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

Experts from NASA, ESA, EUMETSAT, and NOAA discuss the upcoming launch of Sentinel-6 Michael Freilich in a recorded live broadcast

For NASA scientist Severine Fournier, studying our planet knows no borders.

A look at how NASA is dealing with the threat of sea level rise to its coastal infrastructure.

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...

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 ...

Oceans of Climate Change

Fathoming the forces that determine global sea levels can be daunting. We present a guide to the basics of ocean surface topography.

This visualization shows total sea level change between 1992 and 2019, based on data collected from the TOPEX/Poseidon, Jason-1, Jason-2, and Jason-3 satellites. Blue regions are where sea level ha...

Greenland and Antarctica are home to most of the world's glacial ice – including its only two ice sheets – making them areas of particular interest to scientists.

Sea Surface Height - Global Average from 1993 - 2011.

Sea Level Isn't Level - Why it matters

Watch the Jason-3 Science Briefing from Friday, Jan 15, 2016 - panelists discussed the science and research of the Jason-3 mission.

TOPEX/Poseidon Instruments

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...

Earth’s global sea levels are rising – and are doing so at an accelerating rate.

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

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.
