NASA and its U.S. and international partners have teamed up to launch a new Earth-observing satellite called Sentinel-6B that will measure sea surface height of most of the planet’s ocean.

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.
