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."

      Close. If we were to launch ALL of the copper found on the earth, every last scrap of it, we could do what they wanted, problem is there would be no copper left to make radios to transmit or receive with. This was the problem, Yes it "worked" but the scale needed would have required global strip mining and launching every ounce of copper that this planet has in it's crust.

      Citation needed. From what I read it seams they did a succussfull test that formed a belt. I think your thinking of an actual unbroken wire going around the earth. Instead they launched short segments of wire. There was some distance between each bit.

      Early in May, 1963 a package containing 4.8×108copper dipoles, each 0.00178 cm in diameter and 1.78 cm in length, was placed into a nearly circular, nearly polar orbit at a mean altitude of 3650 km

      also back then LEO was about as distant and exotic as Andromeda galaxy, lotsa room for all kinds of stuff i.e. spent boosters, loose nuts, flaked debris (space FOD). Who cares? this was also in days of "gas washdowns" where fire departments respond to traffic collisions to use fire hoses to wash gasoline off the pavement into gutters or side of road (gasoline makes asphalt soft leading to potholes). Totally illegal these days but back then there was lots of room for pollutants. But "earthrise" picture from Apollo 8 changed all when we saw our only habitat is this small speck in vastness of space (terraforming Mars don't count).

      So they had a good idea of the dispersion of space junk in the early 1960s? And yes, the equations were well known, but had they been tested at long range with scattered dipoles?

      The practical realities of the time are they needed to test rockets. They were going to launch a dummy load of some kind for tests. So why not launch something that also tested another cold-war defense theory? It added little to the cost of the launch, other than some small bits of copper. So why the vitriol?

      They wasted $10 on copper in a larger moon landing project. The only rational reading of your post is that you think all governmental space launches are a waste of money, and we should never have gone to the moon or built a shuttle.

    There was quite a lot of bizarre technology pursued/developed in the cold war for communications, among other things. A similar system was meteor burst communications. The idea was you'd bounce your radio signal off the ionization trail of a meteor for the brief time it existed then wait for the next and so on. This way you could communicate way beyond the normal horizon without satellites, ground repeaters, etc. Unlike many crazy Cold War ideas, it was successful and is still used for military, civilian and amateur purposes.

    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.

An interesting side effect is the transmission takes over 5 seconds to reach the moon and return. thus the operator can hear the last 5 seconds of their own transmission.
