Aquarius maps soil moisture on This Week @NASA

Data from NASA’s Aquarius instrument has helped researchers create worldwide maps of soil moisture, showing how the wetness of the land fluctuates with the seasons and weather phenomena. Soil moisture, the water contained within soil particles, is an important player in Earth’s water cycle. When it launched in June 2011, the primary science objective of the Aquarius mission was to study the salt content of ocean surface waters. But investigators have since developed a method to retrieve soil moisture data from the instrument’s microwave radiometer. Also, SLS Core Preliminary Design Review, JWST update and Dry ice gullies on Mars.
