The best way to track the moisture in the dirt under your feet is to scan it from space.
That’s the mission for NASA’s SMAP satellite, which just made it safely to orbit.
The orbiter launched aboard a Delta 2 rocket on Saturday. It was NASA's third try after rough weather, and then mechanical trouble forced delays earlier this week.
