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 110 centimetres (42 in) in diameter by 22 inches (56 cm) in height, with a mass of 130 kilograms (290 lb). It was made of aluminum alloy and stainless steel covered with 10,020 solar cells. The cells charged 63 nickel–cadmium batteries, which served as a power source. The satellite could take 8 to 10 pictures every 24 hours. Each photo covered a 5,200-square-kilometre (2,000 sq mi) area at a resolution of 3.2 kilometres (2 mi) per pixel.

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.
