Project West Ford

Project West Ford

Project West Ford (also known as Westford Needles and Project Needles) was a test carried out by Massachusetts Institute of Technology's Lincoln Laboratory on behalf of the United States Military in 1961 and 1963 to create an artificial ionosphere above the Earth. This was done to solve a major weakness that had been identified in US military communications.

At the height of the Cold War, all international communications were either sent through undersea cables or bounced off of the natural ionosphere. The United States Military was concerned that the Soviets might cut those cables, forcing the unpredictable ionosphere to be the only means of communication with overseas forces. So, a ring of 3.5e|8 copper dipole antennas (1.78cm long and 25.4μm (1961) and 17.8μm (1963) diameter needles)citation

] was placed in orbit to allow global radio communication. The dipoles collectively provided passive support to Project West Ford's parabolic dish (located in the town of Westford) to communicate with distant sites.

After a failed first attempt launched on October 21, 1961 (the needles failed to disperse), the project was eventually successful with the May 9, 1963 launch, with radio transmissions carried by the man-made ring. However, the technology was ultimately shelved, partially due to the development of the modern communications satellite and partially due to protests from other scientists.cite web

] Stevenson studied the published journal articles on Project West Ford. Using what he learned on the subject and citing the articles he had read, he successfully allayed the fears exhibited by the vast majority of UN ambassadors from other countries. He and the articles explained that sunlight pressure would cause the dipoles to only remain in orbit for a short period of approximately three years. The international protest ultimately resulted in a consultation provision included in the 1967 Outer Space Treaty. Contrary to the project's supporter's claims, as of 2008, several clumps of the needles are still in orbit,citation
