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 aim of the SWFO program is to ensure the robust continuity of space-based measurement of the critical space weather environment.

This will be accomplished by adding the capability to the existing Geostationary Operational Environmental Satellite-R Series Core Ground System.

These data are critical to support monitoring and timely forecasts of space weather events that have the potential to adversely impact elements vital to national security and economic prosperity, including telecommunication and navigation, satellite systems and the power grid.

NOAA is responsible for the ground segment including the acquisition, development, test and integration of the SWFO Command and control system.

[6] On 1 July 2020, on behalf of NOAA, NASA awarded the SWFO-L1 Solar Wind Plasma Sensor (SWiPS) contract to Southwest Research Institute (SwRI) in San Antonio, Texas.

[7] The SWFO-L1 satellite, which is planned to launch as a rideshare with the NASA Interstellar Mapping and Acceleration Probe (IMAP), will collect upstream solar wind data and coronal imagery to support NOAA's mission to monitor and forecast space weather events.
