NASA SMAP satellite launched from Vandenberg AFB

PCWorld | Jan 31, 2015

NASA's Soil Moisture Active Passive (SMAP) observatory was launched from Vandenberg Air Force Base in California at 6:22am PST on January 31, 2015. SMAP will take the pulse of a key measure of our water planet: how freshwater cycles over Earth's land surfaces in the form of soil moisture. The mission will produce the most accurate, highest-resolution global maps ever obtained from space of the moisture present in the top 2 inches (5 centimeters) of Earth's soils. It will also detect and map whether the ground is frozen or thawed.
