The SpaceX Falcon 9 rocket, topped with the Sentinel-6 Michael Freilich satellite secured inside its payload fairing, is rolled to Space Launch Complex 4 at Vandenberg Air Force Base in California on Nov. 20, 2020, in preparation for launch. 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.

The Sentinel-6 Michael Freilich satellite, secured inside a shipping container, arrives at Vandenberg Air Force Base in California on Sept. 24, 2020, aboard an Antonov cargo aircraft. The mission is an international partnership and the first launch of a constellation of two satellites that will observe changes in Earth’s sea levels for at least the next decade. Launching atop a SpaceX Falcon 9 rocket, Sentinel-6 Michael Freilich is targeted to lift off from Vandenberg’s Space Launch Complex 4 on Nov. 10, 2020.

Family members of Dr. Michael Freilich, for whom the Sentinel-6 Michael Freilich satellite is named, gather at Vandenberg Air Force Base in California on Nov. 20, 2020, the day before the spacecraft’s planned launch atop a Falcon 9 rocket. Freilich served as director of NASA’s Earth Science Division in the Science Mission Directorate at the agency’s Headquarters from 2006 until his retirement in 2019. A tireless advocate for advancing satellite measurements of the ocean, he was instrumental in advancing ocean altimetry and helped drive the evolution of NASA Earth science from a program that launched an Earth-observing space mission every few years to one that launches several missions each year. Freilich died Aug. 5, 2020, of pancreatic cancer. Sentinel-6 Michael Freilich launched Nov. 21, 2020, at 9:17 a.m. PST (12:17 p.m. EST).

Marina Jurica of NASA’s Jet Propulsion Laboratory in Pasadena moderates a science briefing 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.
