NASA's Soil Moisture Active Passive mission is scheduled to launch from Space Launch Complex 2 on Vandenberg Air Force Base.

NASA's Soil Moisture Active Passive mission, or SMAP, is scheduled to launch in November 2014 from Space Launch Complex 2 on Vandenberg Air Force Base in California, seen here on a temperate, fog-free summer's day.

A United Launch Alliance Delta II rocket will be used to deliver SMAP into orbit. SMAP will provide global measurements of soil moisture and its freeze/thaw state. These measurements will be used to enhance understanding of processes that link the water, energy and carbon cycles, and to extend the capabilities of weather and climate prediction models. SMAP data also will be used to quantify net carbon flux in boreal landscapes and to develop improved flood prediction and drought monitoring capabilities.
