Jason-1 Spacecraft Animation

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

Sea levels across the globe are rising as a result of a changing climate — and the rate at which they are rising is accelerating. NASA Science Live was recorded Tuesday, Nov. 17, 2020, and featured...

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

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.

Jason-1 Launch - Artists Concept

Global sea level rise is accelerating incrementally over time rather than increasing at a steady rate, as previously thought, according to a new study based on 25 years of NASA and European satelli...
