NASA and its European partners are set to launch the Sentinel-6B Earth satellite, which will track sea levels across more than 90% of the world's oceans. The mission is a vital component of NASA's efforts to monitor sea level rise and support public safety, city planning, and defense interests.
The launch, which is targeted for November 17 at 12:21 a.m. EST, will take place from Vandenberg Space Force Base in California on a SpaceX Falcon 9 rocket. The satellite, measuring 19.1 feet long and 7.74 feet high, weighs around 2,600 pounds when loaded with propellant.
Once the rocket lifts off, the main engine cuts off, followed by the separation of the first and second stages. The reusable first stage then begins its automated boost-back burn to the launch site for a powered landing. About three minutes after liftoff, the payload fairing separates and falls safely back to Earth.
The satellite will orbit the Earth every 112 minutes at 4.5 miles per second, eventually taking over from its twin, Sentinel-6 Michael Freilich, which was launched five years ago. The mission aims to gather data on sea level measurements, atmospheric conditions, and other oceanic phenomena to support a wide range of applications.
Scientists will use the satellite's data to build an accurate picture of local and global sea surface heights, supporting storm forecasting, secure coastal infrastructure, and commercial activities such as shipping. Researchers also plan to use Sentinel-6 Michael Freilich's measurements for different purposes, including mapping seafloor features.
The launch marks the first international involvement in Copernicus, the European Union's Earth Observation Programme, and represents a significant collaboration between NASA, ESA, EUMETSAT, NOAA, and other organizations.
