Tracking Earth's water in motion

GRACE Follow-on (GRACE-FO) is continuing GRACE's legacy of tracking Earth's water movement to monitor changes in underground water storage, the amount of water stored in large lakes and rivers, soil moisture, ice sheets and glaciers, and sea level caused by the addition of water to the ocean. These discoveries provide a unique view of Earth's climate and have far-reaching benefits to society and the world's population.

"I actually didn't plan on being an engineer. I wanted to be a marine biologist. I got a job at the Department of Water and Power in the chemistry lab. I was looking at what the engineers were doing and they seemed to be having an awful good time."

"(Former JPL Director) von Karman said, 'Scientists discover the world that exists. Engineers create the world that never was.' ... That's the most rewarding thing for me."
