The Sentinel-6 Michael Freilich (launched November 2020) and Sentinel-6B make up the Sentinel-6 mission, also known as Jason Continuity of Service (Jason-CS), which is a partnership between NASA, NOAA, ESA, and EUMETSAT. This mission continues the long-term global sea surface height data record begun by first Jason satellites in 1992.
SENTINEL-6B was lifted into orbit during the mission ‘Falcon 9 Block 5 | Sentinel-6B’, on board a Falcon 9 space rocket.
The launch took place on Nov. 17, 2025, 5:21 a.m. from Space Launch Complex 4E.
