Parag Vaze, project manager, NASA’s Jet Propulsion Laboratory in Pasadena, participates in a prelaunch news conference for the Sentinel-6 Michael Freilich mission at Vandenberg Air Force Base in California on Nov. 20, 2020. The Sentinel-6/Jason-CS (Continuity of Service) mission consists of the Sentinel-6 Michael Freilich satellite, which will be followed by its twin, the Sentinel-6B satellite, in 2025. The Sentinel-6/Jason-CS mission is part of Copernicus, the European Union’s Earth observation program, managed by the European Commission. Continuing the legacy of the Jason series missions, Sentinel-6/Jason-CS will extend the records of sea level into their fourth decade, collecting accurate measurements of sea surface height for more than 90% of the world’s seas, and providing crucial information for operational oceanography, marine meteorology, and climate studies. Sentinel-6 Michael Freilich launched Nov. 21, 2020, at 9:17 PST (12:17 EST). NASA’s Launch Services Program at Kennedy Space Center was responsible for launch management.
