The vastness of space, in the vastness of the vast.

Two space stations weighing tens of tons, flying at high speed.

The centrifugal force brought about by high-speed rotation resists gravity.

Liu Yang floated in the air, gently fixing his feet to the bulkhead.

Inside the space station, strictly speaking.

There is no upper or lower.

On Earth, under the influence of gravity, it is easy to distinguish between up and down.

However, inside the space station, if you ignore the hints of items on the bulkheads.

It is difficult to distinguish between the upper and lower levels by feeling them physically.

Even on the ground, with a lot of training.

Difficulties remain.

So, there's a lot of psychological cues inside the space station.

Tell them that there is a difference between up and down.

Microwave heating, so that a lot of heat comes out of the small pot.

In the ground has been made, by technical means to preserve the freshness of the food.

When heated, it gives off an enticing aroma.

The third generation of aerospace food is much richer than the previous two generations.

Finally, we have dozens of dishes with different flavors.

These dishes were all independently selected by the astronauts.

When the cargo spacecraft went to the sky before, they were already in the sky together.

In order to meet the dietary needs of astronauts.

Life in space is boring and boring.

It's a necessity to be able to get a little comfort from good food.

"It smells so good."

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

These dishes are basically chef-level.

Even simple heating can make people salivate.

"Hurry up and eat, the task is quite heavy today."

Jing Haipeng, as the leader of the crew group, said very calmly.

Although this mission is very long, the content of the mission is also very large.

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

There are still a lot of space station construction tasks to be carried out.

and several spacewalk missions.

Although the space station will not be used for too long.

However, in order to consider the future large-scale space station, there are still many experiments to be carried out.

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

Docked twice before.

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

It's all auto-docking.

And all were successful.

However, it is still important to take into account the fact that the automatic docking is not available, or it fails.

This necessitates the use of manual docking.

In addition to this, they will have to go on an extravehicular walk for the next two days.

For the Tiangong-1 core module, install a pair of new solar panels.

The current Tiangong-1 core module has not yet been able to equip an extravehicular high-precision robotic arm.

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

After eating, several people washed their utensils with water balloons.

There are not as many stains on dishes as there are on the planet.

Clean the water balloon, wrap the utensils, and then absorb it.

This water passes through the water circulation system.

Reuse in the future.

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

The Survey Telescope, which has a small battery pack and a pair of small solar panels.

Estimated service life, three years.

The unit of use of the survey telescope is the National Astronomical Observatories.

They have designed a whole bunch of tasks for telescopes.

Including but not limited to, intrasystem planet observation, Milky Way star observation, deep sky galaxy observation, etc.

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

After that, it will be launched outside the capsule through the launch channel inside the experimental module.

This technology is already relatively mature.

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

The principle is the same on both sides.

From the space station, it is more reliable to fly such high-precision experimental equipment.

This is compared to launching directly into space by rocket.

The space station was released, reducing a lot of risks.

"The launch channel of the experimental module has completed pre-launch preparations."

After the unpacking was completed, I was in contact with the ground command center while preparing.

Because the owner of the survey telescope is Guotai.

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

After the cylindrical folding telescope is tucked into the emission channel.

"Preparations for launch are complete, please instruct."

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

"Approval for the launch mission."

In the launch pipe, driven by high-pressure gases.

The Sky Survey Telescope component flew away from the space station at an extremely high relative velocity.

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

After the launch, the Sky Survey Telescope has little to do with the space station.

In the ground control center, there will be special personnel to track the subsequent flight status of the telescope and its own situation in detail.

In my own mind, cross out this task.

A few people took a short break.

The process of flying 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 a single push, it flies to the roof.

People have to control their power to be able to push the telescope into the launch pipeline with precision.

For the test of muscle strength, it is still very big.

"The next task is the biological laboratory."

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

One of the most important tasks of their trip was "DNA sequencing in microgravity".

It's a whole new field of science, space genetics.

Before that, someone had done a guinea pig experiment in space.

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

This time, they carried a sequencer in the chamber.

It's a device the size of a human head.

It is capable of applying an electric current through the nanopores.

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

Different DNA molecules will cause different electrical changes.

Through these changes in electrical currents, it is possible to identify organisms with such genetic sequences.

The crew prepared several different DNA samples in advance.

There are mice, monkeys, rabbits, bacteria, viruses, and so on.

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

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

It is used to correct the accuracy of this DNA tester.

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

Determine if they are a threat to the lives of astronauts.

If microorganisms are found, they may have an adverse effect on the living environment of astronauts.

The medical team on the ground will advise them to take antibiotics and take their own cleansing.

Except, of course, for applications in the space station.

This technology is mainly used in the future.

For astronauts who have been on the space station for a long 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 genes of the mice."

Liu Yang didn't touch the ground with his feet on the ground, floating in the space station.

Perform manual operations while comparing the operation process on the tablet in front of you.

The sample inside the genetic sample box passes through the detector.

caused a change in the current, after discernment.

On the monitor, it was shown that this was a sample of mice.

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

At the same time, another experiment was being carried out inside the experimental chamber.

On the last manned flight, an experiment was carried out on vegetable planting.

This time it was a small, simple vegetable.

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

This time, they are going to experiment with a crop that is very important to the Chinese people.

Rice!

It has been an important food crop for thousands of years.

For many people, it is an indispensable staple food.

This time, they will start cultivating the rice from the seedling level.

All the way to the end of the rice harvest.

This is a huge amount of work.

It is different from small greens that grow more easily.

Rice has very strict environmental requirements.

Different stages have different requirements for water volume.

And now, Liu Wang is taking the first step in cultivation.

Germination.

If germination can be successful, for everyone.

Even if it was a great success.

Of course, it would be great if the whole growth cycle could be completed smoothly.

After the germination operation was completed under the guidance of experts in ground agriculture.

Liu Wang couldn't help but exhale.

Germination requires a series of operations on small rice.

The level of detail is still very high.

It's like embroidering on a grain of rice.

It's not just the astronaut's arm strength, and the precision control is a test.

For the human spirit.

It was also a very severe test.

Come inside the living pod and take a break.

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

Look to the Earth.

Their height is not very high now.

It is not possible to see the whole planet.

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

They are now flying in the Illuminated Zone.

Over the Pacific Ocean.

For the country, it is early in the morning.

A not-so-obvious black-and-white dividing line can be seen.

On top of that, you can see a lot of bright lights in the dark area.

Just when Liu Wang was enjoying the beauty of space.

A more conspicuous orange target slowly came into view.

"Is this the International Space Station?"

Liu Wang couldn't help muttering to himself.

Jing Haipeng, who had just come out of the cargo spaceship on the side, also came to his side to take a few looks.

"It looks like it's the International Space Station."

The International Space Station, which began to enter the construction phase four or five years ago.

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

Whether or not to be part of the ISS project.

Of course, the controversy ended in vain.

Because, they simply don't agree with us joining the ISS.

So, we have to go all out to build our own space station.

Separated by about 20 kilometers, the ISS is not so easy to see.

If it weren't for the light on the space station, there would be a lot of reflections.

Liu Wang estimated that he couldn't even see him.

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

It has not yet reached the final state of the Hereafter.

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

"Their orbit is a little lower than ours."

"In order to facilitate docking, their construction work is still ongoing, and there are more docking times."

At this time, the International Space Station flies at an altitude much lower than that of the Tiangong-1 space station.

This is also the reason why Liu Wang was able to spot it when he looked at the earth.

If the flight trajectory is higher than theirs, it is not so easy to spot it.

Tiangong-1 has not yet carried out a large number of docking tasks.

So the flight altitude should be a little higher.

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

At present, a truly large space station core module is being designed and manufactured in China.

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

In the end, it will reach the 1,000-ton level!

True, the largest man-made wonder in space ever!

"What are you looking at here?"

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

The sequencer is now 100 percent accurate.

Samples with different DNA can be detected.

Although it may not be particularly accurate for different sample variants.

But at this stage, it is only a detection of germs, viruses, and so on on on the human body.

Enough is enough.

"The International Space Station that just flew past."

Liu Wang pointed to the space station, which was about to fly far in front of them, and said.

"How do they look weird in their flight attitude?"

Liu Yang stared at it for a few seconds, and then said with some doubts.

They served as the first astronauts.

There is a certain understanding of all aspects of knowledge.

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

All of them have systematically studied the content of the space station.

So after seeing the flight status of the ISS.

Liu Yang had such a question.

"Maybe they're different from our space station, that's what they are?"

Jing Haipeng said after thinking for a while.

Thinking about it this way, there's nothing wrong with that.

After all, there is indeed a big difference between the two space stations.

There is a big difference in the structure between the two.

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

Liu Wang shrugged his shoulders a little indifferently and said.

The ISS is again without them, no matter what the problem is.

It's none of their business.

However, the development of things is often unexpected.

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

Didn't expect it.

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

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

Between the ISS and the Houston control center, a huge amount of information was exchanged in an instant.

Houston Control, wants to know what's going on on the ISS.

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