First, its most significant feature is improved mobility and greater flexibility. Astronauts experience less lower limb movement during spacewalks from the International Space Station, but more when walking on the lunar surface and conducting scientific activities. The new spacesuit's design fully considers this need, incorporating multiple joint bearings in the lower body of its pressure suit to allow for hip flexion and rotation, greater knee flexion, and a flexible sole similar to hiking boots.
China's space station extravehicular activity (EVA) suits have successfully supported 19 EVA missions; the first batch of EVA suits in orbit have demonstrated stable performance and extended service life.
Second, the new spacesuit significantly enhances safety and protection. Safety is always paramount in human space missions. This new EVA suit can protect astronauts from radiation, lunar dust, and micrometeoroids in temperatures ranging from approximately -157°C to approximately 121°C.
Third, the new spacesuit employs a modular design, facilitating component replacement during long-duration exploration missions. For example, its helmet features a quick-change visor. If surface damage, dents, or scratches occur, the visor can be replaced individually, eliminating the need to send the entire helmet back to Earth for repair.
The second-generation spacesuit offers significantly improved functionality and comfort compared to the first generation. Kudos to our country!
Fourth, the new spacesuit enhances comfort. At NASA's Johnson Space Center, researchers conducted full-body 3D scans of astronauts in motion and designed components based on 3D animation models, maximizing the comfort of the spacesuit and reducing potential skin discomfort.
