On January 29, 2015, NASA has planned to launch spacecraft that will track soil moisture worldwide. The Jet Propulsion Lab in Pasadena and the Goddard Spaceflight Center in Maryland have developed a soil measurement observatory known as SMAP (Soil Moisture Active Passive).
SMAP researcher Dr. Dara Entekhabi shared that SMAP will allow both in daylight and also during night. Also, one would be able to see through clouds. After every three days, SMAP will map soil moisture on earth and will notice parts that are drying out and also, the places that are becoming wetter.
