The melodious music sounded, Ye Han rubbed his half-dreaming eyes, got up with his arms propped up, rubbed his face and was sober and awake, got out of bed in slow motion, stretched his arms and stretched his waist. Pen, fun, pavilion www. biquge。 info

Sensing Ye Han's movements, the lights on the roof of the cabin automatically lit up, sprinkling a soft light. Ye Han looked at the bulkhead for the first time, and the multi-function detector embedded in the bulkhead showed the real-time temperature, humidity, pressure and air composition in the living module, and determined that all the values were within the normal range, and couldn't help but secretly breathe a sigh of relief.

This multi-functional detector can be seen everywhere in the function cabin, and once there is an abnormality in the cabin environment, the environmental maintenance system will immediately send out a special alarm sound to alert the personnel in the cabin to pay attention.

This is the lunar surface far away from the earth, any omission may cause the consequences of the destruction of the capsule and the death of people, not to mention the side, the cost of sending astronauts to the moon alone is an astronomical amount, the loss of any person, it means that billions of dollars have been lost, and the necessary safety measures must not be missing.

Ye Han's bedroom is very small, and after the single bed is unfolded, there is only half a square of space to settle in.

With a single press on the bulkhead, the extraction system draws the air out of the single bed, making more space.

Sitting on the half-shrunken bed, the probe opened the storage cabinet on the bulkhead, and the downward opening door turned into a small desk.

Ye Han took out a small mobile phone from the cabinet, and immediately smiled when he turned it on, the signal was full!

The mobile phone is a communication tool for astronauts, and the communication equipment of the temporary base on the moon can be used as a relay station to connect signals with the ground communication system, turning the mobile phones of all astronauts into a part of the earth communication network.

To put it bluntly, with this special mobile phone, it is possible to dial up the number directly.

Because of the distance, signal loss and signal interference and many other reasons, the sound quality of this thing is always unsatisfactory, and there is a delay of more than a second when speaking.

These are nothing, after all, being on the moon, it is very rare to be able to talk directly to relatives and friends, but what makes all astronauts unbearable is that this thing must be used for a limited time!

It's not that the ground command center or any other department restricts astronauts from using mobile phones, but that the temporary base of the moon is not only located at the pole of the moon, but also in the crater of the pit, surrounded by peaks up to several kilometers on all sides, and the communication signal between the temporary base and the earth is blocked by the crater, and there is no way to communicate directly with the earth.

The solution to this problem is a moon-orbiting satellite released by Kongtian-1 when it arrives on the moon, and the moon's orbital period is 16 hours.

The time limit for each satellite appearance is about three hours, and it takes another ten hours to re-establish contact with the ground during this staggered period.

In order to solve this problem, Kongtian-2 will carry several satellites, release all satellites in turn, and form a communication network over the moon, so that it can establish all-weather uninterrupted communication links with the ground and completely solve the problem of difficult communication.

But now Ye Han has to continue to endure intermittent communication, he didn't dare to slack off, and quickly clicked on the phone, Bai Xiaoting appeared on the screen, showed a smile and said, "Ye Han, are you okay?" It's only been a few days since I thought I couldn't stand it, and when the base is built in the future, I'll be the first to apply......"

Bai Xiaoting said a lot of nonsense that was not nutritious, but Ye Han listened to it with relish, and it was not until the end of the video that she remembered to take a look at the time.

The video was posted nine hours ago, and it was about 9 p.m. on the ground.

While the signal was still not broken, Ye Han hurriedly recorded a video and sent it back, without mentioning the difficulties, and saying all good things.

Although Ye Han knew very well that Bai Xiaoting knew about the situation on the moon, he insisted on making up such a self-deceptive sentence and sending it back, as for whether Bai Xiaoting believed it or not, it was not in Ye Han's consideration at all. Nothing else, just report good news and not bad news, even if Bai Xiaoting doesn't believe it, what if she can still run to the moon?

Putting down the phone, Ye Han opened the single-layer airtight door, left his small bedroom, and happened to meet Duan Zhiyang, who lived next door.

The surface environment of the moon is harsh, and it is not a simple matter to build a temporary base here, and the cost of sending all kinds of materials to the moon is an astronomical amount that ordinary people dare not think of.

In such a place, it is the most economical and economical arrangement for everyone to sleep in a dormitory.

However, also because of the harsh environment on the surface of the moon, once the living module fails, it is likely to cause casualties among the people in the cabin.

Conversely, by separating everyone from each other, even if the living module fails, casualties can be kept to a minimum.

Again, the cost of sending an astronaut to the moon is too high, and even with the strength of the country, it cannot afford such a loss.

As soon as the two of them met, they rushed to the bathroom in unison, Ye Han approached the water building, rushed in first, and laughed proudly.

Duan Zhiyang bared his teeth helplessly: "Hurry up!" ”

"Got it!" Ye Han quickly took off his gravity pajamas, and the whole person immediately felt a lot easier.

The gravity on the moon is too low, and the newcomers will use too much force if they don't pay attention to it, even if they make an ordinary action, they will fall out because of too much force.

And the microgravity environment brings not only the problem of adaptation, astronauts will also suffer from space sickness because of low gravity!

Human bones and muscles have evolved to fight the gravitational pull of the earth, and weightlessness can lead to bone and muscle deterioration, astronauts spend a month in space, the amount of bone loss is between one and two percent, and the loss of muscle is even more severe, with an average loss of five percent per week.

The same can be said for the Moon's microgravity environment, albeit at a slightly slower rate.

In the long run, all astronauts will not return to Earth in the future, and even if they reluctantly go back, they will be second-class cripples.

But it's not impossible, the astronauts on the space station use exercise methods to reduce the loss of bones and muscles, and the moon base uses the method of wearing gravity suits!

This thing is designed for lunar astronauts on the ground, and its function is to increase the weight of astronauts, so that the weight of the lunar astronauts' body is equal to the weight they hold on Earth, so as to avoid the loss of bones and muscles.
