Chinese extravehicular spacesuit

The extravehicular spacesuit is a miniature spacecraft that not only has all the functions of an in cabin spacesuit, but also adds functions such as radiation protection, insulation, micrometeorite protection, and UV protection. A liquid cooling system (liquid cooling suit) is added to the clothing. The second-generation "Feitian" extravehicular suit developed by China weighs about 130 kilograms and costs about 30 million yuan. The second generation product adopts a semi-rigid structure, with a single discharge capacity of more than 8 hours, and an extended service life of "4 years and 20 times". The joints are more flexible through airtight bearings. The helmet is equipped with a gold-plated filter window, and the life support system is integrated into the back "backpack", which can support multiple generations of astronauts' extravehicular operations. This model 1:1 reproduces the appearance characteristics of the second-generation "Feitian" extravehicular service. 01 Reflective mirror is used to expand the field of view of astronauts, allowing them to view the mirror markings on their spacesuits through mirror reflection, thereby obtaining forward readable operational information. 02 Reflection effect on the outer layer of the window.

The unit is designed for unsupervised public use: controls are recessed or shielded, moving parts are enclosed, and the interface is operable by a child of about six with no instruction. Where a screen is used, the language can be switched without changing the hardware, and the content can be replaced on site.
