In general, nuclear effects in space (or very high altitudes) have a qualitatively different display. While an atmospheric nuclear explosion has a characteristic mushroom-shaped cloud, high-altitude and space explosions tend to manifest a spherical 'cloud' until distorted by Earth's magnetic field.
The flash created by the explosion as seen through heavy cloud cover from Honolulu, 900 miles (1,450 km) away. Starfish Prime was a high-altitude nuclear test conducted by the United States, a joint effort of the Atomic Energy Commission (AEC) and the Defense Atomic Support Agency.
In July 1962, the US carried out the Starfish Prime test, exploding a 1.44 Mt (6.0 PJ) bomb 400 kilometres (250 mi; 1,300,000 ft) above the mid-Pacific Ocean.This demonstrated that the effects of a high-altitude nuclear explosion were much larger than had been previously calculated.

The high-altitude nuclear tests delivered the first openly reported man-made high-altitude electromagnetic pulses (EMP). Teak, which was detonated at 252,000 feet (76.8 km) and was 3.8 megatons of TNT (16 PJ), produced an aurora-like effect that was visible from Hawaii, 700 nautical miles (810 mi; 1,300 km) displaced from the detonation. Most ...
The United States completed six high-altitude nuclear tests in 1958, but the high-altitude tests of that year raised a number of questions. According to U.S. Government Report ADA955694 on the first successful test of the Fishbowl series, "Previous high-altitude nuclear tests: Teak, Orange, and Yucca, plus the three ARGUS shots were poorly instrumented and hastily executed.
RELATED: Here is the aftermath of the atomic bomb dropped on Hiroshima. The very first time the U.S. built a nuclear weapon was in December 1941, and the first regular nuclear test took place on ...
Operation Dominic was a series of 31 nuclear test explosions ("shots") with a 38.1 Mt (159 PJ) total yield conducted in 1962 by the United States in the Pacific. [1] This test series was scheduled quickly, in order to respond in kind to the Soviet resumption of testing after the tacit 1958–1961 test moratorium.
