This was the first nuclear explosion in history, 74 years ago and one day

If yesterday, July 16, fifty years of the Apollo 11 takeoff for the Moon, 74 years after the explosion of the first nuclear bomb in history, a few weeks before bombs were dropped on Hiroshima and Nagasaki.

The call Trinity test It took place in a remote enclave of the New Mexico desert. In the following video you can see the test.

In the test, they erected a wooden platform about 730 m from the zero zone and they piled up 100 tons of TNT by adding traces of nuclear fission products in the form of irradiated uranium from Hanford, which had been dissolved and poured into the explosive.

The device exploded with an energy equivalent to 19 kilotons, equivalent to 19,000 tons of TNT. He left a crater in the desert soil 3 meters deep and 330 meters wide. The shock wave could be felt 160 kilometers away. The mushroom cloud reached 12 kilometers.

In the crater, the desert sand, composed mainly of silica, melted into a light green glass, which was called trinitite.

The discovery of nuclear fission by German chemists Otto Hahn Y Fritz Strassmann In 1938, along with his theoretical explanation by Lise Meitner and Otto Robert Frisch, made the development of an atomic bomb a theoretical possibility.

Around 260 people witnessed the test, none at a distance of less than 9 kilometers. Robert Oppenheimer, one of the people often named "father of the atomic bomb" due to his outstanding participation in the Manhattan Project, the project that managed to develop the first nuclear weapons in history, was observing the test. He would later comment that the event reminded him of a line of the famous Indian text Bhagavad Gita: "I have become death, a destroyer of worlds."

The area was declared a National Historic Landmark in 1975 and is accessible to the public during the first Saturday of April and October.
