In the cabin scene, Yuan Zifeng has now changed into a more casual cabin work clothes. Wearing a short-sleeved shirt on the upper body and a pair of casual pants on the lower body, it looks no different from the clothes we usually wear.

This is more of a Western cabin clothing style rather than a specialized blue cabin suit like ours.

Yuan Zifeng wears a smart watch on his wrist, which can actually be called a personal data terminal. It is the astronaut's personal information processing center. Generally speaking, it will be used with two wearable devices, one is an intelligent voice assistant, and astronauts wear it to conduct air-to-ground conversations.

The other one is smart AR glasses. Through the virtual interaction platform of this AR glasses, astronauts can control relevant data information in real time.

Of course, it can also be used alone.

However, what Yuan Zifeng was wearing at this time was an intelligent voice assistant, because although the Walker 4 manned return capsule was relatively spacious, it was more than enough to accommodate one person. However, compared with the huge space in the space station, this space in the spacecraft is really too small, so the role that smart AR glasses can play is relatively limited. Therefore, for convenience, Yuan Zifeng wore a smart voice assistant.

At this moment, Yuan Zifeng was unpacking related packages in a semi-floating state. He will stay in the air for dozens of hours, so the relevant living materials must be disassembled and sorted for later use.

These supplies include some scientific research materials, which cannot be stacked in the open. Instead, they are carefully packaged and fixed on some shelves behind the manned return capsule. So now Yuan Zifeng's job is to take down these fixed packages and dismantle them.

Upon hearing Wu Hao's inquiry, Yu Chengwu smiled and replied: "Currently, the astronauts are dismantling and sorting out the packages of living and scientific research supplies on the spacecraft in order to carry out normal life and work."

"Have you had breakfast?" Wu Hao asked, looking at the big screen.

"Not yet. We just communicated with the astronaut and he wanted to wait until the materials are sorted out before eating and resting." Yu Chengwu said helplessly.

"It's a good thing to work actively and conscientiously, but you still have to strictly follow the astronaut space work and rest system." As he said that, Wu Hao looked at Zhou Chengfang who was standing aside.

Zhou Chengfang nodded after hearing what he said: "We have carefully designed the astronauts' meals, nutrition, and work schedules. Unauthorized changes may affect the astronauts' physical distribution, thereby affecting subsequent related work."

After listening to Zhou Chengfang's words, Wu Hao nodded and then looked at Yu Chengwu and said: "We must pay attention to these details in the future and make arrangements. I want to talk to the astronaut."

"Okay." After hearing Wu Hao's words, Yu Chengwu nodded in agreement. This was indeed something he did wrong. Although it was just a small matter, everything must be done in a methodical manner and should not be done casually, especially when performing tasks. Many failures and accidents are caused by a little negligence and carelessness.

"Walker 4, this is the South China Sea. Please reply if you hear me."

"Nanhai, this is Walker 4." In the video, after Yuan Zifeng heard the call, he immediately stopped, floated in front of the camera, and answered.

"Walker 4, Mr. Wu wants to talk to you."

During this preparation process, Wu Hao also found a smart voice assistant, put it on his ear, then looked at Yuan Zifeng in the video and said with a smile: "Zifeng, how do you feel now?"

"It feels good." Yuan Zifeng responded, then said with a smile on his face: "The internal space of the spacecraft is very large, so it is very convenient for me to move. Compared with the hardships that my predecessors have endured, the environment I am in now The living and working conditions are much better.

Thank you Mr. Wu for giving me such a valuable opportunity to experience a special space journey. "

Haha, Wu Hao laughed when he heard this: "Actually, we should thank you for your trust and entrusting your life to us. Please rest assured that we will send you to the ground safely and smoothly."

"I have no doubt about the performance and safety of the Walker 4 spacecraft." Yuan Zifeng replied loudly.

Wu Hao looked at Yuan Zifeng in the video and smiled: "Okay, then I will wait for your victory and triumph.

Work is important, and so is life. Don't neglect your work and neglect your body. Eat on time and rest on time.

By the way, what are the plans for breakfast today? Wu Hao asked with a smile.

Hearing Wu Hao's words, how could Yuan Zifeng not understand the meaning of Wu Hao's words, so he responded with a smile, then took out a packaging bag from the side, then smiled at Wu Hao and said: "Today's breakfast is very good." It’s rich, including steamed buns, porridge, fruits, vegetables, and sausages.”

Yuan Zifeng showed it to them, and then placed the meal on the heater in the return capsule to heat it. The space inside the spacecraft's manned return capsule is limited and cannot accommodate a microwave oven, so only a food warmer can be placed.

As for the meals for the astronauts, they are actually specially ordered from the astronaut department. Compared with ordinary meals, these space meals are very demanding. In addition to being nutritious and healthy, the food must also taste delicious and there should be no food residues when eating, etc.

Because space is a microgravity environment, food residues will float in the air. Once inhaled into the lungs, it is easy to choke and even cause life-threatening consequences.

Therefore, the earliest astronaut meals were actually toothpaste-like liquid food that the astronauts squeezed to drink. Although it is considered nutritious and healthy, its taste is extremely poor and is not very popular among astronauts.

Especially in the weightless environment of space, and astronauts need to stay in a small space for a long time, it is easy to have some physical and psychological obstacles. Some astronauts may even have a weakened sense of taste and appetite due to some reasons. decline. And bad food will also increase the psychological burden on astronauts, resulting in some psychological diseases.

For example, the dehydrated vegetable packets in instant noodles were originally developed specifically for astronauts. The initial goal of scientific researchers in developing this dehydrated vegetable package was to enable astronauts in space to eat fresh and nutritious vegetables.

Of course their goal was achieved, but they ignored another question, whether the astronauts liked it or not. In fact, people don’t really buy into this kind of dehydrated vegetables.

Later, as scientists continued to understand and study the space environment and developed related technologies, especially food preparation and storage technologies, space meals gradually became more humane and enriched.

Nutritional health and fullness are no longer the main requirements for space food. The taste and texture of food have also become an important criterion for measuring the quality of space food. Up to now, engineers will also customize some meals that suit the eating habits of astronauts in space and deliver them to space.
