Sentinel-6B Launch

Live coverage of prelaunch and launch activities for Sentinel-6B, an international mission delivering critical sea level and ocean data to protect coastal infrastructure, improve weather forecasting, and support commercial activities at sea.

Sentinel-6

With global mean sea level rising because of climate change, Copernicus Sentinel-6 is the next radar altimetry reference mission to extend the legacy of sea-surface height measurements until at least 2030. The satellite carries a Poseidon-4 radar altimeter and a microwave radiometer.

SpaceX

SpaceX designs, manufactures and launches advanced rockets and spacecraft. The company was founded in 2002 to revolutionize space technology, with the ultimate goal of enabling people to live on other planets.

Overview

Destination: Low Earth Orbit
Mission: Earth Science

Low Earth Orbit Space Launch Complex 4E Vandenberg SFB, CA, USA
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.
