Sea level rise is an indicator that our planet is warming. When ice on land, such as mountain glaciers or the ice sheets of Greenland or Antarctica, melts, that water contributes to sea level rise.

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.

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

The ocean is responsible for Earth's mild climate and makes life on Earth possible for all creatures.

NASA and its partners announced the renaming of the mission, previously known as Sentinel-6A/Jason-CS.

A key ocean observation satellite has been named after Earth scientist Michael Freilich
