NASA launches satellites to track world’s water
By Ian James, Desert Sun
For 15 years, two NASA satellites revealed an unprecedented picture of movements in water around the Earth, tracking ice sheets melting, glaciers retreating, oceans rising and groundwater declining as humans drain aquifers.
Now, NASA is carrying on the mission with the next generation of satellites that will monitor changes in the world’s water supplies.
The twin satellites soared to orbit on a SpaceX Falcon 9 rocket that blasted off Tuesday from California’s Vandenberg Air Force Base.
