ESSA-9, also known as TOS-G, was a meteorological satellite. [4] Its name was derived from that of its oversight agency, the Environmental Science Services Administration (ESSA). ESSA-9 replaced the ESSA-7 satellite.

Aug 16, 2023 · ESSA-9. The ESSA-9 satellite replaced ESSA-7 and provided cloud-cover photography to the US's National Meteorological Center for the purpose of preparing operational weather analyses and forecasts. The spacecraft was an 18-sided polygon, 42 inches in diameter, 22 inches high and weighed 320 pounds.

3 days ago · ESSA 9 was a sun-synchronous meteorological satellite designed to take and record daytime earth cloudcover pictures on a global basis for subsequent playback to a ground acquisition facility. The spacecraft was also capable of providing worldwide measurements of reflected solar and long-range radiation leaving the earth.

The television camera and infrared sensors onboard the ESSA-9 satellite scanned the Earth once a day in a north-south polar orbit, producing images such as this one taken on the first Earth Day, April 22, 1970.

The Environmental Science Services Administration (ESSA) was a United States Federal executive agency created in 1965 as part of a reorganization of the United States Department of Commerce. [1] Its mission was to unify and oversee the meteorological, climatological, hydrographic, and geodetic operations of the United States.
