9 May[1] | Westford-2 | Communications experiment | 46[1] | As part of an experiment to facilitate international telecommunications, the US Military deployed an artificial space ring consisting of hundreds of millions of tiny copper needles[2] which would act as antennas reflecting radio signals at the target wavelength of 8 GHz. A large proportion of the needles were not dispersed properly and remained stuck in clumps that were discovered and tracked by the SSN between 1966 and 1991. As of October 2013[update], 46 of the 144 detected debris clumps remain in orbit.[1] The needles that were properly dispersed are believed to have decayed.[1]
This event prompted international protests[3][4][5][6] and influenced the drafting of the 1967 Outer Space Treaty.[3] |
