The vast universe is vast, and the current observable universe is about 93 billion light-years.

Since the birth of the universe, the universe has been changing all the time, and human beings' understanding of the universe is very limited.

The number of galaxies in the universe is huge, an infinite number, and there are about 125 billion galaxies observed by humans so far.

"We all know that the planet we are on belongs to the solar system, and the solar system belongs to the Milky Way."

"There are countless galaxies in the universe that are the same size as the Milky Way, and they are also self-contained, and they exist in places that we can't observe."

"So now please recall what you have learned, is our planet a planet or a star? What is the difference between a planet and a star? ”

"What is the relationship between the mysterious existence of the universe, black holes and dark matter?"

“……”

After an intensive indoctrination of the basic knowledge of the universe, everyone now has various celestial "stars" shining brightly in their heads.

"Okay, that's all for this class first, everyone will check and fill in the gaps by themselves when they go back, consolidate more, discuss with each other if you don't understand, and you can also come and ask me at any time."

The space agency teacher who was responsible for "making up" the basic knowledge of the universe for the players left a full board of books and left the classroom with the books.

"Wow, can you listen to you. How I feel like I'm listening to a book from heaven. ”

Lan Lan stretched, and then leaned on Tang Qinqin with a yawn and no bones.

"You're right, isn't it the Book of Heaven? Tell heavenly stories. How can you possibly understand. ”

Yamanai suddenly poked his head out and bared his teeth.

"It's stinky and lazy, isn't it itchy again, you come over and my sister loosens it for you."

"Sister yet, I want to be my sister, let's be born early in the next life."

The two of them were talking like chickens, and the atmosphere was harmonious.

Anyone with a discerning eye can see the unspeakable affection between the two people who are bickering with each other.

"Let's go, let's go back to check in online first, and then we have to be busy."

Tang Qinqin quietly withdrew from the "battlefield" with Mengru in his arms, thinking about the next plan along the way.

……

Players can get space vehicle fragments, spacesuit fragments, etc. through the online check-in of the quiz game every day, and the 999+ fragments can be combined into real primary space vehicles and spacesuits, and the accumulation of double fragments can upgrade the primary aerospace equipment to a higher level, and so on, until the full level.

The types of aerospace equipment that can be obtained by punching in are different, and you can choose according to your preferences, so players are very active and looking forward to the daily check-in tasks, counting the number of fragments in their hands every day, calculating how long it will take to synthesize real aerospace equipment, and sometimes even eager to ignore the check-in limit of once a day and continue to invest in the check-in task again.

The country is also happy to see this, they are very interested in the production of games, maybe they can take this opportunity to study and learn, break through the bottleneck of today's aerospace research and development, and make aerospace technology to a higher level.

After playing the card and harvesting today's space equipment fragments, Tang Qinqin immediately entered the "weightlessness simulation training" in the game.

Astronaut training generally includes physical training, aerospace environment adaptation training, psychological training, basic theory training, aerospace professional and technical training, flight procedures and mission simulation training, etc., and any astronaut who is qualified to enter space must go through a very strict assessment.

The "weightlessness simulation training" she is currently conducting is one of the aerospace environment adaptation training.

In fact, Tang Qinqin is more willing to call it a "spacewalk" than "weightlessness simulation training".

In addition to the discomfort at the beginning, as the training time has grown, she can now move freely in a weightless environment, and even enjoys the feeling of floating in invisible seawater.

Seriously, she can't wait to build her own spacecraft and fly it into the blue sky and out of the solar system.

I don't know if I don't know if I don't know it, but as soon as I step into this threshold, I know why astronaut training is called "devil training".

This shocking devil training includes: underwater weight-bearing training, in which astronauts carry 120-kilogram equipment on their backs for up to four hours of non-stop training underwater, and when the underwater training is over, the astronauts' hands are shaking when they eat.

At the end of a training session, you will lose one to two kilograms.

The second is vestibular function training, in which astronauts are blindfolded and sit on a swivel chair to do 360-degree rapid rotation, and the swivel chair will swing up and down in the process, simulating the state of losing space orientation in the universe, which is used to train astronauts' anti-motion sickness ability.

There are also stress response training, hypoxic endurance training in the stress test chamber, centrifuge overweight endurance training (recognized as the most painful training), 72-hour sleep deprivation experiment (recognized as the most difficult training for astronauts), silence and loneliness training, also known as isolation psychological training, in a noisy and vibration environment, endure uninterrupted intrusion, observe whether you are irritable, and the last item is weightlessness training.

And these training programs are necessary for gamers who are preparing to step into the universe for the exploration of the stars and seas.

If you want to take an extraordinary path, you must also suffer what others can't bear.

During the training period, the players, like normal astronauts, will hold a red alarm in their hands, once the training exceeds the physical load or there are other emergencies, they can call a stop in time for emergency treatment.

Since the establishment of the Huaxia Astronaut Brigade, for more than 20 years, no astronaut has ever pressed the alarm device, and this record has no rival in the world.

The Chinese nation's spirit of constantly challenging oneself and not being afraid of hardship and tiredness, working hard and fighting bravely, rooted in the bone marrow, is vividly embodied in the astronaut brigade.

China's manned space flight started late, everything was groundbreaking work, and the unknown hardships in the whole process could not be expressed in words.

At present, Tang Qinqin has only preliminarily passed the last weightless training, and other more serious challenges are still waiting for her to try and face.

At this time, her admiration for the staff of the China National Space Administration is particularly strong, this is a group of brave warriors who have the courage to constantly challenge themselves and explore and conquer the sea of stars on behalf of the Chinese nation, and she is fortunate to have the opportunity to become one of them one day in the future, representing the motherland and compatriots to go out to the universe to get infinitely close to the vast starry sky.
