A big country of aerospace with black technology

In the vastness of space, in the vast expanse.

Two space stations weighing tens of tons fly at high speed.

The centrifugal force caused by high-speed rotation resists gravity.

Liu Yang floated in the air and gently fixed his feet on the bulkhead.

Within the space station, strictly speaking.

There is no distinction between up and down.

On Earth, due to the influence of gravity, it is easy to tell up and down.

But inside the space station, if you ignore the hints of items on the bulkhead.

It is difficult to tell the difference between up and down through physical sensations.

Even on the ground, there's a lot of training.

There are still difficulties.

Therefore, there are a lot of psychological implications within the space station.

Tell them there is a difference between up and down.

The microwave heating caused a lot of hot steam to come out of the small pot.

Food that has been prepared on the ground and kept fresh through technical means.

Under heating, it emits an attractive aroma.

The third generation of space food has a much richer variety than the previous two generations.

Finally, there are dozens of dishes with different flavors.

These dishes are all chosen independently by the astronauts.

When the cargo spacecraft went up to the sky before, they had already gone up to the sky together.

The purpose is to meet the dietary needs of astronauts.

Life in space is boring and boring.

It is necessary to get a little comfort from delicious food.

"smell good."

After starting to eat, Liu Wang couldn't help but say.

These dishes are basically chef-level.

Even simply heating it up can make people salivate.

"Hurry up and eat. Today's task is quite heavy."

Jing Haipeng, the crew leader, said very calmly.

Although this mission is very long, it also contains a lot of content.

They don't just need to complete numerous space experiments.

There are still many space station construction tasks to be carried out.

and several spacewalk missions.

Although this space station is not expected to be used for too long.

However, for the consideration of future large-scale space stations, many experiments still need to be carried out.

For example, they are about to conduct a manual docking experiment on a cargo spacecraft.

Connected twice before.

Whether it is the docking of cargo spacecraft or the docking of manned spacecraft.

All are automatically connected.

And all were successful.

However, you still have to consider the situation where automatic docking cannot be used or fails.

This requires manual docking.

In addition, they will also conduct an extravehicular walk in the past two days.

Install a pair of new solar panels for the Tiangong-1 core module.

The current core module of Tiangong-1 is not yet equipped with high-precision robotic arms outside the cabin.

This kind of delicate work still needs to be done manually by astronauts.

After eating, several people cleaned the tableware they used with water polo.

There are not as many stains on tableware as there are on earth.

Clean the water polo, wrap the tableware, and then absorb it away.

This water will pass through the water circulation system.

Reuse later.

After finishing the meal, the first thing to do was to launch the survey telescope.

The survey telescope has a small battery pack and a pair of small solar panels.

Estimated service life, three years.

The survey telescope is used by the National Astronomical Observatory.

They've designed a whole host of tasks for the telescope.

Including, but not limited to, missions such as inner-solar planet observation, Milky Way star observation, deep space galaxy observation, etc.

In the experimental cabin, the survey telescope is being unpacked.

After that, it will be launched outside the cabin through the launch channel in the experimental cabin.

This technology is already relatively mature.

During the last manned flight, a small accompanying satellite was launched.

The principles are the same on both sides.

It is more reliable to fly such high-precision experimental equipment from the space station.

Compared to being launched directly into space via a rocket.

Flying from the space station reduces a lot of risks.

"The experimental cabin launch channel has completed preparations for launch."

After the unpacking is completed, prepare while contacting the ground command center.

Because the survey telescope belongs to the National Taiwan Radio and Television Station.

Therefore, they also have a lot of personnel working in the flight control center.

After stuffing the cylindrical folding telescope into the launch channel.

"Preparations for launch are complete, please give instructions."

Radio waves travel across space, transmitting commands into the vastness of space.

"Approval for launch mission."

In the launch tube, driven by high-pressure gas.

The survey telescope assembly flew away from the space station at an extremely high relative speed.

The current height of the space station is 380 kilometers, and the working height of the telescope is also here.

After the launch is completed, the survey telescope has little to do with the space station.

The ground control center will have specialized personnel to conduct detailed tracking of the telescope's subsequent flight status and its own situation.

In your mind, cross this task off.

A few people took a short rest.

The release process just now was not so easy.

Although inside the space station, due to weightlessness, the telescope will not be as heavy as it is on the ground.

But with just a slight push, it will fly to the top of the cabin.

People must control their own strength to accurately push the telescope into the launch tube.

The test of muscle strength is still very big.

"The next task is the biological laboratory."

After resting, Liu Yang began to operate the equipment in the biology laboratory.

An important task of their trip is "DNA sequencing in microgravity".

This is a new field of science, space genetics.

Before this, although some people had completed experiments on mice in space.

However, due to technical limitations, no one has yet conducted DNA sequencing.

This time, their experimental cabin carried a sequencer.

This is a device the size of a human head.

It is capable of applying electrical current through nanopores.

When the liquid containing the test sample flows through the detector.

Different DNA molecules will cause different current changes.

Through these current changes, organisms with this genetic sequence can be identified.

The crew prepared several different DNA samples in advance.

There are mice, monkeys, rabbits, bacteria, viruses, etc.

When Liu Yang was conducting DNA sequencing experiments inside the space station.

The ground experiment team will test DNA samples collected from the same mother.

Used to calibrate the accuracy of this DNA tester.

This technology is mainly used to identify microbial communities within the space station.

Screen them to see if they threaten the lives of astronauts.

If microorganisms are found, they may have a negative impact on the astronauts' living environment.

The ground medical team will advise them to take antibiotics and clean themselves up.

Of course, in addition to applications in the space station.

This technology is mainly used in the future.

For astronauts who stay on the space station for extremely long periods of time.

This will ensure their good health.

Because the future space station standby time will be measured in years.

"The first thing to do is to sequence the mouse gene."

Liu Yang's feet were not touching the ground and he was floating in the space station.

While comparing the operating procedures on the tablet in front of him, he performed manual operations.

The samples in the genetic sample box pass through the detector.

Caused changes in current, after identification.

It was shown on the monitor that this was a mouse sample.

The success of the first test sample made Liu Yang, the operator, a little happy.

At the same time, another experiment was also being carried out in the experimental cabin.

During the last manned flight, vegetable planting experiments were conducted on an experimental basis.

That time I grew simpler microgreens.

Not only is the planting time short, but the environmental requirements are relatively simple.

And this time, they are going to experimentally grow a crop that is very important to the Chinese people.

Rice!

As an important food crop for Chinese people for thousands of years.

For many people, it is an essential food staple.

This time they will start cultivating rice from seedlings.

The entire process until the rice is harvested.

This is a huge undertaking.

It is different from green vegetables, which are relatively simple to grow.

Rice has very strict environmental requirements.

Different stages have different requirements for water volume.

Now, Liu Wang is taking the first step of cultivation.

Germination.

If germination can be successful, it will be for everyone.

Even if it was a huge success.

Of course, it would be great if the entire growth cycle can be completed smoothly.

After completing the germination operation according to the guidance of ground agriculture experts.

Liu Wang couldn't help but exhale.

Germination requires a series of operations on the small rice.

The level of precision is still very high.

It is comparable to embroidering on rice grains.

It’s not just the astronauts’ arm power control accuracy that’s a test.

for the human spirit.

It is also a very severe test.

Come to the living cabin and take a short rest.

Liu Wang looked through the transparent porthole of the Tiangong-1 core module.

Look toward the Earth.

Their current height is not very high.

It is not possible to take in the entire earth.

But you can also see a large part of the earth.

They are now flying in the illuminated area.

Over the Pacific Ocean.

For the country, it is early morning.

You can see a not particularly obvious dividing line between black and white.

In addition, you can still see many bright lights in the dark area.

Just when Liu Wang was admiring the beautiful scenery of space.

A more conspicuous orange target slowly came into view.

"Is this the International Space Station?"

Liu Wang couldn't help mumbling to himself.

Jing Haipeng, who had just come out of the cargo spacecraft, also came to his side and took a look.

"It does appear to be the International Space Station."

The International Space Station began to enter the construction stage four or five years ago.

At that time, there was still a period of debate in the country.

Do you want to join the International Space Station project?

Of course, the controversy later came to an end.

Because they simply do not agree with us joining the International Space Station.

Therefore, we have made every effort to build our own space station.

It is actually not that easy to see the International Space Station from a distance of about twenty kilometers.

If it weren't for the fact that the space station produced a lot of reflections due to the lighting.

Liu Wang probably couldn't even see him.

At this stage, the International Space Station is still undergoing the first round of construction work.

The final state of the Hereafter has not yet been reached.

In terms of tonnage, it is actually not much different from the tonnage of Tiangong-1.

"Their orbit is lower than ours."

"In order to facilitate docking, their construction work is still in progress, and the number of dockings is relatively high."

The height of the International Space Station flying at this time is much lower than that of the Tiangong-1 Space Station.

This is also the reason why Liu Wang can detect it when he looks at the earth.

If the flight orbit is higher than them, it will not be so easy to detect it.

Tiangong-1 has not yet conducted a large number of docking missions.

So the flight altitude should be higher.

Of course, Tiangong-1 itself is only a transitional space station.

Currently, China is designing and manufacturing a truly large space station core module.

The weight alone has reached the unprecedented 100-ton level!

The final complete body will reach the kiloton level!

Truly, the largest man-made miracle in space in human history!

"What are you looking at here?"

By this time, Liu Yang had also completed sequencing different types of DNA.

The accuracy of the sequencer currently reaches 100%.

Samples with different DNAs can be detected.

Although the accuracy may not be particularly high for different sample variants.

But at the current stage, it is only detecting germs, viruses, etc. on the human body.

That's enough.

"The International Space Station that just flew by."

Liu Wang pointed at the space station that was almost flying far ahead of them and said.

"Why does their flying posture look weird?"

After Liu Yang stared for a few seconds, he said with some confusion.

They were the first astronauts.

Have a certain understanding of all aspects of knowledge.

Especially as the first astronauts to go to the space station.

They have all systematically studied the contents of the space station.

So after seeing the flight status of the International Space Station.

Liu Yang had such a question.

"Maybe they are different from our space station and are like this?"

Jing Haipeng thought for a while and then said.

If you think about it this way, there's nothing wrong with it.

After all, there are indeed big differences between the two space stations.

There is a big difference in structure between the two.

"Maybe, but this has nothing to do with us."

Liu Wang shrugged his shoulders indifferently and said.

It's not like they were involved in the International Space Station, no matter what went wrong.

It's none of their business.

However, the development of things is often beyond people's expectations.

Whether it is the astronauts in Tiangong-1 or the staff of the ground command center.

Didn't even think of it.

At this time, the International Space Station was about to explode.

Their space station has a very serious problem with its flight attitude control!

A large amount of information exchange occurred in an instant between the International Space Station and the Houston control center.

Control Center in Houston wants to know what is happening on the International Space Station.

On the International Space Station, astronauts want to know how to save themselves! (End of chapter)
