This 8,500-acre federal reservation has ten giant dishes that track polar-orbiting satellites for the National Oceanic and Atmospheric Administration. The data is received here, then sent to the Satellite Operations Control Center in Suitland, Maryland, for interpretation. The information can be used for predicting weather, finding missing ships, analyzing depletion of fisheries, studying holes in the ozone, monitoring volcanic activity and a host of other projects. Tours explain the impressive technology.
