The three astronauts on the Chinese space station are about to end their stay period of up to 6 months, and in another week, they will return to the ground on the Shenzhou 13 spacecraft, and Shenzhou 13 will use rapid return technology for the first time, greatly shortening the return time, and it only takes more than 6 hours to return to the ground safely.
Now, we just have to wait patiently for a week to see the smiles of Zhai Zhigang, Wang Yaping and Ye Guangfu on the ground lens again, not from the camera lens of the space station, they are China's space heroes, well-deserved.
The last week, and their busiest time, was to increase physical exercise on the muscles of the whole body, especially the leg muscles, to normally carry out and maintain more than 20 space science experiments, and to make a big tidy up of the space station, carry out personal belongings when returning, and remove work garbage and household garbage.
At 3:00 a.m. Beijing time on April 10, that is, at 15:00 Eastern Time on April 9, the three Shenzhou 13 astronauts on the Chinese space station also did a big thing before returning, making video calls with a number of American children and answering the questions of American children.
Since the Chinese astronauts stepped into the Chinese space station, the astronauts have had a "heaven and earth interaction" with the cute children, especially the Shenzhou 13 astronauts, who patiently asked and answered the children's various whimsical questions when the "Tiangong Classroom" began.
"How do oxygen and carbon dioxide circulate on the space station?" "Will there be aliens in space?", "What's going to be delicious in the space station?" "Will astronauts float up when they walk?" "What is Aunt Wang Yaping's favorite song?" And so on.
At 15:00 Eastern Time on April 9, the three Shenzhou 13 astronauts on the Chinese space station had a "space interaction" with hundreds of American children and answered more than a dozen questions, which was the first interaction between Chinese space station astronauts and American children, which belonged to a "people-to-people exchange" between China and the United States.
"If you could bring something from space to your family, what would you bring?" "I grew up wanting to be an astronaut like you, what should I do now?" Wait, the Shenzhou 13 astronauts have answered these questions one by one.
This is the first "space interaction" between the Shenzhou 13 astronauts and american children, and it must have won a large number of small American fans, so that American children can understand what the interior of the Chinese space station looks like, compared with the dilapidated International Space Station, how advanced is the Chinese space station, so this is a historic moment.
In 2022, the Chinese space station will usher in the "most brilliant moment" in the history of spaceflight, in the next 8 months, there will be 6 spacecraft flying to the space station, and the Chinese space station will have a space event of "6 astronauts in orbit at the same time", which is another technical verification of the life support system of the intermediate space station.
The Chinese space station belongs to both China and the world, the Chinese space station has been opened to the world, 17 countries have joined the Chinese space station project, a number of foreign astronauts are trying to learn Chinese, hoping to enter the Chinese space station a day earlier, the Chinese space station is about to become the second "international space station".
It is worth mentioning that Russia is also a partner in China's space station project, Russia has world-class space station technology, has a wealth of experience in space station construction, from the Salyut space station to the peace space station in the last century, from the peace space station to the current International Space Station, there is the participation of the Russian Space Agency.
With the deepening of Sino-Russian relations, China is very welcome to Russia to join the Chinese space station project, recently, the Russian space agency Rogozin said: Russia will build a new module docking with the Chinese module, which means that the construction scale of the Chinese space station will be further expanded.
Chinese space station is also known as Tiangong space station, according to the construction plan of Tiangong space station, Tiangong space station will be composed of Tianhe core module, Qingtian experimental module and Dream Experiment module, in the case of stationed people, at least one Tianzhou cargo spacecraft and a Shenzhou manned spacecraft docked on the space station dock, that is, "three cabins and two ships".
In the future, the module built by Russia is docked with the mainland Tiangong space station, and with the Addition of Russian spacecraft, the Tiangong Space Station will form a "four-cabin and three-ship" structure, although the scale cannot be compared with the International Space Station with 16 modules and modules, but although the sparrow is small, it is complete.
The Shenzhou 13 spacecraft is about to return, which means that Tianzhou 4 and Shenzhou 14 have also entered a state of "ready to go", and who are the Shenzhou 14 astronauts? In fact, it has long been determined that it will not be made public until the last minute, and it is estimated that the list of Shenzhou 14 astronauts will be revealed in May.
