Sentinel-6B launch

NASA is targeting 3:21 p.m. EST (9:21 p.m. PST) Sunday, Nov. 16 2025, for the launch of the Sentinel-6B satellite, the second of two identical satellites to head into Earth orbit five years apart to continue sea level observations for at least the next decade. Sentinel-6 Michael Freilich was launched in 2020.

Live launch coverage will be broadcasted on NASA Television and the agency's website, with prelaunch and science briefings the day before on Nov. 15, 2025.

Sentinel-6B will head into orbit on a SpaceX Falcon 9 rocket from the Vandenberg Air Force Base (VAFB) in California. The launch is managed by NASA's Launch Services Program, based at the agency's Kennedy Space Center in Florida. NASA's Jet Propulsion Laboratory in Southern California manages the agency's contribution to the mission.
