Huaxiang.

Without bothering to knock on the door, he pushed the door open and walked in.

"What's the situation? Mr. Chang."

Looking up at Xu Chuan who rushed over, Academician Chang Huaxiang took off his glasses on the bridge of his nose and spoke with a trace of worry.

". It's not completely certain for the time being."

"Although the body temperature of the four members of the Mars landing team has risen slightly, and traces of suspected Martian microorganisms have been detected in their excrement."

"But according to the feedback from the four astronauts themselves, there is nothing abnormal about their physical and mental state at present, and there are no symptoms of infection with the virus."

"In addition, no abnormalities were found in the vital signs such as heart rate, blood pressure, blood oxygen saturation, and blood sampling."

"Including weight, although it has been decreasing due to the weightlessness in space, the decrease is within the allowable standard range."

After quickly explaining the current situation, Academician Chang Huaxiang continued, "I have notified the medical staff. Professor Zhao Ming and Professor Chen Yunze should be here soon."

As soon as he finished speaking, the door of the office was knocked twice, and then two middle-aged men pushed the door open and walked in quickly.

"Academician Xu, Academician Chang."

Xu Chuan nodded, as if to say hello, and quickly asked, "How are the four astronauts on Mars?"

Hearing this, Professor Zhao Ming did not waste time and quickly said, "I can only say that from the basic physical examination report data they sent back, there is no problem with their current physical health."

"But from the temperature test report, the body temperature of the four astronauts did rise a day ago."

"However, considering the weightless environment in outer space and the fact that they have been on the space shuttle for more than two months, the body temperature has risen. It may be normal for the four astronauts to be infected with Martian microorganisms. "

Xu Chuan: "What about the excrement test report? What is the probability of them being infected with those Martian microorganisms?"

On the side, Professor Chen Yunze, a microbial medicine expert, said: "If we look at the excrement test report, the probability of infection is relatively high. According to my personal speculation, the probability may reach more than 85%. "

"However, judging from the blood test report, the probability of the four astronauts being infected with Martian microorganisms is extremely low. Because their blood tests have not found any abnormalities for the time being. "

Hearing this answer, Xu Chuan and Chang Huaxiang frowned subconsciously.

"What do you think it might be?"

Chen Yunze answered without hesitation: "Parasitism or symbiosis."

After a slight pause, he added a description: "From the current physical examination data, the greatest possibility is microorganisms similar to Enterobacter and Enterococcus."

Hearing this, Xu Chuan breathed a sigh of relief and said: "That is to say, those Martian microorganisms may be harmless to humans?"

He still knew about the Enterobacter that parasitizes in the human intestine. It is a type of bacteria that assists human digestion.

Standing opposite, Professor Chen Yunze shook his head and said, "Not necessarily."

"The relationship between the human body and intestinal symbiotic bacteria is very complicated."

"Simply speaking, it can be divided into three categories. The first category is deep membrane flora, that is, probiotics. They are beneficial to the human body and are indispensable to the human body. Under normal circumstances, they are dominant flora, with protective, nutritional, and immune regulation functions."

"The second category is surface conditional pathogens, which are the microorganisms such as Enterobacter and Enterococcus that I just mentioned."

"When the human body is healthy and the intestinal flora is balanced, these bacteria will not cause harm to the human body."

"But when the intestinal flora is imbalanced, they will attack the human body and cause various types of diseases."

"Finally, there is another type, middle-layer pathogens."

"As the name suggests, they are generally harmful to the human body and can cause diseases, such as Proteus, Pseudomonas, and Clostridium perfringens."

"At present, we cannot determine which category the Martian microorganisms that may parasitize or coexist on the four astronauts belong to."
