Starting this year, NASA will be able to determine the soil moisture of the entire planet. It won’t be done using a giant finger sticking into to the soil, though. The space agency will use something more sophisticated than that. They have created equipment called the Soil Moisture Active Passive, or SMAP, satellite. It’s going to space on January 29, 2015, at 6:20 am Pacific Time from California’s Vandenberg Air Force Base.
Farmers won’t have to turn to other methods to know the moisture of their soil. The eye in the sky will do it for them. No more riding on a horse or tractor to do it. NASA’s computers will supply them the data right there in their living rooms.
