First Atomic Bomb; Trinity Test 1945 & Today
Update: 2021-07-16
Description
On July 16, 1945, a predawn thunderstorm moved through the desert near Alamogordo, New Mexico, about 120 miles south of Albuquerque. After it passed, at 5:29:45 a.m., detonators ignited explosives around a large, steel, globe-shaped device on a 100-foot tower. The explosion prompted a fission chain reaction in the plutonium inside the globe. The resulting nuclear blast from the Gadget, as the device was called, released an explosive force of 21 kilotons (equivalent to 21 thousand tons of TNT). It created a blinding flash of light, a thunderous sound, and a mushroom cloud 38,000 feet tall. “Some people claim to have wondered at the time about the future of mankind,” remembered physicist Norris Bradbury of witnessing the event. “I didn’t. We were at war, and the damned thing worked.” This was the Trinity test, the culmination of 27 months of work at Project Y—a secret laboratory in Los Alamos—to create the world’s first atomic bomb.
In this episode of the National Security Science podcast, on the 76th anniversary of the Trinity test, we examine the test from two angles: from 1945, when the test occurred, and from 2021, when a group of Los Alamos employees traveled to the Trinity site to tour ground zero and the surrounding area.
