(1945) Nuclear age begins in New MexicoArchitects of the Manhattan Project, including project director J. Robert Oppenheimer, gather in shelters 10,000 yards from ‘The Gadget’s’ detonation site in New Mexico and at 5:29 AM the world’s first nuclear bomb explosion, code-named Trinity, pierces the darkness with 20 kilotons of atomic power.Trinity was the code name of the first detonation of a nuclear weapon. It was conducted by the United States Army at 5:29 am on July 16, 1945, as part of the Manhattan Project. The test was conducted in the Jornada del Muerto desert about 35 miles southeast of Socorro, New Mexico, on what was then the USAAF Alamogordo Bombing and Gunnery Range. The only structures originally in the vicinity were the McDonald Ranch House and its ancillary buildings, which scientists used as a laboratory for testing bomb components. A base camp was constructed, and there were 425 people present on the weekend of the test.
