Five Hundred and Thirty-Nine, the First Day of the Moon

The melodious music sounded, Ye Han rubbed his half-dream eyes, got up with his arms propped up, rubbed his face soberly, got out of bed in slow motion, stretched his arms and stretched his waist.

Sensing Ye Han's movement, the lights on the cabin roof automatically turned on, casting a soft light. Ye Han looked at the bulkhead for the first time, and the multi-function detector embedded in the bulkhead displayed the real-time temperature, humidity, pressure and air composition in the living cabin. After confirming that all the values ​​were within the normal range, he couldn't help feeling relieved tone.

This kind of multifunctional detector can be seen everywhere in the functional cabin. Once the environment in the cabin is abnormal, the environmental maintenance system will immediately send out a special alarm sound to remind the people 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 cabin. Not to mention the other side, the cost of sending astronauts to the moon is an astronomical sum. Losing any one person means Billions of dollars have been wasted, and necessary safety measures must be taken.

Ye Han's bedroom is very small. After unfolding the single bed, there is only half a square meter of space to settle down.

Just click on the bulkhead, and the air extraction system extracts the air in the single bed, making more space.

Sitting on the half-shrunk bed, I reached out to open the storage cabinet on the bulkhead, and the door that opened downwards turned into a small desk.

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

The mobile phone is a communication tool distributed to the astronauts. The communication equipment of the temporary base on the moon can be used as a transfer station to connect the signal 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, you can directly dial and make calls.

Due to many reasons such as too far away, signal loss and signal interference, 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 directly talk 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 other departments restrict astronauts from using mobile phones, but that the temporary base on the moon is not only located at the pole of the moon, but also inside a cratered crater, surrounded by mountains several kilometers high on all sides, and the communication signal between the temporary base and the earth is blocked. The crater is obstructed, and there is no way to communicate directly with the earth. .

The solution to this problem is a moon-orbiting satellite released by Sky-1 when it arrives at the moon. The moon-circling period of this satellite is 16 hours. Only the satellite flies out of the crater to act as a transfer station.

Only when the moon is on the side can the base establish direct contact with the ground.

The time limit for each satellite to appear is about three hours, and if this time is staggered, it will take another dozen hours to re-establish contact with the ground.

Limited to the current conditions, the earth and the moon can only endure intermittent communication environment. In order to solve this problem, Aerospace-2 will carry several satellites and release all the satellites one by one to form a communication network over the moon. At that time, it will be able to communicate with the ground. Establish an all-weather uninterrupted communication link to completely solve the problem of difficult communication.

But right now Ye Han still has to endure the intermittent communication. He didn't dare to be negligent, so he quickly clicked on the phone. Bai Xiaoting appeared on the screen and said with a smile: "Ye Han, are you alright? I think you can't stand it anymore, when the base is built in the future, I will definitely be the first to submit an application..."

Bai Xiaoting talked nonsense nonsense, but Ye Han listened to it with great interest, and didn't think to check the time until the video was over.

The time when the video was sent out was nine hours ago, at about nine o'clock in the evening on the ground.

Before the signal was cut off, Ye Han hurriedly recorded a video and sent it back, without mentioning any difficulties, and only said good things.

Although Ye Han knew very well that Bai Xiaoting understood the situation of the moon, he just made up such a self-deceiving statement and sent it back. As for whether Bai Xiaoting believed it or not, it was not in Ye Han's consideration at all. It's nothing else, it's just good news and not bad news. Even if Bai Xiaoting doesn't believe it, what if she can still go to the moon?

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

The environment on the surface of the moon is harsh. It is not easy to build a temporary base here. The cost of sending various materials to the moon is an astronomical figure that ordinary people dare not even imagine. The living space in the temporary base is no longer usable. An inch of land is an inch of gold, and it is basically an inch of land and an inch of gold.

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

But also because of the harsh environment on the surface of the moon, once the living module fails, it is likely to cause casualties. If everyone lives together, it will wipe out the entire army, and it will be a devastating blow to the Moon Palace project.

On the contrary, if everyone is separated, even if the living cabin fails, casualties can be kept to a minimum.

Again, the cost of sending an astronaut to the moon is too high, 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 at the same time. Ye Han was close to the water tower, and rushed in first, laughing triumphantly.

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

"Understood!" Ye Han quickly took off the gravity pajamas, and the whole person immediately relaxed a lot,

The gravity on the moon is too low, and the first-time astronauts will use too much force if they don't pay attention. Even an ordinary movement, if they are not careful, they will fall out due to excessive force.

Moreover, the microgravity environment brings not only a problem of adaptation or not, astronauts will also suffer from space sickness due to too low gravity!

Human bones and muscles are evolved to resist the gravity of the earth, and the state of weightlessness will lead to bone and muscle degeneration. Astronauts stay in space for a month, and the amount of bone loss is between 1% and 2%. Muscle loss was even more severe, averaging five percent per week.

The Moon's microgravity environment would cause the same thing, only at a slightly slower rate.

If things go on like this, all astronauts will never return to the earth in the future, even if they reluctantly go back, they will be second-class crippled lives.

But it’s not impossible. The astronauts in the space station use exercise to reduce the loss of bones and muscles. The method used by the moon base is to wear gravity suits!

This thing is designed for lunar astronauts on the ground. Its function is to increase the weight of the astronauts, so that the body weight of the lunar astronauts is equal to that of the earth, so as to avoid the loss of bones and muscles.
