Be a NASA virtual guest for the launch of the Sentinel-6B mission. Sentinel-6B will provide global sea surface height measurements that will improve climate models, hurricane tracking, and our understanding of phenomena like El Niño. A collaboration between NASA , NOAA (National Oceanic and Atmospheric Administration, and ESA (European Space Agency), the spacecraft will take the baton from its twin, Sentinel-6 Michael Freilich, which launched in 2020. Together, these satellites extend a nearly three-decade record of global sea surface height measurements by another 10 years.

The Sentinel-6B mission is currently targeted to launch in November 2025 on a SpaceX Falcon 9 rocket from Space Launch Complex 4E at Vandenberg Space Force Base in California.
