On January 21, 2017, the LASP-built Extreme Ultraviolet and X-Ray Irradiance Sensors (EXIS) on the National Oceanic and Atmospheric Administration (NOAA) GOES-16 satellite observed solar flares.
Solar flares are huge eruptions of energy on the sun and often produce clouds of plasma traveling more than a million miles an hour. When these clouds reach Earth they can cause radio communications blackouts, disruptions to electric power grids, errors in GPS navigation, and hazards to satellites and astronauts.
A multimillion dollar CU-Boulder/LASP instrument package expected to help scientists better understand potentially damaging space weather is now slated to launch aboard a National Oceanic and Atmospheric Administration satellite on Saturday, Nov. 19.
Designed and built at LASP, the instrument suite known as the Extreme Ultraviolet and X-ray Irradiance Sensors (EXIS) is the first of four identical packages that will fly on four NOAA weather satellites in the coming decade. EXIS will measure energy output from the sun that can affect satellite operations, telecommunications, GPS navigation and power grids on Earth as part of NOAA’s next-generation Geostationary Operational Environmental Satellites-R Series (GOES-R).
A multimillion dollar LASP instrument package to study space weather has passed its pre-installation testing and is ready to be incorporated onto a National Oceanic and Atmospheric Administration satellite for a 2015 launch.
