Geostationary Extended Observations

Last updated

The Geostationary Extended Observations (GeoXO) satellite system is the National Oceanic and Atmospheric Administration (NOAA)'s planned replacement for the existing Geostationary Operational Environmental Satellite (GOES) satellites. These new geostationary satellites will make weather, ocean, and climate observations. The project aims to begin observations in the early 2030s as the GOES-R satellites reach their operational lifetime. The first GeoXO satellite is scheduled to be launched in 2032, with two more following in 2035. [1]

NASA is developing the satellites and awarded multiple "Phase A" contracts in 2021 and 2022, [2] including ones with Lockheed Martin and Maxar to study using their LM-2100 and 1300-class satellite busses, respectively. [3] [4] The program was official approved by the United States Department of Commerce in December 2022, [5] moving the program from the study phase to the development phase, and in March 2023 NASA and NOAA awarded L3Harris a $765.5 million contract to develop the first two GeoXO Imager (GXI) instruments.

Space Weather Follow On-Lagrange 1 (SWFO-L1) is a future spacecraft mission planned to monitor signs of solar storms, which may pose harm to Earth's telecommunication network. The spacecraft will be operated by the National Oceanic and Atmospheric Administration (NOAA), with launch scheduled for February 2025. It is planned to be placed at the Sun–Earth L1 Lagrange point, a location between the Earth and the Sun. This will allow SWFO-L1 to continuously watch the solar wind and energetic particles heading for Earth. SWFO-L1 is an ESPA Class Spacecraft, sized for launch on an Evolved Expendable Launch Vehicle Secondary Payload Adapter (ESPA) Grande ring in addition to the rocket's primary payload. The spacecraft's Solar Wind Instrument Suite (SWIS) which includes three instruments will monitor solar wind, and the Compact Coronagraph (CCOR) will monitor the Sun's surroundings to image coronal mass ejection (CME). A CME is a large outburst of plasma sent from the Sun towards interplanetary space.
