SpaceX is set to launch a Falcon 9 from Vandenberg Air Force Base in California on Saturday morning, with a target liftoff time of 9:17 AM PST (12:17 PM EST). This is the Sentinel-6 Michael Freilich Mission, which carries a satellite of the same name developed by the European Space Agency, NASA, and both U.S. and European meteorological monitoring bodies.

The Sentinel-6 is named for former NASA Earth Science Division Director Michael Freilich, who occupied the position between 2006 and 2019 and passed away in August. It’s one of two Sentinel-6-series satellites that will be launched for the program, with the Sentinel-6B set to join the Sentinel-6 Michael Freilich sometime in 2025.
