Two GOES-R Instruments Complete Spacecraft Integration

Posted May 30, 2014

Two of the six instruments that will fly on NOAA’s first Geostationary Operational Environmental Satellite – R (GOES-R) satellite have completed integration with the spacecraft. The Solar Ultraviolet Imager (SUVI) and Extreme Ultraviolet and 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.

“This development highlights the forward progress underway to complete the installation of the space weather instrument suite onto the GOES-R spacecraft,” said Pam Sullivan, GOES-R Flight Project Manager at NASA Goddard Space Flight Center, Greenbelt, Maryland. “It is critical we give our partners at NOAA’s Space Weather Prediction Center the tools they need to improve prediction capabilities and further our knowledge of space weather.”

Understanding Space Weather

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.

In addition to monitoring weather on Earth, the GOES-R satellites will monitor weather in space caused by electromagnetic radiation and charged particles released from solar storms on the Sun. Pilots, farmers, satellite operators, electric power workers and astronauts rely on space weather data.

Space weather can be difficult to understand since it is unlike the weather we experience here on Earth. For example, one type of space weather, known as coronal mass ejections, can have changing polarities, which can make it more challenging to predict the impacts of the magnetic storm. Watch here to learn more about how space weather impacts our everyday lives. To help kids understand space weather, the GOES-R Program partnered with NASA to create materials availablehere for students and teachers.

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.
