Cold War Plan Tried To Put a Copper Ring Around the Earth

Wired has the story of a plan enacted in the early 1960s by the U.S. Air Force and the Department of Defense that had the goal of safeguarding the country's long-range communications from Russian interference. The solution they came up with wasn't easy, but it was straightforward: launch hundreds of millions of thin copper wires into orbit in the hopes of forming an artificial ring around the planet. From the article: "Project Needles, as it was originally known, was Walter E. Morrow’s idea. He suggested that if Earth possessed a permanent radio reflector in the form of an orbiting ring of copper threads, America’s long-range communications would be immune from solar disturbances and out of reach of nefarious Soviet plots. Each copper wire was about 1.8 centimeters in length. This was half the wavelength of the 8 GHz transmission signal beamed from Earth, effectively turning each filament into what is known as a dipole antenna. The antennas would boost long-range radio broadcasts without depending on the fickle ionosphere. ... On May 9, 1963, a second West Ford launch successfully dispersed its spindly cargo approximately 3,500 kilometers above the Earth, along an orbit that crossed the North and South Pole. Voice transmissions were successfully relayed between California and Massachusetts, and the technical aspects of the experiment were declared a success. As the dipole needles continued to disperse, the transmissions fell off considerably, although the experiment proved the strategy could work in principle."

      It would also need to spin perpendicular to the magnetic field, so there is a change in polarity as it spins. You'd need to start spinning it some other way though, because the earth doesn't rotate north to south. The 23odd degrees offset of magnetic north probably would be enough to do anything.

    Think of the possibilities... Some have played with receiving TV signals from the other side of the planet via moon-bounce. A signal reflector so much closer would offer many more possibilities. It's an electromagnetic gateway to the other side of the planet. These days, it would probably get adapted to laser communications as well, while no current satellites have that option. Just as a test-bed for experiments like this which can't be performed economically any other way, it sounds like a great project to fund. Why haven't we even attempted any such thing, since active satellites became possible?

You send up a rocket into the stratosphere with a million shards of metallized fiberglas (which weighs a few pounds total) and disperse them over a wide area. They float down over several hours; meanwhile all the other guy's radar sees is a bright cloud where normally he'd see your invading bombers.

    The ARPANET was not started to create a Command and Control System that would survive a nuclear attack, as many now claim. To build such a system was, clearly, a major military need, but it was not ARPA's mission to do this; in fact, we would have been severely criticized had we tried. Rather, the ARPANET came out of our frustration that there were only a limited number of large, powerful research computers in the country, and that many research investigators, who should have access to them, were geographically separated from them.

    Of course the military wasn't to be left out of any hi-tech toys so they later created their own MILNET (in '83) that used the same ARPANET technology, but was totally under their control. In this case (as is often the case) the egg came first, then the chicken was adopted by the military.
