The National Museum of Nuclear Science and History in Albuquerque traces the scientific, historical, and cultural story of the Atomic Age. Founded in 1969 on Sandia Base as the Sandia Atomic Museum, it evolved from a base-focused interpretation of nuclear weapons development into a nationally chartered institution with a broader mission covering nuclear history and science. After moves prompted first by growth and later by post-September 2001 security limits, it opened at its present site in 2009. Its exhibits span the atom’s early study, World War II, Los Alamos, the Cold War, nuclear medicine, energy, radiation, and atomic culture, with major artifacts and educational programs reflecting New Mexico’s central role in the nuclear age.
