Dec 31, 2014: It's active. It's passive. And it's got a big, spinning lasso. Scheduled for launch on Jan. 29, 2015, NASA's Soil Moisture Active Passive (SMAP) instrument will measure the moisture lodged in Earth's soils with an unprecedented accuracy and resolution. The instrument's three... Read More
