What happened
On November 16, 2025, NASA and SpaceX launched the Sentinel-6B satellite from Vandenberg Space Force Base in California. This satellite is designed to monitor ocean and atmospheric conditions, which will improve hurricane forecasts and protect coastal infrastructure. Sentinel-6B will replace the Sentinel-6 Michael Freilich satellite, which has been providing essential sea level measurements since its launch in 2020. The satellite is part of a collaborative effort involving NASA, ESA, EUMETSAT, and NOAA. It will collect data on wind speeds, wave heights, and atmospheric conditions, which are vital for understanding climate change and marine weather. The satellite's advanced instruments will measure ocean surface heights with high precision, aiding in flood predictions and supporting commercial shipping and fishing operations. Sentinel-6B will orbit Earth approximately 13 times a day, ensuring continuous data collection for coastal communities and decision-makers.
