Sentinel-6 Michael Freilich launch

NASA is targeting 12:17 p.m. EST (9:17 a.m. PST) Saturday, Nov. 21, for the launch of the Sentinel-6 Michael Freilich satellite, the first of two identical satellites to head into Earth orbit five years apart to continue sea level observations for at least the next decade. Sentinel-6B will launch in 2025.

Live launch coverage will begin at 11:45 a.m. EST (8:45 a.m. PST), on NASA Television and the agency's website, with prelaunch and science briefings the day before on Nov. 20.

Sentinel-6 Michael Freilich will head into orbit on a SpaceX Falcon 9 rocket from Space Launch Complex 4 at 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.
