Sea Surface Height 1993 - 2011

To provide scientists with essential information about global and regional changes in the seas, NASA will launch the Jason-3 satellite from Vandenberg Air Force Base in California.

On the left is Sea Surface Height Anomalies (SSHA) relative to the sea level mean (1993-2018). On the right is Global Mean Sea Level (GMSL) with the sea level trend as the straight line. The data a...

Recorded live launch broadcast of Sentinel-6 Michael Freilich

The ocean-observing Sentinel-6 Michael Freilich satellite launched from Vandenberg Air Force Base in California aboard a SpaceX Falcon 9 rocket on Nov. 21, 2020 at 12:17 p.m. EST

A SpaceX Falcon 9 rocket lifts off from Space Launch Complex 4 at Vandenberg Air Force Base carrying the Jason-3 spacecraft. Liftoff was at 10:42 a.m. PST (1:42 p.m. EST).

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

Growing up in landlocked Zimbabwe, NASA JPL engineer Shailen Desai was far from the ocean but still experienced its effects on the climate. Now, he is contributing to an international effort to tra...

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

SSH and SST - Pacific Ocean

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

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.

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

Watch the Jason-3 Mission Briefing from Friday, Jan 15, 2016 - panelists gave an overview of the Jason-3 mission.

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.

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

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

It's hard to "see" sea level rise by just looking at the ocean, but its effects are very real.
