On July 9, 1962, the largest in a series of tests involving nuclear explosions in space was conducted by the United States. Dubbed Starfish Prime, the test involved the launch of a W49 thermonuclear warhead developed at Los Alamos from Johnston Atoll in the Pacific Ocean.
The warhead detonated approximately 250 miles above the Earth, producing belts of radiation as high-energy electrons became trapped, amplifying the magnitude of the natural Van Allen radiation belt and increasing the potential adverse effects of the trapped radiation.
Now, a scientist at Los Alamos National Laboratory has found a novel means of offering better protection for space technologies: by fixing mistakes in mathematical calculations related to the effects of nuclear explosions in space that have gone undetected for close to half a century.
The errors relate to our understanding of the influence electromagnetic waves exert on the dispersal of electrons that become trapped in the planet’s magnetic fields when nuclear explosions in space occur.
According to Greg Cunningham, a space scientist with Los Alamos National Laboratory, the discovery and resolution of these longstanding errors in past mathematical calculations will offer scientists an opportunity to improve protections for space technologies, particularly involving models governing the effects of radiation resulting from the detonation of nuclear devices at high altitudes.
“This allows us to make better predictions of what that threat could be and the efficacy of radiation belt remediation strategies,” Cunningham said in a recent statement.
