On-orbit testing
Shenzhou XIII astronauts, completed multiple on-orbit experimental missions, what did they find? When facing events such as the new crown epidemic and the Russian-Ukrainian conflict on the ground, have you forgotten that there are three national treasures in the sky, yes, they are the first three astronauts to spend the Spring Festival in space, namely: Zhai Zhigang, Wang Yaping, and Ye Guangfu.
Conduct life sciences
According to the news of the China Aerospace Manned Office, the mainland has established a long-term culture system and cell model of cells under space conditions for the first time under the condition of relying on the Chinese space station, and using such a system and culture model, scientific researchers have completed several internationally leading life science experiments, which will bring milestone significance to the future history of human spaceflight.
The importance of life
At this time, some people asked, why didn't the three astronauts appreciate the beautiful space, or try to discover something new, and choose to carry out life science engineering? In fact, people-oriented, in our socialist country embodied vividly.
In 2020, in the case of the new crown virus, lockdown and isolation, factory shutdown and suspension, the country still uses human life as the first guarantee to fight the virus in the case of huge losses of funds. As a result, with the efforts of all the Chinese people, we have successfully defeated the epidemic in more than three months.
Experiments on the space station are still the same, before we did not have a space station, a lot of scientific research has to rely on the data on the International Space Station, whether these data are detailed and accurate, is extremely important to our astronauts.
To know that unlike the earth, in the space weightless environment, the mother's womb adapts to gravity, in the vacuum environment, what subtle changes will occur in the body, which is very important, because this is an important guarantee for the health of astronauts.
Calcium signal flickers
With the efforts of the Thirteen members of God, we completed a series of life science experiments. The first is the flashing calcium signal of the cardiomyocytes. Chinese scientists said: For the first time in the world, we have realized the process of recombination of kidney epithelial cell genes, recombining cells into stem cells.
Then use stem cells to differentiate cardiomyocytes, yes, the cells on our hearts, and then edit a fluorescent protein to achieve the experiment of cardiomyocyte beat. As long as the heart muscle cells are beating, then we can observe it through the fluorescent protein.
The purpose of this study is to explore what kind of effects the human heart will have in a gravity-free vacuum environment, which is extremely important for astronauts.
Skin stem cell weightless suspension culture experiment
Another experiment is the skin stem cell weightless suspension culture experiment, which is also the first case completed internationally. By cultivating skin stem cells in a gravity-free environment and allowing them to survive and grow in a vacuum environment, our purpose is still to understand what effects and changes human skin stem cells will have in a gravity-free environment through this experiment.
This article summarizes
Scientists said: Life sciences are especially important for human space travel in the future, because space travel is usually an incomparably long, long-term gravity-free environment, what harm to the human body, we must understand.
Because although the mission time is obviously short, the time of future space missions such as planetary exploration may extend to several years or even longer. In the face of such a long space environment, we must know how long and how long gravity will affect the human body.
Health is the most important guarantee for astronauts, healthy astronauts can complete excellent tasks, and only healthy astronauts can go higher and deeper in the space of the universe. Chinese astronauts refuel!
