X-ray Irradiance Sensors (EXIS) were installed on the sun-pointing platform. They will observe the sun and space weather, including coronal mass ejections, solar flares and ion fluxes that can disrupt power grids, communication and navigation systems and create radiation hazards.
The space weather mission is an important part of not only the overall GOES-R Series Program, but also NOAA's National Weather Service (NWS), which is home to the Space Weather Prediction Center. Space weather describes the conditions in space that affect Earth and its technological systems. Space weather storms originate from the sun and occur in space near Earth or in the Earth's atmosphere.
Installation of the SUVI and EXIS instruments moves the program another step closer to the launch of the GOES-R satellite in early 2016. In addition to SUVI and EXIS, the Advanced Baseline Imager (ABI) and the Space Environment In-Situ Suite (SEISS) were delivered for integration earlier this year and will be installed on the spacecraft in the coming months. The two remaining instruments that complete the GOES-R Series Program payload are the Magnetometer and Geostationary Lightning Mapper (GLM). Both instruments are scheduled for delivery later this year.
