After launch in late 2008, NASA's Solar Dynamics Observatory (SDO) will help scientists to better understand solar variability and aid in predictions of space weather. SDO will also mark a new era in the delivery of high volumes of science data. To accommodate all the data, the new 18-meter Ka band dishes wait in readiness at the White Sands Testing Facility in New Mexico as engineers test and review operations.
