In 1963, the United States military launched hundreds of millions of tiny copper needles into orbit around Earth in one of the strangest experiments of the Cold War, an attempt to build an artificial reflector for radio signals circling the planet. The story of the project was recounted by the outlet SpaceDaily.
The effort was known as Project West Ford, developed by specialists at MIT Lincoln Laboratory. Its goal was to test whether a cloud of metal dipoles could serve as a passive relay for long-distance radio communication. The payload carried roughly 480 million copper needles, each about 1.8 centimetres long, meant to act as tiny antennas that would scatter a signal sent from a ground station.
What was Project West Ford
The figure of 480 million needs some clarification. According to the report, that number referred to the total elements packed into the payload, not the number of needles that actually separated and began orbiting Earth individually. NASA estimated that around 120 to 215 million dipoles dispersed on their own, while a significant portion remained clustered together.
The authors of the report described it as a useful cloud, but not a solid sheet of metal. The report stressed that the sky above Earth was never covered by a continuous layer: millions of needles spread across an enormous area while remaining extremely sparse. The experiment was designed to determine whether enough dipoles would end up at any one time within the shared field of view of a transmitting and a receiving antenna.
A first attempt was made in 1961, but the dipoles failed to deploy properly. An improved launch in 1963 proved more successful, with a closed belt forming around Earth over about 40 days. A spring mechanism ejected a container of tightly packed needles, which then gradually separated and spread out to form the orbital cloud.
Mixed results in orbit
The system showed decent results at first. According to Lincoln Laboratory, when the dipoles were still relatively concentrated, the data transmission rate reached 20,000 bits per second. But as the metal cloud spread out, its effectiveness fell, since fewer and fewer needles ended up in the zone covered by both antennas at once.
The report's author noted that the spreading of the material formed a ring, but at the same time diluted the very material that made that ring useful. That contradiction became one of the central problems of Project West Ford: the dipoles needed to spread out to form a reflector, but excessive dispersal steadily weakened the radio channel.
The project also worried astronomers. The metal objects ended up in the same region of space used to observe extremely faint radio signals, meaning that success for the military communications experiment came with negative consequences for other kinds of research.
The fate of the needles varied. Some, because of their small size, lost orbit relatively quickly, partly due to the pressure of solar radiation. Larger clusters, however, stayed in space for much longer. NASA reported in 2013 that 46 clusters of the material were still catalogued.
In the end, the passive system never became the basis for global communications. Active satellites proved more practical, while West Ford required complex ground equipment and offered limited capabilities.
Other Cold War experiments
As UNIAN has previously reported, the United States drew up a secret plan in 1958 known as Project A119, which called for detonating a nuclear charge on the Moon to demonstrate American power to the Soviet Union. The idea was meant to produce a spectacular explosion visible from Earth, but it was abandoned over fears of radioactive contamination and the risk of international embarrassment if the launch failed.
UNIAN also reported that in 2024 researchers unexpectedly discovered the remains of Camp Century under the ice of Greenland, an American base built in 1959 as part of the secret Project Iceworm. Diesel fuel, wastewater and radioactive waste from the site remain there, still sealed beneath the thickness of the ice.
