To get distracted and give my brain a chance to switch on to something else, I renewed my memory of another project HARP, spelt with a single ‘A’. This story dates to 1961, long before the construction of the aerial fields of the current HAARP in Alaska.
Everything began, as it often does, with the scientists. They constructed an experimental light-gas cannon with a barrel thirty metres long in order to track the behaviour of ballistic objects. But soon the military became interested in the cannon, and HARP received financial support and began to develop rapidly. It was assumed that the cannons will throw out small military satellites to heights of up to two hundred kilometres, the so-called low orbits. It was much cheaper and quicker than taking the devices into space by rocket.
