A History of Spacewalking

Extra-Vehicular Activity, or EVA, is the term for any activity done by an astronaut or cosmonaut outside a spacecraft, beyond the Earth's appreciable atmosphere. It's more commonly known as a "spacewalk." This simple term fails to capture the complexity, danger, and sheer audacity of the endeavor. An EVA is not a walk. It is a one-person ballet in a hostile void, a delicate and dangerous operation where the astronaut becomes a living spacecraft.
