Hero is back!Shenzhou Thirteen Astronauts Arrived in Beijing Safely on Space Business Trio’s Rehabilitation Project Exposure

Astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu, who successfully completed the Shenzhou 13 manned mission, arrived in Beijing safely on the mission plane. It is reported that the three astronauts will enter a medical isolation period after arriving in Beijing, conduct a comprehensive medical examination and health assessment, and arrange for rest and recuperation.

A six-month business trip in space, expedition to the stars and sea. On April 16, the Shenzhou 13 manned spacecraft return capsule successfully landed in the predetermined area of ​​the Dongfeng Landing Site, and astronauts Zhai Zhigang, Wang Yaping and Ye Guangfu exited the capsule safely and smoothly.

According to CCTV news reports, noodles, steamed buns, millet porridge, shredded potatoes in vinegar, cabbage in vinegar, mustard, Sichuan sausage, cucumber, tomatoes, watermelon… The first meal of the astronauts home is very rich and personalized. custom made!

In addition, the rehabilitation project of the space trip trio has also been exposed. There are as many as 18 categories, including Chinese herbal bath, acupuncture and massage. The three will first undergo a one-week tertiary isolation in the astronaut apartment, and then undergo six months of rehabilitation training. .

What effect will long-term space “business trips” have on astronauts’ bodies? Why do we see astronauts with physical fitness called “superhuman” being carried away after they exit the re-entry capsule? How long does it take to get used to life on the ground after a “space trip” back to Earth? With these questions in mind, researcher Jiang Zhenglin, former dean of the Institute of Special Medical Sciences of Nantong University, said that the precision of the human body is unimaginable, but as a creature on Earth, it will be difficult to adapt to life in space without a lot of training. “Long-term spaceflight will bring many physical and psychological problems to astronauts. The core reason is the weightless environment in space and the long-term separation from human society.”

“The impact of weightlessness on the human body is comprehensive and extensive.” Jiang Zhenglin introduced that in the case of weightlessness, the body’s body fluids will be rapidly transferred and redistributed. In particular, blood that accumulates in the lower extremities will metastasize to the head. Studies have shown that about 2L of body fluids are transferred from the lower half of the body to the upper half, and blood is also transferred to the head; as the hydrostatic pressure disappears, the body fluids are transferred from the inside to the outside of the capillaries. This is one of the reasons for the “puffiness” of astronauts.

“Therefore, the selection of special professionals, including astronauts and divers, not only requires high technical inspection requirements, but also undergoes strict physical and psychological tests. Before performing tasks, according to occupational characteristics, targeted measures will be conducted on the ground. training, such as physical exercise, weightlessness simulation training, overweight training, vestibular function exercise, pressurization exercise, mental health training and other adaptive training.” Jiang Zhenglin said.
