Ice covers 10 percent of Earth's surface and helps moderate the planet's temperature.

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

The Sentinel-6 Michael Freilich satellite sits in front of a testing chamber where mission team members tested whether the spacecraft could endure the loud sounds it will encounter during launch.

Here we provide side by side comparisons of Pacific Ocean sea surface height (SSH) anomalies of what is presently happening in 2015 with the Pacific Ocean signal during the famous 1997 El Niño.

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...
