In this classic 1972 photograph, two unidentified NASA employees in period dresses pose in a sound-absorbing chamber next to the International Telecommunications Satellite. According to the NASA release, the Intelsat IV “was built by the Hughes Aircraft Company for an international consortium of 65 nations to meet the growing demand for channels of communication and greatly expanded the commercial communications network. Intelsat IV was placed in a synchronous orbit over the Atlantic Ocean with the capacity of about 6,000 circuits or 13 television channels.”
