    SMOS 10 years in orbit

    SMOS has been in orbit for a decade. This remarkable satellite has not only exceeded its planned life in orbit, but also surpassed its original scientific goals. It was designed to deliver data on soil moisture and ocean salinity which are both crucial components of Earth’s water cycle. By consistently mapping these variables, SMOS is not only advancing our understanding of the water cycle and the exchange processes between Earth’s surface and the atmosphere, but is also helping to improve weather forecasts and contributing to climate research as well as contributing to a growing number practical everyday applications.

    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.
