"ESSA-8 was a weather satellite launched by NASA on December 15, 1968. It operated for 2,644 days until it was deactivated on March 12, 1976. ESSA-8 was launched from Vandenberg Air Force Base, CA. ESSA-8 was an 18-sided polygon. It measured centimetres ( in) in diameter by inch (cm) in height, with a mass of kilograms ( lb). It was made of aluminum alloy and stainless steel covered with 10,020 solar cells. The cells charged 63 nickel\u2013cadmium batteries, which served as a power source. The satellite could take 8 to 10 pictures every 24 hours. Each photo covered a -square-kilometre (sq mi) area at a resolution of kilometres ( mi) per pixel."@en . . . "--12-15"^^ . . . . .

ESSA-8's mission was to replace ESSA-6, and provide detailed cloud pattern photography to ground stations worldwide. Partners in the project included NASA, ESSA, RCA, the U.S. Weather Bureau, and the NMC."@en . . . "1968"^^ . . "ESSA-8"@en . "gee"@en . . . . "6877.799999999999"^^ . . "--12-07"^^ .
