Workers transport the international Sentinel-6B satellite, encapsulated in the SpaceX Falcon 9 payload fairing, from the Astrotech Space Operations Facility to Space Launch Complex 4 East at Vandenberg Space Force Base in California on Wednesday, Nov. 12, 2025. A collaboration between NASA, ESA (European Space Agency), EUMETSAT (European Organisation for the Exploitation of Meteorological Satellites), and the National Oceanic and Atmospheric Administration (NOAA), Sentinel-6B is designed to measure sea levels down to roughly an inch for about 90% of the world’s oceans. NASA is targeting Sunday, Nov. 16, 2025, for launch.
