And he inspires people to be involved and motivated to care about the environment as well.
The 50th anniversary of Starfish Prime: Designated Starfish Primeit was part of a dangerous series of high-altitude nuclear bomb tests at the height of the Cold War.
Its immediate effects were felt for thousands of kilometers, but it would also have a far-reaching aftermath that still touches us today. Inthe Soviet Union called for a ban on atmospheric tests of nuclear weaponsand went so far as to unilaterally stop such testing.
Under external political pressure, the US acquiesced. However, in late political pressures internal to the USSR forced Khrushchev to break the moratorium, and the Soviets began testing once again. So, again under pressure, the US responded with tests of their own.
It was a scary time to live in. The US, worried that a Soviet nuclear bomb detonated in space could damage or destroy US intercontinental missiles, set up a series of high-altitude weapons tests called Project Fishbowl itself part of the larger Operation Dominic to find out for themselves what happens when nuclear weapons are detonated in space.
High-altitude tests had been done before, but they were hastily set up and the results inconclusive. Fishbowl was created to take a more rigorous scientific approach. Goes the dynamite On July 9,the US launched a Thor missile from Johnston islandan atoll about kilometers miles southwest of Hawaii.
The missile arced up to a height of over km milesthen came back down. At the preprogrammed height of km milesjust seconds after And all hell broke loose.
However, nuclear weapons are fundamentally different from simple chemical explosives. TNT releases its energy in the form of heat and light.
Nukes also generate heat and light, plus vast amounts of X-rays and gamma rays — high-energy forms of light — as well as subatomic particles like electrons and heavy ions. When Starfish prime exploded, the effects were devastating. As you can see, the explosion was roughly spherical; the shock wave expanding in all directions roughly equally since there is essentially no atmosphere at that height.
Electrons are lightweight and travel rapidly away from the explosion. Those atoms and molecules absorbed the energy of the electrons and responded by glowingcreating an artificial aurora. Heavy ions atoms stripped of electrons are also created in the blast, and get absorbed somewhat higher up in the atmosphere.
The image here shows this glow as seen by an airplane moments after the nuclear explosion. The feathery filament is from the bomb debris, while the red glow may be due to glowing oxygen atoms; this tends to be from atoms higher than km, so the glow is probably due to the heavy ions impacting our air.
Taking the pulse of a nuclear weapon But the effects were far more than a simple light show. When the bomb detonated, those electrons underwent incredible acceleration.
When that happens they create a brief but extremely powerful magnetic field. This is called an electromagnetic pulse, or EMP. The strength of the pulse was so huge that it affected the flow of electricity on the Earth hundreds of kilometers away!
In Hawaii it blew out hundreds of streetlights, and caused widespread telephone outages. Other effects included electrical surges on airplanes and radio blackouts. When a high-speed electron hits a satellite, it can generate a sort-of miniature EMP.
The details are complex, but the net effect is that these electrons can zap satellites and damage their electronics. The pulse of electrons from the Starfish Prime detonation damaged at least six satellites including one Soviet birdall of which eventually failed due to the blast.We would like to show you a description here but the site won’t allow us.
