Coming this month is the lecture I’ve been waiting for.  On January 27 I’ll learn how NASA finds water using satellites instead of this old method of dowsing with a forked stick.

Since 2002 NASA’s paired GRACE satellites have been circling the globe measuring Earth’s gravitational pull.  What they’ve also discovered is a way to measure groundwater.

How do they do it?  Learn more here in my January 2014 blog post:  Dowsing From Outer Space.
