We all know about many uses of gold, it’s in jewellery, electronics etc. But do you know Gold is used to make astronaut’s helmets.

Gold comes full circle from being something from outer space to discovery application in space exploration.

This also helps keep the inside of the astronaut’s helmet cool.
