NASA - National Aeronautics and Space AdministrationPasadena, CA – After 14 years of monitoring Earth’s main energy source, radiation from the sun, NASA’s Active Cavity Radiometer Irradiance Monitor satellite has lost contact with its ground operations team at NASA’s Jet Propulsion Laboratory, Pasadena, California, and its mission has been declared completed.

AcrimSat’s ACRIM 3 instrument was the third in a series of satellite experiments that have contributed to a critical data set for understanding Earth’s climate: the 36-year, continuous satellite record of variations in total solar radiation reaching Earth, or total solar irradiance.
