Humans have always dreamt of going into space, and in 1959, NASA selected seven astronauts to do just that. Known as the Mercury Seven, this group of friends was America's first astronauts; in 1962, a member of this elite team became the first American to orbit the Earth. His name was John Glenn, and his spacecraft was named, fittingly, Friendship 7.
This model features aluminum, which has long held a central role in human exploration of the cosmos. The Soviets used it to build Sputnik, and the Americans used it to build the tiny lunar module Eagle (which ferried the Apollo astronauts to the moon). But it was the Mercury Seven astronauts who used it to make a fashion statement: their iconic, reflective spacesuits were made from aluminum-coated nylon.
