Starfish Prime

 

Safe and Away

Safe and away.

Twice in one day I have heard references to Starfish Prime. First in my plasma physics course and second in a paper on electromagnetic resonances in the earth-ionosphere cavity.

So I looked it up.

Starfish Prime was one in a series of high altitude nuclear tests. This particular one was detonated over 400km, well into the ionosphere. The EM pulse wiped out many low earth satellites, it destroyed electronics in nearby Hawaii¬†and lunched a bunch of radioactive particles into space along the earth’s magnetic field lines.

The one good thing it did was introduce a lot of radioactive tracers into the inner radiate belt, thus allowing for the lifetime of particles in the belt to be measured.

Otherwise the thought of high altitude nuclear tests is a bit worrisome.
