The University of Colorado (CU) Laboratory for Atmospheric Physics (LASP) always finds a way to work an image of the CU Boulder mascot Ralphie, an American Bison, into everything they build-- including an instrument on GOES-16!
Ralphie is quite literally front-and-center on GOES-16's Extreme Ultraviolet and X-Ray Irradiance Sensors, or EXIS. The sensors are critical to understanding and monitoring solar irradiance in the upper atmosphere, that is, the power and effect of the sun's electromagnetic radiation per unit of area.
The buffalo image is integrated into their mirrored blanket support bracket located on the front of the EXIS EUVS subsystem, seen here in this picture. Learn more about EXIS.
