Facts
About
Sentinel-6B is a radar altimeter satellite developed in partnership between several European and American organizations. It is part of the Jason satellite series and the Copernicus Programme. S6B includes a synthetic-aperture radar altimetry instrument designed to improve ocean topography measurements, as well as topography of rivers and lakes. The spacecraft is expected to operate for 5.5 years after entering service. The main objective of the Sentinel-6 mission is to measure sea surface topography with high accuracy and reliability to support ocean forecasting systems, environmental monitoring, and climate change monitoring. S6B was launched on a Falcon 9 rocket in November 2025.
