NOAA’s SOLAR-1 enters operational service as first dedicated U.S. space weather satellite
NOAA’s Space Weather Observations at L1 to Advance Readiness-1 (SOLAR-1) observatory has entered operational service, becoming the first U.S. satellite dedicated exclusively to continuous operational space weather observations. The spacecraft is stationed at the Sun-Earth Lagrange Point 1 (L1), where it monitors solar wind conditions and coronal mass ejections moving away from the Sun and toward Earth.
