In 1963, it was reported that Starfish Prime had created a belt of MeV electrons. [17] In 1968, it was reported that some Starfish electrons had remained in the atmosphere for 5 years. [18] A year later, the US and USSR signed the Partial Nuclear Test Ban Treaty, which banned all above-ground nuclear testing. France and China continued above ...
The Starfish Prime radiation belt had, by far, the greatest intensity and duration of any of the artificial radiation belts. [1] The Starfish Prime radiation belt damaged the United Kingdom Satellite Ariel 1 and the United States satellites, Traac, Transit 4B, Injun I and Telstar I. It also damaged the Soviet satellite Cosmos V. All of these ...
Hardtack Teak, 1958 Frame of the Starfish Prime nuclear test. High-altitude nuclear explosions are the result of nuclear weapons testing within the upper layers of the Earth's atmosphere and in outer space. Several such tests were performed at high altitudes by the United States and the Soviet Union between 1958 and 1962.
On 9 July 1962, decay of debris the Starfish Prime nuclear test utccreated an unexpected increase in high-energy particles in the Earth's magnetic field. Scientists were not sure how long the radiation and its effects would last. The Air Force Cambridge Research Laboratory was asked to design and build STARAD to study the radiation. [2]
The Starfish Prime electromagnetic pulse also made those effects known to the public by causing electrical damage in Hawaii, about 1,445 kilometres (900 mi) away from the detonation point, knocking out about 300 streetlights, setting off numerous burglar alarms and damaging a telephone company microwave link [10] (the detonation time was nine ...
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 109 kg satellite was used to test the feasibility of using gravity-gradient stabilization in Transit navigational satellites. [2] It provided information on the effects of radiation from nuclear explosions in space, as it was one of several satellites whose detectors provided data for the Starfish Prime test; ultimately its solar cells were damaged by the radiation and it ceased operation. [3]
Ariel 1 was among several satellites inadvertently damaged or destroyed by the Starfish Prime high-altitude nuclear test on July 9, 1962, and subsequent radiation belt. Its solar panels sustained damage from the irradiation, affecting Ariel 1's operations. [13] The satellite operated even after the nuclear test.
