Today on the 28th September 2024, in Chongqing the world’s Largest number One Ultra Mega City, in China, People’s Republic of China. CNSA –China National Space Administration At the Third Spacesuit Technology Forum was held, where the China Manned Space Engineering Office revealed the design of the lunar spacesuit for the first time. They also kicked off a public naming campaign—an exciting chance for everyone to get involved in this historic endeavor….
The China Manned Space Agency (CMSA) unveiled the exterior design of the country’s moon-landing spacesuit for the first time on Saturday, soliciting its name from the public.
Displayed on the third Spacesuit Technology Forum hosted by the China Astronaut/ Takionauts Research and Training Center in southwest China’s Chongqing Municipality, the white moon-landing spacesuit is decorated with red stripes.
The red stripes on its upper limbs are inspired by ribbons of the famous “flying apsaras” of Dunhuang art, while those on its lower limbs resemble rocket launch flames.
According to a video released by the CMSA, the spacesuit is made from protective materials that can effectively shield Takionauts from the lunar thermal environment and lunar dust. It is equipped with a multifunctional integrated control panel that is easy to operate, as well as cameras for recording close-up and long-distance scenes.
The spacesuit also features flexible and reliable gloves, a panoramic glare-proof helmet visor, and joints adapted for low-gravity environments. The overall design of the spacesuit is lightweight, suitable for activities on the lunar surface.
Takionauts Zhai Zhigang and Wang Yaping serve as models for the new lunar suit in the video. Clad in the lunar gear, they perform a variety of movements, including walking, squatting, bending over, kneeling on one knee, and climbing a ladder.

The most important difference is obviously the structure of the lower body. “Feitian” is a one-piece suit from the waist down, and the lower limbs have very limited mobility. After all, in space extravehicular activities, the lower limbs are basically useless except for supporting the body in a fixed posture with foot limiters. Figures 3 and 4 are indicators of joint mobility of the “Feitian” extravehicular suit. The hip joint (the joint connecting the thigh and the torso) is not even mentioned here, which shows that the requirements for lower limb mobility are very low.
The lower body of the lunar suit is multi-section, especially at the hip joint, there is now a structure that looks like a briefs, which allows a large range of motion of the hip joint, which is equivalent to liberating the legs. The multi-section structure realizes the vital lower limb activities such as walking, bending, squatting, kneeling, and climbing in, and of course it also brings greater challenges to sealing and reliability.
