The world's first nuclear test, "Trinity", took place on 16 July 1945, in a torrid desert in New Mexico which the Spanish Conquistadores had named Jornada del Muerto (Journey of the Dead Man). In the decades that followed, over 2,000 such tests occurred in eight countries, some in the atmosphere, some underground and others underwater. Today, the world is poised to turn a new page in the history of nuclear testing.
