For 15 years, the GRACE mission has unlocked mysteries of how water moves around our planet. It gave us the first view of underground aquifers from space, and shows how fast polar ice sheets and mo...
15 Years of GRACE Earth Observations
The force of gravity not only keeps us from floating away, it also lets NASA study Earth’s water and ice from space. Using a pair of twin satellites named "GRACE," we can monitor our planet’s water.
