The NASA SMAP (Soil Moisture Active Passive) program is a satellite mission designed to measure and map Earth’s soil moisture. Launched in January 2015, SMAP carries both an active radar and a passive radiometer to collect data on soil moisture, soil freeze/thaw cycles, and vegetation water content on a global scale. This data is used by scientists and agricultural professionals to better understand and manage Earth’s water resources. The SMAP mission is currently still active and continues to provide valuable data to aid in the understanding of the Earth’s water cycle.
