Movement of water around the glob (With the help of Satellite).

Earth, the water planet. Its lakes, rivers, and oceans hold a crucial element for life. Earth-orbiting satellites help us track and better understand how this water moves around the globe. #WorldWaterDay
Groundwater hidden from plain sight is a vital source of water that can be difficult to track. The GRACE-FO mission detects subtle changes in Earth’s gravity caused by the movement of water, like from groundwater and polar ice.

Our favorite fruits, veggies, and grains depend on water. NASA missions like SMAP and ECOSTRESS monitor soil moisture and drought, giving farmers a more complete picture and informing agricultural decisions.
