China News Agency, Beijing, August 5 (Mar Shuaisha Guo Chaokai) The Shenzhou 12 astronauts have been flying in orbit for 7 weeks. What are the astronauts doing on the Chinese space station recently?
How to spend leisure time?
How to maintain good health?
The new "spoiler" of astronauts' space life has once again attracted attention. Many people said that "Astronauts who are busy watching the Olympics should not forget the astronauts "out of the sky".
The reporter was informed that more than half of the flight time in orbit, the three astronauts have carried out a series of scientific experiments using the human system research cabinet, which covers research from bone, cardiovascular, muscle and other human systems to cytological mechanisms.
It is reported that the China Space Station will implement 49 aerospace medical experiment projects, and the Shenzhou 12 mission will complete 14 projects.
Li Yinghui, a researcher at the China Astronaut Research and Training Center and deputy chief designer of astronaut systems, said that these 14 projects are aimed at three directions. New exploration, the third is to accumulate long-term flight data.
While carrying out space work in an orderly manner, astronauts also need to carry out routine medical examinations by themselves.
Astronauts have lived in space for more than a month and may show some symptoms of space disease.
In order to ensure that astronauts can spend the three months of space life safely and smoothly, Xu Chong, director of the Medical Supervision and Insurance Office of the China Astronaut Research and Training Center, said that a medical inquiry call must be completed every day between the world and the earth, and a health assessment must be conducted every week. A comprehensive assessment is required every month.
What is the experience of doing a "physical examination" in space?
In several videos released recently, astronaut Tang Hongbo not only performed venous blood sampling for Nie Haisheng, but also performed fundus examinations for his teammates in a dark room environment.
It is understood that fundus examination is an important item for astronauts’ medical supervision and insurance work. Many systemic diseases, such as hypertension, kidney disease, diabetes, and certain blood diseases, often have fundus diseases.
In an interview with the media, Xu Chong revealed that the astronauts must check each other, perform venous blood sampling, routine blood tests, and routine urine monitoring. At the same time, they must learn ultrasound examinations, such as cardiac ultrasound, abdominal ultrasound, lower limb muscle ultrasound, and ultrasound. Image evaluation and routine medical examinations are "a piece of cake" for them.
"Bone loss" is also one of the spatial pathological phenomena.
As astronauts live in a weightless environment for a long time, their bone density will gradually decrease; in order to combat the physiological effects of weightlessness, they have to take physical exercises every day.
Space treadmills, space bicycles, tension belts...With these equipment, astronauts can also perform "fancy fitness" on the space station.
The gravity simulation device on the space treadmill allows astronauts to run in a normal gravity environment.
Prior to this, Tang Hongbo also used a camera to take pictures of the "fitness expert" Nie Haisheng while running.
It is understood that astronauts flying for a long time generally spend no less than 2 hours a day in motion.
Li Yinghui said that exercise is now commonplace for astronauts. The longer the flight time, the greater the intensity of exercise. Only in this way can the physiological effects of weightlessness be countered.
In addition to work and fitness, in their spare time, astronauts also pay attention to ground information.
It is understood that the ground will send them news programs at regular intervals, and there are pictures of astronauts gathering together to watch the news simulcast in the public video.
In addition, the three astronauts are equipped with smart phones and tablet computers, and can make calls and make online videos normally. In addition to communicating with ground crews, they can greet each other with their families in their spare time.
Astronauts can also control the lights in the space station through the application software on these smart devices, and obtain information about the items in the package and the experimental equipment by scanning the QR code.
Wired intercom and Bluetooth bone conduction headsets allow astronauts not only to communicate more efficiently and lightly when making calls and videos, but also to occasionally listen to music.
