WebJan 10, 1991 · Launched in January 2015, the SMAP spacecraft (Figure 1) provides high spatial resolution radiometric and radar measurements of soil moisture and gravity freeze-thaw state. The SMAP radar and radiometer share a lightweight, deployable, reflector antenna system that rotates around the nadir axis and makes conical scans gravity of the … SMAP is a directed mission of the National Aeronautics and Space Administration. The SMAP project is managed for NASA by the Jet Propulsion Laboratory, with participation by the Goddard Space Flight Center. SMAP builds on the heritage and risk reduction activities of NASA's cancelled ESSP Hydros Mission. See more Soil Moisture Active Passive (SMAP) is a NASA environmental monitoring satellite that measures soil moisture across the planet. It is designed to collect a global 'snapshot' of soil moisture every 2 to 3 days. With this … See more SMAP provides measurements of the land surface soil moisture and freeze-thaw state with near-global revisit coverage in 2–3 days. SMAP surface measurements are coupled with hydrologic models to infer soil moisture conditions in the root zone.
