Caption

The twin satellites of NASA's Gravity Recovery and Climate Experiment (GRACE), active between 2002 and 2016, made detailed measurements of Earth's gravity field, enabling discoveries about gravity and Earth's natural systems. A new study that used GRACE data, coupled with data from other satellites and published reports of human activity, determined global-scale changes in Earth's freshwater supplies.
