Gold layer in astronauts' helmets

The gold visor on astronauts' helmets is used to protect the eyes from the intense sunlight in space, where there is no atmosphere to filter the rays as on Earth. The thin gold coating reflects some of the harmful rays while allowing visible light to pass through, enabling clear vision during space missions. This design has been used since the Gemini 4 mission in 1965 and was employed during Apollo missions, including the moon landing, to safeguard the eyes from harmful radiation and heat. Gold is resistant to corrosion, and its conductive properties are beneficial in satellite components.
