アメリカ合衆国が高高度核爆発実験「スターフィッシュ・プライム」を実施。
The United States conducted the high-altitude nuclear test "Starfish Prime", detonating a 1.4 megaton bomb above the Pacific Ocean.
On July 9, 1962, the U.S. carried out Starfish Prime, a high-altitude nuclear test in the Pacific Ocean over Johnston Island.
The 1.4 megaton detonation at an altitude of 400 kilometers produced intense electromagnetic pulses (EMP).
The blast created artificial auroras visible hundreds of kilometers away, illuminating the night sky.
EMP effects damaged electrical systems in Hawaii, demonstrating the dangers of high-altitude nuclear bursts.
Starfish Prime shaped future policies on nuclear testing and contributed to the 1963 Partial Test Ban Treaty.
