Sentinel-6B launch ahead

Sentinel-6B, the next sea-level monitoring satellite for the Copernicus Earth observation programme, is going to be launched on November 17, 2025 at MEZ 6:21 a.m. with a SpaceX Falcon 9 rocket from Vandenberg Space Force Base in California.

The Copernicus Sentinel-6 mission has become the gold standard reference mission to monitor and record this key consequence of climate change. Over the  past 25 years, the world’s oceans level has risen by almost 10 cm (Copernicus data).

Sentinel-6B will operate together with Sentinel-6 Michael Freilich, which was launched in 2020, during its first year, enabling greater accuracy with precise cross-calibration between the two instruments.

SpaceTech is proud to support this important international mission, empowering the two Sentinel 6 (Jason CS) satellites with large solar arrays. Each satellite set consist of two body mounted and two deployable panels combined in two solar array wings.
