NASA is on the cusp of launching a vital Earth satellite, Sentinel-6B, which will track sea levels across over 90% of the planet's oceans. The mission, a collaboration between NASA and the European Space Agency (ESA), has been years in the making.
The rocket carrying Sentinel-6B, launched atop a SpaceX Falcon 9, is set to blast off from Vandenberg Space Force Base in California at 12:21 am EST on Monday, November 17. Once airborne, the satellite will embark on a 57-minute sequence of events that culminate in its separation from the rocket.
Upon reaching orbit, Sentinel-6B will begin its real work, tracking sea levels with unprecedented precision. The satellite's data will be used to refine atmospheric models supporting the safe re-entry of NASA's Artemis astronauts, protect coastal infrastructure, and improve public safety through storm forecasting and commercial activities such as shipping.
The mission marks a significant milestone in the continuation of a 30-year-plus record of sea-level measurements. Sentinel-6B will orbit the Earth every 112 minutes at an altitude of 4.5 miles (7.2 kilometers) per second, providing crucial data to help build an accurate picture of local and global sea surface heights.
As the satellite assumes its role as primary sea level measurer, researchers plan to use measurements from its twin, Sentinel-6 Michael Freilich, for different purposes, including mapping seafloor features.
The launch is expected to be broadcast live on NASA's website, with streaming video and photos available shortly after liftoff. Follow-up coverage will be available on the agency's blog, plus.nasa.gov/scheduled-events, and social media channels.
Sentinel-6B is part of a U.S.-European mission that showcases the collaborative efforts between NASA and the ESA in the field of Earth observation. The Copernicus Sentinel-6/Jason-CS (Continuity of Service) mission has received funding support from the European Commission, technical expertise from France's space agency CNES, and contributions from the National Oceanic and Atmospheric Administration (NOAA).
The satellite is equipped with three science instruments built by a division of Caltech in Pasadena, including the Advanced Microwave Radiometer, Global Navigation Satellite System β Radio Occultation, and Laser Retroreflector Array. NASA will provide launch services, ground systems supporting operation of the NASA science instruments, and support for U.S. members of the international Ocean Surface Topography and Sentinel-6 science teams.
As the world's oceans continue to rise due to climate change, missions like Sentinel-6B play a critical role in monitoring sea levels and predicting weather patterns. The success of this mission will have far-reaching implications for public safety, coastal infrastructure protection, and our understanding of the Earth's systems.
