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.

In a recent study, scientists found that a previously unmeasured source – water percolating through soil and fractured rock below California’s Sierra Nevada mountains – delivers an average of 4 million acre feet (5 cubic kilometers) of water to the state’s Central Valley each year. This underground source accounts for about 10% of all the water that enters this highly productive farmland each year from every source (including river inflows and precipitation).
NASA Measures Underground Water Flowing From Sierra to Central Valley
Researchers have untangled puzzling patterns of sinking and rising land to pin down the underground locations where water is being pumped for irrigation.

Decades of drought across the U.S. Southwest has led some scientists to classify the intense, prolonged dryness as a “megadrought.” But drought in North America took a different shape in 2021, affecting areas that do not face long-term or intense drought as often. The northern Great Plains has been coping with drought for months.
