The Geostationary Operational Environmental Satellite – R Series Program (GOES-R+) is a key element of NOAA operations. The GOES-R+ series of satellites—which includes the R, S, T, and U satellites—is flying improved spacecraft and instrument technologies, for more timely and accurate weather forecasts. The program is improving the detection and observation of meteorological phenomena that directly affect public safety, protection of property, and economic health and development.

LASP Roles

LASP provides:

  • The Extreme ultraviolet/X-ray Irradiance Sensors (EXIS)
  • EXIS Lead Scientist, Frank Eparvier
  • Four flight models for the mission

LASP Instrument

EXIS consists of an Extreme Ultraviolet Sensor (EUVS), an X-Ray sensor (XRS) and a combined EUVS/XRS electronics box (EXEB) to control subsystems and to do command and data handling interface with the GOES-R spacecraft. (Courtesy LASP)

The EXIS instrument detects solar soft X-ray irradiance (with the X-Ray Sensor, or XRS) and solar extreme ultraviolet spectral irradiance (with the Extreme Ultraviolet Sensor, or EUVS). XRS helps predict proton events and monitors solar flares that can disrupt communications and degrade navigational accuracy. EUVS monitors solar variations that directly affect satellite drag/tracking and ionospheric changes, which impact communication and navigation operations. EXIS is providing one of the most important observations for early warning of space weather events.
