Jason-3 Launch

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...

For NASA JPL engineer Parag Vaze, studying Earth’s rising ocean has been a career three decades in the making.

Jason-3 on the Launch Pad

After living in coastal Virginia and seeing the effects of climate change firsthand, Ben Hamlington is now researching sea level rise at NASA JPL.

This animation illustrates the evolution of sea surface temperature (SST) anomalies (relative to the respective normal state) in the Pacific Ocean associated with the 2015-2016 El Niño.

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

The SpaceX Falcon 9 rocket carrying the Sentinel-6 Michael Freilich spacecraft lifts off from Space Launch Complex 4 at Vandenberg Air Force Base in California, Nov. 21, 2020, at 9:17 a.m. PST

The joint U.S.-European Sentinel-6 Michael Freilich is the next in a line of Earth-observing satellites that will collect the most accurate data yet on sea level and how it changes over time. With ...
