The next generation of aerospace uniforms is called "Exploration Extravehicular Mobility Unit (exploratory Mobile Force outside the vehicle", abbreviated as xEMU,Will be used in NASA's future Artemis mission.
Safety is the most important function of xemu. NASA learned from the Apollo mission that the soil environment of the moon surface is the biggest danger. The small pieces of glass in the moon surface will cause danger to the astronauts. Therefore, xemu is equipped with a set of dust-proof functions, which can prevent the inhalation of dust from the life support system or other spacecraft that can pollute the clothes.
The portable life support system of xEMU has also been improved, and the miniaturized electronic system in the spacesuit has further upgraded the stability of the spacesuit and increased the time for spacewalk.
XEMU also has more maneuverability and a redesigned communications system, thanks to embedded microphone systems, after astronauts'"Snoobi hats" will be completely a thing of the past, although space diapers are not retired, making it easier for astronauts to carry out long-term missions.
The xemu also supports modular designs, such as a quick replacement of the protective mask on the helmet, rather than the entire helmet, and a rich extensibility that allows a suit to adapt to both the moon and mars.
