NASA dumped trimethyl aluminium (TMA) and a barium/strontium mixture into the magnetosphere Friday (don’t worry it’s perfectly safe!)
According to NASA, which funded the mission, on Friday night two rockets dumped trimethyl aluminium (TMA) and a barium/strontium mixture into the magnetosphere above Norway.
NASA claimed, "the chemicals pose no hazard to residents in the region."
But what was the purpose of the experiment?
According to NASA, the experiment was to measure winds and currents in the ionosphere, an electrically charged layer of the Earth’s atmosphere where auroras appear. Specifically, the researchers are interested in discovering how auroral energy might percolate down toward Earth to influence the lower atmosphere.
Or was the experiment something a little more sinister? Perhaps the most exotic form of geophysical warfare concerns tampering with the electrical behaviour of the ionosphere. Techniques for disturbing radio communication by “punching holes” in the ionosphere with nuclear explosions have been long discussed. So, too, have proposals for opening up lethal windows in the ionosphere to let in the short wavelength ultraviolet radiation which is known to damage biological systems, causing skin cancers in man and damage to crops. What is new, is the suggestion that the natural waveguide between the ionosphere and the Earth could be used to propagate very low frequency (VLF) radiation through it in such a way as to affect the electrical behaviour of individuals’ own brain activity.
