Jason-3 Animation

On Aug. 26, 2015 at 9:30 a.m. PT, NASA hosted a media teleconference to discuss recent insights on sea level rise and the continuing challenge of predicting how fast and how much sea level will ris...

TOPEX/Poseidon over Earth

This video discusses the water cycle, which is the movement of water around the Earth, and its importance to life. Changes to the water cycle affect climate and vice versa.

Jason-CS/Sentinel-6 - How they will work

Changing conditions in the Pacific have stirred up Earth’s largest ocean and redistributed its heat, piling up warm waters along U.S. Western shores and raising sea level in the process.

It’s not only water processes that play a role in global sea level rise – ground movements can play a significant role as well.

In this illustration, the Sentinel-6 Michael Freilich spacecraft - the world's latest sea-level satellite - orbits Earth with its deployable solar panels extended.

Jason-3 Satellite Prepared For Launch

Earth’s rising seas are some of the most visible signs of our warming planet. Over the last 23 years, NASA satellite missions have observed a steady rise in global sea levels as polar ice sheets me...

For NASA engineer Shannon Statham, building spacecraft is all about being creative.

The Jason-2 satellite sees something brewing in the Pacific. Researchers say it could be a significant El Niño with implications for global weather and climate.
