The National Security Science podcast is a spin-off of National Security Science magazine at Los Alamos National Laboratory. We bring you stories from the Lab’s Weapons programs—stories that show how innovative science and engineering are the key to keeping America safe. Or, as we like to say, better science equals better security.

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.
