Neil Armstrong wore this spacesuit when he made his historic “one small step” onto the surface of the Moon on July 20, 1969. Before and after his two-and-a-half-hour lunar walk, he wore it inside the lunar module, but without the special gold visor helmet and with different gloves.
Armstrong’s spacesuit is basically a form-fitting spacecraft. It provided air to breathe; protected him from temperature extremes, radiation, and high-speed meteoritic particles; and allowed him to communicate with others.
