Satellite Launch Eyes Ocean Health

On November 16, 2025, NASA in partnership with SpaceX, successfully launched the Sentinel-6B satellite aboard a Falcon 9 rocket from Vandenberg Space Force Base, California. This pivotal mission aims to enhance ocean and atmospheric monitoring, crucial for improving hurricane forecasts and safeguarding coastal infrastructure.

The launch, occurring at 9:21 p.m. PST, marks a significant step in international collaboration with contributions from the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), and the National Oceanic and Atmospheric Administration (NOAA). Approximately 90 minutes post-launch, Sentinel-6B established communication with a ground station in northern Canada, confirming the satellite’s operational status.

Sentinel-6B is set to build on the legacy of its predecessor, Sentinel-6 Michael Freilich, by providing precise sea-level measurements. This data is vital for U.S. flood predictions and supports a range of applications from commercial shipping to national defense. The satellite’s capabilities extend to measuring wind speeds, wave heights, and other atmospheric conditions which are essential for forecasting marine weather and understanding climate impacts.

The mission underscores the importance of international cooperation in space ventures. “This achievement demonstrates what can be accomplished when international agencies and industries work together toward a shared goal,” stated Simonetta Cheli, director of ESA’s Earth Observation Programmes. Sentinel-6B will continue collecting high-precision ocean data, playing a crucial role in global climate monitoring and supporting decisions that protect coastal communities worldwide.

As it reaches its operating altitude, Sentinel-6B will closely follow Sentinel-6 Michael Freilich, ensuring continuity in collecting and calibrating critical environmental data. This mission not only showcases cutting-edge technology but also reinforces the commitment of multiple nations to monitor and respond to the changing dynamics of Earth’s oceans.
