Thanks to CTOnews.com netizen grass Luo Yuzi for the clue delivery! CTOnews.com, September 19, the Shenzhou 14 crew of China's space station has successfully completed two extravehicular missions. Some netizens noticed a detail. Liu Yang's extravehicular spacesuit also bears the names of Wang Yaping and Ye Guangfu, and the three astronauts wore the same suit one after another.

Recently, the China manned Space Engineering Office officially answered some questions about the extravehicular spacesuit, such as the service life and personnel adaptation of the extravehicular spacesuit.

First of all, the service life of the new generation of extravehicular spacesuit is 3 years and 15 times, and the working time for a single support is 8 hours. If it expires or reaches the usage limit, on-orbit maintenance will be attempted, and those that cannot be repaired will be discarded. The current plan is to replace them in two batches.

Secondly, due to the limited space in the space station, the development cost and transportation cost are extremely expensive, so the extravehicular spacesuit does not need to be tailored to each person. According to the configuration of Feitian extravehicular spacesuit, the suitability principle of "one to many" is adopted, that is, multiple people wear a suit of clothing, combining passive appropriateness with active appropriateness, and taking into account the requirements of individuality and generality.

At present, there are three sets of extravehicular spacesuits with red (A), blue (B) and yellow (C) ribbons inside the Chinese space station. In line with the principle of prolonging the service life in orbit, the frequency of three extravehicular spacesuits should be balanced as far as possible in the selection of each extravehicular mission.

Finally, with regard to the future extravehicular spacesuit, the China manned Space Engineering Office said that China's design idea is modular, lightweight, multi-purpose integrated design.

CTOnews.com learned that at 00:33 on September 2, 2022, Beijing time, after about six hours of extravehicular activities, Shenzhou 14 astronauts Chen Dong, Liu Yang, and Cai Xuzhe closely coordinated to complete all the tasks set during the extravehicular activity. Chen Dong and Liu Yang have safely returned to the sky-asking experimental module, and the first extravehicular activity has been a complete success.

17:47 on September 17, Beijing time, after about five hours of extravehicular activities, Shenzhou 14 astronauts Chen Dong, Liu Yang, and Cai Xuzhe closely coordinated to complete all the scheduled tasks during the extravehicular activities. Astronauts Chen Dong and Cai Xuzhe have safely returned to the sky-asking experimental module, and the second extravehicular activity has been a complete success.
