Water is a resource vital to life, growth, and the health of our entire planet. Even our bodies are 75% water.  When there's a drought, and dry reservoirs, we worry, but what about water under the ground? Almost half of Americans get their drinking water from wells.  California pumps 11 billion gallons every day - 300 gallons for every person in the state! Can we detect underground droughts? NASA's GRACE satellites can. The two satellites, nicknamed "Tom" and "Jerry" chase each other endlessly around the earth and monitor their separation with incredible accuracy. When one flies over water-soaked ground there is more gravitational pull than from dry ground, and the satellite moves differently and NASA scientists can tell farmers and planners where the underground droughts are.  This video is a spectacular 360 degree full-dome presentation, with both animation and 360 degree video. It includes an interview with a young woman scientist who uses GRACE and invites viewers to consider a career like hers.
