"Space travel" is nearing the end, and the "God Thirteen" multiplier is dynamically updated in orbit

Today is space with you [Issue 1437]

recently

The Tianzhou-2 cargo spacecraft is completed

All the tasks of the core module assembly phase

Evacuation of the core cabin core module assembly

Will be re-entered into the atmosphere at the right time

Shenzhou 13 astronaut crew

"Space travel" is also nearing completion

Officially entered the "Countdown to Coming Home"

Previously

The Shenzhou 13 astronaut crew was successfully completed in orbit

The second lesson of the "Tiangong Classroom" of the Chinese space station

Some netizens said

This space lesson

Astronaut Zhai Zhigang's footage seems to be a little less

In fact

As the person in charge of this space lecture

The commander silently controls the big picture behind the camera

Look at it from another angle

While acting as a cameraman

The commander also personally "directed" it

The course of action of the speakers Wang Yaping and Ye Guangfu

It was very clearly organized

For this space lecture can be

Better inspire the majority of young people to continue to pursue the "scientific dream"

The passion for realizing the "space dream"

Astronauts carefully prepare and rehearse inside the space station

The three of them had a heated discussion on the specific details of the lecture

The ice piers in space are aided by Wang Yaping

Completed a beautiful "4A"

It's not just experimentation

All the details in the second lesson of "Tiangong Classroom"

Astronauts have long been familiar with it

Remember this scene?

Astronaut Ye Guangfu "cornice walking wall"

Introduce the use of the experimental cabinet in the space station

Where did Zhai Zhigang go?

It turned out that the commander was holding the lens in his hand and "flying close to the ground"

The "space photographer" really lives up to its name

In addition to space teaching

Crew at Shenzhou XII astronauts

On the basis of preliminary work

More than twenty scientific experiments on orbit have been completed

A number of important achievements have been achieved

These experiments revolve around new technologies for astronaut health monitoring

New scientific knowledge and new discoveries and data accumulation

A series of innovative studies have been completed

For the first time, spatial conditions were established

Long-term culture systems and cell models of cells

Utilize such systems and training models

Completed several internationally leading life science experiments

For example

It was observed for the first time

"Calcium signal flickering" of cardiomyocytes under weightless conditions

The kidney epithelial cells in the human urine

By way of genetic reprogramming

Transformed into stem cells with multiple functions

It is differentiated into cardiomyocytes

And fluoresces the protein

You can see the flickering process of the calcium signal during the contraction process

This is also the first time that the world has seen a weightless environment

The contraction process of cardiomyocytes

Take advantage of the gravity-sensitive properties of cardiomyocytes

Researchers make observations based on astronauts' in-orbit experiments

Compare cardiomyocytes in gravity conditions and

Shrinkage process and characteristics under weightless conditions

Better interpret the effects of weightlessness on the human body

Understand the characteristics of cardiovascular changes in astronaut weightless conditions

For the health of the masses, the regeneration and aging of human beings

Including human longevity and the occurrence of heart disease

Provides a very good experimental model

furthermore

Relying on the core cabin assembly

Mainland scientific researchers have also completed the first time in the world

Suspension culture experiment under long-term weightless conditions of skin stem cells

Ye Guangfu took out a "small box" from the experimental cabinet

Inside are the cells they have grown in space

During the month of cell survival

Astronauts repeatedly observe and study cells

and timed to provide for these cells

Nutrient solution Digestive juice, etc

This is a cellular study for long-term weightless conditions

Provides an important technology platform

Conduct such cell space experiments

It will help human beings to better understand life

Astronauts want to fly farther and healthier

With space medicine constantly acquired

New harvests and new understandings are inseparable

Only these gains and understandings are increasing

In order to better support astronauts to explore space

Recent

The "feel good" multiplier is actively preparing for the return

Before returning

What more preparations will they be doing?
