What Does EVVA Stand For?

EVVA stands for Extravehicular Visor Assembly

EVVA, or Extravehicular Visor Assembly, refers to a specialized component used in spacesuits designed for extravehicular activities (EVAs). It functions as a protective visor that shields astronauts from harmful solar radiation, micro-meteoroids, and extreme temperature fluctuations while providing clear visibility in the harsh conditions of space. The assembly typically includes advanced materials and coatings to enhance durability and optical clarity, ensuring the safety and effectiveness of astronauts during their missions outside spacecraft.
