Jason-1 Launch - Artists Concept

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. These ob...

The Jason-3 satellite, launched on January 17, 2016, is allowing scientists to continue a 23-year record of crucial ocean monitoring.

Jason-3 Satellite Prepared For Launch

Sentinel-6 Michael Freilich will join a long-standing family of Earth observing satellites from NASA and European partners.

In many communities in the U.S., sea level rise is already a factor in people’s lives in the form of high-tide flooding.
