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.

Flight System Systems Engineer
"As a young kid, I was captivated by the Apollo moon landings. I started to draw plans of rockets and read anything I could find on spaceflight. I loved taking things apart and marveled at their design. And that's when I knew I wanted to become an engineer. ... One aspect of the GRACE Follow-On mission that fascinates me is its ability to elegantly measure and uncover what is not visible to the naked eye. Measuring gravity and its changes over time and space is an important contribution to understanding our planet Earth."
