Overview

Destination: Low Earth Orbit
Mission: Earth Science

Low Earth Orbit Space Launch Complex 4E Vandenberg SFB, CA, USA Probability: 90%
B1097 - Landing Zone 4

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.
